Why Is Your Air Conditioner So Loud?

Having an air conditioner that is too loud can be annoying and distracting. There are a few common reasons why AC units become noisy. Understanding what causes these sounds and knowing the proper fix can help combat unwanted sounds from your AC and improve the comfort of your home. An air conditioning and heating maintenance packages provider discusses more here.

Possible Reasons Why Your Air Conditioner Is Loud

• You have an old unit. As your AC gets older, components start to wear out and can cause rattling, buzzing or squealing sounds from within the unit.

• You have dirty filters. Dirt and debris on the air filter can restrict air flow, forcing the blower motor to struggle and work harder than usual.

• There are loose parts. A screw that is improperly tightened or an unfastened component could be jiggling and moving around inside the AC unit.

• The coils are dirty. A dirty evaporator coil cannot absorb heat efficiently, causing your compressor to work harder and create more noise.

• The unit size is wrong. An oversized system runs shorter cycles, meaning there are periods when its high-power operation produces sounds that are louder than normal.

• There are refrigerant leaks. Low refrigerant levels may cause certain parts in your unit to vibrate, resulting in loud humming or buzzing noises depending on what component it is affecting.

How to Resolve a Loud Air Conditioner

One way to resolve a loud air conditioner is to change the air filter. Make sure to replace your air filters as the manufacturer recommends or every three months. You should also check for loose components inside and outside of your unit, such as screws, bolts, fan blades and panels. Most importantly, having a professional inspect your unit is crucial. Certain sounds could indicate a more serious issue with the wiring or other internal structures.
