Summer is here, and with it comes an awful lot of wear and tear on the air conditioning system. If you want to keep your air conditioner in top condition, you should call for repairs as soon as you notice signs of a problem with the system. One of the first signs that your air conditioner is in trouble is strange noises coming from the system. Let’s take a look at some of the noises you should listen for this summer, and what they indicate.
A grinding sound is an indication that the oiled bearings in your air conditioner’s air handler are wearing down. The air handler is the part of the air conditioning system responsible for circulating air throughout the home during operation. This generates a lot of friction on the system, which is what the bearings are for. If you hear a grinding sound coming from your air conditioner, you need to call for repairs as soon as possible. Otherwise, the bearings might fail completely and the air handler will burn out.
Bubbling and hissing noises are typically due to air bubbles forming in the refrigerant line. The air conditioner needs refrigerant in order to cool the home. It recycles refrigerant back and forth between liquid and gaseous forms to move heat out of the house. If a leak develops in the refrigerant line, it will drain the system of the fluid that it needs to operate properly. This will cause a steady decline in output, followed by an eventual breakdown of the entire system. Refrigerant leaks must be repaired as soon as possible, or else the entire air conditioner will be threatened.
