How we get your
AC working again.
We start with a proper diagnosis rather than guesswork — checking the indoor and outdoor unit, electrical supply, drainage, airflow, filters and refrigerant performance to find the real cause of the fault.
Once we know what's wrong, we explain it in plain language along with the repair options, so you can decide whether to repair the system or look at replacement.
Most residential faults are repaired on the spot. Where a part needs ordering, we let you know the timing up front and get you back to comfortable as quickly as possible.

FAQs
Common questions.
My air conditioner is blowing warm air — is that a big repair?
Not always. It can be as simple as a blocked filter or dirty outdoor coil, or it may point to a refrigerant or component fault. We diagnose it first, then explain the options before any work goes ahead.
Do you repair all residential brands?
We work on common residential split system and ducted air conditioning systems. Tell us the brand and model when you call and we'll confirm.
Should I repair or replace my old system?
It depends on the age of the system, the cost of the repair and how well it has been running. We give you an honest comparison so you're not spending money on a system near the end of its life.
Where do you carry out repairs?
Across Sydney, from our base in Earlwood NSW.
