We've been designing and constructing commercial air conditioning systems since 1977, when RJ Air founder Ron Long and his company worked on the mechanical upgrades for the Ramsay Health Group.

Since then we've designed air conditioning systems for dozens of commercial businesses, including Anytime Fitness, Roses Only and the Bourke Street Bakery stores.

More recently, we've created systems for Coogee Pavilion, Snap Fitness and The Paddington for Merivale Group.

Using world-class technology for a long-term mechanical solution, our custom air conditioning systems deliver significant energy savings, real environmental benefits and greater financial returns.
