  • Aaron recently installed a new ducted air conditioning system for us, and we couldn’t be happier with the experience.

  • Aaron and the boys did a bang up job. Even when things weren't going their way it got sorted.

    Fletcher Moore Google review · May 2026

  • Neat and tidy, quality workmanship all around. I'd recommend them if you're looking for a first rate solar/battery installation.

  • He installed nine new light fixtures for us and was meticulous in the positioning and installation. They look great and we are beyond happy with the service provided.

  • It is rare these days to find a company that genuinely cares about its customers beyond the point of sale. Arlite absolutely does.

About air conditioning fault finding

Air conditioning fault finding in Brisbane

When an air conditioner is not cooling, not heating, making a noise or leaking, the first job is finding out why. Guessing at the cause leads to repeat visits and repairs that do not hold.

We test the system methodically to find the actual fault, explain what we have found in plain language, and recommend the right repair before any work begins.

The work is carried out by our own licensed team, and we test the system again before we leave. We service ducted, split and bulkhead systems across Brisbane.

  • Common causes include dirty filters or coils, electrical faults, blocked drainage and worn components. The right answer comes from testing the system, not guessing.

  • Possible causes include dirty filters, blocked airflow, a tripped breaker, a control or sensor fault or a refrigerant issue. Checking the filters and the breaker is a safe first step, and if the problem remains we test the system to find the actual cause.

  • A leak is often caused by a blocked or poorly draining condensate line, though other faults can be responsible. Turn the system off if water is dripping near electrics and book a fault-finding visit.

  • Yes. We tell you what we have found, what we recommend and why before any repair is carried out.

  • Yes. Our team can diagnose and repair existing ducted, split and bulkhead systems.

  • Sometimes. If poor airflow or odour is the issue, a deep clean may help, and we will tell you if that is the case.

  • Installation of an EV Wall Charger, and the boys did an amazing job. Left the site clean.

    Casey Walsh Google review · Aug 2026

  • Aaron went out of his way to research a range of options for us, some we had not considered, which turned out fantastic.

    Shane Fracchia Google review · May 2026

  • They are a family run business so you deal directly with them rather than an outsourced contractor for the solar and battery installation.

    Nick Robs Google review · May 2026

  • In less than two days they completed all the work and took away all old panels and I could see the performance of the system right on my phone.
