Updated July 29, 2026: Heat pump efficiency requirements, incentive programs and permit requirements can change. Confirm current BC program and regulatory requirements before equipment is ordered or installation begins.
Heat pump vs air conditioner: both systems can cool a home by transferring indoor heat outdoors. The major difference is that an air-source heat pump can reverse the refrigeration cycle and provide heating in winter, while a conventional central air conditioner is designed for cooling only.
For a BC homeowner replacing an aging air conditioner, a heat pump may be worth considering if you also want electric heating, lower dependence on a furnace, dual-fuel operation or the ability to eventually move toward full-electric space heating.
A conventional air conditioner can still be a reasonable choice when the existing heating system is staying long term and the homeowner only needs cooling. The correct decision depends on the furnace or other heating equipment, electrical system, home heating load, ductwork, climate, equipment performance and project budget.
This guide compares heat pumps and air conditioners from the perspective of homeowners in British Columbia, including central ducted, ductless and furnace-based retrofit applications.
Heat Pump or Air Conditioner: Which Should You Choose?
A heat pump is usually worth serious consideration when you need new cooling and also want the equipment to contribute to winter heating.
Consider a Heat Pump When:
- Your existing air conditioner needs replacement.
- You want both heating and cooling from the outdoor equipment.
- You want to reduce furnace runtime.
- You are considering dual-fuel heating.
- You want to replace electric resistance heating.
- You are planning a future full-electric HVAC conversion.
A Conventional Air Conditioner May Still Make Sense When:
- You only need cooling.
- Your existing heating system will remain the sole heating source.
- The building or project has a specific reason to use cooling-only equipment.
- The total installed AC project is more suitable for the homeowner’s objectives.
Do Not Compare Only the Outdoor-Unit Price
The real comparison is:
Cooling-only system + existing or future heating equipment
versus:
Heat pump + required indoor equipment + backup-heating strategy
Looking at one condenser price while ignoring the rest of the HVAC system can produce a very tidy spreadsheet and a very poor decision.
How Are a Heat Pump and Air Conditioner Similar?
In cooling mode, the two technologies are closely related.
Natural Resources Canada explains that an air-source heat pump provides cooling by transferring heat from indoor air to the outdoors, which is fundamentally the same process used by an air conditioner.
Both Commonly Include:
- Compressor
- Outdoor coil
- Outdoor fan
- Indoor refrigeration coil
- Refrigerant piping
- Indoor blower or ductless fan
- Electrical controls
During Cooling
Both systems:
- Absorb heat from indoor air.
- Move that heat through the refrigeration circuit.
- Release the heat outdoors.
- Remove moisture from indoor air as condensate.
The Difference Appears in Heating Mode
A heat pump includes the ability to reverse the refrigeration cycle so the outdoor coil absorbs heat and the indoor coil releases heat into the home.
A conventional air conditioner does not provide this winter heat-pump mode.
For additional background, review the official Natural Resources Canada air-source heat pump guide.
Heat Pump vs Air Conditioner: Quick Comparison
| Feature | Heat Pump | Air Conditioner |
|---|---|---|
| Summer cooling | Yes | Yes |
| Winter heating | Yes | No |
| Refrigeration cycle | Heating and cooling | Cooling only |
| Separate heating system required | Depends on design and backup strategy | Yes for winter heating |
| Can pair with gas furnace | Yes, as dual fuel | Yes, for furnace heating plus AC cooling |
| Heating efficiency metric | HSPF2 and other heating performance data | Not applicable |
| Cooling efficiency metric | SEER2 and EER2 | SEER2 and EER2 |
| Cold-weather performance data | Important | Not used for space heating |
| Defrost cycle | Used during winter heating when required | Not part of normal winter heating operation |
| Annual HVAC use | Potentially heating and cooling seasons | Primarily cooling season |
| BC heat pump incentives | May qualify under current programs if requirements are met | Cooling-only AC is not the same qualifying heat-pump upgrade |
1. Heat Pumps Provide Heating and Cooling
This is the most important difference.
Air Conditioner
A conventional residential air conditioner removes heat from the home during warm weather.
Another system must provide winter heating, such as:
- Gas furnace
- Electric furnace
- Boiler
- Electric baseboards
- Another heat pump
Heat Pump
An air-source heat pump provides:
- Cooling in summer
- Heating in winter
ENERGY STAR describes a ducted air-source heat pump as similar to a central air conditioner that can also operate in reverse to provide space heating.
This Does Not Automatically Mean the Heat Pump Replaces Every Other Heating Component
System design may include:
- Heat pump only
- Heat pump with electric supplementary heat
- Heat pump with gas furnace
- Ductless heat pumps with existing baseboards retained in selected areas
2. Cooling Operation Is Very Similar
Homeowners sometimes assume a heat pump is a weaker air conditioner because it also heats.
