Understanding the truth behind heat pump myths in winter
At AirGreen, we know that Québec winters raise a lot of questions when it comes to heating with a heat pump. From doubts about their performance in sub-zero temperatures to myths around energy consumption, it’s time to set the record straight. Today, we’re shining a light on 7 common myths that still prevent some homeowners in Montréal, Laval, Longueuil, the North Shore and South Shore from adopting this modern, eco-friendly, and cost-effective solution.
Myth #1: Heat pumps don’t work well in the winter
This is probably the most widespread myth. Many believe heat pumps become useless once the temperature drops below zero. But in reality, the latest models — like the Fujitsu KZAH R-32 or the Gree Extrême — are built to operate efficiently even at temperatures as low as -30°C. With variable-speed compressors and advanced defrost technologies, we regularly install wall-mounted heat pumps that keep homes comfortable all winter long, even during deep freezes on the North Shore.
Myth #2: A heat pump uses a lot of electricity
This is another persistent misconception. In fact, a modern, properly installed heat pump can produce up to 3 kWh of heat for every 1 kWh of electricity it consumes. For example, a Bosch BIVA IDS Premium R-454B system we recently installed in Longueuil for a residential client helped reduce their annual heating consumption by over 30%, thanks to its high Coefficient of Performance (COP) and smart programming, fully optimized by our technicians.
Myth #3: An electric furnace is more reliable than a heat pump
While electric furnaces have long been the standard, central and wall-mounted heat pumps today are just as reliable—as long as they’re properly sized and maintained. Our teams in Montréal provide comprehensive HVAC maintenance every season to ensure optimal performance, extend the system's life, and give homeowners complete peace of mind.
Myth #4: Heat pumps don’t work in large homes
False. For larger houses, we often recommend and install central ducted systems, such as GOODMAN R-32 air handlers paired with powerful compressors. With proper zoning and well-designed ductwork, it’s absolutely possible to evenly heat large homes in Brossard, Blainville, and even Saint-Jérôme.
Myth #5: You always need a backup heating system
Another half-truth. While some older heat pumps needed a backup, that’s no longer the case with the latest inverter technology models. In a recent install in Sainte-Julie, for example, we set up an 18,000 BTU Gree Sapphire with a smart system that only switches to a small electric backup heater during prolonged extreme cold—maximizing cost efficiency without sacrificing comfort.
Myth #6: Heat pumps are too expensive upfront
True, the initial investment can be higher than a simple baseboard heater. But think about the long-term return. Considering Hydro-Québec’s LogisVert subsidies (up to $2,172 in some cases), lower heating bills, and a boost in property value, the return on investment becomes very attractive. In Laval, one of our customers who opted for a 15,000 BTU Sharp ZU1 saw a full payback in under three winters.
Myth #7: Heat pumps require lots of maintenance
Nope. Just minimal regular upkeep is needed: clean the filters monthly, have a professional check-up once a year, and that’s it. At AirGreen, we offer custom HVAC maintenance plans, which are especially popular in Verdun, Repentigny, and Saint-Lambert, to keep systems running smoothly without any headaches.
What we see in the field
Our certified technicians travel across Montréal and surrounding areas every week to install, maintain, or repair HVAC systems. Every home is unique, and every installation is carefully tailored to meet the client's specific needs. Recently, during a service call in Île-Bizard, we had to reposition a wall unit to better distribute airflow in an open-concept room with cathedral ceilings. Thanks to our field expertise, we were able to adjust the system and improve the room’s thermal coverage by 20%.
