Heat Pump Maintenance in Johannesburg & Gauteng

Scheduled servicing that keeps COP high and prevents compressor failure.

Maintenance on a heat pump is mostly about airflow, water flow and electrical integrity. A fouled evaporator or a scaled condenser drops the coefficient of performance long before the unit fails outright, and the extra running hours are what eventually kill the compressor.
