What to expect
How a repair works
You call or send the form.
Tell us the symptom, the system type and your suburb.
We come out and diagnose it.
Call-out usually $100–$150 (check with us for your location). Up to 30 minutes on site, and we tell you what's wrong and what it costs to fix before we touch anything.
We fix it — or we tell you not to.
Most faults are a part, a regas or a clean. If a repair isn't worth it, we say so, and the call-out is included in the price of a new system from us.

Repair reviews

“Dave was a nice guy! He was prompt in replying to us and was flexible to meet us on short notice even though we had a busy schedule. He identified what the problem was and fixed it within an hour! He has great professionalism and was also very helpful and respectful. His prices are reasonable and we highly recommend his services! Thank you Dave! :)”
“Davad is very efficient and very good. He explains the problem and is very prompt in his reply and in his work. Highly recommend him and I, myself, will keep his contact details in my address book so I know who to turn to next time my air con has problems. Thanks, David.”
“Dave was fantastic. Fast communication and friendly. Talked us through the process and what needed doing as it was a little trickier than we first thought. He worked efficiently and finished the job in a few hours. Competitive rates for a good quality service, thanks Dave!”
Questions
FAQ
Do you repair air conditioners or just replace them?
We repair first. If it can be fixed economically, we fix it. If not, we say so — and the call-out fee is included in the price of a new system from us.
How much is a call-out?
Check with us on the call out fee for your location; it is usually $100–$150. It is included in the price if you go ahead with the repair or a new system.
Can you come today?
Yes, we can often come the same day if you call early enough, especially in the shoulder seasons. In a December heatwave it is usually two to four days — call and we will tell you straight.
Which brands do you install?
Daikin, Mitsubishi, Fujitsu, Samsung, Panasonic, Actron and the other major brands. We will also install a unit you have bought, if it is suitable.
