A Frosty Week to Better Understand the Challenges of Winter Heating in Montreal
In Montreal, a city known for its long and harsh winters, imagining a single day without heating seems unthinkable. However, at AirGreen, specialists in HVAC (heating, ventilation, and air conditioning), we wanted to push this experience to the extreme by living without any heating system for a full week in order to illustrate the critical importance of an efficient and reliable heating system during a Quebec winter. Here is the authentic and detailed account of this icy adventure, along with the valuable lessons learned from the experience.
Day 1: Initial Anticipation and Optimism
At the beginning of this unusual experiment, our HVAC expert settled into a typical house located in the Rosemont–La Petite-Patrie neighborhood, without any active heating source. The idea was simple: to understand the real effects of intense cold on daily life, and to better understand the specific needs of our clients in Montreal, Laval, Longueuil, the North Shore, and the South Shore.
The first few hours seemed bearable, but as night fell, the harsh reality set in. With the outdoor temperature hovering around -15°C, the indoor temperature dropped quickly, immediately highlighting the importance of an efficient heat pump or reversible wall-mounted air conditioner that can maintain a comfortable indoor climate even in extreme cold.
Day 2 to 3: First Signs of Discomfort and the Real Challenges Begin
After the first difficult night, our expert recorded an indoor temperature of only 7°C by morning. At this point, every daily task became a struggle: showering, preparing meals, or simply staying focused on work. During these cold days, the body began to strongly feel the discomfort of prolonged exposure to low temperatures, which allowed us to understand in depth the challenges faced by residents without functional or high-performing heating systems.
During this period, it became clear that choosing an adequate heating system, whether it’s a high-quality wall-mounted heat pump such as models from Fujitsu, Gree, or Lennox, is not simply about comfort, but an absolute necessity in Montreal. These solutions not only ensure consistent warmth but also provide access to government subsidies (such as the Chauffez Vert program) that make acquiring energy-efficient, sustainable equipment more accessible.
Day 4 to 5: Physical Struggles and the Revelation of Thermal Inefficiencies in the Home
By mid-week, the physical effects of the cold had intensified drastically: constant shivering, numbness, and difficulty maintaining productivity. This situation highlighted the structural and thermal weaknesses of the tested home. The inadequate insulation of windows and walls, especially in older Montreal homes, exacerbated the heat loss, clearly revealing the critical areas that need to be addressed to maximize energy efficiency.
During this phase of the experience, the importance of a comprehensive energy audit performed by our teams at AirGreen became even more apparent. Our recent projects in Longueuil and Laval clearly demonstrate that installing a wall-mounted heat pump or a high-performance central heat pump system must always be accompanied by a thorough inspection of the building’s thermal insulation to ensure maximum efficiency.
Day 6: Deep Reflections on the Importance of Professional HVAC Installation
As the week drew to a close, our expert had a major revelation: living without heating in winter in Montreal is not only uncomfortable, but it can also become dangerous to your health. Temperatures below 10°C for extended periods can weaken the immune system and significantly reduce quality of life. This reinforced the critical importance of trusting HVAC installations to qualified experts like our technicians at AirGreen, who can recommend equipment precisely tailored to local climatic conditions.
Our recent experiences with projects in Longueuil and Laval clearly show how professional and well-suited installations (Gree, Lennox, Fujitsu heat pumps, central or wall-mounted systems) can radically transform the thermal comfort of a home, even during the coldest times of the year.
Day 7: Return to Comfort and Essential Lessons Learned
Finally, at the end of this challenging week, the activation of the heating system (a Fujitsu wall-mounted heat pump with 18,000 BTU and R-32 refrigerant, eligible for local subsidies) was a true relief, both physically and mentally. The immediate and striking difference felt when the interior temperature returned to 21°C demonstrated the vital importance of a reliable and efficient HVAC system.
This return to comfort also highlighted the importance of regular maintenance carried out by our specialized teams to avoid any unexpected failures during the most critical periods of the year.
Conclusion: Efficient Heating, an Absolute Necessity in Montreal
This unique experience undeniably demonstrates that the quality of heating in Montreal is never optional but an absolute necessity. At AirGreen, we now have a deeper understanding of the critical importance of accompanying every installation with expert advice, a rigorous selection of equipment, and regular maintenance to ensure optimal thermal comfort, year after year.
