Frequently Asked Questions – Car Air Conditioning
Do you provide mobile car air conditioning services across Perth?
Yes. CMM Automotive provides mobile car air conditioning services throughout Perth, allowing us to inspect, diagnose and repair many air conditioning problems at your home or workplace.
How do I know if my car air conditioning needs a regas?
If your air conditioning is blowing warm air, taking longer than normal to cool the vehicle or simply isn’t as cold as it used to be, the system may be low on refrigerant. However, low refrigerant can also indicate a leak. We recommend checking the system before carrying out a regas.
Can you diagnose why my car air conditioning isn’t cold?
Yes. We use professional diagnostic equipment to check the operation and performance of your vehicle’s air conditioning system. This can help identify problems such as low refrigerant, leaks, compressor faults or other system issues.
Do you check for leaks before regassing the air conditioning?
Yes. We believe it is important to understand why an air conditioning system has lost refrigerant before simply recharging it. If we identify a leak or another fault, we’ll explain what we’ve found and discuss the most appropriate repair.
How often should a car air conditioning system be regassed?
There isn’t a set regas interval that applies to every vehicle. A correctly operating system should not require frequent regassing. If your air conditioning is losing cooling performance, we recommend having the system inspected to determine the cause.
Can you repair car air conditioning systems as well as regas them?
Yes. CMM Automotive provides car air conditioning diagnosis, servicing and repairs. Depending on the fault, repairs may involve components such as compressors, condensers, receiver driers, expansion valves, hoses and other parts of the air conditioning system.
What vehicles do you provide air conditioning services for?
We provide mobile air conditioning services for a wide range of passenger cars, 4WDs, SUVs, utes, vans and light commercial vehicles throughout Perth.
Can you come to my home or workplace?
Yes. CMM Automotive is a mobile automotive service, so we can come to your home or workplace across the Perth metropolitan area. This saves you the inconvenience of taking your vehicle to a workshop.
Why is my car air conditioning blowing warm air?
Warm air can be caused by several problems, including low refrigerant, refrigerant leaks, compressor faults, electrical problems or other air conditioning system failures. Proper diagnosis helps identify the cause before repairs are recommended.
