Updated July 27, 2026: Heat pump permit, rebate, contractor and equipment requirements can change. Confirm current requirements with the applicable municipality, Technical Safety BC and the relevant rebate program before equipment is ordered or installation begins.
The heat pump installation process should begin with an onsite home assessment and finish with testing, commissioning and homeowner instruction. Correct installation involves much more than selecting an outdoor unit and connecting refrigerant piping.
A complete process may include a heat-load calculation, equipment selection using low-temperature performance data, duct and airflow evaluation, indoor and outdoor equipment placement, electrical planning, permit review, condensate and defrost-water planning, installation, functional testing and final documentation.
The details vary between central ducted, ductless, multi-zone, full-electric and dual-fuel systems. Existing homes also create challenges that are not visible from a product brochure, including restricted ductwork, limited electrical capacity, finished walls, strata requirements and unsuitable outdoor-unit locations.
This guide explains the main installation steps and the questions BC homeowners should ask before approving a heat pump proposal.
What Happens During a Heat Pump Installation?
A professional heat pump installation normally follows four broad phases:
- Assessment and design: Determine the home’s heating and cooling needs, existing equipment, ductwork, electrical conditions and suitable equipment locations.
- Planning and approvals: Select equipment, prepare the scope of work, confirm permits, obtain property or strata approvals and review rebate requirements.
- Installation: Install the indoor and outdoor equipment, refrigerant piping, condensate drainage, electrical components, controls and any required ductwork.
- Commissioning and handover: Test airflow, controls, refrigerant operation, backup heat and system performance before explaining operation and maintenance to the homeowner.
Why the Process Matters
Two homes can receive the same heat pump model and achieve very different results because installation conditions differ.
Performance can be affected by:
- Equipment sizing
- Low-temperature heating capacity
- Duct airflow
- Refrigerant commissioning
- Outdoor-unit location
- Backup heating controls
- Building heat loss
ENERGY STAR identifies correct sizing, adequate airflow, evaluated ductwork and correct refrigerant charge as essential parts of quality HVAC installation.
What Should Happen Before a Heat Pump Quote Is Finalized?
A contractor needs enough information to design the job before providing a reliable final proposal.
An Onsite Review May Include:
- Current heating and cooling equipment
- Home size and layout
- Number of floors
- Insulation and window conditions
- Mechanical-room access
- Existing supply and return ducts
- Electrical panel and available space
- Possible outdoor-unit locations
- Possible refrigerant-line routes
- Condensate drainage
- Backup heating requirements
Photos and Floor Plans Help, but They Are Not Always Enough
Remote information can support an initial discussion, but it may not reveal:
- Restricted return-air systems
- Hidden duct damage
- Electrical limitations
- Finished-wall routing problems
- Outdoor clearance concerns
- Strata restrictions
A Quote Should Match the Actual Installation
A low price based on assumptions can become an expensive collection of change orders once the work begins.
The proposal should clearly identify what is included, what remains subject to inspection and which work is excluded.
Step 1: Complete a Home and Site Assessment
The first installation step is understanding the home, not selecting a brand.
Assess the Existing Heating System
The contractor should identify whether the home currently uses:
- Natural gas furnace
- Electric furnace
- Electric baseboards
- Boiler
- Existing heat pump
- Multiple heating systems
Understand the Homeowner’s Goal
Possible objectives include:
- Full-electric heating and cooling
- Adding cooling to a furnace
- Dual-fuel operation
- Replacing electric baseboards
- Improving upstairs comfort
- Conditioning an addition
- Creating room-by-room zoning
Inspect the Building
Important building characteristics include:
- Insulation levels
- Window type and area
- Air leakage
- Ceiling height
- Basement and crawl-space conditions
- Solar exposure
- Number and use of rooms
Identify Access Limitations
Existing homes may require routing through:
- Closets
- Attics
- Crawl spaces
- Finished ceilings
- Exterior line covers
The homeowner should understand which surfaces may need to be opened and who is responsible for final drywall, paint, carpentry or exterior finishing.
Step 2: Calculate the Home’s Heating and Cooling Load
Heat pump size should be based on how much heating and cooling the home requires, not only its floor area or the capacity of the old furnace.
What Is a Heat-Load Calculation?
A heat-load calculation estimates how much heat the building loses under winter design conditions.
