Why Your Air Conditioner is Making Suspicious Noises

air-conditionerIt’s getting close to air conditioning season. If you’re not already putting yours through its paces to keep your home cool every day, you will be soon. While you’re using your air conditioner on a daily basis, you should keep an eye out for signs that the system is experiencing any kind of trouble. If you can identify problems with your air conditioner quickly enough, you’ll be able to get it repaired before any real damage can be done.

One of the most common signs that your air conditioner is not functioning the way it should be is if it is making odd noises. What exactly the problem is, and how serious it is, will depend on the noise the system is making. Let’s have a look at some of the more common noises that indicate a problem with the air conditioner.


Inside the air conditioner is a part called the air handler. The air handler’s job is to circulate air through the ducts while the air conditioner is running. Without a properly functioning air handler, the air conditioner won’t be able to actually cool the home because it won’t be able to circulate the air. Inside the air handler motor are a series of bearings, which are meant to reduce friction on the system while it’s operating. Over time, the bearings can wear down and friction on the motor will increase. This can eventually reach a point that the motor produces a loud grinding sound while the air conditioner is on. Call for repairs if you hear this sound. The bearings will need to be replaced before the air handler motor burns out entirely.


If you hear a sound like the air being let out of a tire coming from your air conditioner, that means you likely have a leak in your refrigerant line. The air conditioner relies entirely on its refrigerant to cool the air in the home. As the refrigerant level in the air conditioner drops, so too will the system’s cooling ability. Eventually, the air conditioner may break down entirely. Make sure that you call for repairs if you notice that your air conditioner is hissing, especially if it’s also leaking fluids.

Short Cycling

Short cycling is when the air conditioner turns itself on and off every few minutes instead of completing a full cooling cycle. It can be caused by an electrical problem, but also by a damaged or defective compressor. Short cycling prevents the air conditioner from cooling properly, but it also increases the rate at which the system wears down over time. If not addressed quickly enough, it can shorten the air conditioner’s lifespan by a number of years. Make sure that you have a professional take a look at the system if it’s doing this.
