How to Choose an Aircon Installer in Perth

19 August 2026 · 6 min read · Fix My Aircon

Why the installer matters more than the brand

Most people shop for a brand first and worry about who fits it second. That is backwards. A quality unit installed badly will short cycle, ice up, drip, run noisy and cost more to run than a mid-range unit installed properly. Roughly speaking, poor installation is behind a large share of the early faults we get called out to across Perth.

The good news is that a decent installer is easy to spot once you know what to look for.

Check the licences before anything else

In Western Australia, air conditioning work touches three separate regulated areas. Ask for numbers, not reassurance.

  • Refrigerant handling licence (ARC) — required for anyone opening the refrigeration circuit, including charging and re-gassing. You can search an ARC licence number online.
  • Electrical licence (EW/EC) — required for the hard wiring and isolator work on a new install. Check it on the WA Building and Energy register.
  • Business registration and public liability insurance — ask for the certificate of currency, not just a yes.

Anyone who hesitates when asked for these is telling you something useful.

Questions worth asking before you accept a quote

  1. What size did you calculate, and how? A proper installer measures the room, checks orientation, ceiling insulation, glazing and how many people use the space. If nobody has looked at your home or floor plan, the sizing is a guess. Our aircon size calculator gives you a sanity check number to compare against.
  2. Where exactly will the outdoor unit go? Western sun on a condenser in a Perth February makes the whole system work harder. Shade, airflow clearance and distance from bedroom windows all matter.
  3. How long is the pipe run, and is it included? Long runs on a two storey home or a Perth Hills split level are where surprise costs appear.
  4. Who honours the warranty? Manufacturer warranty usually needs proof of licensed installation and, on many brands, evidence of servicing. Ask who comes back if it fails in year three.
  5. Do you handle the old unit and the make good? Removal, disposal and patching brickwork should be written down.

Quote red flags

  • A price given over the phone with no site visit and no photos.
  • A quote that is one line and one number. A fair quote itemises the unit, the install labour, pipe run, electrical work, brackets or roof penetrations, and commissioning.
  • Cash only, large deposit up front. A deposit is normal. Most of the money before any work starts is not.
  • Pressure to decide today because of a discount that expires today.
  • No written commissioning data. A good installer records the running pressures and temperatures on handover.

What a fair Perth install actually includes

Expect the quote to cover the unit, wall brackets or a ground stand, insulated and lagged pipework, a condensate drain that runs somewhere sensible, an isolator switch, testing under load, and a walkthrough of the controller. If you are looking at a whole home system, see our guide on ducted air conditioning installation for how the ducting and zoning side is priced.

After the install

The install is the start, not the end. Filters need cleaning through summer, and a split system service or ducted service once a year keeps warranty conditions intact and running costs down. A maintenance plan makes that automatic, and a health check is a low cost way to find out whether a system you inherited with the house was installed properly in the first place.

If the unit you already have is playing up, our aircon repair team can tell you honestly whether it is worth fixing or worth replacing.