It considers factors such as:
- Outdoor design temperature
- Indoor design temperature
- Wall and ceiling insulation
- Windows and doors
- Air leakage
- Floor and foundation conditions
- Building dimensions
Cooling Load Is Also Important
Cooling calculations consider:
- Outdoor summer conditions
- Window orientation
- Solar gain
- Occupancy
- Lighting and appliance heat
- Building insulation
CSA F280 and Other Recognized Methods
Better Homes BC recommends heat-load calculations for all heat pump installations and identifies CAN/CSA F280 methods among the accepted approaches for applicable rebate documentation.
Review the official Better Homes BC heat-load calculation guidance.
Why Copying the Old Furnace Size Can Be Wrong
Older furnaces were frequently selected with excess capacity.
A furnace rated at 80,000 BTU/h does not prove the home requires an 80,000 BTU/h heat pump.
The old equipment may also have been selected before:
- Insulation upgrades
- New windows
- Air sealing
- Home additions
- Layout changes
Low-Temperature Capacity Must Be Considered
The contractor should compare the calculated heating load with the heat pump’s published capacity at relevant outdoor temperatures.
A nominal three-ton label does not describe the system’s complete winter performance.
Natural Resources Canada provides a sizing and selection toolkit developed for Canadian climates and residential retrofit applications.
Review the official NRCan air-source heat pump sizing and selection toolkit.
Step 3: Select the Heat Pump Type and Capacity
Once the building load and installation conditions are understood, the contractor can select an appropriate system type.
Central Ducted Heat Pump
A central system can use existing or modified ductwork to serve multiple rooms.
It may be suitable when:
- The home already has usable ducts
- Whole-home conditioning is required
- A furnace will remain as dual-fuel backup
- The homeowner prefers fewer visible indoor units
Ductless Mini-Split
A single-zone ductless system serves a defined area using one outdoor unit and one indoor head.
It may suit:
- Open living spaces
- Additions
- Homes without ducts
- Targeted comfort problems
Ductless Multi-Zone System
A multi-zone outdoor unit serves multiple indoor units.
Selection should consider:
- Total connected capacity
- Individual room loads
- Outdoor-unit minimum output
- Simultaneous zone use
- Mode compatibility
Full-Electric Heat Pump
The system and any supplemental electric heat should be designed to meet the home’s winter heating requirements under the intended strategy.
Dual-Fuel Heat Pump
A dual-fuel installation combines a heat pump with a gas furnace.
The design must coordinate:
- Heat pump operation
- Furnace operation
- Outdoor-temperature changeover
- Thermostat controls
- Indoor blower operation
Do Not Select Equipment From Efficiency Ratings Alone
SEER2, HSPF2 and COP information is useful, but the equipment must also provide suitable:
- Heating capacity
- Cooling capacity
- Minimum modulation
- Sound performance
- Airflow capability
- Controls
- Warranty support
Step 4: Evaluate Ductwork, Airflow and Zoning
This step is essential for central heat pumps.
Existing furnace ducts should not automatically be assumed suitable for a new heat pump.
The Contractor Should Review:
- Supply trunk capacity
- Return-air capacity
- Branch duct sizes
- Flexible duct condition
- Register and grille sizes
- Filter arrangement
- Duct leakage
- Attic and crawl-space insulation
Why Heat Pump Airflow Can Be Different
A heat pump may require a different airflow strategy from the old furnace.
Insufficient duct capacity can create:
- High static pressure
- Loud airflow
- Poor room comfort
- Reduced equipment capacity
- Coil problems
- Shortened component life
Return Air Is Frequently Overlooked
A large supply system cannot move its designed airflow if the return side is too restrictive.
The review should include:
- Return duct dimensions
- Filter pressure drop
- Return grille area
- Closed doors and room-air pathways
Zoning Requires Design
A zoned duct system must maintain acceptable airflow when only one or two zones are active.
Closing dampers without considering minimum equipment airflow can create noise, high pressure and cycling problems.
Quality Installation Guidance
ENERGY STAR states that poor airflow can reduce efficiency, increase utility costs, reduce comfort and shorten equipment life. It recommends evaluating ducts and setting airflow to manufacturer requirements.
Review the official ENERGY STAR HVAC quality installation guidance.
Step 5: Plan Indoor and Outdoor Equipment Locations
Equipment location affects performance, sound, drainage, appearance and serviceability.
