A service call in Laval highlighting the importance of quick diagnostics and thorough maintenance
At AirGreen, we were recently called to perform a repair on a wall-mounted heat pump by the brand Okyotech, in a home located in Laval. This unit, installed in a central living area, was showing signs of malfunction that affected both cooling and heating functions. This kind of service call showcases not only our technical expertise but also our ability to resolve issues in a targeted, quick, and long-lasting way, all while ensuring the customer’s comfort.
Problem reported by the client: unit was running, but ineffective
The client contacted us after noticing that the Okyotech wall-mounted heat pump appeared to be running — indicator lights were on, the louvers opened — but no adequate temperature was being achieved, in either heating or cooling mode. Another troubling sign: a slight irregular vibration noise, mostly noticeable at night.
Given the situation, our team immediately scheduled an on-site HVAC repair visit.
Initial inspection and diagnostics: identifying an internal airflow issue
During our visit, we conducted a full inspection of the indoor unit, starting with checking the filters, the blower wheel, and the heat exchanger. We then analyzed the internal error codes of the Okyotech unit using our compatible diagnostic reader.
Several key findings:
-
The air filters were moderately clogged (fine dust buildup),
-
The blower wheel had a misalignment issue, causing intermittent noise,
-
The indoor temperature sensor was sending inconsistent data to the control board,
-
Refrigerant levels were within normal range, yet the thermal output was insufficient.
Specific repair steps performed by AirGreen
To restore the unit to optimal performance, here are the technical actions taken by our certified technicians:
-
Thorough cleaning of the indoor unit:
-
Removal of filters and top cover,
-
High-pressure cleaning of the filters and rinsing with antibacterial solution,
-
Manual dusting and wiping of the blower wheel and coils.
-
-
Realignment of the blower wheel:
-
Power disconnection,
-
Partial disassembly of the motor compartment,
-
Adjustment of the rotation axis and lubrication of the bearings.
-
-
Replacement of the indoor temperature sensor:
-
Installation of an Okyotech-certified replacement sensor,
-
Connector installation and test of ambient temperature response.
-
-
Final system checks:
-
Cold and hot start-up testing,
-
Airflow measurement and temperature differential analysis at the vents,
-
Monitoring for any unusual noise and confirming vibration elimination.
-
Result: optimized performance and restored indoor comfort
Following our intervention, the Okyotech wall-mounted heat pump resumed full efficiency in both heating and cooling modes. The client immediately noticed a better temperature distribution, a quieter operation, and improved responsiveness when switching modes.
We also took the time to advise the homeowner on the importance of regular preventive maintenance, especially before winter and summer, to ensure long-term performance from their system.
Specific installation notes from Laval
It’s worth noting that this Okyotech unit was installed in a central hallway, near a split-panel decorative painting. During our intervention, we made sure to protect the artwork with anti-static covers, demonstrating our attention to detail even in non-technical aspects.
The wall configuration and sufficient clearance allowed us to dismantle the unit without complex maneuvering, which helped reduce the repair time.
