Common questions
My Midea unit heats but will not cool. What is wrong in Dainfern Golf Estate?
That points to the four-way reversing valve sticking or its solenoid coil failing. It can often be freed and the coil replaced without opening the sealed system.
Is a heat pump geyser worth repairing or should I replace it?
If the tank and compressor are sound, repairs are far cheaper than replacement. Where the compressor has failed on a unit older than eight years, we quote both options side by side.
Do you work inside gated estates?
Regularly. Technician details, ID numbers and vehicle registration are submitted to the HOA or gatehouse before the appointment so access is cleared in advance.
