Summer is almost here, and many people are already relying on their air conditioners to keep cool on a daily basis. If you’re one of those people, you should know that the more you use your air conditioner, the more strain you’ll put on the system. That strain makes it more likely for problems to develop with the air conditioner. So, you should keep a sharp eye out for problems with your air conditioner this summer. Let’s take a look at some common problems that can afflict your air conditioner.
Air conditioner ice may seem like a good thing at first. Air conditioners are supposed to generate cool air, after all. However, ice on your air conditioner is actually a sign that the system is in serious trouble. It’s typically caused by a clogged air filter, which cuts off the flow of warm air to the evaporator coil. This causes the coil to freeze over, which prevents it from siphoning thermal energy from your home’s air. The ice can also spread to other parts of the air conditioner, causing further problems.
The air handler is the part of the air conditioner that circulates air throughout the house. The motor for the air handler is placed under a lot of stress during operation, so to compensate it’s equipped with a number of oiled bearings. These bearings will wear down over time, producing a loud grinding sound when the system is running. If the bearings are not replaced in time, the motor will overheat and burn out. If you hear a loud grinding sound coming from your air conditioner, turn it off and call for repairs as soon as possible. Otherwise, you’ll have to replace a lot more than a few bearings.
