Regardless of the size of your home or business, Coles Refrigeration & Air Conditioning has a range of models that will suit your needs.

split system air conditioner is made up of two parts; an indoor (wall, floor-mounted or ceiling-mounted unit that blows cool air inside and an outdoor unit that releases the heat.


Single split air conditioners are suitable for single room use. It uses a 1 to 1 combination where one outdoor unit (which houses the compressor) is connected to an indoor unit. This indoor unit can be wall-mounted, floor-mounted or ceiling-mounted for easy accessibility.

Cole's tradesmen who carried out the works at our site were always helpful and met our stringent OH&S requirements. The buildings that were refurbished present various challenges with timeframes and meeting relevant codes and standards. With Cole's help, we were able to meet and exceed all expectations. I have no hesitation in recommending Coles Refrigeration for any future works in which they tender.

  • Mitchel Cousins has presented at two workshops held by the Energy Hunter team, helping businesses gain an understanding of real life ways to improve performance, reliability and cost savings of plant and equipment. Mitchell displayed high level of knowledge in both his specific industry, as well as energy efficiency. It was a pleasure working with Mitchell and I would happily do so again.

  • I was on site this morning at 47 Darby Street for the RMS Fitout project, and the foreman was heaping a fair bit of praise on you guys for the quality and speed of work! Thanks for helping us out on this one.