Outdoor-Unit Location Should Consider:
- Manufacturer clearances
- Unrestricted airflow
- Service access
- Bedroom and neighbouring windows
- Property boundaries
- Snow and ice
- Defrost-water drainage
- Roof runoff
- Foundation location
- Refrigerant-line length
Ground Pad or Wall Bracket?
The appropriate mounting method depends on:
- Site drainage
- Expected snow and ice
- Wall construction
- Vibration transmission
- Available space
- Manufacturer requirements
Sound-Sensitive Locations
A quiet outdoor unit can still become disruptive when placed directly below a bedroom window or mounted to a wall that transfers vibration into framing.
Sound planning should consider both published equipment sound data and the physical installation.
Indoor Ductless-Unit Location
A ductless head should be positioned to support:
- Room air circulation
- Condensate drainage
- Filter access
- Blower cleaning
- Refrigerant-line routing
- Future service access
Do Not Hide Equipment So Well That It Cannot Be Serviced
Indoor and outdoor components require access for filters, coils, drain pans, electrical testing and future repair.
Step 6: Review Electrical Work, Permits and Property Approvals
Electrical and permit planning should happen before installation day.
Electrical Review
The project may require review of:
- Electrical panel capacity
- Available breaker spaces
- Dedicated circuits
- Outdoor disconnect
- Indoor equipment power
- Auxiliary electric heating
- Existing electrical service
Do Not Promise a Panel Upgrade Without Checking
Some homes require electrical modifications, while others can accommodate the heat pump without replacing the main panel.
The answer depends on the equipment and the existing electrical system.
Electrical Permits
Technical Safety BC states that residential heat pumps are regulated electrical equipment and that, in most cases, an electrical permit and appropriately licensed electrical contractor are required for installation or upgrade work.
The authority issuing the permit may be Technical Safety BC or the applicable municipality.
Gas Permits
If the project modifies or removes a natural gas furnace or boiler, gas-permit requirements also need to be addressed.
Refrigeration Requirements
Additional refrigeration regulatory requirements may apply in certain larger residential, multi-unit or refrigerant-specific installations.
The contractor should confirm which rules apply to the actual equipment and building.
Review the official Technical Safety BC heat pump permit guidance.
Municipal and Building Requirements
Depending on the project and municipality, other requirements may relate to:
- Outdoor-unit location
- Property setbacks
- Noise
- Building penetrations
- Structural mounting
Strata Approval
Condo and townhouse owners should review strata bylaws and obtain required written approval before equipment is ordered.
The application may need to show:
- Outdoor-unit location
- Equipment dimensions
- Sound information
- Line-set route
- Drainage plan
- Electrical work
- Exterior appearance
Step 7: Finalize a Detailed Written Proposal
The written proposal should describe the complete project rather than listing only the outdoor-unit model and total price.
Equipment Information
The quote should identify:
- Outdoor-unit model
- Indoor-unit or coil model
- Air-handler or furnace details
- Thermostat or controller
- System capacity
- Warranty information
Installation Scope
The scope should address:
- Removal of existing equipment
- Equipment mounting

The proposal should explain:
- Which program is being considered
- Who confirms eligibility
- Who submits documentation
- Whether the contractor must be program registered
- Whether the equipment combination must appear on a qualifying list
Do Not Rely on a Verbal Scope
Written details protect both the homeowner and contractor when the project includes several trades or building modifications.
Step 8: Complete the Heat Pump Installation
The physical installation varies by system, but several major components are common.
Outdoor Equipment
The outdoor unit is installed on its designed mounting system with appropriate:
- Clearances
- Stability
- Drainage
- Airflow
- Service access
Indoor Equipment
The indoor portion may include:

Removal of Existing Equipment
The scope should define whether the old equipment, refrigerant, gas components, venting and related materials are being removed, retained or modified.
Step 9: Test and Commission the Heat Pump
Installation is not finished when the equipment powers on.
Commissioning confirms that the installed system operates as intended.
