Supply and neat installation of energy-efficient inverter midwall split air conditioners (9,000, 12,000, 18,000, 24,000 & 36,000 BTU), including core drilling, copper piping, trunking, and bracket mounting.
Full indoor evaporator and outdoor condenser coil wash, anti-bacterial & mould treatment, filter sanitizing, condensate drain line flushing (stops indoor water leaks), and amp-draw inspection.
If your aircon blows warm air or ices up on the copper pipes, we perform nitrogen pressure testing, flare-nut or brazed joint leak repairs, vacuum dehydration, and accurate R410A or R32 refrigerant recharging.
Troubleshooting error codes, failed start/run capacitors, indoor/outdoor fan motors, PC board surge damage, contactor replacements, and units that trip the main earth leakage or circuit breaker.
Aircons wired illegally into plug circuits fail Electrical CoC inspections. We install dedicated DB circuit breakers, correctly sized cabling, and weatherproof lockable outdoor isolator switches.
