A service call to restore comfort to an elegant Outremont apartment
At AirGreen , we were recently called in for an HVAC service call to a charming apartment in Outremont , a neighborhood where aesthetics and interior comfort are always priorities. The customer contacted us after noticing that their Sharp wall-mounted air conditioner was no longer producing cold air, despite the unit seemingly operating normally.
Accurate Diagnosis of Sharp Wall Air Conditioner
Upon arrival, our certified technician conducted a thorough system inspection. The Sharp indoor unit, installed on a wall adjacent to a west-facing window, was displaying an intermittent error code related to the room temperature sensor . This symptom was manifested by warm air blowing and frequent compressor restarts .
Our technical checks have revealed:
-
A buildup of dust on the evaporator fins , reducing airflow.
-
A faulty thermistor probe , responsible for an incorrect temperature reading.
-
No refrigerant leaks or obstructions in the refrigeration line.
Repair Steps
Our team carried out a complete disinfection of the indoor unit , including:
-
Cleaning the filter and blower turbine.
-
Clean the fins using a non-corrosive product.
-
Replacement for the original Sharp temperature sensor .
Then, a full operational test confirmed the return of a normal cooling cycle and a stable blowing temperature at 8°C . The customer immediately noticed the difference, both in performance and operating silence.
Maintenance and prevention tips
We recommended to the client:
-
Clean the air filter every three weeks during the summer season.
-
Schedule annual maintenance before each summer to extend the life of the device.
-
Avoid blocking airflow with curtains or furniture placed too close to the unit.
