When buying a used car, there are a lot of important factors you must consider. Purchasing a used car you’ll save a lot of money, but you must carefully choose before making the final decision. Many used car sellers often try to hide the cars “imperfections”, from rust spots and scratches to gas mileage and bad tires and brakes. Besides considering factors like gas mileage, model and date of manufacture, a very important factor is also the cars heating and cooling system.

If the car doesn’t get the needed maintenance, it could lead to costly repairs or even the need of getting a completely new A/C system.
