In the middle of a heat wave is a horrible time to realize that you should've replaced your old a/c condenser. However, more often than not, this is the time most air conditioners decide to quit working. You can avoid getting stuck without air conditioning if you stay ahead of the game by regularly checking your air conditioning unit and replacing your MINI a/c condenser when it's time. The a/c condenser is a vital component of your air conditioning system. It takes in hot Freon gas and cools it down while changing it into liquid. Then, the cold liquid Freon is sent to various parts of the air conditioner where it returns to its former gaseous state. This cold gas is pushed through your ventilation system and the cabin of the vehicle cools down gradually. Whenever you think that your a/c isn't working as well as it used to, make sure the first thing you check is the a/c condenser.
