Keep It Cool

Broken air conditioning in a vehicle can leave you very uncomfortable and agitated in hot weather. Boy, is it Hot. Prompt repair is critical to your total cost, since AC problems get worse the longer they go unchecked.
Early detection of AC problems is critical. Some common symptoms include:

Weak Airflow

Weak air flow is an indication of AC problems to come. Common reasons your AC system might be having a hard time providing ice cold air include:

o   Loose AC Compressor Belt
o   Mold or mildew accumulation from the residual moisture of the AC system
o   Loose or broken seals
o   Broken ventilation fan

Warm Air From Your Car AC

Warmer than normal air coming out of your vents is another indicator of AC problems that will eventually lead to AC system failure, commonly caused by:

o   A clog in the refrigerant charging hose or the expansion tube
o   Failure in the blower motor or blower motor resistor
o   Vacuum leaks
o   Freon leak because of a failed hose, seal, or O-ring
o   Failure in the compressor or compressor clutch
o   Damage to the evaporator or condenser of the system
o   Failure of the control module, a fuse, switch, relay or the solenoid

Bad Odor

If your AC system is putting out a foul odor, it is usually one of two issues. Either the air cabin filter is old or dirty, or the evaporator case is moldy. Either way, we can fix it.

AC Air Flow is Cool, Then Becomes Warm

Sometimes, your car’s air conditioning may start running well, cooling off your car as you expect it to. But then, it starts to warm up. This could be due to:

o   A faulty compressor clutch
o   A shorted fuse
o   A refrigerant leak (treat this ASAP, since refrigerant can become corrosive once mixed with moisture)
o   A clogged expansion valve

Avoid Car AC Repairs with Regular Maintenance

The best way to prevent needing car AC repair is regular inspection and maintenance. There are several ways to check the air conditioning system for efficiency or potential failures, including:

o   Visual inspection of cooling fans, water pump, radiator, belts, hoses, clamps, and caps
o   Combustion leak test
o   Fluid check for coolant leakage
o   Injection of a black light tracer dye to detect leakage points
o   Radiator cap pressure test
It is important to have your AC system inspected regularly. This will help detect problems before they start to ruin the AC system of your car and cause more expensive problems. In addition to the tests above, occasional flushing of the cooling system can be helpful.

Routine maintenance can help prevent AC problems. When you need maintenance or when you need car AC repair, turn to AutoAid for help. AutoAid technicians are specialized in AC repair for gas-powered and hybrid vehicles. You can even schedule an appointment online.
