Heat Pump Myths Ontario Homeowners Should Stop Believing
Posted On: November 30, 2025
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Many Ontario homeowners still hesitate to make the switch because of outdated assumptions or myths that no longer reflect today’s technology.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.

We are very happy with our new furnace. The service was excellent the guys worked 6 hours straight through and there was no mess at all they took the old furnace boxs etc with them they then explained everything to us they were very helpful and pleasant , when we need a new air conditioner we know who to call!
May 12, 2020
The crew from sales to installation was very professional and had great attention to detail

We couldnt have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.
We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.
Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.
Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!

We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.

We were very pleased with every aspect of the work that was done. They were very professional and polite. They arrived when they said they would and job was completed on estimated time
We would highly recommend them to whoever needed a recommendation

The blower on our furnace stopped working leaving us with a cold house. Dave from TwinTech responded immediately to our HomeStars service request. From beginning to end Dave was nothing but helpful, friendly and professional, he did a great job of walking us through the quote and scope of work.
The replacement of the furnace went smoothly. The Guys did a great job, everyone was very friendly and polite. There were no hiccups, or unexpected costs. The only surprise was they left the work area cleaner than it was before they started.
Was a great experience with the whole TwinTech team. Its been a couple of months since the new furnace has been installed and its working great!

I heard about TwinTech when researching new furnaces at furnaceprices.ca. After contacting them about my broken down furnace, Dave came to my house the next day to assess my situation and requirements for a new furnace. He recommended one that had stainless steel heat exchangers which sold me since my previous furnace had issues with a rusted secondary heat exchanger that had to be replaced. Dave also set me up with an appointment with an energy audit company so that I could take advantage of a rebate to help improve the energy efficiency of my home and get some money back. A few days later, Greg, Grant, and Mitch came to install the new furnace and remove the old one. When delivering and removing the furnaces, they were very careful not to damage my floors and walls, and even laid out red carpeting to protect the floors. They were very friendly and professional. The installation was completed in the time they said it would take and they cleaned up their work areas. Within a week, Dave called to follow-up to see how everything was going. I have already recommended them to several friends and family members who may need new furnaces soon.

Twintech did a great job, from Dave the Sales Rep to the Office staff and The Professional Technicians who did the installation. They were professional, courteous, knowledgable and informative. From beginning to follow up we were completely satisfied with everything. Thanks Again. Sincerely The Laytons

Great product, great service, great follow-up. The Twintech Heating and Cooling arranged removal of my existing oil tank and they installed the new gas furnace Amana (made in USA). I am very happy with the final result and support I received throughout the process. My thanks go to the entire Twintech team for their professionalism, great communication and follow-up.
May 4, 2020
We've had Twintech provide us with work in the past, for an inground pool heater and required rough-in for a new gas stove. More recently they provided the same friendly, professional, timely and clean installation of our new furnace.
