Avoid classic mistakes when buying an air conditioner, based on our field experience in Longueuil.
In the world of HVAC residential systems, we’ve noticed that many homeowners in Longueuil and surrounding areas end up with an air conditioning system that is unsuitable, inefficient, or improperly installed. Often, these mistakes aren’t due to a lack of interest but stem from misplaced trust in overzealous or undertrained salespeople. At AirGreen, we believe that an informed choice always starts with understanding the real questions to ask.
Understand Your Real Needs Before You Buy
What salespeople don’t always consider
During our visits in Longueuil, we often see wall-mounted air conditioners or central heat pumps that are either undersized or poorly placed. Why? Because customers are often recommended a generic model based only on square footage, without considering:
-
The level of insulation in the home
-
The sun exposure (especially homes facing south)
-
The number of windows, and their exposure
-
Vaulted ceilings, mezzanines, or open floors
A home in Vieux-Longueuil with large windows isn’t going to behave the same as a bungalow in Saint-Hubert. This is where our on-the-ground expertise makes all the difference.
Real-life example: Poor recommendation from a salesperson
A customer in Greenfield Park recently called us to replace a 12,000 BTU heat pump installed a year earlier. The unit never reached the desired temperature. After our evaluation, we recommended an 18,000 BTU heat pump with high energy efficiency ratings, featuring a SEER of 21, better suited to the actual environment of the home. Since then, comfort has been restored, with energy savings to boot.
How to Recognize a Good HVAC Salesperson in Longueuil?
1. They visit the site BEFORE giving you a quote
A salesperson who offers you an installation without visiting your home misses a key point: understanding the building. We always perform a free on-site evaluation, which includes:
-
Analyzing the air volume to be conditioned
-
Calculating the clearance needed for the outdoor unit
-
Checking access for pipe routing
-
Identifying potential noise sources to avoid any nuisance
2. They talk to you about ventilation, not just air conditioning
An efficient air conditioner is inseparable from proper air renewal. If a salesperson doesn’t mention the need for an HRV air exchanger in your airtight home, that’s a red flag. A good HVAC system is a coherent whole, not just a machine.
3. They know about grants available in Longueuil
We always incorporate financial assistance available from programs like LogisVert by Hydro-Québec in our recommendations. A customer in LeMoyne was able to secure $1,704 in grant money for their new Gree Extreme wall-mounted heat pump, installed by our team.
Common Mistakes to Avoid When Buying an Air Conditioner
-
Believing a bigger unit is always more efficient
-
Choosing based solely on the lowest price
-
Overlooking energy consumption (SEER/HSPF)
-
Forgetting to ask about warranty and after-sales service
-
Not checking whether the installer is certified (RBQ, TEQ)
Why Proper Sizing is Crucial
A too-small unit will always be overworked, prematurely wearing out its components. A too-large unit will create short cycles, which harms the dehumidification of the air and causes uncomfortable dry, cold sensations. In Longueuil, where temperature fluctuations can be significant, the right balance is essential.
