Doylair was founded in Perth circa 2010 with a simple belief: air conditioning and refrigeration done properly, by people who answer the phone and turn up when they say they will.
We're a family-run, locally owned business based north of the river, led by a certified electrician — which means the electrical side of every installation is handled in-house, safely and to standard, without waiting on a third trade.
From Joondalup to Yanchep, our clients range from homeowners to commercial builders, corporate facilities and industry — and we treat every job like the neighbourhood will hear about it. Because up here, they do.
Tailored heating, cooling and refrigeration for the people and businesses of Perth's north.
Real feedback from real jobs across Perth's northern suburbs.
"Phil was extremely responsive and kept me in the loop through the process of replacing a burnt board and fan motor on a Daikin inverter, giving me multiple options and the time/cost of each. Diagnostic ability was top notch, pricing was fair and work was outstanding. I don't know what he puts in his cornflakes but he's been the best aircon tech I've worked with. 10/10 would absolutely recommend."
"Philip was fantastic to deal with. Communication was easy from start to finish, and despite my tricky air conditioning setup, he took the time to explain everything and was happy to tackle the difficult job. I really appreciate tradespeople who take pride in their work, and Philip's "no job is too hard" attitude stood out. Highly recommend Doylair to anyone with air conditioning issues!"