That is not how the technology works.
In Cooling Mode
A correctly selected heat pump performs the same fundamental refrigeration task as a central air conditioner:
- Indoor coil absorbs heat
- Compressor circulates refrigerant
- Outdoor coil rejects heat
- Condensate removes indoor moisture
Actual Cooling Performance Depends On:
- Equipment capacity
- SEER2 and EER2 performance
- Indoor airflow
- Refrigerant charge
- Ductwork
- Outdoor temperature
- Equipment sizing
Compare Actual Matched Systems
Do not assume a heat pump automatically cools better or worse than an air conditioner.
Compare the specific equipment combinations being quoted.
3. An Air Conditioner Needs a Separate Heating System
A central AC is only one half of the year-round comfort system.
Common Furnace + AC Arrangement
A typical ducted home may use:
- Gas furnace for winter heating
- Central air conditioner for summer cooling
- Same furnace blower and ducts for both
Heat Pump + Furnace
Replacing the AC with a heat pump can create a dual-fuel configuration where:
- Heat pump provides cooling
- Heat pump provides heating during selected conditions
- Gas furnace remains available for backup or changeover heating
Heat Pump + Air Handler
The furnace can also be removed and replaced with an electric air handler where a full-electric design is appropriate.
Compare What Equipment You Will Still Need in Ten Years
An AC-only decision can make sense today while leaving a separate heating-system replacement waiting later.
That future equipment should be part of the current planning discussion when the furnace is already aging.
4. Heat Pumps Operate During Winter
An air conditioner normally sits idle during the heating season.
A heat pump can continue operating as the home’s heating equipment.
Winter Heat-Pump Operation Can Include:
- Variable compressor output
- Long heating cycles
- Outdoor coil frost
- Defrost cycles
- Supplementary heating where required
Cold-Climate Heat Pumps
Modern cold-climate equipment is designed for improved low-temperature heating performance.
Current ENERGY STAR cold-climate criteria include minimum efficiency, low-ambient COP and low-temperature capacity requirements for qualifying systems.
See the official ENERGY STAR heat pump criteria.
An Air Conditioner Avoids These Winter Functions Because It Is Not Heating
That does not make the AC mechanically superior. It simply has a narrower job description.
5. Efficiency Ratings Are Not Identical
Because a heat pump provides both heating and cooling, it needs performance information for both modes.
SEER2
SEER2 is used to describe seasonal cooling efficiency.
It can be used when comparing both:
- Air conditioners
- Heat pumps
EER2
EER2 provides another cooling-efficiency metric under defined test conditions.
HSPF2
HSPF2 is a seasonal heating-efficiency metric for heat pumps.
A cooling-only air conditioner does not have heat-pump heating performance to rate.
Low-Temperature Capacity
For a BC heat pump, also review:
- Heating capacity at low outdoor temperature
- COP at low outdoor temperature
- Minimum operating temperature
Do Not Buy From SEER2 Alone
A homeowner choosing between AC and heat pump needs to evaluate both:
- Summer cooling performance
- Winter heat-pump performance
when the equipment will be used for heating.
6. Heat Pumps Have Additional Components and Control Functions
Heat pumps and air conditioners share many refrigeration components, but heat pumps need additional functions to switch between heating and cooling.
Heat Pump Controls May Include:
- Reversing-valve operation
- Defrost control
- Outdoor coil temperature sensing
- Supplementary-heat control
- Dual-fuel changeover
Reversing Valve
This allows the refrigeration circuit to change direction so the indoor and outdoor coils exchange roles between heating and cooling.
Defrost
When frost develops on the outdoor coil during winter heating, the heat pump periodically needs to clear it.
Air Conditioner Controls Are Focused on Cooling
A conventional AC does not need to manage winter compressor heating, defrost or heating-source changeover.
7. Installation Cost Must Be Compared as a Complete HVAC Project
A cooling-only air conditioner may have a different initial equipment and installation cost from a comparable heat pump.
But the useful comparison depends on what else the home needs.
Scenario A: New Furnace, Failed AC
If the furnace is relatively new and only the cooling equipment needs replacement, compare:
- New AC paired with existing furnace
- Heat pump paired with existing furnace
Scenario B: Furnace and AC Both Aging
Compare:
- New furnace + new AC
- New furnace + heat pump
- Full-electric heat pump + air handler
Scenario C: No Existing Cooling
If you are paying to install cooling for the first time, evaluate whether the same project can also reduce dependence on the existing heating system.
