A sudden breakdown in the summer heat
In the middle of a summer afternoon in Pointe-Claire , on Montreal's West Shore , we received a call from a panicked customer: their Elite wall-mounted air conditioner refused to start. With temperatures reaching 30°C, indoor comfort had become unbearable. Our AirGreen team quickly arrived on site to perform a complete diagnosis of the HVAC system .
Fast and accurate diagnosis: AirGreen professionalism
Upon arrival, our technicians found an Elite wall unit installed in a central hallway, just above a door—a common but often poorly ventilated location. The customer explained that the unit was no longer responding to the remote control and that no indicator lights were illuminated.
Our diagnostic steps:
-
Power supply check : No current detected at the unit's input terminal.
-
Electronic control panel test : no voltage - suspected faulty main board .
-
Circuit breaker and wiring inspection : no visible anomalies.
-
Direct test on emergency power : the interior fan briefly started, confirming that the motor was not the cause.
The verdict: Main circuit board fried , probably as a result of an electrical surge during a recent storm.
On-site repair: immediate restart
At AirGreen, we have a mobile inventory of parts compatible with Elite systems , so our technician was able to replace the control board on-site, saving the customer a second visit.
The steps:
-
Complete disassembly of the front panel and electronic box.
-
Installing a new Elite compatible motherboard .
-
Cleaning the filters and internal temperature sensor.
-
Complete testing of airflow and cooling cycles.
In less than an hour, the unit resumed normal operation: cold air, silent and perfectly distributed in the room.
Result: restored comfort and prevention of future breakdowns
Before leaving, we advised the client to:
-
Install an HVAC surge protector to protect the circuit board from frequent electrical fluctuations in the area.
-
Clean filters every four weeks , especially during periods of heavy use.
-
Have the refrigerant gas checked every spring to avoid performance drops.
This intervention made it possible to restore interior comfort immediately , while extending the life of the Elite air conditioner .
