Mitsubishi Heat Pump Regassing in Johannesburg

Mitsubishi heat pump regassing across Gauteng. Inverter plant with detailed diagnostics and strong parts support.

Mitsubishi equipment we work on includes ecodan and commercial heat pump ranges. Commonly replaced parts on this brand are inverter boards, sensors, pumps, and we keep or source these against the unit's model and serial plate rather than by guesswork.

A heat pump is a sealed system: if it is short of gas, there is a leak. Simply topping up sends the same refrigerant back into the atmosphere within months and masks the fault. We pressure-test, trace the leak, repair it, evacuate to vacuum and then charge by weight to the manufacturer's plate data.

Control scheduling is often the cheapest available improvement, particularly where heating windows overlap with peak tariff periods. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
