Modern cold-climate air-source heat pump operating in snowy Quebec winter conditions

What Is a Cold Climate Air-Source Heat Pump and Why Is It the #1 Choice for Quebec?

A Cold Climate Air-Source Heat Pump (CCASHP) is a next-generation HVAC system specifically engineered to extract heat from frigid outdoor air — even when temperatures fall below -25°C or -30°C. Unlike traditional heat pumps that struggle or shut down in deep cold, CCASHPs use advanced technologies like variable-speed inverters, enhanced refrigerants (R-410A or R-32), and intelligent defrost cycles to maintain peak efficiency and continuous comfort throughout Quebec’s harshest winters.

For decades, Quebec homeowners relied on furnaces because standard heat pumps couldn’t handle the cold. That’s no longer true. Modern CCASHPs, such as those from Mitsubishi, Daikin, and Fujitsu, now provide up to 80–90% of a home’s annual heating needs — eliminating the need for fossil fuels entirely. They’re also incredibly efficient in summer, providing quiet, dehumidified cooling. With federal and provincial rebates covering up to $5,000, switching to a CCASHP isn’t just smart — it’s one of the best financial decisions you can make for your home. Plus, by removing combustion, you eliminate carbon monoxide risks and dramatically improve indoor air quality.

Choosing a Cold Climate Air-Source Heat Pump means choosing freedom — from fuel deliveries, high bills, and outdated systems. It means embracing clean, reliable, and future-proof comfort designed specifically for Quebec. Let Thermopompe Montréal install the right CCASHP for your home — no matter how cold it gets.

Customer Training & Seasonal Follow-Up

We show you how to operate your system, explain winter maintenance tips (e.g., keeping snow off the outdoor unit), and schedule a spring check-up to ensure peak performance through the next season.

Your Concerns, Our Solutions: Common Questions About Cold Climate Heat Pumps

We answer the top concerns Quebec homeowners have before switching to a modern, all-electric heating system.

💸

Is it really effective in -25°C or colder?

Yes. Modern CCASHPs are tested and certified to operate efficiently down to -30°C. Brands like Mitsubishi Hyper Heating and Daikin Altherma have proven performance records in Northern Canada and Scandinavia — places colder than Quebec.

🛠️

Do I still need my furnace?

Not anymore. Most homes can eliminate their furnace completely. In rare cases — like very large, poorly insulated homes — a small backup may be recommended, but 95% of our installations replace the furnace entirely.

🔊

Will it be noisy in winter?

No. Modern units feature sound-dampening technology and variable-speed compressors that run quietly even in cold weather. You’ll hear less noise than a traditional furnace ignition.

⏳

How long do these systems last?

With professional installation and annual maintenance, CCASHPs last 15–20 years — comparable to or longer than traditional furnaces. Many units from the early 2000s are still running today.

💡

Can I control it with my phone?

Absolutely. All our systems include Wi-Fi-enabled thermostats. Control temperature, view energy usage, receive alerts, and adjust settings from anywhere using your smartphone app.

💧

Does it handle humidity and condensation?

Yes. In winter, it prevents excess indoor humidity that causes condensation on windows. In summer, it dehumidifies effectively — reducing mold risk and improving comfort without overcooling.

Frequently Asked Questions About Cold Climate Air-Source Heat Pumps

Can a cold climate heat pump really replace my furnace in Quebec?

Yes — overwhelmingly so. Over 95% of our clients eliminate their furnace entirely. Modern CCASHPs are designed specifically for climates like ours and outperform older systems even in record cold snaps.

What’s the difference between a regular heat pump and a cold climate heat pump?

Standard heat pumps lose efficiency and often shut down below -5°C to -10°C. Cold climate models use advanced compressors, refrigerants, and defrost tech to operate efficiently down to -30°C — delivering full heat output when you need it most.

Are there rebates for replacing my furnace with a cold climate heat pump?

Yes! The Canada Greener Homes Grant offers up to $5,000 for replacing fossil-fuel heating systems with qualifying CCASHPs. Quebec’s Rénoclimat program adds additional incentives. We handle the entire application process for you.

How much does it cost to install?

Typical installation ranges from $8,000 to $15,000 depending on home size, unit model, and ductwork condition. After rebates, many customers pay only $5,000–$9,000 out-of-pocket — with monthly savings paying back the investment in 5–8 years.

Do I need to upgrade my electrical panel?

Sometimes. Most homes require a 200-amp panel. We assess your current panel during the consultation and advise if an upgrade is needed — often eligible for additional rebates.

Will snow or ice damage the outdoor unit?

No. Units are designed to withstand heavy snow and ice. We recommend keeping snow cleared from the front intake (about 2 feet) and installing the unit on an elevated, level pad to prevent ice buildup underneath.
