Auto A/C & Heating

Ever wondered how the air conditioning system in your car works? Here is a brief description of its operation. First you need a sealed system with a gas inside. The gas used is freon. The freon is pressurized by a compressor and sent through a series of tubes both inside and outside the car. It first will journey out of the compressor to the condenser which is located in the grill of the car. The cooling fan and the air movement while driving is used to remove the heat from the gas. The freon will continue to travel out of the condenser to a pressure reducing device. Since freon has a pressure and temperature relationship, the temperature of the freon reduces drastically. This cold freon now travels to the interior of the car and enters an evaporator. The fan will blow across this unit thereby blowing cold air inside the cabin of the vehicle. As the freon leaves the evaporator it heads back to the compressor to start the journey all over.

Car A/C or Heating Not Working?

The reasons for your A/C System to stop working are many. It could be as simple as low freon or a complicated computer control problem. Below is a list of a few of the possible problems that could cause your A/C System not to work properly.

  • Too low or high freon charge
  • HVAC control head malfunction
  • Compressor internal problems
  • H-Valve restrictions or operation
  • Fan circuit or operation
  • Blend door operation
  • Ambient air temperature readings
  • Seals or gaskets leaking

These are just a few of the many causes that would result in your A/C performance dropping below your expectations. We would love the opportunity to service your vehicle and fix this problem.

A/C not blowing as cold as it used to? Don’t sweat it. If your car’s air conditioning system isn’t working like you think it should, you’ve come to the right place. ProAuto has ASE certified technicians that can solve your problem.. Some common A/C problems our customers bring to us are:
