As part of our regular service calls across the South Shore, our team recently responded to a HVAC service call in Delson regarding a PerfectAir wall-mounted heat pump installed in a residential living room. The client reached out to us due to a lack of heating performance, despite having a relatively new unit. This type of service perfectly reflects our commitment to delivering professional, fast, and transparent HVAC service, with meticulous attention to every technical detail.
Background of the Call: Inadequate Temperature and Weak Airflow
The client, living in a single-family home in Delson, noticed that the PerfectAir wall-mounted heat pump – installed less than three years ago – was no longer providing enough warmth to maintain a comfortable temperature in the living room, even when the thermostat was set above 23°C. Additionally, the airflow seemed weak, even with the fan speed set to maximum.
Full System Inspection
Upon arrival, we performed a complete system diagnostic:
-
Checked the operating mode (heating vs cooling)
-
Inspected the fan speed settings
-
Assessed the outdoor compressor unit (no error codes displayed)
-
Inspected the indoor evaporator and fan
-
Checked the air filter and heat exchanger for cleanliness
Our tests revealed that the swing flap was partially stuck, which limited the direction and reach of the warm airflow. On top of that, the air filter was slightly clogged, reducing the unit’s ability to properly capture and distribute conditioned air.
Immediate Corrective Maintenance
We carried out a full filter cleaning, removed the swing flap to unblock and realign the motor arms, and ran a reset of the indoor PerfectAir unit. At the same time, we cleaned the temperature sensors, which are often responsible for inaccurate readings in dusty or poorly ventilated areas.
Result: Restored Performance and a Reassured Client
Following our service:
-
The airflow was fully restored
-
The temperature rose from 18°C to 23°C in under 20 minutes
-
The swing flap resumed full functionality in all directional settings
-
The client could immediately feel the difference in comfort
We also took the time to educate the client on the importance of regular maintenance, including cleaning the filter every 2 to 3 months, especially during periods of heavy heating usage.
Technical Analysis: The Importance of Flap Mechanics and Filter Cleanliness
This type of malfunction is common among mid-range wall-mounted models, especially when the unit isn’t properly maintained. The flap motor is a moving part that can easily become misaligned or jammed, particularly in dry or dusty environments.
At AirGreen, we emphasize a preventive approach: avoiding major breakdowns through seasonal inspections. In this particular case, a simple check-up would have detected the beginning of the swing flap issue before it significantly impacted airflow.
