A heat pump or an air conditioner? Which one is the best one to buy? The answer depends on your needs and deserves a thorough analysis.


Air conditioning

An air conditioner cools your home during big summer heatwaves by creating cold air through regular vapour compression.

There are central air conditioning systems, and there are wall-mounted units. As air-con units only run for a few months a year, they have a pretty good lifespan. However, it does not help you save on heating bills.


Heat pump

A heat pump system can both heat and cool your home. It cools the air in your house over the summer but heats your home in the winter when the temperature drops. As opposed to air-con units, which create cold air, heat pumps use hot and cold air transfer.

Like air conditioners, heat pumps come in central systems or mural units. Also, certain models come with multi-zone functions, which allow you to manage certain rooms or areas of the house independently.

Since they run for most of the year, heat pumps sometimes have a shorter lifespan than air conditioners. However, when used along with your regular heater, it helps you save on heating bills.



Many choose to buy an air conditioner, arguing that heat pumps are too expensive. This might have been true in the past, but today, heat pumps are priced nearly the same as air conditioners.

Additionally, thanks to the Hydro-Québec program, you can be granted government support when purchasing an eligible heat pump.

As for the “Renoclimat” program, it allows you to receive funding when purchasing an eligible heat pump recognized by NEEP while renovating your home for better energy efficiency.



Whether you choose an air conditioner or a heat pump as an HVAC system, you must determine the BTU (British Thermal Unit) amount needed for your unit to give you the best performance.

An expert’s evaluation of your house’s surface area, the number of floors, the ceiling height, and the insulation quality is a necessary step in this process.

Central air conditioning systems and central heat pumps’ power usually ranges between 24 000 and 60 000 BTU. As for the wall-mounted air conditioner and wall-mounted heat pump, they typically run between 9 000 and 18 000 BTU. The multi-zone wall-mounted heat pump’ output, on the other hand, ranges from 18 000 to 36 000 BTU.
