Based in Melbourne's eastern suburbs, we service Doncaster and all surrounding areas including Templestowe, Donvale, Doncaster East, Warrandyte, Bulleen and Box Hill — from homes on the high side of Doncaster Road to quieter streets near Ruffey Lake Park. Doncaster has a real mix of housing: original 70s and 80s brick family homes sitting alongside newer townhouses and larger rebuilds up around the Westfield and Doncaster Hill precinct. We fit split systems into the townhouses where roof access is tight, and full ducted refrigerated systems into larger double-storey homes where a single unit needs to cover multiple living zones. For heating, gas ducted is still the most common choice across the established homes in the suburb.

Would highly recommend OnePeak!! Our evap run its course and needed to be changed. We had a few people have a look at it and decided to go with Lachy! His personality and transparency put us at ease.

Lachie patiently discussed the cooling options available to us and we decided on 3 individual split systems. His team arrived at the agreed time and worked in an efficient, professional manner. They cleaned up carefully after the job. We are very happy with the work and the cost of the job, and highly recommend them.

Highly recommended. Lachy fixed the gas heater at a highly competetive price. He did a fantastic job, so we got him to service the evaporative cooling. Again, Lachy was fantatsic, did a great and thorough job. We are recommending him to everyone.

Had a really good experience with OnePeak supplying and installing our new split system. The guys were easy to deal with, turned up when they said they would, and clearly knew what they were doing. Everything was smooth from start to finish and the system works great. Would definitely recommend them.
