Why Choose Split Systems for Commercial Use?

Split systems are one of the most popular choices for smaller commercial spaces because they provide comfort without the complexity or expense of larger systems. They are well-suited to individual offices, staff rooms, retail areas and reception spaces where targeted climate control is needed. The installation process is straightforward in both new and existing buildings, making them a practical solution when you need reliable heating and cooling with minimal disruption.

Businesses also value split systems for their efficiency and quiet performance. Modern inverter technology adapts to the demand of the room, reducing running costs while maintaining steady comfort. With noise levels as low as a whisper, these systems create a pleasant environment for staff and customers alike. They are also easy to operate and maintain, ensuring ongoing reliability and peace of mind.

Client Reviews

  • I just thought I would share some feedback with you on this very hot day. In the past, our air conditioning has always struggled badly on these hot days.The guys out the front (with glass windows) would be sweating and they would turn the air right down. The people in the back of the office would need to bring jumpers and cardigans to work on a day like this. BUT NOW – AFTER YOUR TECHNICIAN WAS HERE LAST MONTH. It’s fantastic.  We have been in this building for 10 years and the air conditioning has never worked better!! So thank you to everyone there for making that happen for us. We are all very happy and have been mostly unaware that it’s even a hot day out there. We love it!!

  • Thank you Coles Refrigeration & Air Conditioning for the professional work you produced in installing the bar and kitchen at the Mark Hotel.

    Your professionalism, quality, honesty, and delivery timeframes were outstanding given you were under an extremely tight schedule to get the project completed. I was especially impressed with your effort to accommodate any additions to the original scope, including the client's request to refurbish the entire kitchen two weeks prior to Christmas. I have no hesitation in recommending you and Coles Refrigeration & Air Conditioning to future clients and trust we will continue to further strengthen the relationship between our companies.

I have conducted business with Coles since 1994. I have no hesitation in recommending Coles Refrigeration & Air Conditioning to prospective clients.

  • Thank you for the excellent work produced by your staff during the fit out of our new kitchen. The stainless steel exhaust and benchwork are second to none. Our cool room, pantry and freezer are working beautifully and the shelving and the layouts are exactly to our requirements. I will always be available to be contacted to recommend the work you and your staff did on our new kitchen.

  • 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.
