Techsun Heat Pump Regassing in Greenstone
Techsun heat pump regassing in Greenstone. Common on guest house and complex installations; scale management extends compressor life.
Techsun equipment we work on includes commercial hot water heat pumps. Commonly replaced parts on this brand are heat exchangers, controllers, 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.
Retail, medical and residential development with centralised hot water systems. Medical facility hot water compliance checks available. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
