A revealing service call in a residential garage
At AirGreen , we were recently called to Sainte-Julie to inspect a Goodman wall-mounted system installed in a garage converted into a workspace. The owner had noticed for several days that the unit was blowing weakly, with an unusual noise coming from the indoor unit.
Our team responded quickly to diagnose and correct the problem, ensuring the heating and air conditioning system returned to optimal performance.
Diagnosis: Obstructed wall unit and sensor misalignment
The unit in question was a Goodman wall-mounted model , typical of compact systems used for isolated rooms such as garages or workshops. Upon our inspection, several anomalies were noted:
-
Clogged filters reducing airflow.
-
Temperature sensor moved , giving false readings.
-
Internal fan slightly unbalanced , causing noticeable vibrations.
These issues, while minor individually, collectively impair system performance. In a garage, dust particles and temperature fluctuations often accelerate the accumulation of dirt on filters and electronic components.
AirGreen intervention: cleaning, realignment and complete calibration
Our technicians undertook a complete maintenance of the system:
-
Thorough cleaning of filters and evaporator to restore optimal airflow.
-
Realigned the temperature sensor and recalibrated internal parameters for a more accurate reading.
-
Checking the electrical connections and the control module , in order to eliminate any potential failures.
-
Tested the fan speed and rebalanced the internal blades to eliminate the noise observed.
In less than two hours, the system was back to smooth and quiet performance.
Result: restored comfort and improved performance
At the end of our intervention, the Goodman unit was able to resume normal operation, providing regular airflow , a stable temperature , and a reduced noise level . The customer immediately noticed a noticeable improvement, particularly in the speed at which the garage warmed up.
We also took advantage of this visit to recommend biannual preventive maintenance , essential for devices installed in dusty environments or subject to strong thermal fluctuations.
