Fast and precise intervention to bring an essential HVAC system back to life
At AirGreen , we know how essential a high-performance wall-mounted air conditioner is during the hot weather in Greater Montreal. Recently, our team was called to La Prairie , on the South Shore , to diagnose and repair a Midea wall-mounted air conditioner that was showing signs of reduced performance and abnormal noise .
This type of intervention is part of our daily expertise: quickly restoring comfort to homes while optimizing the durability of their equipment.
Diagnosis: When comfort diminishes, the signs speak for themselves
The customer contacted us after noticing that their outdoor unit seemed noisier than usual and that the air blown inside was no longer as cool . Upon arrival, we conducted a complete inspection:
-
Visual observation of the outdoor condenser: accumulation of dust, pollen and debris on the fins.
-
Checking the pressures of the R-32 refrigeration circuit.
-
Listen for fan noise : irregular vibration indicating imbalance or slight obstruction.
-
Electrical connection inspection : test of the starting capacitor and compressor.
The result: energy efficiency was reduced by almost 25%, a typical situation when heat exchange is disrupted by dirt or blocked airflow.
Intervention: technical cleaning and performance readjustment
To restore the optimal functioning of this Midea wall-mounted air conditioner , our certified technician undertook a series of precise actions:
-
Deep cleaning of the external condenser , with gentle and safe rinsing for the fins.
-
Fan check : remove debris stuck in the casing and balance the blade.
-
Checked the R-32 refrigerant level to confirm that no leaks were present.
-
Testing the compressor and start relay , ensuring that start-up was done without overload.
-
Cleaning the internal filter and resetting the eco mode.
After cleaning and adjustments, the outside noise level dropped by 12 dB , and the inside blowing temperature returned to an impressive 8°C in cooling mode .

Recommended best practices for South Shore residents
For our customers in La Prairie, Brossard, Candiac or Saint-Bruno , we remind you of some simple advice:
-
Clean your internal filters every four weeks during the warm season.
-
Visually check the outdoor unit in spring to clear any leaves, dandelion flowers, or cobwebs.
-
Avoid airtight covers or shelters on the condenser: they block ventilation and reduce the life of the compressor.
-
Have your HVAC system inspected once a year by an AirGreen technician to maintain the manufacturer's warranty.
Regular maintenance can save up to 15% of energy , while extending the life of the system by several years.
