We have used Simac Air-Conditioning on a number of our branch refurbishment projects and I couldn’t recommend them highly enough. In addition to their strong expertise and dedication to the job, they are an absolute pleasure to deal with. Their ability to be flexible and always accommodating makes them a company we will continue to work with in the future.

Paraic Mooney, Mooneys

Simon, Frank and there team carried out our large range of R22 to R410a energy efficient multi VRF & Split type air-conditioning systems in a clean and timely fashion, under the radar of night works & weekends when our tenants were out of the offices. We had zero complaints regarding the installation and would recommend them for such works going forward as we currently do.
