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Many Ontario homeowners still hesitate to make the switch because of outdated assumptions or myths that no longer reflect today’s technology.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.


Heat Pumps: A Smart Choice for Ontario Homes


Modern heat pumps are efficient, quiet, reliable, and perfectly suited for Ontario’s winter climate.


If you've been unsure about switching to a heat pump because of outdated information, now is the perfect time to explore your options.


Twintech Heating & Cooling proudly installs, services, and maintains heat pumps across the Durham Region and Toronto—helping homeowners stay comfortable while saving energy.

Received a new range and needed someone to disconnect the old range and connect the new gas range. They did a thorough job and were kind enough to remove the old range from the house. Thank you!

by AJM in Pickering on Twintech Heating and Cooling

Very satisfied with this company! Salesperson Dave was very good, very knowledgeable and gave me the impression that he wanted to sell me what I needed rather than what would put the most money in the company's pocket. He also called back after the installation to see if I was satisfied with the result. The installation crew of Greg, Grant and Peter did a great job. They arrived on time, completed the job quickly, answered all my questions and thoroughly cleaned up. They told me to call if I had any further questions. They left me with the impression that they really cared about their work and my satisfaction and that it wasn't " just a job". Prior to researching for a new furnace, I had never heard of this company but I'm glad that I did and would highly recommend them to anyone looking for a new furnace or air conditioning unit. They may be small but they do a great job!!

by David from Toronto on Twintech Heating and Cooling

I first met Greg and Grant (The Twin Brothers from Twin Tech - yup -it's not just a cool company name) back in 2014 when our furnace broke down and they installed our Carrier Furnace and AC that we purchased through Sears. I liked them instantly when I met them due to their friendly and professional service, and the fact that they didn't mind taking a little extra time to explain things in terms I could understand. Since that time they have reached out to me at least once a year to ensure that everything was running smoothly with my system and to keep me appraised of their evolving services. Due to this high level of proactive customer service I didn't hesitate to call and obtain their help for a Gas Stove removal and installation. When I scheduled the call Greg and Grant let me know that they would arrive the morning of the appliance delivery to disconnect the old gas stove, and then return in the afternoon to connect the new stove. Sure enough, they did just that as promised. Where they exceeded my expectations is with the extra level of support helping to assemble the burners and grills on the stove and in the oven. This may seem like a small thing to some but to my wife who was at home during this entire process it meant a stress free transition to the meal prep for the day. When I called home to ask about the install she commented that, "they left the place cleaner than it was when they arrived and they setup all the grills on top of the stove and in the oven... they didn't have to do all that -Wow!". You know what they say, Happy Wife, Happy Life. So in summary, I am recommending Twintech Heating & Cooling for all of your Furnace, Air Conditioning, and Gas Line needs. I've even called on these guys to help swap out a leaky water valve. They are just so easy to reach and communicate with by phone, and they don't mind a text message to confirm the details. You can rest easy when you have the Twins on your side as an extension of your household maintenance plan.

by Jr in Pickering on Twintech Heating and Cooling

First thing, they actually showed up for a quote. Other big name companies in the area didn't even return my call , job was done as expected and new equipment is quiet and installed very clean and professional. Would highly recommend these guys.

by Melissa P. from Port Hope on Twintech Heating and Cooling

They removed our old furnace and replaced it with a new furnace and AC system.

by Nancy H. from Oshawa on Twintech Heating and Cooling

Work was performed in a clean and timely manner. The furnace and metal work was performed by the Twintech team (did not require separate contractor to do the metal work). Energy audit was arranged and promised rebates were received. The overall price was very competitive. We have recommended Twintech to several of our friends and family. Awesome job.

by Syd from Whitby on Twintech Heating and Cooling

Grant and Greg installed a heating and AC system in our new Linwood post and beam home. Post and beam can be challenging structures for running ductwork and their high ceilings and open concept frequently frustrate efforts at balancing air flow and controlling temperatures. But these guys did it and did it right the first time. Even the building inspector was impressed with what he saw. More importantly, the boys brought a high degree of trust and integrity to the job. Something in short supply these days.

by jenner iksmom from Oshawa on Twintech Heating and Cooling

Very polite and professional. They removed my o
ld furnace and A/C and installed my new ones. They were efficient and thoroughly cleaned up when they were done! I would highly recommend them!

by Rob from Toronto on Twintech Heating and Cooling

Pro from start to finish. They were able to fix my gas fireplace at very little cost as well.

by murray mcmichael from Ajax on Twintech Heating and Cooling

by Aaron on Twintech Heating and Cooling

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.

by Linda on Twintech Heating and Cooling

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!

by Robert Rogers on Twintech Heating and Cooling

Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.

by Robert Mizuno on Twintech Heating and Cooling

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!

by Ruth on Twintech Heating and Cooling

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!
