BERNOULLI
HEATING & COOLING

Heat pump products, efficiency ratings, permit requirements and incentive programs can change. Verify current information for the exact property, equipment combination, contractor and installation date before signing a contract.

The best heat pump is not automatically the most expensive model, the highest advertised efficiency rating or the equipment with the largest rebate. It is the system that matches the home’s heating and cooling loads, distributes air effectively, operates within the building’s electrical capacity and includes a clear installation and commissioning plan.

A useful heat pump proposal should explain what the system will serve, how it was sized, how much heating capacity it provides during colder weather, how supplementary heat will operate, what electrical and duct modifications are required and how performance will be verified after installation.

This heat pump buying guide gives BC homeowners 18 questions to answer before choosing equipment or approving an installation contract.

What Should You Look for When Buying a Heat Pump?

Start with the home and the project goals, not the manufacturer logo.

A Strong Heat Pump Proposal Should Address:

  • Heating and cooling loads
  • Whole-home or partial-home coverage
  • Cold-weather heating capacity
  • Minimum and maximum equipment output
  • Ductwork or indoor-zone design
  • Supplementary heating
  • Electrical capacity
  • Indoor and outdoor equipment locations
  • Condensate and defrost drainage
  • Permits and approvals
  • Exact equipment models
  • Commissioning
  • Warranty and future service

Do Not Compare Price Until You Compare Scope

Two quotes can use outdoor units with similar nominal capacities while proposing substantially different:

  • Indoor equipment
  • Duct modifications
  • Electrical work
  • Backup heating
  • Controls
  • Installation procedures
  • Commissioning

The lowest number at the bottom of the page is not necessarily the lowest-cost system over its service life.

1. What Do You Want the Heat Pump to Accomplish?

Define the project before selecting equipment.

Possible Goals Include:

  • Replace an aging furnace or boiler
  • Replace electric baseboard heating
  • Add air conditioning
  • Provide whole-home heating and cooling
  • Condition only selected rooms
  • Reduce fossil-fuel use
  • Improve comfort in an addition or basement suite
  • Provide backup for another heating system

Whole-Home and Partial-Home Projects Are Different

A partial-home system may serve:

  • Main living area
  • Upper floor
  • Home office
  • New addition

while other rooms retain existing heating.

A whole-home project needs a clear plan for every required space and peak heating conditions.

Decide Whether Existing Heating Will Remain

Possible strategies include:

  • Complete replacement
  • Dual-fuel operation
  • Retained electric baseboards in defined rooms
  • Boiler retained as supplementary heating
  • Independent backup system

Put the Goal in the Quote

The proposal should state whether the heat pump is intended to provide:

  • Primary whole-home heating
  • Partial heating
  • Cooling with heating support
  • Full heating and cooling with supplementary capacity

2. Which Heat Pump Configuration Fits the Home?

Air-source heat pumps are available in several configurations.

Central Ducted Heat Pump

A central indoor unit distributes conditioned air through ducts.

This can be a strong option when the home already has suitable:

  • Supply ducts
  • Return ducts
  • Room distribution
  • Equipment space

Single-Zone Ductless Heat Pump

One outdoor unit connects to one indoor unit.

This can work well for:

  • Open living areas
  • Additions
  • Suites
  • Individual problem rooms
  • Small homes with a suitable layout

Multi-Zone Ductless Heat Pump

One outdoor unit connects to several indoor units.

This can reduce the number of outdoor units but requires careful attention to:

  • Individual room loads
  • Minimum system capacity
  • Indoor-unit combinations
  • Refrigerant piping
  • Simultaneous zone demand

Concealed-Duct Heat Pump

A compact indoor air handler can serve several nearby rooms through short duct runs.

This can be useful for:

  • Bedroom groups
  • Upper floors
  • Homes where visible wall units are undesirable

Mixed System

A home can combine:

  • Central ducted equipment
  • Ductless zones
  • Concealed-duct zones
  • Retained supplementary heating

Do Not Force One System Type Into Every Building

The right configuration should follow the architecture and room-use pattern.

3. What Are the Home’s Heating and Cooling Loads?

A heat-load calculation estimates how much heating capacity the building requires under defined indoor and outdoor conditions.

Load Depends On:

  • Home size and geometry
  • Insulation
  • Windows and doors
  • Air leakage
  • Foundation and basement
  • Ceiling and roof construction
  • Local design temperature

Use a Recognized Calculation Method

Whole-home Canadian heat pump selection should use an appropriate recognized method, such as a CSA F280-based heating and cooling load calculation.

