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Many Ontario homeowners still hesitate to make the switch because of outdated assumptions or myths that no longer reflect today’s technology.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

Had furnace and air conditioning unit put in. They did an excellent job great price and everything clean as can be, I was very pleased
All winter I have had an issue with very little heat reaching the 2nd floor of our home. After this past winter ended I decided to look into this. I found Twintech Heating and Cooling on line and started the process. After explaining my problem I had a call form Twintech and the tech came out and walked through things with me. The problem was the heating vent pipe had been dropped down in size by someone years ago causing little heat reaching the 2nd floor. Further into checking out the older furnace and AC they found a few things not properly installed by the last install of the old furnace and also that the AC was on it's last legs. I asked for a quote and waited a few days and we decided to go ahead with Twintech. They called a few days before to set up an installation time and date. The day of the install the guys were a half hour early which was a plus. The day of the install was great, the guys worked away removing the old furnace and AC.After which they installed the new furnace and AC. After they cleaned up the basement with all their tools and scrap metal etc. they came back inside to walk thru what they did. They also tested both the furnace and cooling systems to make sure everything worked and I the customer was happy. I now have heat on the 2nd floor for next winter. The guys from Twin tech were very professional. Their work habits and knowledge of the job was excellent. Their workmanship was just excellent, it was just up there with my standards as a homeowner. I am very pleased to have chosen Twintech for my new furnace and AC.. If I had to rate this experience with Twintech this company is a 10 in my books.Product,workmanship and customer care says it all.
I called Twintech during the Covid 19 crisis because our furnace was broken and it was still very cold during the nights. Dave answered all of my questions by phone but wanted to come have a look but only if our family felt comfortable having someone visit during the uncertainty surrounding the pandemic and was able to attend that very same affternoon.
He was very courteous and informative but most importantly he respected his and our safety by wearing medical gloves in our home and maintaining proper physical distancing. He reviewed the various options of the products that suited our needs going over not only price but quality of workmanship, warrantees and where the product was manufactured which were all important factors in making such a large purchase. You could tell that Dave had been in this industry for a very long time.
The installation was done by a fine young gentleman the very next day and we now have a toasty warm home to ride out this crisis in while humming along at 96% efficiency!
I would recommend this very professional, small family business for anyone in need of HVAC equipment or maintenance.
My special thanks to Twintech teams! They had replaced my furnace and A/C, and installed a new humidifier for me 2 weeks ago. Dave, the sales manager, not only provided me with an honest quote on the best HVAC products with best quality and warranties, he also arranged portable heaters for me and sent supporting docs to energy company for energy audit. Above and beyond service!
Greg, Grant, Mitch had worked tirelessly and professionally to perform the HVAC installation. They worked with professional tools, and performed proper measurement readings after installation. They are very patient with all my questions, and very pleasant to communicate.
Great work guys! This company sure knows their products and they stand behind their services. My home comfort level has improved! I am glad that I can support an ethical and honest local family business.
Professional, flexible on price and delivered on time...well done. All you can ask for when getting a new furnace.
The work was done quickly and professionally. Workers were really polite and easy to work with.
Product works great!
Furnace broke down on a Wednesday, shopped around for prices and Friday Twintechs name came up from a referral from my wife's work. Called Dave 11 am, he came over around 1 pm. Gave me a very good price, I accepted. The guys were there two hours later to take the old furnace out and install the new one. All finished by 6:30pm. Finally heat.
They were very pleasant and helpful. As a result we are doing our A/C later this year with this company.
After some extensive research, we settled on Twintech for our new furnace. The service - from Dave's initial visit - through to the installation was absolutely fantastic.
Dave was super-patient with our many questions, did not try to "up-sell" us into buying things we don't need, knowledgeable, friendly and all-around an excellent Advisor.
I've forgotten the names of the installers but they were superb as well. They showed up on-time, did all the work with no mess or intrusion, removed the old furnace and installed the new one in one day; all with no impacts to our day-to-day life.
I cannot recommend Twintech enough, especially over any of 'bigger guys' who tried to sell us a bunch of thing we don't need. Twintech were fantastic and my wife and I are very pleased with our purchase.
From the minute I met Dave and discussed my new furnace needs I knew I was in good hands. He was patient, knowledgeable and very professional through the quotation process.
Grant and Greg did an outstanding job on the install. They did a great job of explaining the defects with my old furnace. The quality of the installation was excellent and the attention to detail was on another level. The old adage You get what you pay for couldnt be more true as I feel I received great value, skilled expertise and high quality customer service. I highly recommend Twintech for all your heating and cooling needs.
Glad to have found a not-too-big local firm that provided the needed expertise, quality workmanship, and competitive pricing as well. In and out in one day, removed the old units, did a nice job installing all of the new units, and left no debris. Even have a service contract that far outshined the big company offerings. Would definitely recommend them.

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. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
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!
