A question we often hear from our clients in Longueuil, and elsewhere on the South Shore, is this: Is air conditioning truly harmful to the environment? At AirGreen, a company specializing in air conditioning and HVAC systems in the Greater Montreal area, we understand how valid these concerns are. Between misinformation, common misconceptions, and scientific facts, it’s time to take a closer look at the environmental impact of air conditioning systems, especially as demand for wall-mounted heat pumps, central air conditioners, and energy-efficient solutions continues to surge.
Growing demand, but better regulated
Air conditioners, once considered a luxury for a privileged few, have now become an essential part of modern comfort, especially in Longueuil, where summers are increasingly hot and humid. This democratization naturally raises environmental questions. But contrary to popular belief, air conditioning technology has evolved significantly, and today’s systems are far more environmentally friendly than those of 10 or 20 years ago.
Myth #1: All air conditioners release harmful gases into the atmosphere
This myth mostly stems from older generations of equipment that used freon gases (CFCs and HCFCs), which were extremely damaging to the ozone layer. But legislation has changed drastically. Manufacturers like Fujitsu, Gree, Goodman, and Bosch now use low Global Warming Potential (GWP) refrigerants like R-32 or R-454B.
At AirGreen, we install only units that are compliant with the strictest environmental standards, like the FUJITSU KZAH R-32 wall-mounted heat pump or the Bosch BOVA R-454B central system, specifically designed to reduce environmental impact while delivering top-tier performance.
Myth #2: Air conditioning uses too much energy
It’s true that some older models could double a household’s energy bill. But Inverter technologies and high-efficiency heat pumps have changed the game. For example, a typical installation of a Bosch BIVA IDS Premium central heat pump in Longueuil, done by our team, allows the homeowner to cool and heat their home while reducing annual energy consumption by up to 40%.
Even better, these systems are eligible for rebates under Hydro-Québec’s LogisVert program, making them even more attractive for residents of Longueuil while promoting sustainable practices.
Myth #3: Modern air conditioners are all the same
Nothing could be further from the truth. Every building—be it a plex in Vieux-Longueuil, a bungalow on Béliveau Street, or a condo near Longueuil–Université-de-Sherbrooke metro station—comes with unique technical challenges. Our team always performs a complete thermal evaluation to recommend the most suitable system for the customer’s real needs, in terms of both performance and environmental impact.
Case Study in Longueuil: A smart heat pump installation to reduce carbon footprint
Recently, we installed an 18,000 BTU GREE EXTREME wall-mounted heat pump in a bungalow near Parc Michel-Chartrand. The customer was looking for a cooling solution for the summer, but also a system that could efficiently heat during -25 °C winters, while minimizing their carbon footprint.
Thanks to our expertise, we selected the ideal model with R-32 refrigerant, a SEER of 25, and an HSPF over 10. The result? Optimal year-round comfort, reduced energy bills, and a $1,704 LogisVert rebate to top it off.
What you can do to choose an eco-friendly air conditioning system
1. Choose an energy-efficient system
Look for models with a high SEER (cooling efficiency) and a strong HSPF (heating efficiency). At AirGreen, we recommend the best Energy Star-certified options.
2. Demand low-GWP refrigerants
Refrigerants like R-32 and R-454B are now a must. We use them systematically in all our new installations across the South Shore.
3. Work with a certified installer
A poor installation can ruin the benefits of a high-performing system. Our certified technicians understand all environmental standards and guarantee an optimal setup, both technically and ecologically.