Square Footage Is Not Enough

Two houses with the same floor area can have very different:

  • Window area
  • Air leakage
  • Insulation
  • Exposure
  • Heating loads

The Old Furnace Size Is Not the Home’s Load

The existing furnace may have been:

  • Oversized when originally installed
  • Selected before insulation upgrades
  • Selected using older rules of thumb

Room-Level Loads Matter

For ductless and zoned systems, calculate or reasonably evaluate the requirements of individual:

  • Bedrooms
  • Living areas
  • Basements
  • Additions
  • Suites

Ask for the Load Report

The quote should not merely say that a calculation was completed. Ask for the resulting:

  • Heating load
  • Cooling load
  • Design conditions
  • Assumptions about planned renovations

4. How Much Capacity Does the Heat Pump Provide in Cold Weather?

Nominal tonnage does not show how much heat an air-source heat pump provides during cold outdoor conditions.

Ask for Published Heating Capacity At:

  • A mild heating condition
  • 0°C where available
  • A colder relevant condition
  • The local design temperature or the nearest available published condition

Compare Capacity With Building Load

The comparison should show:

  • How much heat the building needs
  • How much heat the proposed heat pump provides
  • When supplementary heat is expected to operate

Cold Climate Is Not a Complete Design

A cold-climate designation can be useful, but it does not prove the unit:

  • Is correctly sized
  • Serves every room
  • Has adequate ductwork
  • Meets the complete home load

Check Both Capacity and Efficiency

At a cold condition, ask about:

  • Heating output
  • Coefficient of performance where available
  • Capacity maintenance
  • Operating range

Do Not Demand Full Heat-Pump Capacity at Every Temperature Without Considering the Design Goal

Some projects intentionally use supplementary heat below a balance point.

The important issue is whether that strategy is:

  • Calculated
  • Clearly explained
  • Compatible with the homeowner’s cost and electrification goals

5. How Low Can the System Modulate?

Maximum output matters during cold weather.

Minimum output matters during mild weather.

Why Minimum Capacity Matters in BC

For much of the heating season, a Lower Mainland or Fraser Valley home needs only a fraction of its peak heating capacity.

A Low Minimum Capacity Can Help:

  • Reduce cycling
  • Maintain steady temperature
  • Reduce noise
  • Improve part-load operation

Variable-Speed Does Not Mean Unlimited Modulation

Every variable-capacity system still has a minimum operating output.

This Is Especially Important For:

  • Small homes
  • Condos
  • Well-insulated homes
  • Individual bedrooms
  • Multi-zone systems

Ask for the Operating Range

Compare the published minimum and maximum capacities for the exact equipment combination rather than relying only on nominal size.

6. Which Efficiency Ratings Are Being Compared?

Efficiency ratings answer different questions.

HSPF2

HSPF2 describes standardized seasonal heating efficiency.

When comparing Canadian winter efficiency, make sure the quoted value identifies the climate region, including whether it is:

  • HSPF2 Region IV
  • HSPF2 Region V

Do not compare values from different regions directly.

SEER2

SEER2 measures standardized seasonal cooling efficiency.

COP

COP compares useful heating output with electrical input at a particular operating condition.

A COP value should identify the applicable:

  • Outdoor temperature
  • Operating condition

Efficiency Is Not Capacity

A highly efficient heat pump can still be too small or too large for the home.

Compare the Exact Matched System

Performance ratings can depend on the combination of:

  • Outdoor unit
  • Air handler
  • Indoor coil
  • Ductless indoor units
  • Furnace where applicable

Ask for the AHRI Reference Where Applicable

The reference helps identify the certified equipment combination to which published ratings apply.

7. What Is the Supplementary-Heating Strategy?

A complete heating design should explain what happens when heat-pump capacity does not fully meet the building load or when the outdoor unit is unavailable.

Possible Supplementary Systems Include:

  • Electric resistance heat
  • Gas furnace
  • Retained electric baseboards
  • Retained boiler in a mixed system
  • Another independent heating system

Electric Resistance Backup

Ask:

  • What size heat kit is proposed?
  • How was that capacity selected?
  • What electrical load does it add?
  • When will the controls activate it?

Dual-Fuel Backup

Ask:

  • When will the furnace take over?
  • Is the changeover based on capacity or operating cost?
  • Can the heat pump and furnace operate together?
  • How will the thermostat control both systems?

Do Not Oversize Backup Heat by Habit

Excess electric backup capacity can increase:

  • Electrical-service requirements
  • Equipment cost
  • Potential peak electricity use

Ask About Emergency Operation

The homeowner should understand what heating remains available during an outdoor heat-pump fault.

8. Can the Existing Ducts Support the Required Airflow?

A central heat pump depends on the duct system attached to it.