Installation Cost Can Be Affected By:
- Equipment capacity
- Indoor coil or air handler
- Furnace compatibility
- Duct modifications
- Electrical work
- Refrigerant piping
- Thermostat and controls
- Permits
- Commissioning
Get Both Alternatives Priced to the Same Scope
A quote for basic AC replacement should not be compared with a heat-pump quote containing new controls, ductwork and electrical improvements without accounting for the different work.
8. Operating Cost Depends on What Heating Source the Heat Pump Replaces
During cooling, operating cost depends on the specific efficiency of the AC or heat pump being compared.
The larger difference appears during heating.
Heat Pump Replacing Electric Resistance Heating
Heat pumps transfer heat rather than creating all space heat through electrical resistance.
This can substantially reduce the electricity required for space heating compared with:
- Electric baseboards
- Electric furnace
- Portable resistance heaters
Heat Pump Supplementing a Gas Furnace
The result depends on:
- Heat pump COP
- Furnace efficiency
- Electricity rate
- Gas rate
- Outdoor temperature
- Control strategy
Air Conditioner Does Not Change Winter Heating Cost Directly
A cooling-only AC leaves winter heating to the existing furnace, boiler or electric system.
Compare Annual Energy, Not Only Summer Cooling Cost
If the heat pump will actually be used for heating, the decision should include the full heating and cooling year.
9. Proper Sizing Matters in Both Heating and Cooling
A common mistake is selecting equipment from the old AC tonnage and stopping there.
Air Conditioner Sizing
The equipment should match the home’s cooling load.
Heat Pump Sizing
The contractor also needs to consider:
- Heating load
- Cooling load
- Low-temperature heating capacity
- Backup-heating strategy
Oversizing Can Cause:
- Frequent cycling
- Uneven comfort
- Poor summer humidity control
- Higher airflow and noise problems
Undersizing Can Cause:
- Failure to maintain temperature
- Long high-capacity operation
- Greater reliance on backup heating
Evaluate the Existing Ducts
Both AC and ducted heat pumps depend on correct airflow.
A new outdoor unit will not repair:
- Undersized return ducts
- Crushed flex duct
- Disconnected branches
- Excessive static pressure
10. Heat Pumps Have Additional Winter Operating Behaviour
A homeowner moving from furnace + AC to heat pump operation should expect some differences.
Longer Heating Runtime
Heat pumps, particularly variable-capacity systems, may operate for long periods at reduced output.
Supply Air Can Feel Different
Heat-pump heating commonly feels less hot at the register than gas-furnace heating.
That does not mean the system is failing if the home maintains temperature.
Outdoor Frost
Light frost can form during heating and is periodically removed through defrost.
Steam During Defrost
Visible vapour around the outdoor unit during a successful defrost can be normal.
Backup Heat
Depending on the system, heating may be supplemented by:
- Electric resistance heat
- Gas furnace
- Another designed backup source
A conventional AC owner does not encounter these behaviours because the outdoor cooling equipment is not responsible for winter heating.
11. BC Permits and Incentives Can Differ
A heat pump is regulated equipment in British Columbia.
Electrical Permit
Technical Safety BC states that most residential heat pump installations or upgrades require an electrical permit and regulated electrical work.
Gas Work
If a project removes or modifies an existing gas furnace or boiler, applicable gas work and permit requirements must also be addressed.
Review current information through the official Technical Safety BC heat pump guidance.
Heat Pump Incentives
Current Better Homes BC programs include air-source heat pump upgrade pathways under program-specific eligibility rules.
Requirements can involve:
- Existing heating system
- Household eligibility
- Equipment performance
- Registered contractor
- Heat distribution
- Permit compliance
- Documentation
Do Not Assume an AC Replacement Qualifies
Current heat pump programs are designed around qualifying heat-pump upgrades and specific heating-system requirements. A cooling-only AC replacement should not be assumed to receive the same incentive.
Check Before Installation
Program rules changed in July 2026 and can change again.
Review the current Better Homes BC Energy Savings Program requirements before relying on an incentive.
12. The Best Replacement Choice Depends on the Rest of the HVAC System
The outdoor AC or heat pump should not be selected in isolation.
Existing Furnace
Check:
- Age
- Condition
- Blower capacity
- Efficiency
- Thermostat compatibility
Existing Ductwork
Check:
- Airflow
- Static pressure
- Return-air capacity
- Duct leakage
- Room balancing
Electrical System
Check:
- Panel capacity
- Available circuits
- Outdoor disconnect
- Backup electric heat where applicable
Long-Term Heating Plan
Ask whether the homeowner intends to:
- Keep gas heating indefinitely
- Reduce gas use
- Convert to full electric
- Replace baseboards
- Add another zone later
The answer can make a heat pump much more useful than installing another cooling-only condenser.
