Quebec heat waves can hit hard and fast. If your air conditioning isn't ready, you risk a breakdown at the worst moment. Here's how to prepare your cooling system before intense heat arrives.
Don't Wait for the First Hot Day
HVAC technicians are extremely busy during the first heat waves. Prepare your system in May or early June to avoid wait times.
7 Steps to Prepare Your Air Conditioning
Clean filters are the foundation of an efficient system. A clogged filter can reduce airflow by 15 to 20% and force the compressor to overheat. Replace them before the season.
After winter, vegetation may have grown around the unit. Trim shrubs, remove leaves and ensure 24 inches of clearance all around for proper airflow.
Damaged or poorly insulated ducts can lose up to 30% of cooling capacity. Check for leaks, holes or tears in insulation.
Don't wait for the first 35°C day to test your AC. Turn it on a week early to detect any performance issues.
A system with insufficient refrigerant cannot cool effectively. This check must be performed by a certified technician (regulated handling).
Program your thermostat to start cooling before you return home. Avoid extreme temperature swings that overwork the compressor.
A pre-summer preventive maintenance visit includes checking all components, coil cleaning and performance optimization. It's the best investment for a worry-free summer.
A well-maintained system consumes up to 25% less energy
Heat Pump vs Traditional Air Conditioner
If you're looking to replace your old AC before summer, consider a heat pump. It cools just as effectively as a traditional air conditioner but also provides heating down to -30°C. With Hydro-Québec and Rénoclimat subsidies available, the cost difference is often minimal.
💡 CHAUFROI Tip
Install a windbreak or awning to protect your outdoor unit from direct sunlight. A compressor in the shade can be up to 10% more efficient.
