Heat Pump Myths Ontario Homeowners Should Stop Believing

Heat pumps have surged in popularity across Ontario thanks to their efficiency, cold-climate performance, and ability to replace or supplement traditional heating systems.
But with the rise in interest comes a rise in misinformation.
Many Ontario homeowners still hesitate to make the switch because of outdated assumptions or myths that no longer reflect today’s technology.
Below are the most common heat pump myths—debunked—so you can make informed decisions about your home’s comfort and energy efficiency.
Myth #1: Heat Pumps Don’t Work in Ontario Winters
This may have been true for older heat pump models, but modern cold-climate heat pumps are engineered specifically to operate efficiently in freezing temperatures.
Many systems continue delivering dependable heating at temperatures below –25°C.
Thanks to advancements like variable-speed compressors and improved refrigerants, today’s heat pumps maintain strong performance even through harsh Ontario cold snaps.
Myth #2: Heat Pumps Only Provide Air Conditioning
Heat pumps both heat and cool your home.
In summer, they work like an air conditioner; in winter, they extract heat from outdoor air and move it indoors.
Even in frigid weather, there is enough thermal energy outside for a cold-climate heat pump to operate.
That means one system provides year-round comfort.
Myth #3: Heat Pumps Are Too Expensive to Run
Many homeowners assume heat pumps cost more to operate than natural gas systems.
In reality, heat pumps are among the most efficient home heating systems available, and they can significantly reduce electricity consumption compared to electric resistance heating, baseboards, or older furnace/AC setups.
With Ontario’s energy prices and incentives, heat pumps often deliver substantial long-term savings.
Myth #4: Heat Pumps Can’t Heat Large or Older Homes
Heat pump systems come in a wide range of sizes and configurations.
With proper load calculations and professional installation, they can heat:
Older homes
Multi-level houses
Homes with additions
Larger floor plans
Ducted, ductless, and hybrid systems ensure there’s a solution for virtually any home type in the Durham Region and Toronto.
Myth #5: Heat Pumps Are Noisy
Modern heat pumps are remarkably quiet—many operate at noise levels lower than a conversation.
Thanks to variable-speed technology, the outdoor unit often runs at low, steady speeds instead of loud on/off cycles.
If noise is a concern, your HVAC installer can recommend models specifically designed for ultra-quiet performance.
Myth #6: They Don’t Last as Long as Furnaces
Heat pumps have become more durable in recent years, especially cold-climate models built for regions like Ontario.
With proper maintenance, many systems last 15–20 years, similar to furnaces and air conditioners.
Some premium brands also offer extended or top-tier warranties, protecting your investment long-term.
Myth #7: Heat Pumps Require Major Renovations
Heat pump installation is usually straightforward.
Depending on your home, you may need:
A ducted unit that connects to your existing ductwork
Ductless wall-mounted units
A combination of both
In most cases, homeowners don’t need extensive upgrades—just a professional assessment to ensure proper sizing and setup.
Myth #8: Heat Pumps Aren’t Environmentally Friendly
Heat pumps are one of the greenest HVAC options available.
Because they move heat instead of burning fuel, they reduce greenhouse gas emissions and lower your home’s carbon footprint.
Pairing a heat pump with Ontario’s increasingly clean electricity grid makes them even more environmentally beneficial.

Dave was great in helping me get the proper units for my property, as well as getting them installed. The installers arrived when they said they would, and completed the project on time, and professionally. If I needed another furnace, I would use Dave again.
I have known Greg and Grant Dainty for many years and have used their company for my house and business. I recommended them also for my parents and sister and they all have been very satisfied with the quality of work for a reasonable price. I just recently had them install a new HVAC system in an older house and was very pleased with their work. Craig in Pickering. After meeting with various heating and air conditioning contractors I was referred to Twin Tech Heating and Cooling through a family member. Greg and Grant arrived at my home and provided me with an estimate and a plan as to how they were going to remove and replace my furnace and air conditioner. On the day of install Greg and Grant arrived at my home on time and were very professional and extremely courteous as to any questions or concerns that I had. The removal and install was truly professional and the attention to detail was exactly what I was looking for. Ive seen many installs from other contractors and I couldnt be any happier to have had such a clean looking install. The sheet metal work, ducting and venting all look fantastic. Upon completion Greg and Grant left me feeling extremely happy and very fortunate of a job well done. Thanks again Twin Tech!!
My old furnace had finally broken down for the last time when contacted twintech to have a new furnace installed They were prompt, knowledgeable and very reasonably priced. They did such a great job i tell all my friends and family about this company.
To whom it may concern, I recently had TwinTech (Greg and Grant Dainty) replace my furnace and service both my gas fireplaces and air conditioning unit. They were professional, courteous and very fair in their pricing. I would gladly recommend TwinTech to anyone needing work done. I can be contacted at 905-626-XXXX.
My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.
Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers.

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