Does a Heat Pump Cool as Well as an Air Conditioner?
Yes, a correctly selected and installed heat pump can provide effective residential air conditioning.
Natural Resources Canada specifically notes that heat pumps provide cooling using the same underlying technology familiar to homeowners with air conditioners.
Cooling Quality Depends On:
- Correct equipment sizing
- SEER2 and EER2 performance
- Indoor airflow
- Refrigerant commissioning
- Ductwork
- Indoor-unit location for ductless systems
Humidity Control
A system that is significantly oversized can reach the thermostat setpoint quickly and shut down before removing as much indoor moisture as a better-matched system.
Variable-Capacity Equipment
Modern variable-speed heat pumps can reduce cooling output during lower-load conditions and operate for longer periods.
This can help maintain steadier temperature and humidity when the system is properly designed.
Can You Replace an Air Conditioner With a Heat Pump?
Often, yes.
This is one of the most natural opportunities to consider a heat pump because much of the basic cooling infrastructure already exists.
The Contractor Should Still Check:
- Indoor coil or air handler compatibility
- Existing furnace blower
- Duct airflow
- Refrigerant-line requirements
- Thermostat and controls
- Electrical supply
Do Not Assume It Is a Direct Outdoor-Unit Swap
The existing indoor coil may not be compatible with the new heat pump.
A new matched indoor coil or air handler may be required.
Furnace + Heat Pump
If the furnace is retained, the result can be a dual-fuel system.
ENERGY STAR specifically identifies replacing an older central AC with a heat pump while retaining a relatively new furnace as a hybrid option worth considering.
Can You Keep Your Gas Furnace With a Heat Pump?
Yes, when the equipment and controls are compatible.
Typical Hybrid Operation
The heat pump can provide:
- Summer cooling
- Heating during selected outdoor conditions
The furnace can provide heating when the hybrid controls call for it.
Why Keep the Furnace?
- It may still have useful service life.
- It provides backup heating capacity.
- It avoids installing large electric resistance backup in some designs.
- The existing duct system and blower may already be suitable.
Compatibility Must Be Verified
Do not assume every furnace can be paired with every heat pump.
Check:
- Blower airflow
- Indoor coil match
- Control strategy
- Equipment ratings
Can a Heat Pump Replace Both the Air Conditioner and Furnace?
Yes, in homes where the system is designed to provide the required heating and cooling capacity.
A Full-Electric Central System May Include:
- Outdoor heat pump
- Electric air handler
- Central ductwork
- Electric supplementary heat where required
- Compatible thermostat or controller
Before Removing the Furnace, Review:
- Home heating load
- Low-temperature heat pump capacity
- Electrical service
- Backup-heating design
- Duct airflow
Do Not Assume Full Electric Means No Backup Planning
The system should be designed around the actual peak heating requirement and expected heat-pump performance.
What if Your Gas Furnace Is Still Relatively New?
This is where a heat pump can be especially interesting.
Option 1: Replace the Failed AC With Another AC
The furnace remains the winter heating source.
Option 2: Replace the AC With a Heat Pump
The furnace remains installed, but the heat pump can provide:
- Cooling
- Electric heating
according to the designed hybrid control strategy.
Evaluate the Incremental Project Difference
Ask for complete quotes for both options rather than assuming the price difference from online equipment listings.
Check Furnace Blower Capability
A newer furnace can still have airflow or compatibility limitations that affect the heat-pump pairing.
What if Both the Furnace and Air Conditioner Are Old?
This is a good time to reconsider the entire HVAC design.
Possible Options Include:
- New furnace + new AC
- New furnace + heat pump
- Full-electric central heat pump
- Central plus ductless combination
Do Not Replace Two Old Systems Automatically With Two New Versions of the Same Design
Review:
- Current building load
- Ductwork
- Electrical system
- Utility strategy
- Available heat-pump incentives
- Cooling needs
A home that has changed through insulation, renovations or window upgrades may no longer need equipment sized like the original system.
Heat Pump vs Air Conditioner for a Home With Electric Baseboards
A cooling-only AC normally does nothing to reduce baseboard heating use.
A heat pump can provide both cooling and electric compressor heating.
Ductless Heat Pumps Are Commonly Considered Where No Central Ductwork Exists
A ductless system can serve:
- Main living area
- Bedrooms
- Basement
- Suite
depending on the design.
Existing Baseboards May Remain
They can serve:
- Rooms without adequate heat-pump coverage
- Supplementary heating
- Backup heating
Air Conditioner Alone Does Not Create This Heating Opportunity
For an electrically heated home adding cooling, comparing ductless AC with ductless heat-pump equipment should include the potential winter use.