Existing Duct Problems Can Include:

  • Small supply trunks
  • Insufficient return air
  • Restrictive filter cabinets
  • Poor transitions
  • Damaged flex duct
  • Duct leakage
  • Unbalanced room airflow

The Old Furnace Working Does Not Prove the Ducts Are Suitable

Heat pumps and furnaces can have different:

  • Airflow requirements
  • Supply-air temperatures
  • Blower profiles
  • Operating durations

Ask How the Ducts Were Evaluated

A professional assessment can include:

  • Duct measurements
  • External static pressure
  • Filter pressure drop
  • Airflow testing
  • Room distribution

Possible Improvements Include:

  • Larger return duct
  • Improved filter cabinet
  • Better transitions
  • Duct sealing
  • Branch repair
  • Room balancing

Do Not Approve a Larger Heat Pump Without Checking the Ducts

Higher airflow through restrictive ductwork can create:

  • Noise
  • Poor delivered airflow
  • Higher blower power
  • Equipment operating problems

9. How Will Every Important Room Be Served?

Total system capacity does not establish room-by-room comfort.

For a Ducted System, Ask:

  • Does every room have adequate supply airflow?
  • Is there an appropriate return-air path?
  • Are basement and upper-floor loads different?
  • Will balancing or duct modification be required?

For a Ductless System, Ask:

  • Can air reach closed bedrooms?
  • Can one head serve another floor?
  • What happens when interior doors are closed?
  • Will retained heating be needed in unserved rooms?

Capacity Is Not Distribution

An oversized living-room head does not create a reliable airflow path through walls and closed doors.

Possible Solutions Include:

  • Additional indoor units
  • Concealed ducting
  • Several single-zone systems
  • Central ducted system
  • Mixed system
  • Retained room heating

Design Around Actual Household Use

If bedroom doors remain closed at night, the system should be evaluated with that operating pattern in mind.

10. Does the Home Have Enough Electrical Capacity?

Heat pump electrical requirements depend on the exact equipment and supplementary-heating design.

Electrical Loads Can Include:

  • Outdoor unit
  • Indoor air handler
  • Ductless indoor equipment
  • Electric heat kit
  • Condensate pumps
  • Controls

Do Not Judge Capacity From Panel Size Alone

A home with a 100-amp service may have enough available capacity for a suitable project.

Another home with a larger service may already have substantial loads.

An Electrical Load Calculation Is Required

The electrical contractor should evaluate:

  • Existing demand
  • Proposed heat-pump load
  • Supplementary heat
  • Other major household equipment
  • Planned future loads

Tell the Contractor About Planned:

  • EV charger
  • Electric water heater
  • Induction range
  • Hot tub
  • Secondary suite
  • Home addition

A 200-Amp Upgrade Is Not an Automatic Requirement

Possible alternatives, where permitted and suitable, can include:

  • Accurate demand calculations
  • Load management
  • Removal of obsolete electrical loads
  • Appropriately sized supplementary heat
  • Building-envelope improvements

Request a Separate Electrical Scope

The quote should identify:

  • New circuits
  • Breakers
  • Disconnects
  • Panel work
  • Service upgrade if required
  • Items not included

11. Where Will the Outdoor Unit Be Installed?

Outdoor-unit location affects performance, sound, drainage and future service.

The Location Needs:

  • Manufacturer-required airflow clearance
  • Stable mounting
  • Service access
  • Protection from physical damage
  • Appropriate refrigerant-piping route
  • Safe defrost-water drainage

Avoid Locations With:

  • Tight decorative enclosures
  • Blocked discharge airflow
  • Heavy roof runoff
  • Persistent debris
  • Vehicle impact risk
  • Inadequate service clearance

Consider Sound and Vibration

Review proximity to:

  • Bedroom windows
  • Neighbouring patios
  • Property lines
  • Reflective walls
  • Vibration-sensitive structures

Plan Defrost Water

During winter heating, the outdoor unit can release water as frost melts.

Avoid draining toward:

  • Walkways
  • Stairs
  • Doorways
  • Neighbouring property
  • Areas where ice can become hazardous

Put the Location in Writing

The proposal should identify the agreed outdoor location, mounting method and routing rather than leaving those decisions until installation day.

12. Where Will Indoor Units and Drains Be Installed?

Ductless Indoor-Unit Placement

Consider:

  • Room circulation
  • Direct drafts onto occupants
  • Furniture obstruction
  • Filter access
  • Service access
  • Refrigerant-line routing
  • Condensate drainage

Avoid Selecting Location for Appearance Alone

An indoor unit placed in a visually discreet corner can perform poorly if airflow is blocked or directed away from the occupied space.

Central Air-Handler Location

Review:

  • Service clearance
  • Filter access
  • Drain-pan protection
  • Condensate route
  • Noise transmission
  • Duct transitions

Condensate Needs a Reliable Destination

The design may use:

  • Gravity drainage
  • Condensate pump
  • Approved plumbing connection

Ask About Water-Damage Protection

Depending on the location, appropriate measures can include:

  • Secondary drain pan
  • Overflow switch
  • Accessible condensate pump
  • Visible or safely terminated drain

Show Exterior Line Covers on the Proposal

The homeowner or strata should understand the planned route for:

  • Refrigerant piping
  • Drainage
  • Control wiring
  • Electrical conduit

13. Which Permits and Property Approvals Are Required?

Most residential heat pump installations involve regulated electrical work.

