How to Deal With Noisy AC Unit

Having an air conditioning unit in your home is very important especially if you live in a place that experiences extreme heat at some point during the year. But the AC may break at some point, particularly if it has started becoming old. One of the most common problems that AC units usually have is noise. The noise can have many causes depending on the brand and model of the unit. You should not ignore it if you start hearing it from your system since it is usually a sign that something is amiss or is in the process of going amiss.

One of the places in the AC unit where the noise is likely to emanate from is the fan. For the fan of the unit to work properly, you will need to make sure that it kept clean and maintained well. If it is producing a harsh humming or rattling noise, the fan may be dirty or lose. To fix this problem, you will need to open the cabinet of the AC and then locate the fan. If there is any debris on or around its blades, you will need to remove them. There may be insulation or other items that may have fallen into the unit and are also causing it to be noisy. You will need to locate them and remove them.

If you open the AC cabinet and find that there is no debris, you will need to check if the blades are loose. If so, you will need to use a screw driver to tighten the screw at the hub. Also check to make sure that the blades do not have bends. A slight bend on a blade may cause it to touch the unit, something that will in turn cause the unit to produce a lot of noise. When bending the blades back into place, you will need to be careful not to break them.

Another possible cause of noise in the AC unit is a motor that needs lubrication. If the motor is not lubricated, you will hear a grinding or humming noise coming from it. You can prevent the noise that comes from this part by oiling the AC unit at the beginning of every summer. You should also check the coil fins in the AC unit and make sure that they are not clogged with dirt. If they are clogged, you will need to use a vacuum cleaner that has a brush attachment to get rid of that dirt. The coils may also be bent, so you will need to use a proper tool called the fin comb to straighten them.

Loose screws in the air conditioner might also cause it become noisy. Since the AC vibrates when it is working, there is a chance that its screws may become loose. You will therefore need to use a screw driver to tighten those screws so that the AC can be held properly in place to prevent it from producing a rattling noise.