Refrigerant-Side Commissioning
Depending on the equipment and installation, this may include:
- Testing completed refrigerant connections
- Evacuating the installed piping according to applicable procedures
- Confirming refrigerant charge using manufacturer instructions
- Checking operating temperatures and pressures
- Reviewing equipment fault information
Airflow Commissioning
For ducted systems, commissioning may include:
- Blower setup
- Total external static pressure
- Supply airflow
- Return-air performance
- Register airflow
- Room balancing
Functional Testing
The contractor should test applicable operating modes, including:
- Heating
- Cooling
- Indoor fan
- Thermostat control
- Auxiliary heat
- Emergency Heat
- Dual-fuel changeover
- Condensate drainage
Defrost and Cold-Weather Setup
Not every aspect of cold-weather operation can be observed on a warm installation day, but the contractor should confirm that sensors, backup-heating logic and relevant configuration match the equipment design.
Why Measurements Matter
A system can start and still have:
- Incorrect airflow
- Excessive static pressure
- Incorrect refrigerant charge
- Improper thermostat configuration
- Backup heat that does not operate
ENERGY STAR quality-installation guidance emphasizes verifying airflow, refrigerant charge and duct performance rather than judging success only by whether the equipment turns on.
Step 10: Complete the Homeowner Handover
The homeowner should understand how to operate and maintain the new system before the contractor leaves.
Thermostat and Controls
The contractor should explain:
- Heat and Cool modes
- Fan Auto, On and Circulate
- Recommended temperature settings
- Auxiliary heat indicators
- Emergency Heat where applicable
- Ductless remote controls
- Basic fault-code reporting
Filter and Maintenance Information
The homeowner should know:

- Final invoice
- Rebate documents
- Commissioning information
Confirm the Scope Is Complete
The homeowner and contractor should review:
- Equipment operation
- Visible workmanship
- Drainage
- Line-cover installation
- Outstanding finishing work
- Any remaining inspection or permit steps
How Long Does Heat Pump Installation Take?
There is no universal installation time.
Project duration depends on:
- System type
- Number of indoor units
- Duct modifications
- Electrical work
- Equipment access
- Wall and ceiling penetrations
- Removal of old equipment
- Permit and inspection scheduling
Projects That May Be Simpler
A straightforward single-zone ductless installation with accessible routing may require less onsite work than a whole-home central retrofit.
Projects That May Take Longer
- Major duct replacement
- Electrical service changes
- Multiple ductless zones
- Attic installation
- Dual-fuel integration
- Strata coordination
- Gas-equipment removal
Do Not Judge Quality by Speed Alone
A rushed installation that skips airflow measurement, commissioning or proper drainage is not a bargain. It is merely a future service call wearing new equipment.
How Should Homeowners Prepare for Installation Day?
- Clear access to the mechanical room.
- Clear the planned outdoor-unit location.
- Move furniture away from indoor work areas.
- Protect valuable or fragile belongings.
- Arrange access to the electrical panel.
- Confirm parking and equipment access.
- Notify the contractor about pets, alarms and locked areas.
- Confirm whether water, electricity or heating will be interrupted.
- Review who handles drywall, painting and carpentry.
- Confirm strata or property approvals are complete.
Should the Homeowner Be Present?
It is useful for an authorized adult to be available at the beginning and end of the project to confirm access, answer building questions and receive the system handover.
Will the Home Lose Heating or Cooling?
Temporary interruption is normal when existing equipment is removed or controls are changed.
The contractor should explain the expected interruption before work begins, particularly during extreme weather.
What Is Different About a Central Ducted Heat Pump Installation?
A central installation depends heavily on the duct system and indoor blower arrangement.
Existing Furnace With Heat Pump
The project may retain the furnace and add:
- Matched indoor coil
- Outdoor heat pump
- Heat-pump thermostat or control
- Dual-fuel changeover strategy
New Air Handler
A full-electric project may replace the existing furnace with an air handler and, where designed, electric supplemental heat.
Important Central-System Measurements
- Static pressure
- Supply airflow
- Return airflow
- Temperature performance
- Backup-heating operation
Existing Ducts May Need Modification
Possible work includes:
- Larger return duct
- New supply trunk
- Additional branch ducts
- Register replacement
- Duct sealing
- Attic duct insulation
- Balancing dampers
What Is Different About Ductless Heat Pump Installation?
Ductless systems avoid central ductwork but still require careful room-by-room design.
Indoor-Unit Selection
Each zone should be selected using its own:
- Heating load
- Cooling load
- Room layout
- Air-distribution needs
- Occupancy
Indoor-Unit Placement
The indoor unit should not be selected only because one wall is easiest to drill.