Possible Requirements Include:

  • Electrical permit
  • Gas permit when regulated gas equipment is modified or removed
  • Applicable refrigeration requirements
  • Municipal building or structural approval
  • Strata or co-op approval
  • Heritage or building-envelope approval

Permit Jurisdiction Can Vary

Depending on the property, the applicable authority can be:

  • Technical Safety BC
  • A municipality with its own inspection authority
  • Another authority having jurisdiction

Strata Approval Is Separate From a Permit

Written strata approval may be needed for:

  • Outdoor equipment
  • Exterior-wall penetrations
  • Balconies
  • Roofs
  • Common electrical infrastructure
  • Common or limited common property

The Contract Should State:

  • Which permits are expected
  • Who obtains them
  • Whether fees are included
  • Which inspections are required

Do Not Accept “Permits Are Not Usually Needed” as the Entire Explanation

The answer should be based on the actual equipment, property and jurisdiction.

14. Does the Quote Identify the Exact Equipment and Scope?

A professional quote should be specific enough that another informed person can understand what is being installed.

Equipment Information Should Include:

  • Outdoor model number
  • Indoor model number or numbers
  • Air handler or furnace model
  • Thermostat or controller
  • Electric heat-kit capacity where applicable
  • AHRI certified reference where applicable

Installation Scope Should Include:

  • Indoor-unit locations

The Project May Require:

  • Heat pump design and sizing
  • Refrigeration work
  • Electrical work
  • Gas work
  • Ductwork
  • Controls
  • Condensate drainage
  • Building-envelope penetrations

Ask Who Performs Each Scope

The main contractor may employ or subcontract:

  • Electrician
  • Gas contractor
  • Refrigeration mechanic
  • Sheet-metal worker
  • Other required specialists

Useful Questions Include:

  • Who is responsible for the load calculation?
  • Who applies for each permit?
  • Who performs the electrical work?
  • Who commissions the refrigeration circuit?
  • Who returns if performance problems appear?

Current Incentive Programs Can Have Additional Contractor Requirements

Verify program eligibility before committing to the contractor or equipment when an incentive is part of the project budget.

Experience With the System Type Matters

A contractor experienced with central ducted retrofits may not automatically have the same depth of experience with:

  • Multi-zone ductless design
  • Air-to-water systems
  • Condo installations
  • Complex dual-fuel controls

16. How Will the System Be Commissioned?

Commissioning verifies that the installed system operates as intended.

It Is More Than Confirming That the Equipment Turns On

Depending on system type, commissioning can include:

  • Correct equipment models
  • Heating operation
  • Cooling operation
  • Thermostat and controller setup
  • Indoor and outdoor fan operation
  • Duct airflow
  • External static pressure
  • Backup heat
  • Dual-fuel changeover
  • Condensate drainage
  • Refrigeration-system operation
  • Fault-code review

For Ducted Systems

Ask how the contractor will verify:

  • Blower configuration
  • Total airflow
  • Static pressure
  • Room distribution

For Ductless Systems

Every indoor unit should be checked for:

  • Heating
  • Cooling
  • Fan operation
  • Communication
  • Drainage
  • Controller operation

For Dual-Fuel Systems

Verify:

  • Heat-pump heating
  • Furnace heating
  • Changeover logic
  • Shared blower operation

Request Homeowner Training

The handover should explain:

  • Heat and Cool modes
  • Fan settings
  • AUX Heat
  • Emergency Heat where applicable
  • Defrost
  • Filter maintenance
  • Fault reporting

17. What Warranty and Service Support Are Included?

Warranty terms should be reviewed before purchase rather than after a component fails.

Ask About:

  • Parts warranty
  • Compressor warranty
  • Labour warranty
  • Registration requirements
  • Warranty exclusions
  • Transferability
  • Service-call charges

Parts Warranty Is Not Necessarily Complete Repair Coverage

The homeowner may still be responsible for:

  • Diagnosis
  • Labour
  • Refrigerant
  • Recovery and evacuation
  • Materials
  • Shipping

Ask Who Provides Future Service

Confirm whether the installer:

  • Services the brand
  • Handles warranty claims
  • Stocks or sources replacement parts
  • Provides ongoing maintenance

Parts Availability Matters

Modern heat pumps can depend on proprietary:

  • Control boards
  • Inverter assemblies
  • Fan motors
  • Controllers

Keep Documentation

Retain:

  • Final contract
  • Model and serial numbers
  • Paid invoice
  • Permit information
  • Warranty registration
  • Commissioning records

18. What Is the Complete Project Value?

Compare complete installed projects rather than outdoor-unit prices.

