Four Signs of Automotive AC Problems

Few things are more frustrating than a faulty air conditioning system in your car, especially in the heat of summer. Though it is not a necessity for operating your vehicle, it’s a luxury few would like to do without. Obviously, the easiest way to know you have an AC problem is if you don’t have cold (or hot) air. However, you can easily detect cooling problems before your car stops blowing cold air.

1. Leaking Refrigerant

The most telltale sign that you have an automotive air conditioning problem is leaking coolant. If you notice a pool of coolant underneath your vehicle, that indicates an AC system leak.

2. Noises

If you can hear rattling when you turn on the air conditioning, this probably indicates an air conditioning problem in your vehicle. This can point to an air compressor problem or it could just be that you have debris clogging your system.

Water Stains

Similar to the leaking refrigerant, if you notice water stains inside your vehicle, you could have a problem. This means the drain is damaged or clogged, backing up the flow into the vehicle. If you can see spots under the dash or floor mats, you need to take your car to a repair shop.


If you can smell a foul odor when you turn on your AC, there is a problem. You could have mold growing in your AC system and it needs inspecting immediately.
Your car’s air conditioning system is more complicated than you think. Leaving it uninspected can lead to major repairs. Make sure your vehicle’s AC system is at optimum functionality by bringing it to Walnut Creek Import Service in Walnut Creek, California.