Ductless Heat Pump vs Room Air Conditioner
Homes without central ductwork have several cooling options.
Window or Portable AC
These typically provide cooling to a limited area.
Ductless Heat Pump
A permanently installed mini-split can provide:
- Cooling
- Heating
- Variable-capacity operation
- Dedicated room or zone control
Installation Is More Involved
Ductless heat pumps require:
- Outdoor unit
- Indoor unit
- Refrigerant piping
- Condensate drainage
- Electrical work
- Wall penetration
Compare the Job Being Performed
A window AC and whole-home multi-zone heat pump are not equivalent products simply because both can lower indoor temperature in July.
What Is a Cold-Climate Heat Pump?
A cold-climate heat pump is designed and certified for stronger performance at lower outdoor temperatures.
Current ENERGY STAR Criteria
For qualifying split heat pumps, current cold-climate requirements include defined:
- Seasonal efficiency thresholds
- Low-ambient COP
- Heating-capacity retention at approximately -15°C
- Controls verification
Why This Matters in BC
British Columbia includes very different climates.
Equipment suitable for Metro Vancouver should not automatically be assumed to provide identical performance in colder interior or northern communities.
Even in Metro Vancouver, Check the Performance Data
Review:
- Heating capacity at low temperature
- COP
- Minimum operating temperature
- Defrost behaviour
before deciding how much winter heating the heat pump should provide.
Heat Pump vs Air Conditioner for Comfort and Humidity
During summer, both can provide excellent comfort when sized and commissioned correctly.
Temperature Control
Variable-capacity systems can reduce output during mild cooling demand rather than repeatedly switching between full output and off.
Humidity
Cooling removes moisture as indoor air passes across a cold coil.
Effective humidity control depends on:
- Equipment sizing
- Coil temperature
- Airflow
- Runtime
- Fan controls
Bigger Is Not Better
A significantly oversized AC or heat pump can cool the thermostat area quickly but run shorter cycles that provide less moisture removal.
Is a Heat Pump Louder Than an Air Conditioner?
Not inherently.
Sound depends more on the specific model, capacity, compressor technology and installation.
Both Systems Have Outdoor:
- Compressor
- Fan
- Refrigerant flow
Heat Pumps Also Run in Winter
That means outdoor sound may be noticed at times when an air conditioner would be off.
Winter Heat-Pump Sounds Can Include:
- Compressor modulation
- Reversing-valve changes
- Defrost operation
- Outdoor fan starting and stopping
Placement Matters
Consider:
- Bedroom windows
- Neighbouring homes
- Wall vibration
- Service clearances
rather than selecting the outdoor location solely because it saves a few metres of piping.
Heat Pump vs Air Conditioner Maintenance
Many maintenance requirements overlap because the equipment shares refrigeration technology.
Both May Need:
- Filter maintenance
- Indoor coil inspection
- Outdoor coil cleaning
- Condensate-drain inspection
- Electrical checks
- Refrigerant-system evaluation where indicated
- Blower and fan inspection
Heat Pumps Also Need Winter Functions Checked
Depending on equipment, service may include:
- Heating operation
- Defrost
- Outdoor sensors
- Reversing valve
- Supplementary heating
- Dual-fuel changeover
Refrigerant Is Not a Consumable
Neither a heat pump nor air conditioner should need routine seasonal refrigerant top-ups.
If refrigerant charge is low, a leak or previous charging problem should be investigated.
Does a Heat Pump Wear Out Faster Than an Air Conditioner?
Do not assume a fixed lifespan difference solely from the equipment category.
A heat pump may operate during both heating and cooling seasons, while an AC normally operates only for cooling.
However, service life also depends on:
- Installation quality
- Equipment design
- Runtime
- Maintenance
- Coil condition
- Electrical conditions
- Environment
Variable Equipment Can Accumulate Long Runtime at Low Output
Hours of operation do not directly translate into equivalent mechanical stress across all systems.
Installation Quality Matters More Than Internet Lifespan Numbers
Incorrect airflow, refrigerant charge, electrical setup or outdoor placement can shorten the life of either system.
Do Heat Pumps Need Different Electrical Work Than Air Conditioners?
The electrical requirements depend on the exact equipment.
Both Systems Need:
- Appropriate electrical supply
- Overcurrent protection
- Disconnecting means
- Control wiring
A Full-Electric Heat Pump Project Can Include Additional Loads
For example:
- New air handler
- Electric supplementary heat
which can make the project very different from replacing one existing central AC condenser.
Dual Fuel Can Be Different Again
A heat pump paired with a gas furnace may not require the same large electric backup-heating capacity as a full-electric central system.
