The guys from WestOz Trades installed 4 outlets plus the unit today 4/9/24. They did an extremely professional job in terms of communication and workmanship. We couldn’t recommend them highly enough.
Ali S.
My experience with WestOz Trades has been really good. From the day Chris rocked up on my door, to the quote all the way through to installation of my air controller (plus increasing the zones from 4 to 8). The process was smooth. The people I dealt with were professional and punctual. The service they provided and the end result, I couldn’t have asked for more. Would definitely recommend these guys.
Shane R.
We just had a new aircon unit installed at our apartment today by the men from WestOz trades, George, Stewart and Connor were very professional friendly and competent in all the components of their work. I would have no problem giving them a great reference to their work. Many thanks men cheers Shane.
Grant N.
Just had a new Mitsubishi Heavy Industries 12.5kw reverse cycle air conditioner installed, replacing an old unit. Couldn’t be happier with the service provided by WestOz Trades. From initial contact with Chris in the office to the tradesmen who fronted up on the day, the job was carried out efficiently and professionally.
Zackarias L.
I would like to express my high praise for WestOZ Trades’ exceptional service and professionalism. From start to finish, their team demonstrated a commitment to excellence that was truly impressive. They arrived on time, promptly addressed all my inquiries, and installed a ducted reverse cycle air conditioning system that has performed flawlessly for nearly three months.

Air conditioning installation in Perth — done right the first time

We don’t need to tell you that climate control makes life more comfortable. What matters is meticulous air conditioning installation in Perth, tailored specifically to your property. It’s the difference between a system that huffs and puffs through the summer, inflating your electricity bill, and one that hardly breaks a sweat on a 40-degree day. The difference between costly replacements and a little maintenance here and there. The difference between a company that crams an aircon into your ceiling and never speaks to you again… and WestOz, an expert team that respects you and your property and ensures your air remains fresh for years to come.

Why choose us as your air conditioning installers in Perth?

Professional but personable

We’re professionals, but we’re also friendly. We respect your property, make sure your pets don’t get out, clean up after ourselves and we pride ourselves on all being good humans.

Clear, honest communication

We respond quickly, honestly, and in plain English, avoiding industry jargon. With us, if you don’t need something, we’ll tell you, not sell you.

On time, every time

We understand the frustration of waiting for someone who doesn’t value your time. That’s why we’re committed to punctuality, ensuring we arrive exactly when scheduled — every time.

No hidden fees

We believe in transparent, upfront pricing. No shortcuts, no surprises — just clear, honest communication from day one.

Only the best technology

We only install the very best air conditioning products. For reliability, you can’t look past high-end brands like Mitsubishi, Samsung, and Hisense.

Refrigeration mechanics, not electricians

We’re fully qualified air conditioning and refrigeration mechanics — not electricians or generalist tradies. Air conditioning is our specialty, our expertise, and our passion.

48-hour response time for issues

If you’re an AirCare member and have any issues with your air conditioning, we’ll be there within 48 hours to help, even in the peak of summer.
