Severely dirty condenser coil caused poor cooling.

A real BLU service call showing why professional condenser cleaning reaches farther than a quick rinse through the cabinet.

Outdoor AC condenser coil severely impacted with grass clippings and dirt in Albany, Louisiana

THE DIAGNOSIS

Airflow was almost completely blocked.

The homeowner reported that the air conditioner was not cooling properly and could not keep up during the hottest part of the afternoon. After removing the condenser’s exterior panels, BLU found the outdoor coil severely impacted with grass clippings, dirt and outdoor debris.

THE WORK

Full access. Thorough cleaning. Verified operation.

BLU removed the cabinet panels to reach the complete coil, applied a non-microbial coil cleaner and thoroughly rinsed away embedded debris with pressurized water. After reassembly, the system was restarted and proper cooling was verified.

Why this matters

Restricted airflow reduces heat rejection and cooling capacity. It can also increase operating pressures, electrical demand, run time and strain on the compressor and condenser fan motor.
