A commercial warehouse facility in Blackburn
A multi-split system in a busy commercial office starts blowing warm air during a seasonal temperature spike, risking staff discomfort and system shutdown.
- 1Rapid Fault IdentificationOur engineer isolates the system and pinpoints a blocked outdoor coil restricting heat exchange.
- 2Preventative Coil WashChemical cleaning removes years of accumulated dust and grime, restoring normal airflow.
- 3Refrigerant Level CorrectionWe test system operating pressures to ensure no refrigerant was lost during the overheat.
- 4Restored Energy EfficiencyThe system draws less current, lowering operational costs and stabilizing indoor temperatures.
Restoring Airflow to a Blocked Condenser System
The technician performs a thorough chemical deep clean of the external condenser units and replaces the clogged internal air filters. After verifying that the electrical connections and fan motors are operating within manufacturer specifications, we run the system through a full cooling cycle to confirm the temperature drop across the coils is correct.
- Deep chemical wash of external condenser fins
- Internal return air filter replacement
- Operating pressure and current draw testing
- F-Gas logbook updated with system parameters
