Cold-Climate Heat Pumps Explained
Posted On: February 2, 2026
If you’ve heard that heat pumps don’t work in cold weather, you’re not alone.
That used to be true.
Today’s cold-climate heat pumps are designed specifically to handle freezing temperatures—and they’re becoming one of the most efficient heating options for homes in cold regions.
At Twintech Heating & Cooling, we install and sell modern cold-climate heat pumps, and homeowners are often surprised by how well they perform—even during harsh winters.
Let’s break it down.
What Is a Cold-Climate Heat Pump?
A cold-climate heat pump is a high-efficiency heating and cooling system engineered to operate in temperatures well below freezing, depending on the model.
Instead of generating heat by burning fuel, a heat pump:
Pulls heat from the outside air (yes, even cold air contains heat)
Compresses and transfers that heat indoors
Reverses in summer to provide air conditioning
Cold-climate models use:
Advanced inverter-driven compressors
Enhanced refrigerants
Improved defrost cycles to maintain consistent heat in winter.
Do Heat Pumps Really Work in Cold Weather?
Yes—when you install the right system for the climate.
Older heat pumps struggled below certain temperatures.
Modern cold-climate heat pumps are specifically designed for winter performance and can:
Maintain indoor comfort in sub-zero temperatures
Deliver steady heat without temperature swings
Operate far more efficiently than electric resistance heat
In many homes, they can replace a traditional furnace—or work alongside one in a dual-fuel setup.
Heat Pump vs Furnace in Cold Climates
Here’s how cold-climate heat pumps compare to traditional systems: Heat Pumps
Extremely energy efficient
Lower operating costs
Provide both heating and cooling
Reduce reliance on fossil fuels Furnaces
Very strong heat output in extreme cold
Often paired with heat pumps for backup
Higher fuel costs over time
Many homeowners choose a dual-fuel system, where the heat pump handles most heating, and a furnace kicks in only during extreme cold.
What About Ice and Defrost Cycles?
You may notice frost on the outdoor unit in winter—that’s normal.
Cold-climate heat pumps use automatic defrost cycles to:
Melt ice buildup safely
Maintain heating performance
Prevent damage to the system
A properly installed heat pump will manage this seamlessly without affecting indoor comfort.
Are Cold-Climate Heat Pumps Worth It?
For many homeowners, absolutely.
Benefits include:
Lower monthly energy bills
Fewer mechanical parts than combustion systems
Quiet operation
Long system lifespan
Possible rebates and incentives
The key is professional sizing and installation.
An undersized or improperly installed system won’t perform as intended.
Is a Cold-Climate Heat Pump Right for Your Home?
Cold-climate heat pumps are ideal for:
Homes with moderate to good insulation
Homeowners looking to reduce energy costs
Properties replacing older furnaces or AC units
New installations or system upgrades
At Twintech Heating & Cooling, we evaluate your home, climate needs, and comfort goals to recommend the right heat pump system—not a one-size-fits-all solution.
Professional Heat Pump Installation Matters
Performance depends heavily on:
Correct system sizing
Proper refrigerant charge
Smart thermostat integration
Quality installation
That’s why working with an experienced HVAC contractor is critical.

Great service and great people to deal with, from sales to installer. I highly recommend this company.

Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!

We wanted to get our AC replaced as it was 22-years old and added to this our furnace was costing more and more to repair. So, we decided to get both the furnace and AC replaced.
After going through a few quotes and product reviews we decided to go with Twintech. The three-men crew arrived early in the morning, wasted no time and got to work right away. By 2:00 pm, they were all done. Ive found their work to be top notch and they were completely professional. I had all my questions answered to my satisfaction both during the progress of their work and at end.
I have pleasure in recommending Twintech to anyone who is looking to get their furnace or Ac replaced

Our air conditioner died On a Saturday and within hours Dave came out to take a look and discuss replacement/repair options.
The new air conditioner was installed on the Wednesday. The new unit was installed quickly. The installers were friendly and cleaned up afterwards.
We noticed a slight leak around the furnace that night and they came out the next day and fixed the issue. It has been working great and is quieter than our previous unit.
Very satisfied and would highly recommend TwinTech.

I contacted TwinTech to replace my 20-year old A/C. Dave, their service rep, promptly replied and was at my home within 2 hours. He was friendly and knowledgeable and didn't try to upgrade or oversell their A/C units but suggested the best fit for my small 1000 feet bungalow. Although this was during a heatwave and very busy, they were able to fit me in 2 days later. The TwinTech crew installed a 1.5 ton Ducane A/C unit that is now running smoothly while maintaining a constant cooling temperature. The crew were very courteous, professional and efficient and I will definitely recommend TwinTech to family and friends. I much appreciated your great service.

Professional, courteous and efficient, dont need to say more than that! Use them you will not regret it.

TwinTech was a pleasure to deal with from the estimate through installation. We replaced a 28 year old a/c unit with one recommended by TwinTech's sales representative Dave who took the time to go over the product with us and answer any questions. The warranty is for 10 years parts and labour and they will complete the registration for you. Installation was by Greg (owner) and Mitch and Spencer who were quick and efficient and left everything clean and tidy.

Very professional, from the sales consultation and inspection to the final installation. Met every expectations we had for the job. A local business with great client support. We highly recommend. Twintech is a blue chip! Thanks!
