1933 saw the first air conditioners installed in cars as an aftermarket item and it wasn’t until 1939 that the Packard Motor Car Company offered the cooling device as a factory option.  Many summers have past since then and A/C has become a standard option on just about every vehicle in the world.

Now, we will save you the boring lecture, and jump right to the cliff notes, on how this life changing system works.  With the summer heat upon us, here are a few signs that your A/C system may be in need of repair.

1. If the air coming out of the vents isn’t as cool as you remember
2. If you are unable to remove moisture from the windows with the defrost function
3. If you hear a belt squeal or knocking under the hood around the A/C components
4. If you do not hear any components turn on under the hood, or the engine RPM dip, when you turn on the A/C
