Heat Pump Regassing in Cedar Lakes
Heat Pump Regassing in Cedar Lakes covers leak detection first, then correct-charge regassing by weight. Cedar Lakes is a high-value residential pocket of Fourways, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom.
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.
The installed base here is mostly domestic and estate housing, so work concentrates on single units, multi-geyser homes and shared complex plant. Cedar Lakes falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs.
Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet. Peak draw-off matters more than total daily volume: plant that satisfies a whole day of demand can still fail at a 45-minute shower peak.