Project Cost Can Include:

  • Equipment
  • Labour
  • Ductwork
  • Electrical work
  • Backup heating
  • Controls
  • Refrigerant piping
  • Drainage
  • Permits
  • Equipment removal
  • Commissioning
  • Finish repairs

Operating Cost Depends on More Than Efficiency Rating

Actual energy use depends on:

  • Weather
  • Building heat loss
  • Thermostat setting
  • Equipment sizing
  • Backup-heat use
  • Duct leakage
  • Utility rates
  • Household use

Ask for Assumptions Behind Savings Estimates

A projection should identify:

  • Existing fuel or heating system
  • Energy rates used
  • Expected heat-pump efficiency
  • Supplementary-heating assumption
  • Home energy-use assumptions

Consider Long-Term Value

Include:

  • Comfort
  • Cooling capability
  • Noise
  • Warranty
  • Maintenance
  • Service support
  • Expected future repairs

Do Not Approve a Weak Design Solely Because It Has a Short Payback Estimate

A system that does not heat the intended rooms or requires repeated repair has poor value regardless of the original spreadsheet.

Buying a Central Ducted Heat Pump

Best Fit

A central system can be a strong option when the home has usable ductwork and the homeowner wants whole-home distribution from one indoor unit.

Before Buying, Verify:

  • Duct dimensions
  • Return-air capacity
  • External static pressure
  • Filter arrangement
  • Room airflow
  • Air-handler space
  • Backup-heating design

Ask About Supply-Air Expectations

Heat-pump supply air often feels less hot than air from a gas furnace while operating for longer periods.

Do Not Select the Outdoor Unit Separately From the Air Handler

Indoor equipment affects:

  • Capacity
  • Efficiency
  • Blower performance
  • Controls
  • Certified matching

Buying a Single-Zone Ductless Heat Pump

Best Fit

A single-zone system can suit:

  • Open living areas
  • Additions
  • Home offices
  • Suites
  • Individual comfort problems

Check Room Distribution

Determine whether the indoor unit can serve the actual occupied area without relying on air travelling through several closed rooms.

Check Minimum Capacity

A small room can require much less heating or cooling than the nominal indoor-unit size.

Check Indoor Placement

Avoid:

  • Direct drafts onto beds or seating
  • Furniture obstruction
  • Difficult filter access
  • Unreliable condensate routes

Check Outdoor Placement

Single-zone systems still require appropriate:

  • Airflow
  • Sound planning
  • Defrost drainage
  • Service access

Buying a Multi-Zone Heat Pump

Advantages Can Include:

  • Several indoor zones
  • Fewer outdoor units
  • Individual room controls

Important Design Questions Include:

  • What is each room’s load?
  • What is the outdoor unit’s minimum capacity?
  • What happens when only one small zone calls?
  • What is the exact indoor-unit combination?
  • Can the system provide simultaneous heating and cooling?

Do Not Size Rooms From Indoor-Unit Labels

The availability of a 9,000 Btu/h indoor head does not prove a bedroom requires 9,000 Btu/h.

Compare With Several Single-Zone Systems

Separate systems can sometimes provide:

  • Lower minimum capacity
  • Operational redundancy
  • Simpler refrigerant circuits
  • Independent heating and cooling modes

but require more outdoor equipment and installation space.

Buying a Dual-Fuel Heat Pump

A dual-fuel system combines a heat pump with a gas furnace.

It Can Be Useful When:

  • A furnace backup is preferred.
  • Electrical capacity limits a large resistance heat kit.
  • The homeowner wants a staged electrification approach.
  • The local operating-cost strategy favours fuel switching at certain conditions.

Verify Furnace Compatibility

Check:

  • Furnace condition
  • Blower capability
  • Indoor coil match
  • Controls
  • Duct airflow

Define the Changeover Logic

The proposal should explain:

  • When the heat pump operates
  • When the furnace operates
  • How outdoor temperature is measured
  • Whether settings can be adjusted

Test Both Systems During Commissioning

A dual-fuel installation is incomplete until both heating sources and their control transition are verified.

Buying a Full-Electric Heat Pump System

Review Peak Heating Capacity

Compare the heat pump and supplementary electric heat with the building’s design load.

Review Electrical Demand

The resistance heat kit can create a larger peak load than the heat-pump compressor.

Ask How AUX Heat Will Be Controlled

Unnecessary resistance operation can increase electricity consumption.

Check Emergency Heating

Understand what happens if:

  • The outdoor unit faults
  • The compressor is unavailable
  • The thermostat enters Emergency Heat

Do Not Assume Full Electric Requires a Universal Service Size

The home needs an actual electrical load assessment.

