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.

Appreciated a quick response to my request. Dave and Greg were very professional and made the experience seamless.
Very professional through the entire process. Installation and removel was done on a sloppy winter day, they put down runners on the floors and stairs and when they left, there wasn;t any sign of someone being in our house. Furnace works great as promised.
Dave was very pleasant to deal with and Twintech responded quickly when our furnace needed to be replaced ASAP. Installation was done on time and the crew were neat and tidy. We now have a great furnace that suits the needs of our family.
When your furnace kicks in over the holidays and you're not sure where to turn.. I'm so thankful that this company returned my phone call. I appreciated their transparency and clarity which allowed me to make an informed decision. With various quotes thrown at you, it can be difficult to make the right decision and trust the solutions offered by different companies. TwinTech spoke the truth and delivered on their word. Neat, timely and clean service; the peace of mind I needed during a very cold holiday season. I highly recommend them!
Pulling a old unit out and installing a modern heating system! Required drilling holes in the wall for the newer pipes. We went from 70% (I am willing to bet it was far less due to lack of maintenance and just old) to 96% newer . It now feels warmer and more pressure and we use to run extra heaters and feel as though they are not necessary!
I received three quotes before deciding to choose Twintech. Dave's prices was much more reasonable than the competitors. I most appreciated their honest recommendations. Others tried to oversell their products and services. Thank you Dave!
They had the best price and did a great job on the installation. Recommend them to anyone.
It was a amazing and professional high quality job
Friendly and very helpful representatives
Thank you for understanding my concern
And explain very well
Overall we pleased with your service

My 19 year old furnace stopped working when the cold weather hit in November, and I was left without heat. I interviewed several companies and found TWINTECH HEATING and COOLING to be very knowledgeable, quick to respond to my inquiries and very competitively priced.
Dave provided all of the information and pricing ahead of time and set up the appointment for the installation. Greg and Mitch arrived on time to do the installation and worked quickly and efficiently to complete the job.
After the completion of the installation, Dave followed up to ensure that everything was working well and that I didn't have any concerns.
Overall, this was a low-stress and flawless experience from start to finish. I would highly recommend TWINTECH HEATING and COOLING to anyone that requires a new furnace.
Our 20 year old furnace broke down during the first cold weekend this past November and our usual HVAC company never returned our phone call. Their loss, missing out on a sale since we didn't want to spend much fixing an old furnace and our 40 year old air conditioner was also long overdue for replacement. We proceeded in obtaining three different quotes for furnace and air conditioner replacement, and proceeded with the one we received from Twintech.
Dave was friendly, knowledgable and accommodating to our schedule and provided with us with a price that fell in the middle of the three quotes that we had. We felt that the Amana furnace and air conditioner he quoted us on were the best products and value offered to us and felt most comfortable with the professionalism and reputation of Twintech.
Greg, Grant and Mitch were at our house for installation the day after we decided to proceed. The guys were friendly and informative, the job was completed efficiently and workmanship appears excellent. Our house is certainly much more comfortable with the new two-stage variable speed Amana furnace compared to the old clunker! And, we're looking forward to enjoying the new air conditioner once summer rolls around again. Thanks 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.

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!
