Most modern offices and commercial buildings feature air conditioning to help improve the comfort levels for employees and visitors, as well as boost motivation amongst staff. From offices and retail spaces to warehouses and computer server rooms, there are a range of air conditioning models available to suit the size, purpose and requirements of different applications.

Coles offer a range of affordable comfort options suitable for single room use. Designed for Australian conditions, these products are ideal solutions to efficiently heat or cool single room spaces, and are also easy to install, service, and maintain.


Systems for use in commercial applications with 1 to 1 combinations (1 indoor and 1 outdoor unit), with various types of indoor unit: Cassette and Wall Mounted.


Wall mounted air conditioning systems are the entry level air conditioning system comprising of a high level indoor unit connected to a single outdoor unit. These wall mounts are ideal for small to medium sized applications and also offer energy savings over conventional forms of heating.

  • Cost effective installation in new or old buildings
  • Quiet operation – down to 24 dBA at the lowest setting, ideal for offices
  • Vertical auto swing function allowing an even distribution of air
  • Energy efficient – up to Class A rating (ECA qualifying)
  • Simple infrared remote controls


A cassette air conditioner works in a similar way to a standard air conditioning system by drawing in warm air from the interior of the room and cooling this air using a cooling element which contains refrigerant. This model features an internal unit which is installed into the ceiling, making it ideally suited to buildings with suspended ceilings as it takes up little room. It also has an outdoor condenser where the cooling process is carried out which, as the name suggests, is fitted on the exterior of a building.

What stands cassette air conditioners apart from traditional air conditioning systems is how they are mounted which, in itself, can boast a plethora of benefits.

  • Extremely quiet during operation
  • Good coverage and wide distribution of cool air
  • Unobtrusive
  • High cooling output
  • Easily accessible for maintenance
  • Versatile design: available in a range of sizes and capacities
  • Energy efficient: adjustable thermostats and variable speed fans

  • Throughout all the stages of development and construction, I always found the staff from Coles to be highly professional and diligent in their works. 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.
