Getting your air conditioning system ready for summer isn’t just about pressing a button. At AirGreen, we believe that a high-performance cooling system starts long before the first heatwave. Behind every service call, every maintenance visit, and every seasonal startup, there’s a proven method, expert craftsmanship, and meticulous attention to detail. Here’s an exclusive look at what we do to make sure your wall-mounted air conditioner or heat pump performs at its best when the summer heat hits.
A Busy Spring to Guarantee a Comfortable Summer
As temperatures begin to rise, the demand for air conditioning services skyrockets across Montréal, Laval, Longueuil, the North Shore, and the South Shore. That’s why we get to work as early as spring to restart, clean, inspect, or fine-tune the HVAC systems of our clients. This transition period is ideal: it allows us to catch potential issues, prevent surprise breakdowns, and ensure peak performance as soon as the first heatwave arrives.
A Complete Inspection for Every System
Visual and Mechanical Evaluation
From the moment we arrive, our technicians carry out a complete visual inspection of your system: the condition of the outdoor unit, wear on ductwork, proper functioning of electronic components. We also assess the cleanliness of the coils, the condition of the condensate drain, and the integrity of the insulation.
Performance Testing
We then start up the system and perform real-world functionality tests: refrigerant pressure, fan speed, efficiency of the cooling cycle. This allows us to quickly spot any anomalies like a noisy compressor, a possible refrigerant leak, or irregular airflow temperature.
Deep Cleaning: The Core of Our Service
Cleaning the Indoor Unit
One of the most overlooked aspects by homeowners is the buildup of dust and mold inside the indoor wall unit. That’s why we perform a deep cleaning of the filters, fins, fan, and heat exchanger. This step is critical to prevent bad odors, improve indoor air quality, and ensure optimal energy efficiency.
Pressure Washing the Outdoor Unit
Outside, leaves, dirt, and winter debris often clog the unit. We use a specially adapted pressure washer to gently but thoroughly clear the fins without damaging them, ensuring ideal airflow and efficient heat dispersion.
Technical Adjustments: Calibration and Optimization
Refrigerant Check
A system low on refrigerant is not only inefficient—it also consumes more energy. We check and, if needed, rebalance the refrigerant charge, always in accordance with manufacturer standards from brands like Fujitsu, Gree, Bosch, Goodman, Tosot, or Zephyr.
Thermostat Programming
We help our clients properly program their thermostats for the summer season: optimized schedules, comfort-level temperature settings, smart home integration when applicable.
Case Study: Preparing a Wall-Mounted Heat Pump in Laval
Last April, a residential client in Laval contacted us to prepare their Gree Extreme 18,000 BTU wall-mounted heat pump for the summer. The unit was three years old and hadn’t been serviced since installation. When we arrived, we found mold buildup in the indoor unit and a partially clogged condensate drain.
Our technicians performed:
-
A full cleaning of the indoor unit with a biodegradable antibacterial solution.
-
Clearing of the outdoor unit, which was covered in cedar branches.
-
A refrigerant pressure check with a minor adjustment.
-
Reprogramming of the wall thermostat, along with usage recommendations to help lower energy consumption.
Result: one relieved client, and a fully functional, high-performing unit ready to take on the heat.
Why This Preparation Is Essential
Preventing Breakdowns During a Heatwave
An air conditioning failure in July, when it’s 33 °C in Montréal, can be a nightmare. By performing preventative maintenance ahead of time, we reduce the risk of summer breakdowns by over 70%.
Improving Indoor Air Quality
A poorly maintained system can become a breeding ground for bacteria, mold, and dust. Our deep cleaning process contributes to healthier air—especially for allergy or asthma sufferers.
Reducing Energy Consumption
A clogged or poorly calibrated air conditioner can use up to 25% more energy. Our service helps optimize performance while keeping energy bills under control.
What You Can Do While Waiting for Our Visit
As a homeowner, you can:
-
Clean your air filters (at least once a month).
-
Keep the outdoor unit free of debris.
-
Check visually for frost or excessive condensation.
But remember: technical interventions, internal cleanings, and calibration should always be performed by certified professionals like our team at AirGreen.
