Extreme Heatwave in Laval: How to Avoid an AC Breakdown at the Worst Possible Time

Extreme heatwaves are hitting Laval more and more frequently, turning Quebec summers into intense, scorching episodes. For residents, an air conditioning failure during a heatwave isn’t just uncomfortable – it can become a serious health concern, especially for the elderly, children, or people with medical conditions. At AirGreen, we know that avoiding breakdowns at the worst possible time requires a proactive, technical, and tailored approach. Here’s our on-the-ground expertise, our know-how in wall-mounted air conditioning, and the concrete solutions we implement to protect our Laval clients from system failures during peak periods.

Why do air conditioners break down during heatwaves?

Residential and commercial air conditioning systems are put under heavy strain during heat peaks. A combination of several factors can cause a breakdown at the worst time:

• Compressor overload, having to run non-stop to maintain a stable temperature.

• Clogged filters, restricting airflow and forcing the system to work harder.

• Low refrigerant levels or slow leaks that go undetected.

• Neglected maintenance, with dust, mold or dirt buildup on coils.

• Improper installation, poorly sized or poorly ventilated.

• Local power outages, common when an entire neighborhood overloads the grid.

AirGreen Installation in Laval: A Concrete Example of Preventive Intervention

A few weeks ago, we were contacted by a family in Vimont, Laval, concerned about the decreasing performance of their old wall-mounted unit ahead of upcoming heatwaves. After a thorough diagnosis, our team recommended a new installation of a Gree Lomo 2nd Generation 18,000 BTU wall-mounted air conditioner, perfectly suited to the configuration of their single-family home and Laval’s climate.

Key steps of our intervention:

1. Precise thermal analysis of the home, including orientation, number of windows, insulation materials.

2. Selection of the right Gree Lomo model, known for its reliability, moderate energy consumption (SEER 20, HSPF 10.5), and quiet operation.

3. One-day installation, including secure wall mounting, optimized condensate drainage, and proper refrigerant line calibration.

4. Full system startup, with pressure tests, leak detection, and electronic regulation calibration.

5. Clear explanation to the client about maintenance cycles, smart remote use, and early warning signs of an issue.

This Laval family now enjoys a stable system, highly efficient even on days above 33°C, and, most importantly, covered by a comprehensive 10-year parts and labor warranty.

What can you do to avoid a breakdown at the worst time?

Schedule a professional annual maintenance

We strongly recommend a full HVAC maintenance before the hot season. At AirGreen, this includes:

• Cleaning of both indoor and outdoor coils

• Refrigerant level check

• Inspection of fan and motor

• Pressure and airflow test

• Thermostat calibration

An annual maintenance extends your AC’s lifespan and helps detect issues before they cause a breakdown.

Choose an installation suited to your space

Many clients call us after having a bad experience with a unit that was oversized or undersized. An overly powerful unit wears out quickly due to short cycles. An underpowered unit overheats and breaks down faster. At AirGreen, we take the time to evaluate your real needs before every installation.

Stick to proven brands and proper BTU sizing

We work with reliable brands like Fujitsu, Gree, Sharp, Bosch, and Daikin. In Laval, for an average home (1,200 to 1,500 sq. ft.), a wall unit between 12,000 and 18,000 BTU is generally ideal – but we always assess each case individually.

Watch for early warning signs

Before a breakdown, your AC often gives subtle signs:

• Reduced efficiency or longer time to cool a room

• Unusual noises (vibrations, clicking)

• Air not as cold as usual

• Excess condensation or water leaks

At the first sign of trouble, contact our team immediately for a fast inspection.