Have the Electrical Scope Reviewed Before Ordering Equipment
Do not assume either that a panel upgrade is definitely required or that the existing electrical system is automatically adequate.
What Permits Are Required for a Heat Pump in BC?
Technical Safety BC currently identifies residential heat pumps as regulated electrical equipment.
In most cases, installation or upgrade requires an electrical permit and appropriately qualified electrical work.
Replacing Gas Heating Too?
If the project modifies or removes a natural gas furnace or boiler, applicable gas-permit requirements also need to be addressed.
Jurisdiction Matters
The authority can be:
- Technical Safety BC
- An applicable municipality
depending on location.
Ask the Contractor:
- Which permits are required?
- Who obtains them?
- Are permit costs included?
- What inspection or final documentation is provided?
Does a Heat Pump Qualify for Better Incentives Than an Air Conditioner?
Current BC energy-upgrade programs include specific incentive pathways for qualifying heat pumps.
Eligibility is not based simply on buying equipment that can cool.
Current Heat-Pump Requirements Can Include:
- Existing primary heating system
- Household eligibility
- Heat pump serving as primary heating
- Eligible equipment performance
- Registered contractor
- Permit compliance
- Required documentation
Rules Changed on July 6, 2026
Better Homes BC currently publishes program requirements effective for invoices dated on or after July 6, 2026.
Check Before Equipment Is Ordered
Do not choose between AC and heat pump based on a rebate amount copied from an older website, neighbour’s invoice or previous year’s program.
Review the current Better Homes BC requirements and confirm eligibility for the actual property, equipment and contractor before installation.
Heat Pump vs Air Conditioner: Which Is Better for Your Home?
Choose the Heat Pump Option for Serious Consideration When:
- You are replacing an AC anyway.
- You want the outdoor equipment to provide winter heating.
- You want to reduce electric baseboard use.
- You want dual-fuel heating with a gas furnace.
- You are planning eventual full electrification.
- A current heat-pump incentive could apply to the project.
Consider a Conventional AC When:
- The objective is strictly cooling.
- The existing heating system is intentionally remaining the sole winter system.
- The complete AC project better fits the building and homeowner priorities.
When Both Furnace and AC Are Near Replacement
Do not make the decision component by component.
Compare complete designs for:
- Furnace + AC
- Furnace + heat pump
- Full-electric heat pump
Compare the Same Information for Every Proposal
- Exact models
- Heating capacity
- Cooling capacity
- Low-temperature performance
- Efficiency
- Duct modifications
- Electrical work
- Controls
- Permits
- Commissioning
- Warranty
What Should a Heat Pump or Air Conditioner Quote Include?
| Quote Item | What Should Be Clear |
|---|---|
| Outdoor equipment | Exact model and capacity |
| Indoor equipment | Coil, air handler or furnace model |
| Heating capability | Heat pump heating and backup strategy where applicable |
| Cooling performance | Capacity and efficiency of matched system |
| Ductwork | Required modifications, sealing or airflow work |
| Electrical work | Circuits, disconnects and panel work |
| Controls | Thermostat and hybrid controls where applicable |
| Refrigerant piping | Replacement, reuse or modifications |
| Drainage | Cooling condensate and heat-pump defrost considerations |
| Permits | Responsibility and included fees |
| Commissioning | Airflow, controls and refrigeration testing |
| Warranty | Manufacturer and labour coverage |
Ask for the Heat Pump Alternative When Replacing an AC
Even if you ultimately choose the air conditioner, having both proposals gives you enough information to compare the total project rather than wondering afterward what the other option would have cost.

Heat Pump vs Air Conditioner: Frequently Asked Questions
What is the main difference between a heat pump and an air conditioner?
Both can cool the home, but a heat pump can also reverse its refrigeration cycle to provide heating.
Does an air conditioner provide heat?
A conventional cooling-only central air conditioner does not provide heat-pump space heating. A separate heating system is required.
Does a heat pump provide air conditioning?
Yes. An air-source heat pump provides cooling by transferring indoor heat outdoors.
Does a heat pump cool as well as an AC?
Yes, when the equipment is properly sized, matched, installed and commissioned. Compare the actual cooling capacity and efficiency of the proposed systems.
Is a heat pump just an air conditioner in reverse?
That is a useful simplified description. In cooling mode they perform closely related refrigeration functions, while a heat pump can reverse refrigerant flow to provide heating.
Does a heat pump use the same ducts as an air conditioner?
A central ducted heat pump can use the same distribution concept, provided the ducts and blower can support the required airflow.
Can I replace my central AC with a heat pump?
Often yes. The contractor should verify the indoor coil, furnace or air handler, ducts, electrical supply, refrigerant piping and controls.
