Why Cold-Climate Heat Pumps Excel in Ontario Winters

Ontario winters are known for their freezing temperatures, icy winds, and long stretches of frigid weather.
For decades, many homeowners assumed that heat pumps couldn’t handle this kind of climate.
But today’s cold-climate heat pumps are a different story.
Thanks to modern engineering and major efficiency improvements, they’re now one of the most effective, reliable, and energy-saving heating options for Ontario homes.
Here’s why cold-climate heat pumps excel during even the harshest Ontario winters.
1.
Engineered to Perform in Sub-Zero Temperatures
Older heat pumps struggled when temperatures dropped, but cold-climate models are specifically designed to maintain strong heating performance even in –20°C to –30°C weather.
They accomplish this with:
Advanced compressors that pull heat from outdoor air more efficiently
Enhanced refrigerants that remain effective at lower temperatures
Variable-speed technology that adapts to real-time conditions
This means your home stays warm without relying heavily on backup heating sources.
2.
Consistent Comfort Without Temperature Swings
Traditional furnaces turn on and off in cycles, which can create uneven temperatures.
Cold-climate heat pumps operate differently — they run continuously at lower speeds to keep your whole home consistently comfortable.
Benefits include:
Fewer cold spots
Steadier temperature control
Reduced noise
Less dryness compared to gas heating
This balanced comfort is especially noticeable in older homes or multi-level layouts.
3.
Major Energy Savings All Winter Long
Cold-climate heat pumps are extremely efficient because they move heat instead of generating it.
Even in freezing weather, they can produce two to three times the heat for each unit of electricity consumed.
This can lead to:
Lower winter heating bills
Reduced reliance on expensive electrical resistance heat
A smaller environmental footprint
With energy prices rising across Ontario, these savings make a real difference.
4.
Smart Defrost Technology Keeps Efficiency High
Ontario winters bring snow, ice, and frost — all of which can affect HVAC performance.
Cold-climate heat pumps use intelligent defrost controls that activate only when necessary.
This prevents:
Excess energy waste
Ice buildup on outdoor units
Performance drops during cold snaps
Your system stays efficient and reliable throughout the season.
5.
Perfect for Hybrid Heating Systems
For homeowners who already have a gas furnace, a cold-climate heat pump can work in dual-fuel (hybrid) mode.
This setup automatically chooses the most efficient heat source based on outdoor temperature.
Advantages include:
Optimized energy use
Lower gas consumption
Reliable comfort during extreme cold
Better long-term savings
Hybrid systems offer the best of both worlds — efficiency and backup peace of mind.
6.
Environmentally Friendly Heating
Cold-climate heat pumps produce significantly fewer emissions than fossil-fuel systems, helping reduce your home’s carbon footprint.
As Ontario’s electricity grid continues to get greener, the environmental benefits of heat pumps will only grow.
7.
Year-Round Comfort from One System
One of the biggest advantages? Your heat pump doesn’t just heat — it cools your home in summer, replacing the need for a separate air conditioner.
This simplifies maintenance, reduces equipment costs, and keeps your home comfortable throughout all four seasons.

On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

Twin tech team was very efficient and prompt. They provided a quote within hours of request and got the job done on time. No disruption to home function. We would highly recommend this team. Job well done.
Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.
Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.
The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.
We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.
Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.
Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.
This is a professional team that's easy to deal with. I would strongly recommend them
Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!
Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!

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!
