Common Faulty A/C Symptoms
Generally, auto air conditioners are fast, easy and inexpensive to fix. Most car air conditioning problems are coolant-related, and may often be as simple as getting a coolant flush, refill or fixed leak. Here are a few of the problems most commonly found in auto air conditioners:
Coolant and/or Refrigerant Leaks
This generally applies to older, less computerized vehicles. Refrigerant can run out on its own over the course of time, or leaks may have developed in the car’s AC compressor or one of its hoses. If your vehicle has never had a coolant flush or refill and it’s pushing 150,000 miles or more, it’s probably time.
Noisy AC Compressor
Noises that occur when your car’s AC is turned on can come from minor engine noises or hoses, but they could also be symptoms of problems with the compressor. If the problem is the AC compressor, it will likely have to be replaced.
When a car’s AC blows out air with sporadic temperatures, it’s often likely that moisture is building up in one of the hoses or assemblies, causing ice to accumulate and clog. Removing ice from a car’s air conditioning assembly is a short and easy procedure.
Faulty Car Electrical System
A weak car battery can cause your auto air conditioner to function weakly or not at all. Car batteries need to have enough voltage to trigger the AC compressor, and while it may be strong enough to run the rest of your car, it may still be too weak to run your car’s air conditioning.
Funky smells emanating from your car’s air conditioning vents are likely caused by a bacteria buildup in the evaporator. Good auto mechanics will have the proper tools to flush the evaporator out quickly and without much cost.
If one of these symptoms applies to your car’s air conditioning system, it’s probably time to have it inspected by a mechanic. Caught early, most auto air conditioning problems are fairly easy and inexpensive to fix.