Buying a Heat Pump for a Condo or Townhouse

Start With Property Approval

Before ordering equipment, confirm requirements for:

  • Strata approval
  • Outdoor-unit location
  • Exterior penetrations
  • Sound
  • Vibration
  • Condensate drainage
  • Electrical ownership

Small Spaces Need Careful Minimum-Capacity Review

An oversized ductless system can cycle even if it has a variable-speed compressor.

Balcony Installation Needs Complete Planning

Review:

  • Airflow
  • Mounting
  • Defrost water
  • Neighbour exposure
  • Service access

Do Not Begin Work Before Required Written Approval and Program Pre-Approval

Property and incentive requirements are separate and may both apply.

Buying a Heat Pump for an Older Home

Do Not Judge Suitability From Construction Year Alone

Evaluate the home’s current:

  • Insulation
  • Air leakage
  • Windows
  • Ductwork
  • Electrical system
  • Renovations

Coordinate Planned Envelope Improvements

Confirmed insulation and air-sealing work can reduce:

  • Heating load
  • Required heat-pump capacity
  • Supplementary heat
  • Peak electrical demand

Check for Hazardous Materials

Older buildings can contain materials requiring professional assessment before:

  • Drilling
  • Cutting
  • Duct modification
  • Mechanical-room demolition

Review Additions and Suites Separately

Different parts of an older home can have different construction and comfort requirements.

How Important Is the Heat Pump Brand?

Brand matters, but it is only one part of the decision.

Useful Brand Considerations Include:

  • Cold-weather performance
  • Product range
  • Warranty
  • Local parts availability
  • Contractor familiarity
  • Service documentation
  • Control options

Installation Quality Often Matters More Than Brand Tier

A properly selected and commissioned mid-range system can provide better comfort than premium equipment that is:

  • Oversized
  • Connected to restrictive ducts
  • Poorly located
  • Incorrectly configured

Do Not Select From Brand Reputation Alone

Compare the exact model’s:

  • Capacity curve
  • Minimum output
  • Efficiency
  • Sound
  • Controls
  • Matched indoor equipment

Service Support Is Local

The practical value of a warranty depends partly on whether qualified local service and parts are available.

How Should Rebates Affect Your Heat Pump Decision?

Current incentive programs can reduce eligible project costs, but they should not replace proper system design.

Program Requirements Can Include:

  • Existing heating source
  • Property type
  • Household income
  • Contractor requirements
  • Equipment eligibility
  • Heat-load documentation
  • Pre-registration or pre-approval
  • Permit compliance
  • Invoice timing

Check Eligibility Before Installation

Do not assume an application can be completed afterward.

Confirm the Exact Equipment Combination

A manufacturer or product family appearing on an eligible list does not necessarily make every indoor and outdoor combination eligible.

Do Not Select Inferior Design Solely to Capture a Rebate

The equipment still needs to match:

  • The home load
  • Room distribution
  • Ductwork
  • Electrical capacity
  • Long-term comfort goals

Treat the Rebate as Conditional Until Approved

Do not subtract an assumed incentive from the project budget until current program requirements have been checked for the actual application.

Look for correct sizing, cold-weather capacity, suitable minimum output, effective room distribution, compatible ducts, an electrical plan, supplementary heating, exact model numbers, commissioning and clear warranty terms.

What is the best heat pump for a BC home?

There is no universal best model. The appropriate system depends on the home’s load, layout, ducts, electrical capacity, climate, budget and comfort goals.

Should I choose the brand first?

No. Start with the home requirements and system design, then compare suitable models and manufacturers.

Is the most expensive heat pump always the best?

No. Higher cost does not guarantee correct sizing, better distribution or better installation.

Is the highest-efficiency heat pump always best?

No. Capacity, modulation, installation quality, ducts, service support and total project value also matter.

Should I get more than one quote?

Comparing several detailed quotes can help identify differences in system design, equipment, electrical work, warranties and exclusions.

How many heat pump quotes should I get?

There is no mandatory number. Obtain enough detailed proposals to understand the available designs and identify unexplained differences.

Why are heat pump quotes so different?

Quotes can differ in equipment, sizing, ductwork, electrical work, backup heat, permits, controls, commissioning and warranty coverage.

Should I choose the lowest heat pump quote?

Only after confirming that its equipment and installation scope are genuinely comparable with the other proposals.

What should appear on a heat pump quote?

The quote should identify exact models, installation locations, duct or zone work, electrical scope, backup heat, permits, controls, commissioning, warranty and exclusions.

Should the quote include model numbers?

Yes. Brand and product-family names are not sufficiently specific.

What is a heat-load calculation?

It estimates how much heating capacity the home requires under defined indoor and outdoor design conditions.

Why is a heat-load calculation important?

It provides the basis for selecting equipment capacity and supplementary heating.

Can square footage determine heat pump size?

No. Insulation, windows, air leakage, construction and climate substantially affect load.

Can I use my furnace size to select a heat pump?

No. Existing furnace capacity does not prove the home requires that amount of heat.

