Cleaning a Midea wall-mounted air conditioner in Ville Mont-Royal

Professional maintenance to restore life and performance to an HVAC system

At AirGreen , we know how essential regular wall-mounted air conditioner maintenance is to ensure optimal comfort while preventing costly breakdowns. Recently, our team visited Ville Mont-Royal for a complete cleaning of a Midea wall-mounted air conditioner that was showing obvious signs of contamination: bad odor, water leaks from the indoor unit, and loss of efficiency .

Initial diagnosis: a dirty and inefficient Midea appliance

Upon our arrival, we noticed several typical symptoms:

  • Excessive condensation inside the wall unit;

  • Accumulation of dust and mold on the evaporator and tangential fan;

  • Partially blocked drainage , causing slight flow on the wall.

These signs reveal neglected maintenance over several seasons . During the summer, micro-particles accumulated on the fins and the condensate tray not only promote bad odors, but also the proliferation of bacteria that are harmful to indoor air quality.

The importance of deep cleaning

For this type of intervention, we always use a specialized cleaning kit , including:

  • A waterproof cover installed around the unit to channel water and cleaning products;

  • A pressure-controlled sprayer to apply our biodegradable cleaning and disinfecting solution;

  • A temporary drainage system , like the one shown in the photo, allows dirty water to be drained directly into a tank without the risk of splashing.

This method allows you to clean each component without unnecessarily disassembling the device : the evaporator, the fan roller, the fins, the condensate tray and the drainage pipes.

Steps of the intervention

  1. Surface protection : we covered the wall and the surrounding floor to prevent any splashing.

  2. Removing and inspecting the filters : They were heavily clogged with dust. We cleaned them with warm soapy water before rinsing and drying them.

  3. MideaSafe™ Cleaner Application : Our eco-friendly solution dissolved organic deposits and dislodged accumulated dirt.

  4. Pressure flush : Dirty water has flowed through the hose into the tank, taking any traces of mold with it.

  5. Drainage test : After cleaning, we checked the proper flow of the condensate pipe to prevent any future overflow.

  6. Performance Check : The unit was restarted and found to have strong, consistent airflow with no odor or abnormal noise.

Result: restored comfort and better air quality

A few minutes after the service was restarted, the customer immediately noticed the difference:

  • The air blown was fresher and purer ;

  • The ambient temperature stabilized more quickly ;

  • Not a drop of water flowed from the wall;

  • The operating noise was significantly quieter .

AirGreen Recommendations

At AirGreen, we always recommend:

  • A thorough cleaning of the wall-mounted air conditioner in early spring before heavy summer use;

  • Annual preventive maintenance to preserve energy performance and avoid unpleasant odors;

  • The use of certified products that do not harm the evaporator fins or the health of the occupants.

We also remind you that home cleaning of filters never replaces professional internal cleaning , especially when signs such as water, odors or loss of efficiency appear.

AirGreen expertise: precision and respect for your environment

Our certified technicians take care of each installation as if it were their own home. In this project in Ville Mont-Royal , the limited space between the kitchen and the living room required careful installation of the cleaning device , in order to avoid any water splashing on the old woodwork. Thanks to our adapted equipment and our know-how, the operation was carried out without any damage or noise , in less than an hour and a half.

In conclusion

This professional cleaning of the Midea wall-mounted air conditioner in Ville Mont-Royal perfectly illustrates the importance of preventative HVAC maintenance . By restoring the internal cleanliness of the unit, we have:

  • Optimized its energy performance ;

  • Eliminated the risk of water leakage ;

  • Improved indoor air quality ;

  • Extended the life of the system .

At AirGreen , we believe that every service is an opportunity to extend the comfort and peace of mind of our customers in Montreal, Laval, Longueuil, on the North Shore and the South Shore.
