There are a few common things you might notice when your car’s air conditioner needs a recharge service or repair:
- Hot Air Blowing
This is most commonly due to a refrigerant leak. A quick check you do at home is to start the car, turn on the a/c and see if the compressor comes on. If it does not, we know you have an electrical problem or a refrigerant leak. If it does, then it is likely you have a control or circulation issue. Another cause could be a control problem that is causing the heat to turn on.
- No Air Blowing
A blown fuse is often the cause of this problem. Another possible, but rare reason, is a faulty dashboard fan or blower switch. If replacing the fuse does not repair the problem, you will need a certified electrician to diagnose the root cause of the problem.
- Strange Smell
This problem is characterized by a musty or mildew odor when the fan is turned on. This condition can indicate that mold or mildew is growing in the evaporator box requiring a cleaning procedure to eliminate this smell.
- Odd Noises
A drive belt makes the air conditioning compressor turn, and that keeps the cooling refrigerant circulating. If the belt is worn, stretched or cracked it can slip or break which can make noise or stop the compressor altogether. When this happens, circulation stops and the air conditioner quits cooling. It can also cause other serious damage to other engine systems.