What is CSA F280?

It is a Canadian standard used for determining residential space-heating and cooling requirements.

Should I receive a copy of the load calculation?

Request the report or summary, including the resulting load and major assumptions.

What is room-by-room heat loss?

It estimates the heating requirement of individual rooms rather than only the whole building.

Why does room-level load matter for ductless systems?

It helps prevent oversized indoor units and identifies which rooms require direct conditioning or supplementary heating.

What is nominal heat pump tonnage?

It is a general capacity classification commonly associated with cooling output, where one nominal ton corresponds to 12,000 Btu/h.

Does nominal tonnage show winter heating capacity?

No. Heating output changes with outdoor temperature.

What cold-weather capacity should I ask for?

Ask for published capacity at temperatures relevant to the home’s local design conditions and compare it with the calculated building load.

Does a cold-climate heat pump work below freezing?

Yes. Cold-climate air-source heat pumps are designed to operate below freezing, but output and efficiency still vary by model and temperature.

Does cold-climate certification mean no backup heat is needed?

No. Supplementary-heating requirements depend on equipment capacity, home load and system-design objectives.

What is a balance point?

It is an outdoor condition where the heat pump’s available heating capacity approximately matches the home’s heating requirement.

What is minimum heat pump capacity?

It is the lowest heating or cooling output a modulating system can provide under specified conditions.

Why is minimum capacity important?

A lower suitable minimum can help the heat pump operate steadily during mild weather without excessive cycling.

Can a variable-speed heat pump still be oversized?

Yes. Variable-speed equipment still has a minimum operating capacity.

What is HSPF2?

HSPF2 is a standardized seasonal heating-efficiency rating.

Should I compare HSPF2 Region IV and Region V?

Not directly. They use different seasonal climate assumptions.

Which HSPF2 region is useful in Canada?

Natural Resources Canada currently identifies HSPF2 Region V as a useful winter-efficiency comparison for Canadian consumers.

What is SEER2?

SEER2 measures standardized seasonal cooling efficiency.

What is COP?

COP is the ratio of useful heating output to electrical input at a specific operating condition.

Is efficiency the same as capacity?

No. Efficiency describes output relative to energy input. Capacity describes how much heat the equipment can deliver.

What is an AHRI reference number?

It identifies a certified combination of applicable indoor and outdoor HVAC components.

Can the same outdoor unit have several AHRI references?

Yes. Different indoor-equipment combinations can produce different certified matches and ratings.

Should the AHRI reference be included in my quote?

It is useful when certified performance or current program eligibility depends on the exact equipment combination.

Should I buy ducted or ductless?

Choose based on existing ducts, room layout, desired coverage, installation access, aesthetics and room-level loads.

Are ductless heat pumps more efficient?

They can avoid central duct losses, but real household performance still depends on room coverage, sizing and operation.

Can one mini-split heat an entire house?

Sometimes in a small open layout. Closed rooms and multiple floors require deliberate distribution planning.

Can one indoor head heat closed bedrooms?

Not reliably. Closed doors restrict air transfer.

Should every bedroom have a ductless head?

Not necessarily. Concealed ducting, central systems or retained supplementary heating can also serve bedrooms.

Is multi-zone better than several single-zone heat pumps?

Neither is universally better. Compare minimum capacity, redundancy, outdoor space, piping complexity and zone behaviour.

Can a multi-zone system heat one room and cool another?

Many conventional residential multi-zone systems cannot provide simultaneous heating and cooling. Verify the exact equipment.

Can I reuse my furnace ducts?

Possibly, after evaluating airflow, return capacity, static pressure, leakage and room distribution.

Should static pressure be measured?

It is an important measurement for assessing existing duct capacity and commissioning many central systems.

Can a new heat pump fix bad ducts?

No. Duct restrictions, leakage and distribution problems need separate correction.

Do heat pumps require more airflow than furnaces?

Heat pumps can require different and sometimes higher airflow than existing furnace operation, depending on equipment and design.

Why does heat-pump air feel cooler than furnace air?

Heat pumps commonly deliver lower supply-air temperatures over longer cycles than gas furnaces.

Do I need electric backup heat?

That depends on the heat pump’s capacity, home load, climate and selected system strategy.

How large should the electric heat kit be?

It should be selected from the calculated load, heat-pump capacity and intended backup strategy rather than using a universal size.

Can electric backup increase my bill?

Yes. Resistance heat generally uses more electricity than normal compressor heating for the same useful output.

What is a dual-fuel heat pump?

It combines an electric heat pump with a fuel-fired furnace.

Should I keep my existing furnace?

Possibly, if it is in good condition, compatible with the proposed heat pump and suitable for the project goals.

Can any furnace work with any heat pump?

No. Coil, blower, control and certified-system compatibility need to be checked.

Does a heat pump require 200-amp electrical service?

