Optimizing Your Air Conditioning in Longueuil: The Golden Rules Based on Our Real-World Expertise
At AirGreen, we know that thermal comfort during Longueuil summers depends on air conditioning that is well thought-out, well installed, and well maintained. After hundreds of successful installations across the South Shore, we’ve identified essential principles to follow in order to ensure wall-mounted air conditioners or heat pumps that are efficient, long-lasting, and energy-saving. These golden rules, drawn from real-life cases, have become our go-to guide for both residential and commercial clients.
1. Choose a heat pump or wall-mounted AC suited to Longueuil’s climate
Longueuil summers are increasingly hot and humid. So it’s crucial to choose a wall-mounted heat pump or air conditioner with the right BTU output, based on the surface area, sunlight exposure, and insulation of your building.
Real example: During a recent installation in a duplex in Vieux-Longueuil, we opted for an 18,000 BTU Fujitsu KZAH wall-mounted heat pump, ideal for a 950 sq. ft. open-concept space with large south-facing windows. This technical decision provided stable and comfortable temperatures, even during heatwaves.
2. Never underestimate the importance of proper installation
A top-quality unit installed poorly can turn into an energy nightmare. At AirGreen, our certified technicians follow strict protocols to ensure the installation is perfect from the very first visit.
In the Saint-Hubert neighborhood, we recently replaced an old, poorly installed unit with a Gree Lomo wall-mounted air conditioner. The result: an immediate 30% drop in electricity consumption and much better humidity control.
3. Always prioritize energy efficiency
Modern units offer much higher performance ratings (SEER and HSPF), translating into noticeable savings on your electricity bill.
For instance, the Bosch BIVA IDS Premium wall-mounted heat pump, very popular in Longueuil, boasts a SEER over 20 and is eligible for the LogisVert grant of $1,860 from Hydro-Québec.
4. Check grant eligibility before you buy
Many financial incentives are available for Longueuil residents. AirGreen provides free support with the application process. A good eligible unit can cost you significantly less.
One of our clients in Lemoyne recently received a LogisVert grant of $1,704 for installing an 18,000 BTU Gree Extreme wall-mounted heat pump, covering over 40% of the total cost.
5. Maintain your unit regularly
An annual maintenance extends your system’s lifespan and prevents costly breakdowns.
Our teams offer a full service of cleaning, disinfection, and duct inspection, which is in high demand in Longueuil, especially in neighborhoods like Fatima and Pierre-Boucher.
6. Install in the right location—indoors and outdoors
The position of the indoor unit directly affects air distribution. The outdoor unit should be installed in a shady, snow-protected spot, ideally on a raised wall-mounted bracket.
In Greenfield Park, we resolved a customer’s noise and overheating issue simply by moving the outdoor unit by one meter, away from a sun-exposed metal wall.
7. Schedule winter maintenance, even for a summer-only unit
Even if your system isn’t used for heating, it can still get clogged or covered in snow. A preventive check-up in spring is highly recommended.
We offer personalized HVAC maintenance plans to Longueuil homeowners to ensure optimal performance once the heat returns.
8. Think about your home’s overall insulation
Efficient air conditioning starts with a well-insulated home. We often recommend an energy audit to detect sources of heat (or cool) loss.
In Longueuil, several clients were able to downsize their heat pump needs after adding attic insulation and replacing windows.
9. Choose a certified local HVAC installer
Working with a local expert like AirGreen means having someone who understands local weather conditions and municipal regulations. It also guarantees quick response and availability for after-sales service.
Our technicians are on call 7 days a week across all of Longueuil, from Boucherville to Saint-Hubert.
10. Think long-term, not just about the price
A cheap wall-mounted unit may seem like a good deal, but a shorter lifespan, frequent breakdowns, and low efficiency can cost you much more over time.
We always recommend trusted brands like Fujitsu, Gree, Bosch, or Goodman, which combine performance, reliability, and long-term savings.
An AirGreen Installation is a Long-Term Investment in Your Comfort
Every project we take on in Longueuil is treated as a fully customized job. Our experts consider all factors: surface area, sun exposure, budget, available grants, cooling and heating needs, and more. We never install a unit without analyzing the complete picture first.
Real Case: A Bosch Wall-Mounted AC in Longueuil
We recently installed a 24,000 BTU Bosch BOVA in a townhouse on Préfontaine Street. Thanks to its ultra-quiet performance, the customer now cools both floors without any noise disturbances, even at night. Plus, the LogisVert grant covered nearly 25% of the investment.
