Essential maintenance to ensure performance and durability
At AirGreen , we always emphasize the importance of regular HVAC system maintenance . A simple preventative cleaning can extend the life of your unit by several years and avoid costly breakdowns. Recently, our team was called to Sainte-Julie , on the South Shore of Montreal , for the complete maintenance of a Midea wall-mounted air conditioner .
A proactive customer and a clogged system
The customer contacted us after noticing a gradual decrease in airflow and a slight damp odor when his air conditioner was running. The unit, installed for four years in a sleek living room, hadn't been cleaned in two seasons.
Our technician opened the top panel of the unit to inspect the air filters , and it didn't take long to identify the cause:
-
Filters saturated with dust and pollen .
-
Partially clogged evaporator coils .
-
Accumulation of residue on the blower turbine.
These factors restricted airflow and forced the compressor to work harder, resulting in excess energy consumption .
Detailed steps of the interview
1. Cleaning the air filters
The Midea washable filters were carefully removed, rinsed with warm water, and then air-dried. This simple action immediately restores some airflow and improves indoor air quality.
2. Degreasing and disinfection of the evaporator
Using a biodegradable, enzymatic-based cleaner, our technician removed the dust film that had accumulated on the evaporator fins. This treatment improves heat exchange and prevents mold growth.
3. Cleaning the blower turbine
Often overlooked, the turbine is one of the most important components to maintain. The blades were partially covered in a sticky deposit. Steam cleaning and a fine brush restored smooth, quiet rotation.
4. Checking the condensate drainage
The drain pipe has been inspected and purged to eliminate any risk of blockage or water backup. A blocked pipe can cause wall leaks and damage the surrounding paint or plaster.
5. Electrical Inspection and Restart
Finally, the technician checked the electrical connections, the control board settings and the response to the remote control. After restarting, the Midea air conditioner was blowing cool air at 9°C at the outlet , confirming optimal performance .
Immediate results
After the interview, the client noted:
-
A significantly stronger airflow ,
-
A more quickly stabilized ambient temperature ,
-
A drop in electricity consumption observed on the smart meter,
-
And above all, the elimination of the smell of humidity .
The whole thing was done in less than an hour, without any complex disassembly, demonstrating that well-planned preventative maintenance is the best way to avoid costly repairs.
Why maintain a Midea wall-mounted air conditioner regularly
Midea air conditioners are designed to be efficient and quiet, but their performance depends directly on the cleanliness of their internal components . Lack of maintenance can cause:
-
compressor overheating,
-
icing of the evaporator,
-
abnormal noises,
-
or premature failure of the blower motor.
That's why, at AirGreen, we recommend a complete maintenance at the start of each summer season . This visit includes:
-
cleaning filters and coils ,
-
checking the refrigerant level ,
-
compressor and drainage test ,
-
and a performance evaluation report submitted to the client.
