I think it’s the first time in my 30 years on this planet where I’ve witnessed a tradie arrive on site at the specified time. Nathan and Daniel were timely, thorough and incredibly lovely, especially considering today is expected to reach around 42 degrees. Also very happy with the communications received from WestOz – very punctual and efficient. I will be recommending WestOz to friends and family requiring skilled trades services. 2 thumbs up, and very happy our air conditioning is working again!

Just had WestOz install a new split system on the 41 degree day (1 Feb) and boy was it handy. Works like an absolute treat and the service of the install crew did was awesome. Jake was on the ball with him and his offsider doing a beautiful job. Very very professional and not putting a foot wrong. Would recommend them in a flash.

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.

Thank you Nathan & Daniel from WestOz for your outstanding service today! Not only were you earlier than scheduled but also friendly and efficient. I’ll be sure to reach out should your services be required again and recommend you in the future. Thanks again!

Perfectly integrated air conditioning from day one

Installing your aircon during construction allows for optimal design, seamless integration, and ultimately, more money in your pocket — but only if you get it done right the first time. It’s the difference between a system that huffs and puffs through the summer and one that breezes through a 40-degree day. The difference between costly adjustments down the road and a perfectly tailored, energy-efficient system that’s built to last. At WestOz, whether it’s a residential or commercial development, our new construction air conditioning installation process respects your project’s budget, timeline, and design, ensuring your system is ready to perform from day one.

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.
