Heat Pump vs. Furnace: A Winter Breakdown for Ontario Homes
Posted On: December 8, 2025
When winter hits Ontario, reliable heating isn’t optional—it’s essential.
For decades, gas furnaces have been the default choice for cold weather comfort.
But modern cold-climate heat pumps are changing the conversation.
Thanks to major advancements in efficiency and performance, heat pumps now outperform furnaces in many key areas, especially when it comes to energy savings and overall comfort.
Here’s a winter breakdown of heat pumps vs.
furnaces—and why more Ontario homeowners are choosing heat pumps.
Heating Performance in Cold Weather
Winner: Heat Pumps
Today’s cold-climate heat pumps are engineered specifically for freezing temperatures and continue delivering dependable heat well below zero.
Unlike older models, modern systems maintain strong performance throughout most Ontario winters without relying heavily on backup heat.
Furnaces produce intense bursts of heat but cycle on and off frequently, which can lead to uneven indoor temperatures.
What homeowners notice with heat pumps:
More even warmth throughout the home
Fewer cold spots
Comfortable temperatures without extreme hot air blasts Winter Energy Efficiency
Winner: Heat Pumps
Furnaces create heat by burning fuel—this process is inherently less efficient.
Heat pumps simply move heat, allowing them to deliver significantly more heat energy than they consume.
Cold-climate heat pumps can produce two to three times more heat per unit of energy than many traditional heating systems, especially during milder winter days that make up much of Ontario’s heating season.
Monthly Heating Costs
Winner: Heat Pumps
Because they run more efficiently and at consistent speeds, heat pumps help lower winter heating bills.
Homeowners often see savings immediately compared to electric baseboards, older furnaces, or oil systems.
Hybrid heat pump systems maximize cost control by automatically switching to the most economical heat source based on outdoor temperature.
Comfort and Indoor Air Quality
Winner: Heat Pumps
Heat pumps deliver steady, gentle heat rather than sudden temperature spikes.
This reduces dry indoor air—a common complaint with furnace heating.
They also provide:
Continuous air circulation
Improved filtration
Less dust movement
The result is a more comfortable and breathable indoor environment throughout winter.
Maintenance and Reliability
Winner: Tie (Slight Edge to Heat Pumps)
Modern heat pumps are designed to operate continuously with less stress than furnaces that cycle frequently.
With proper maintenance, heat pumps often experience fewer mid-winter breakdowns and consistent performance.
Plus, one system handles both heating and cooling—reducing long-term service needs.
Environmental Impact
Winner: Heat Pumps
Furnaces rely on fossil fuels, producing direct emissions.
Heat pumps run on electricity and produce no on-site emissions, making them one of the most environmentally friendly heating solutions available.
As Ontario’s electrical grid becomes cleaner, heat pumps continue to grow even greener over time.
Long-Term Value
Winner: Heat Pumps
While upfront costs can be comparable, heat pumps typically deliver:
Lower annual energy costs
Fewer emissions
Reduced long-term operating expenses
Year-round heating and cooling in one system
When you factor in energy savings and potential incentives, heat pumps often offer better overall value than furnaces.
The Bottom Line: Heat Pumps Win Modern Ontario Winters
Furnaces still have their place, but cold-climate heat pumps have proven they’re more than capable of handling Ontario winters—often doing so more efficiently, comfortably, and affordably.
For homeowners in the Durham Region and Toronto, Twintech Heating & Cooling helps assess whether a heat pump or hybrid system is right for your home and heating needs.

Fantastic team. Completed the job as per the specifications and in under 3 hours. Highly recommended Twintech.

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.

Greg came over at 9:30pm to rescue my daughter and I from a horrible experience with Enercare that evening. He was professional. Kind. And got us what we needed quickly and at an afford price. I would 100% recommend calling on Greg and his team for any of your heating and cooling needs in the future!!

Installed a great hot water heater when our old one failed. When my furnace died during cold weather they showed up quickly and my house was warm before my wife got home. :)

I dont usually right reviews but when you receive service like this I felt it was a must. Honest and fair. I Have 4 children and on Xmas eve my furnace stopped working and a gentleman came out and got me up and running so at least we would have heat for the holidays. As promised he would replace my furnace early in the new year. The job was completed on time, great price for quality furnace and extremely clean and professional job. Would have never known anyone was in the house. Not a spec of dust or mess from lugging out an old rusty furnace. If you have any ac or heating concerns twintech is your only option. I was royally impressed with and Im sure you will be too.

This Company is terrific. No high pressure sales and they deliver exactly what they promise to deliver. The new furnace is great and we now get consistent temperatures throughout the house. The installers were great and very efficient and completed the work on schedule on the promised day. Everyone representing this company was very aware of their presence in our house and worked diligently to keep our home as uninterrupted and as clean as was humanly possible. We did not need to go around the house to clean up after they left, what a nice surprise. We have had follow up by the company to ensure everything is to our satisfaction. How unusual in today's environment. The impression left by Twintech is that they care about us and our home. This is so refreshing in today's high tech world. Out thanks go out to Dave in sales and G, G, and P (the installers).

Dec 23, 2018
The entire process was prompt and professional, from the initial quote to the installation of the new furnace. The team installed the new furnace and removed the old one in approx. 4 hrs. The guys were very knowledgeable and gave me lots of information. I have used Twintech before for a new A/C installation and new I was in good hands.

The overall experience dealing with this company was great from start to finish when getting a new furnace and ac this year. Everything was clearly explained to us during our consultation with Dave and there were no surprises with added costs. The work was done as expected and their response time to inquiries were very timely generally within a few hours or less. They are all very professional and was a pleasure to do business with them. Highly recommend to anyone looking for honest quality professional service.
