It is one of the worst feelings to get in your car on a hot day, turn on the A/C, and realize something is horribly wrong.  A/C systems in cars can be complicated and are not easy to fix alone.  A Toyota mechanic in Garden Oaks can assist with auto A/C repair and regular maintenance for an A/C system that will run efficiently on even the hottest days.  Look for these signs to know it is time for A/C repairs or maintenance for your car.

Higher Temperatures

Of course, one of the first signs of an A/C problem is the fact that the A/C won’t cool down your car.  Higher cabin temperatures can indicate a problem with the compressor.  A compressor on the outs can’t regulate the refrigerant flow.  Thus, the A/C can’t blow out cold air like it once did to cool down the temperature inside the car.

Loud Sounds

Another sign that the A/C compressor is failing is loud sounds when turning on the A/C.  A worn out bearing can produce a squealing noise or grinding sound, a seized bearing also makes a grinding noise or can lead to a squealing belt sound.  A/C compressors are complex auto parts that may not require just a simple fix, but rather replacing the entire compressor.  A reliable mechanic in Garden Oaks can determine the nature of the noise and perform complicated A/C repairs to get it up and running once again.

Switch Troubles

Sometimes trying to turn on the A/C won’t work.  The switch can get stuck, either leaving the A/C in a permanently off or on position.  This compressor clutch is a pulley that engages or disengages the compressor as needed.  When it seizes up or breaks off, the compressor can no longer receive engine power.  In some instances, just the clutch can be replaced, but most of the time, the entire compressor will need to be removed and replaced. The A/C compressor is at the center of the entire A/C system.  When this complicated part fails, contact Liberty Garage for all your A/C repair and maintenance needs.
