Fully licensed to service and repair systems, and to install them.
We’ve been working on home and commercial systems for more than 20 years. That’s a lot of Perth summers, and a lot of systems we’ve kept going through them.
Many Perth firms hold an installation licence only. Ours covers service and repair work too, so the technician who finds the fault can fix it.
Ducted reverse cycle, cassette, split or VRV, we’ve had over 20 years on all of them, so the advice you get comes from experience.
Every job is quoted upfront, so you know the price before we start. No hidden charges and no surprises.
Been with us before? You get priority when booking a time, as our thanks for coming back.
Here’s what homeowners and businesses around Perth wrote after we’d been out.
"Our Ducted A/C broke down mid December, mid heat wave. Oasis were able to come almost immediately and sent us a quote that afternoon. Parts were ordered and installed just before last weekend’s heat wave. A/C is working great again. Thank you so much and I definitely recommend Oasis Air."
"Aircon broke down mid December, mid heat wave. To my amazement Oasis were able to come within 1 working day to look into and got aircon working within 2 working days, after ordering part required. Im all set for xmas now and a cooler one! Thank you so much and I definitely recommend Oasis Air."
"Highly professional right from my initial contact with the company. My property was left neat and tidy and all components from my previous non working air con unit were removed from my property as part of the service. I would highly recommend Oasis Air Conditioning to others. Thank you."
"Oasis responded swiftly to our enquiry. Our evaporative aircon had stopped working. He located the problem and showed us photos of parts damaged and quoted us on replacements. We decided to go ahead and had the job completed in a few hours. Our system works beautifully again."
"Fast and friendly service. Diagnosed and fixed a problem on the spot that another tech had missed. Thanks!"
"Amazing service, professionals and quick response time. I would highly recommend and have Oasis scheduled for an annual regular service."
We work from Ocean Reef down through Claremont and Cottesloe to Mosman Park, and inland to Ellenbrook and The Vines, plus every suburb in between.
