Clean, fresh, and high-quality indoor air is essential—especially during summer when temperatures soar and the air conditioning is running full blast. At AirGreen, we know that a proper air conditioning installation isn’t just about cooling a room: it also plays a key role in the health and well-being of everyone inside. Whether you're in Montréal, Laval, Longueuil, on the North Shore or the South Shore, here are our 7 expert tips to maximize comfort, air quality, and your air conditioning system’s performance all summer long.
Regular HVAC Maintenance: The Foundation of Clean Indoor Air
The first essential step, often overlooked, is the regular maintenance of your HVAC system. A wall-mounted heat pump or air conditioner that isn’t properly maintained can become a breeding ground for bacteria, mold, and dust.
-
Clogged filters = poor air quality + lower efficiency
-
Dirty ducts = spread of particles and allergens
At AirGreen, we recommend professional cleaning at least once a year, ideally in the spring, to ensure healthy air conditioning throughout the summer. Our technicians respond quickly in Montréal, Laval, and surrounding areas for full maintenance service—cleaning filters, coils, fans, and more.
Use an Air Conditioning System with Advanced Filtration
Technology has come a long way: many modern models, like Gree, Fujitsu, or Sharp wall-mounted air conditioners, come with HEPA filters, activated carbon filters, or even ionization systems. These features help trap:
-
Fine particles (PM2.5)
-
Volatile organic compounds (VOCs)
-
Bacteria and viruses
If you're sensitive to allergens or have children or seniors at home, choosing an air conditioner with air purification technology is a smart investment in your health.
Don’t Undersize or Oversize Your System
The efficiency of an air conditioner doesn’t just depend on the brand or model—it mainly depends on correct sizing.
-
A unit that’s too small will overwork, wear out faster, and filter air poorly.
-
A unit that’s too large will cool too quickly without properly dehumidifying the air.
At AirGreen, every installation project starts with a comprehensive thermal analysis. We consider your home’s orientation, window surface, insulation, and your living habits. This ensures a powerful, efficient, and long-lasting air conditioning setup.
Maintain Ideal Indoor Humidity
In summer, excess humidity can lead to mold, dust mites, and discomfort. Your air conditioner should cool AND dehumidify effectively. Here’s what we recommend:
-
Aim for indoor humidity between 40 and 60%.
-
Choose air conditioning units with an independent dehumidification mode.
-
If needed, add a standalone dehumidifier in risk areas (basement, bathroom).
Several models we install in Longueuil, like the Fujitsu KZAH R-32, offer excellent humidity control thanks to Inverter technology and advanced sensors.
Ventilate Smartly, Even During Heatwaves
Many people think you should never open windows when the AC is on. That’s only partly true: during peak heat, it’s best to limit hot outdoor air entering. However, targeted daily ventilation, early morning or late evening, helps renew indoor air and remove pollutants.
Our experts also recommend installing air exchangers (like the Venmar AVS), especially in well-insulated or renovated homes. We regularly install these systems in Blainville, Saint-Bruno, and Laval, integrated with existing HVAC systems.
Avoid Indoor Sources of Pollution
For cleaner indoor air, limit use of chemical products such as:
-
Scented candles
-
Air fresheners
-
Harsh cleaning products
Choose natural alternatives, ventilate well after use, and make sure your air conditioner circulates air efficiently throughout all rooms. A ceiling fan can help improve airflow as a complement to your system.
Choose a Certified and Professional HVAC Installation
In the end, nothing replaces a professional installation. A poor setup can cause:
-
Refrigerant leaks
-
Strange noises
-
Uneven air distribution
-
Early equipment failure
At AirGreen, every project is carried out by certified, experienced technicians who truly care. We also provide follow-up after installation to ensure optimal performance, answer your questions, and guide you through available grant programs (Hydro-Québec’s LogisVert, Canada Greener Homes, etc.).
We recently completed a full installation of a Gree Extreme 18,000 BTU wall-mounted air conditioner in Sainte-Julie (South Shore). This model, eligible for a $1,704 grant, delivers exceptional air quality thanks to its multi-stage filtration system, all while cooling quickly and quietly.
