I recently purchased a Mitsubishi split system air conditioner for our bedroom from Hinterland Air in Lennox Head. It was a 2.3kw system, and the price was $1,350 fully installed, which i thought was reasonable. The staff were friendly, installation was quick, and unlike a lot of other tradespeople we've had in our house, they didn't leave a mess. The unit is excellent and we are very happy with a job well done!
