Air conditioning and Heating

Running your AC during winter will help maintain the system in good working order. Air conditioning systems contain a myriad of hoses and seals that can dry out or crack, which could lead to Gas leaks and poor performance.  

Car air conditioning doesn't only keep you cool on hot days, but can also remove humidity, which can be handy in the winter to help counteract a foggy windscreen.

During A regular Air conditioning service we will check for obvious faults which may be associated with the air conditioning system, such as drive belt tension, visible signs of refrigerant leaks and loose or faulty compressor or equipment mounting brackets, but it is good practice to have a comprehensive air con service every 2 to 3 years to keep your air-conditioning working perfectly and keep everything in order to prevent costly repairs.

Our Specialist Trained and licensed technician will perform a series of checks, balances, repairs and replacements to get your air conditioner in top condition

No Heater Working? We can repair all heating faults from blocked or leaking heater cores to faulty heater taps and controls.

If your car air conditioning system  isn’t running efficiently, needs a regas, or you haven’t had it serviced for a long time, Go ahead, call us today and book in your car air conditioning service from just $99* plus parts and gas.
