If your car or truck is blowing hot air, you should get it checked out.  If you’re thinking about fixing it yourself, here are some common problem areas to check.

  • Low Refrigerant – The refrigerant in your vehicle could below.  This is a common problem.  If this is the case, you’ll need to get a refill.  Also be sure to check for any leaks.
  • Compressor Issues – The compressor is a pump that helps separate the high-pressure and low-pressure sides of the A/C system.  If there’s a burning smell under your dashboard when the A/C is running, you may have compressor issues.
  • Evaporator Issues – The evaporator helps to remove hot air from your vehicle.  It also helps to remove any heat from the refrigerant.  Many times there can be a leak in the evaporator, which causes cooling issues.
  • Condenser Issues – The condenser looks similar to your car’s radiator.  The condenser helps to cool hot gases traveling in your A/C system in to a liquid.