Placement affects:
- Comfort
- Noise
- Condensate drainage
- Filter access
- Appearance
Multi-Zone Outdoor Units
The designer should consider both the total connected load and operation when only one or two small zones require conditioning.
Condensate Pumps
Gravity drainage is preferable where practical, but some locations require a condensate pump.
The homeowner should understand that pumps add maintenance and can create noise or service requirements.
What Is Different About Dual-Fuel Heat Pump Installation?
A dual-fuel installation requires coordination between the electric heat pump and gas furnace.
Equipment Compatibility
The contractor should verify that the selected:
- Outdoor unit
- Indoor coil
- Furnace
- Blower
- Thermostat or control
can operate together as designed.
Changeover Strategy
The system needs a defined method for determining when the heat pump operates and when the furnace provides heating.
This may consider:
- Outdoor temperature
- Heat-pump capacity
- Home heating load
- Utility-cost objectives
- Comfort requirements
Gas Work
Any furnace, gas piping or venting modifications must follow the applicable gas-permit and qualified-trade requirements.
Commission Both Heating Sources
Testing should verify:
- Heat pump heating
- Cooling
- Furnace heating
- Changeover controls
- Indoor blower operation
- Thermostat staging
What Should Condo and Strata Owners Check?
Do not order equipment before confirming the strata process.
Strata Review May Address:
- Exterior-wall penetrations
- Outdoor-unit location
- Balcony use
- Roof or common-property access
- Electrical capacity
- Condensate discharge
- Noise
- Appearance
- Contractor insurance
Obtain Written Approval
Verbal approval from a council member or building manager may not satisfy the strata’s formal requirements.
Multi-Unit Permit Requirements Can Differ
The contractor should confirm whether the building size, equipment capacity and refrigerant type create additional regulatory requirements.
Will a Heat Pump Require an Electrical Panel Upgrade?
Sometimes, but not always.
The Review Should Consider:
- Existing service rating
- Current household loads
- Available panel spaces
- Heat pump electrical requirements
- Air-handler requirements
- Electric auxiliary heating
- Other planned electric upgrades
Full-Electric Systems Can Have Larger Backup Loads
Electric resistance backup may require significant electrical capacity compared with the compressor heat pump alone.
Dual-Fuel May Have Different Requirements
Retaining a gas furnace as backup can change the electrical design, but the outdoor heat pump still requires a compliant electrical supply.
Get the Electrical Scope in Writing
The proposal should state whether:
- Electrical work is included
- A panel upgrade is included
- An electrical contractor will quote separately
- The price is subject to further electrical inspection
Which Permits May Be Required for a Heat Pump in BC?
The exact permit path depends on the property, equipment and work being completed.
Electrical Permit
Technical Safety BC states that most residential heat pump installations or upgrades require an electrical permit and regulated electrical work.
Gas Permit
A gas permit may be required when a natural gas furnace or boiler is modified or removed.
Refrigeration Permit
Certain applications involving larger residential buildings, equipment capacity or specific refrigerants may be regulated as refrigeration equipment.
Local Jurisdiction
Some municipalities issue their own permits rather than Technical Safety BC.
The contractor should confirm the Authority Having Jurisdiction before work begins.
Ask These Questions
- Which permits apply?
- Who obtains each permit?
- Are permit fees included?
- Will an inspection be required?
- Who provides the final permit documentation?
When Should Heat Pump Rebate Eligibility Be Checked?
Before the equipment is ordered and before installation begins.
Rebate programs can have requirements affecting:
- Existing heating fuel
- Home type
- Household income
- Contractor registration
- Eligible equipment combinations
- Heat-load calculations
- Backup heating
- Permit documentation
- Application deadlines
Do Not Assume an Efficient Heat Pump Automatically Qualifies
An efficient model may still be ineligible if:
- The contractor is not registered for the applicable program
- The equipment combination is not on the required list
- The home or existing heating system does not meet program conditions
- Required documentation was not completed
Current Program Requirements
Better Homes BC currently requires program-specific contractor, installation, equipment and documentation conditions for applicable heat pump incentives.
Review the current Home Renovation Rebate Program requirements and Energy Savings Program requirements before relying on rebate eligibility.
Keep All Documentation
Retain:
- Final paid invoice

Heat Pump Installation Warning Signs
No Onsite Assessment
A final whole-home proposal based only on square footage and a photograph may overlook major duct, electrical and access issues.
No Load or Capacity Discussion
The contractor should be able to explain how the system capacity was selected.
The New System Simply Matches the Old Furnace Rating
Old equipment size is not a substitute for current building-load analysis.
Ductwork Is Never Mentioned
A central heat pump cannot perform correctly when the duct system cannot move the required air.
Permit Responsibility Is Unclear
The quote should not leave homeowners discovering permit requirements after the installation.
Rebate Is Guaranteed Without Eligibility Review
Program eligibility depends on current rules, equipment, contractor status and documentation.
No Commissioning Details
“We turn it on and see if it works” is not a commissioning procedure. It is optimism with tools.
Large Cash Deposit Without Clear Contract Terms
The proposal should identify payment stages, equipment, scope, cancellation terms and responsibilities.
Outdoor Location Is Selected Only for Installer Convenience
Airflow, sound, drainage, service access and property conditions should also be considered.
What Should Homeowners Watch After Installation?
During the First Day
Check:
- Heating and cooling response

Heat Pump Installation Process: Frequently Asked Questions
What is the first step in installing a heat pump?
The process should begin with an onsite assessment of the home, current HVAC equipment, building load, ductwork, electrical system and suitable equipment locations.
Do I need a heat-load calculation?
A heat-load calculation is recommended for proper heat pump sizing and is required for certain BC rebate applications and system types.
Can a heat pump be sized using square footage?
Square footage alone is not enough. Windows, insulation, air leakage, orientation, climate and building shape also affect heating and cooling loads.
Should the new heat pump match my old furnace BTU rating?
Not automatically. The old furnace may be oversized, and furnace input or output capacity does not directly establish the correct heat pump capacity.
What does a heat pump load calculation include?
It considers building dimensions, insulation, windows, doors, air leakage and indoor and outdoor design temperatures to estimate the required capacity.
Can a heat pump be too large?
Yes. Oversized equipment can cycle frequently, reduce comfort and provide weaker summer humidity control.
Can a heat pump be too small?
Yes. An undersized system may struggle during peak conditions and rely more heavily on backup heat.
How do I choose between ducted and ductless?
The choice depends on existing ductwork, home layout, zoning goals, appearance, installation access and whole-home comfort requirements.
Can I use my existing furnace ducts?
Possibly, but they should be evaluated for airflow, static pressure, leakage, insulation and room distribution before the heat pump is selected.
Why might my return duct need to be enlarged?
The existing return system may not provide enough airflow for the selected heat pump and indoor blower.
Should duct static pressure be measured?
For ducted systems, static-pressure measurement helps determine whether the blower and duct system are operating within acceptable conditions.
Will I need new supply registers?
Possibly. Existing registers may be too small, noisy or unsuitable for the required airflow.
Where should the outdoor heat pump be installed?
The location should provide suitable airflow, manufacturer clearances, service access, drainage and reasonable separation from sound-sensitive areas.
Can the outdoor unit be installed below a bedroom window?
It may be physically possible, but sound and vibration should be considered before selecting that location.
Is a wall bracket better than a ground pad?
Neither is always better. The choice depends on drainage, snow, wall construction, vibration, available space and equipment requirements.
Why does outdoor defrost drainage matter?
Winter frost melts during defrost and can refreeze below the unit, near walkways or around the foundation if drainage is not planned.
Can roof water drain onto a heat pump?
The installation should avoid roof runoff that can freeze on the outdoor unit and create icing problems.
Where should a ductless indoor unit be installed?
It should support good room airflow, drainage, service access and a practical refrigerant-line route.
Can a ductless head be installed on any wall?
No. Structure, clearances, drainage, electrical access, line routing and air distribution all affect placement.
Will a heat pump require a new electrical circuit?
Most permanently installed systems require electrical work designed for the selected equipment. The exact requirements depend on the system and existing electrical installation.
Will I need an electrical-panel upgrade?
Not always. A qualified electrical assessment should consider existing service capacity, panel space, heat pump load and supplemental electric heating.
Does a heat pump installation need an electrical permit in BC?
Technical Safety BC states that, in most residential installations or upgrades, an electrical permit is required. The issuing authority may be Technical Safety BC or a municipality.
Who obtains the heat pump permit?
When a licensed contractor completes regulated work, the contractor normally obtains the applicable permit. Responsibility should be stated in the proposal.
