What Are the Signs of a Bad AC Condenser?

During summers, the high temperatures in Minneapolis range between 80° F and 115° F. When the heat becomes unbearable, most families turn to their air conditioners. If you live in Minneapolis, you will do well in checking your air conditioner before the summer commences. While you can get some ac condenser failure problems, you can be in for trouble if you are stuck with a failing AC condenser.

An AC condenser is an integral part of your cooling unit. It is responsible for cooling down and, after that condensing the incoming refrigerant into a liquid form. The AC condenser comprises many moving and stationary parts such as fans, tubes, motors, a compressor, and a circuit board. A bad AC condenser can cause a number of problems. If your AC condenser is about to fail, you are bound to notice the following signs of a bad condenser. So if you are thinking how to know if your ac condenser is bad here are:

3 Symptoms You Have a Bad Air Conditioner Condenser

  1. Lukewarm Air: One of the main AC condenser failure symptoms has failed or beginning to die is warm air coming out of the vents. This can happen when the condenser is too hot and can no longer convert the incoming refrigerant into a liquid. Since the fans in the condenser unit are designed to prevent it from getting too hot, warm air coming out of the vents is a tell-tale sign that something is wrong with your cooling unit.
  2. Loud Noises: Any time your air conditioner makes loud rattling noises, the odds are you have to call in a technician to diagnose the problem. While loud noises can indicate other issues, there is every likelihood that your condenser may need attention. Do not overlook any strange noises, or put them away for later.