Can I keep my furnace when I install a heat pump?
Yes, if the equipment is compatible. The combination can operate as a dual-fuel system.
Why would I keep a furnace with a heat pump?
The furnace can provide backup or changeover heating while the heat pump provides cooling and part of the annual heating load.
Can a heat pump completely replace my furnace?
Yes in an appropriately designed full-electric system. The home heating load, low-temperature heat-pump capacity, electrical system and backup strategy should be evaluated first.
Is a heat pump better if my furnace is new?
It can be attractive because the furnace can remain in service while the heat pump replaces an older AC and adds electric heating capability.
What if my furnace and AC are both old?
Compare complete furnace-plus-AC, furnace-plus-heat-pump and full-electric heat-pump options rather than automatically replacing both systems with the same technologies.
Is a heat pump more expensive to install than an AC?
The installed difference is project-specific. Compare complete equipment, controls, electrical work, indoor components, permits and any required duct modifications.
Is a heat pump cheaper to run than an AC?
For cooling, compare the actual cooling efficiency of the two systems. A heat pump’s additional value comes from its ability to provide heating.
Does a heat pump save money in winter?
It can, particularly when replacing electric resistance heating. Comparisons with gas heating depend on electricity rates, gas rates, furnace efficiency, heat-pump COP and weather.
Does a heat pump use more electricity than an AC?
A heat pump may use more annual electricity because it can operate during both heating and cooling seasons. Annual electricity alone does not show whether total heating and cooling energy cost improved.
Why did my electricity bill increase after replacing AC and gas heating with a heat pump?
Electricity is now providing heating that was previously supplied by gas or another fuel. Compare total energy costs rather than the electricity bill alone.
Is a heat pump more efficient than electric baseboards?
Heat pumps can deliver substantially more useful heat per unit of electricity than electric resistance heating because they transfer heat rather than generating all heat directly from electricity.
Can I install a heat pump in a home with baseboards?
Yes. Ductless heat pumps are commonly considered for homes without central ducts, with baseboards retained where needed for supplementary or unserved areas.
Do I need ducts for a heat pump?
No. Heat pumps are available in ducted and ductless configurations.
Do I need ducts for central air conditioning?
A conventional central AC uses ducts, but room and ductless cooling systems are also available.
What is SEER2?
SEER2 is a seasonal cooling-efficiency metric used for both air conditioners and heat pumps.
What is HSPF2?
HSPF2 is a seasonal heating-efficiency metric used for heat pumps.
Does an air conditioner have an HSPF2 rating?
A cooling-only air conditioner does not provide heat-pump heating, so HSPF2 is not its relevant operating metric.
What is EER2?
EER2 is a cooling-efficiency metric measured under defined test conditions.
Should I buy the system with the highest SEER2?
Not automatically. Equipment sizing, installed cost, heating performance, controls, airflow, reliability and the complete matched system also matter.
What is a cold-climate heat pump?
It is a heat pump meeting defined low-temperature performance requirements, including heating capacity and efficiency criteria.
Do I need a cold-climate heat pump in Vancouver?
The equipment should be selected from the home’s heating load and local design conditions. Cold-climate performance can still be valuable because it shows how the system performs as outdoor temperature falls.
Does a heat pump stop heating at 0°C?
No. Modern air-source heat pumps can operate below freezing. Capacity, efficiency and minimum operating temperature vary by model.
Does an AC work in winter?
A conventional cooling-only AC is not intended to provide winter heat.
Why does a heat pump frost outside?
During heating, the outdoor coil can become cold enough for moisture to freeze on it. The heat pump periodically uses defrost to clear the frost.
Does an air conditioner need a defrost cycle?
Not as part of normal residential winter heating because a cooling-only AC is not operating as an outdoor evaporator for space heating.
Why does steam come from a heat pump in winter?
Visible vapour can occur when frost melts from the outdoor coil during defrost.
Does a heat pump make more noise than an AC?
Not necessarily. Sound depends on the model and installation. A heat pump is simply used during more of the year, so homeowners may hear outdoor operation during winter as well.
Are variable-speed heat pumps quieter?
They can operate at reduced compressor and fan speeds during lower demand, but actual sound performance should be compared using the specific equipment ratings and installation location.
Is a heat pump harder to maintain?
Many maintenance tasks are similar to AC maintenance, but a heat pump also has winter heating, defrost and reversing functions that need to operate correctly.
Does a heat pump need refrigerant every year?
No. A sealed heat pump or air conditioner should not consume refrigerant during normal operation.
Does an air conditioner need refrigerant every year?
No. Repeatedly low refrigerant indicates a leak or charging problem that should be diagnosed.
