Air Conditioning

When you call a Cervas technician you will have the peace of mind that comes from our ability to service and repair both air and water-cooled units. We offer a “One Call Service Solution” approach to servicing your equipment - providing maximum efficiency and quality.

By having an integrated service you will not be told you need to call a different technician due to it being another type of issue than was at first thought, saving you both time and money.

Our highly experienced technicians can repair, service or overhaul your commercial air conditioning units, saving on energy costs and preventing failure under extreme circumstances such as heatwaves or under extensive usage during peak times.
