Why Your Air Conditioner is Making Weird Noises

air-conditioner-techWe’re headed for some decently warm weather over the next couple of weeks, which means you’re probably going to be using your air conditioner at least a little bit to stay comfortable. While you’re using it, you should listen for any noises that your system doesn’t normally make. Unusual noises are often one of the first signs that something isn’t working properly with the air conditioner. What exactly is wrong with the system, and how bad it is, depends on the sound being generated.

Grinding

Inside your air conditioner is a part called the air handler, which is responsible for circulating air through the home while the system is operating. The air handler generates a lot of friction while it’s running, so it uses oiled bearings to help keep things running smoothly. These bearings do their job well, but they don’t last forever. As the bearings wear down, the friction on the air handler increases until it eventually starts to make a loud grinding sound while the air conditioner is on. If you hear your air conditioner making a grinding sound while it’s running, you need to make sure that you call for repairs right away. If the bearings are not replaced in time, the air handler will overheat and burn out. Trust us when we say you’d much rather replace worn out bearings than an entire air handler.

Hissing/Bubbling

If you hear hissing and bubbling coming from your air conditioner, that means you likely have bubbles in the refrigerant line. Which means you have a leak. Refrigerant leaks slowly cripple the air conditioner by draining it of the fluid it needs to cool the home. The lower the refrigerant level in the system drops, the less ability the air conditioner will have to properly cool your home. Eventually, the refrigerant level will drop so low that the system will break down completely. So make sure you call for a technician if you notice this problem.

Short Cycling

When the air conditioner keeps turning itself off before it can complete a full cooling cycle, that’s called short cycling. This is perhaps one of the most serious issues an air conditioner can deal with, and has a number of negative consequences in both the short and long term. Short term, short cycling prevents the air conditioner from properly cooling the home. The system is designed to operate in full cooling cycles, and not being able to do that cuts into its cooling ability.

Long term, short cycling increases the amount of wear and tear the air conditioner accumulates in a short period of time. The longer the air conditioner short cycles, the greater the chance that it will develop problems of various kinds. It will also have its effective lifespan shortened by a number of years. If your air conditioner is doing this, have a technician take a look at it as soon as possible.
