ompany Directors, Stephen O’Brien and Dean McDonald formed the company in 1998 after many years experience in the heating, cooling and plumbing industry. Dean and Stephen started McDonald O’Brien specializing in evaporative cooling and gas ducted heating, It wasn’t long before the first showroom was built in Norton St. Wangaratta making room for wood heaters and gas space heating.

Due to much required expansion, Dean and Stephen purchased 17 – 19 Muntz Street which stood as a previous plumbing store (Dent and Wood), a new state of the art showroom was built housing evaporative coolers, gas heating, hot water systems, wood fires and the largest working range of gas log fires in Wangaratta. Dean and Stephen also introduced misting into Australia, via their other company OzMist which operates and manufactures from the Muntz Street premiss.

In 2005 McDonald O’Brien became the dealers for Solahart, providing solar hot water solutions for both residential and commercial properties.
Now in our 17th year of operation McDonald O’Brien have recently refurbished our showroom, to keep up to date with market trends, and recently becoming the Daikin Specialist dealer for Wangaratta.