No. Electrical capacity must be calculated for the actual home and proposed system.

Can a heat pump work with 100-amp service?

In some homes, yes. A qualified electrical contractor must assess the available capacity.

What is a meter-data load calculation?

It uses historical electrical-demand data to help evaluate the home’s existing maximum demand and remaining service capacity.

Can load management avoid an electrical-service upgrade?

Sometimes, depending on the existing loads, proposed equipment and applicable electrical requirements.

Where should the outdoor unit go?

It needs suitable airflow, service clearance, mounting, sound control, physical protection and defrost-water drainage.

Can the outdoor unit go under a deck?

Possibly, if all airflow, clearance, drainage and service requirements are satisfied.

Can I hide the outdoor unit in an enclosure?

Only if the enclosure preserves all required intake and discharge airflow. Tight decorative enclosures can harm performance.

Does outdoor-unit sound matter?

Yes. Review the exact model’s published sound information and the proposed location relative to occupied spaces and neighbours.

Does a heat pump create water outside?

Yes. During winter defrost, water can drain from the outdoor coil.

Does a ductless heat pump require a drain?

Yes. The indoor unit produces condensate while cooling.

Is gravity drainage better than a condensate pump?

A reliable gravity drain avoids another mechanical component where the building layout permits it.

Can a condensate pump fail?

Yes. It should remain accessible for service and may require appropriate overflow protection.

Does a heat pump need an electrical permit in BC?

In most residential installations or upgrades, regulated electrical work and an electrical permit are required.

Does removing a gas furnace require a gas permit?

Applicable regulated gas work and permitting must be addressed when gas equipment is modified, removed or deactivated.

Do condos need strata approval?

Usually when the installation affects the exterior, common property, limited common property or building systems governed by the strata.

Does a government permit replace strata approval?

No. They are separate requirements.

Can I order equipment before strata approval?

Avoid ordering non-returnable equipment before the design and location are approved.

Should I choose a contractor based on rebate status?

Program eligibility can require specific contractor qualifications, but the contractor should also demonstrate suitable design, installation and service capabilities.

Can rebate requirements change?

Yes. Verify current rules before signing the final contract or beginning work.

Does an eligible heat pump guarantee a rebate?

No. Homeowner, property, contractor, installation, permit and application requirements can also apply.

Should I buy a heat pump only because it qualifies for a rebate?

No. It still needs to be suitable for the home and project objectives.

What is heat pump commissioning?

It is the process of configuring and verifying the installed system’s operation and performance.

Is turning the heat pump on the same as commissioning?

No. Commissioning can include controls, airflow, backup heat, drainage and refrigeration-system verification.

Should airflow be checked after installation?

Yes for ducted systems. Blower configuration and duct performance should be verified.

Should every ductless head be tested?

Yes. Each indoor unit should be checked for operation, airflow, controls, communication and drainage.

Should backup heat be tested?

Yes when the system includes supplementary heating.

What warranty should a heat pump have?

Terms vary by manufacturer and contractor. Compare parts, compressor and labour coverage for the exact system.

Does a parts warranty include labour?

Not necessarily.

Does a parts warranty include refrigerant?

Not necessarily.

Does warranty registration matter?

It can affect coverage depending on the manufacturer’s current terms.

Should I consider parts availability?

Yes. Local access to controls, motors, boards and other proprietary components affects future service.

How much should a heat pump cost?

Total cost depends on system type, capacity, number of zones, ducts, electrical work, backup heat, permits and installation complexity.

Can a heat pump lower my energy bills?

Potentially, particularly when replacing electric resistance, oil, propane or inefficient equipment. Actual savings depend on the home, rates and operating strategy.

Does a higher HSPF2 guarantee lower bills?

No. Home heat loss, weather, sizing, ducts, thermostat use and supplementary heat also affect consumption.

Should I replace insulation before buying a heat pump?

Confirmed envelope improvements should be coordinated with system sizing, but every home does not require a complete insulation retrofit first.

Should I wait until my furnace fails?

Planning before an emergency provides more time for load calculations, contractor comparison, electrical work, permits and approvals.

Can I buy a heat pump online and hire someone to install it?

This can create equipment-matching, warranty, permit, qualification and service-support problems. Confirm the complete arrangement before purchasing equipment.

Can I install a heat pump myself?

Regulated electrical and applicable refrigeration work must meet BC qualification, contractor and permit requirements. DIY installation can also affect warranty and incentive eligibility.

Does Bernoulli provide free heat pump estimates?

Yes. New heat pump installation and replacement estimates are currently free.

What areas does Bernoulli serve?

Bernoulli Heating and Cooling serves Metro Vancouver and Fraser Valley.

How much does Bernoulli charge to diagnose an existing heat pump?

The current diagnostic appointment charge is $135. Repair labour, parts, refrigerant and additional materials are separate.