Does a heat pump wear out faster because it runs year-round?
It may accumulate more annual operating time, but equipment life depends on many factors including installation, maintenance, load, operating conditions and equipment design.
How long does a heat pump last?
There is no guaranteed lifespan for every installation. Equipment condition, maintenance, coastal exposure, operating hours and installation quality all affect service life.
How long does an AC last?
Service life varies for the same reasons. Avoid making replacement decisions solely from a generic age number.
Does a heat pump require a special thermostat?
It requires controls compatible with its heating, cooling, reversing-valve and backup-heating functions. Some variable-capacity systems use manufacturer-specific communicating controls.
Can my existing AC thermostat control a heat pump?
Possibly not. Compatibility and available control functions should be verified before equipment selection.
Can a smart thermostat control a heat pump?
Some can. The thermostat must support the specific heat pump, compressor stages, auxiliary heating and dual-fuel configuration where applicable.
Does a heat pump require more electrical capacity than an AC?
It depends on the equipment and system design. A full-electric installation with electric supplementary heat can have different electrical requirements from a cooling-only AC replacement.
Does replacing my AC with a heat pump require a permit in BC?
Technical Safety BC states that most residential heat pump installations or upgrades require an electrical permit. The applicable authority depends on jurisdiction.
Who applies for the heat pump permit?
When regulated work is performed by a licensed contractor, the contractor normally handles the applicable permit for its work. Confirm responsibility in the proposal.
Does removing a gas furnace require a gas permit?
Gas-equipment modification or removal involves regulated gas work and applicable permit requirements.
Are there heat pump rebates in BC in 2026?
Yes, current Better Homes BC programs include qualifying heat-pump pathways, but eligibility varies by program, property, household, existing heating system, equipment and contractor.
Are there rebates for replacing only my AC?
Do not assume a cooling-only AC replacement qualifies under heat-pump programs. Current incentives have specific heat-pump and space-heating requirements.
Should I choose a heat pump only because of the rebate?
No. The equipment should first fit the home’s heating and cooling design. Incentives should support a suitable project, not determine the HVAC system by themselves.
Can a heat pump work with my existing furnace ducts?
Possibly. The ducts should be evaluated for airflow, static pressure, leakage and room distribution.
Why might my ducts work for a furnace but not work well for a heat pump?
The required airflow and operating pattern can differ. Existing return restrictions or undersized ducts may become more noticeable with the new equipment.
Should static pressure be checked before heat-pump installation?
For a ducted retrofit, static-pressure and airflow evaluation can help determine whether the existing distribution system can support the proposed equipment.
Does a heat pump dehumidify like an air conditioner?
Yes, cooling operation removes moisture from indoor air. Humidity performance depends on sizing, airflow, runtime and controls.
Can an oversized heat pump make the home humid?
Oversized cooling equipment can run shorter cycles, potentially reducing moisture removal.
Can an oversized AC cause the same problem?
Yes. Oversizing can hurt cooling comfort and humidity control in either technology.
Which is better for a condo: heat pump or AC?
It depends on heating needs, available outdoor-unit location, strata rules, electrical capacity, drainage and whether the system is intended to provide year-round comfort.
Which is better for a townhouse?
Evaluate the same factors plus multi-floor heat distribution and whether existing ducts can support a central system.
Which is better for a house with no ducts?
Ductless heat pumps are often attractive because they provide both heating and cooling without adding a central duct system.
What if I only need cooling upstairs?
A targeted cooling system may be enough, but a ductless heat pump can also provide heating to that zone. Compare the complete use case before selecting cooling-only equipment.
Can I combine a central heat pump with ductless units?
Yes. Some homes use a central system for most rooms and ductless equipment for additions, suites or difficult areas.
Should I replace an operating AC with a heat pump?
Not automatically. Consider the age and condition of the AC, heating-system plans, energy goals, incentives and whether replacing functional equipment early makes financial sense.
When is the best time to consider a heat pump instead of an AC?
When the existing AC needs replacement, new cooling is being added, the furnace is being replaced or the homeowner is planning a broader heating-system change.
What should I ask the contractor before choosing?
Ask for exact model numbers, heating and cooling capacities, low-temperature performance, sizing method, duct review, electrical scope, backup-heating strategy, permits, commissioning and warranty.
Does Bernoulli provide heat pump installation estimates?
Bernoulli Heating and Cooling currently provides free estimates for new heat pump installation projects across Metro Vancouver and Fraser Valley.
How much is a Bernoulli diagnostic appointment for an existing heat pump?
The current diagnostic appointment charge is $135. Repair labour, refrigerant, replacement parts and additional materials are separate.