Does replacing a gas furnace require a gas permit?
Gas-permit requirements apply when regulated gas equipment or piping is modified or removed. The contractor should confirm the applicable scope.
Does every residential heat pump require a refrigeration permit?
No. Refrigeration regulatory requirements depend on factors such as the building, equipment capacity and refrigerant. The applicable authority should confirm the actual project requirements.
Do I need strata approval?
Condo and townhouse owners commonly need approval for outdoor equipment, exterior penetrations, electrical work, drainage, sound and use of common property.
Should I check rebates before or after installation?
Before installation. Contractor registration, equipment lists, heat-load calculations and documentation requirements may affect eligibility.
Does every heat pump qualify for a rebate?
No. Eligibility depends on the current program, home, existing heating system, contractor and exact equipment combination.
Can I install the heat pump myself and receive a rebate?
Current BC programs commonly require installation by approved or registered contractors for eligible heat pump upgrades. Check the exact program before beginning work.
What should be included in a heat pump quote?
The quote should identify equipment, installation scope, ductwork, electrical work, controls, permits, drainage, commissioning, warranties, exclusions and total price.
Should indoor and outdoor model numbers be listed?
Yes. Complete model information helps confirm equipment matching, efficiency data, warranty and rebate eligibility.
Should the quote include permits?
It should clearly state which permits are included, who obtains them and whether permit fees or inspections are separate.
How long does heat pump installation take?
Duration depends on the system, number of zones, ductwork, electrical work, access and removal of existing equipment. There is no universal installation time.
Will the heating be turned off during installation?
Usually for part of the project. The contractor should explain the expected interruption before work begins.
Will walls or ceilings need to be opened?
They may, particularly for new ducts, concealed refrigerant lines, drains or electrical wiring. The scope should identify who handles final finishing.
Can a heat pump be installed without changing my thermostat?
That depends on thermostat compatibility, system controls, compressor stages, backup heat and whether the equipment uses proprietary communication.
Does a variable-speed heat pump need a special thermostat?
Some variable-capacity systems use manufacturer-specific communicating controls to access their full operation and diagnostic features.
What is heat pump commissioning?
Commissioning is the process of testing and adjusting the installed system to verify controls, airflow, refrigerant operation, drainage and backup heating.
Is turning the heat pump on enough to commission it?
No. A system can turn on while still having incorrect airflow, excessive static pressure, control errors or improper refrigerant conditions.
Should airflow be tested after installation?
Yes for ducted systems. Airflow and static pressure help confirm that the blower and ducts can support the equipment.
Should refrigerant charge be checked?
The installed refrigerant system should be commissioned according to manufacturer instructions, including applicable charge and operating checks.
Should the contractor test both heating and cooling?
Applicable operating modes should be tested where conditions and equipment procedures allow.
Should auxiliary heat be tested?
Yes. Full-electric central systems should have their supplemental heating and thermostat staging verified.
Should a dual-fuel furnace be tested with the heat pump?
Yes. The contractor should confirm heat pump heating, furnace heating and the intended changeover control.
What documents should I receive?
Documentation may include manuals, model and serial numbers, invoices, permits, warranty information, commissioning records and rebate documents.
Who registers the heat pump warranty?
Warranty-registration responsibility should be confirmed with the contractor and completed within the manufacturer’s required period.
What should I check during the first week?
Watch room comfort, thermostat operation, airflow, noise, vibration, condensate drainage, fault codes and outdoor-unit performance.
Why is my new heat pump blowing air that feels cooler than my furnace?
Heat pumps commonly deliver longer periods of moderately warm air rather than short bursts of very hot furnace air.
Why is my new heat pump noisy?
Possible causes include airflow, duct static pressure, equipment location, vibration transfer, loose components or incorrect fan setup.
Why does my new heat pump run for long periods?
Variable-capacity heat pumps may run for long periods at reduced output. Long runtime is not automatically a problem when comfort is maintained.
What if the heat pump cannot keep the home warm?
The installer should review equipment capacity, airflow, refrigerant performance, backup heat, thermostat settings, ductwork and building load.
What if one bedroom is still cold?
The problem may involve branch-duct airflow, balancing, return air, insulation or room heat loss rather than the outdoor heat pump itself.
Should I receive a free heat pump installation estimate?
Bernoulli Heating and Cooling currently provides free estimates for new heat pump installation projects.
