What is an evaporator core and how much does it cost to replace? Did you know that, scientifically, an air conditioner does not cool the air? It is the evaporator that actually removes the heat from the air so that when you feel the air blowing, it is cool. Replacing the evaporator core is a very labor intensive process. In most cars the entire dashboard must be removed, as you can see in the above photo. But you don't have to worry because we are here to help. Give us a call and we will have your air conditioning working at peak performance and you will have cool air again.
