5 Ominous AC System Sounds - HVAC Blog

No air conditioning unit is perfectly quiet, and in a way, that can be a good thing. Though AC units develop problems, their owners do not have to wait until the system seizes to get a clue that it is not running optimally. All they have to do is listen. Below are five sounds that, if you hear them, should prompt you to seek a professional for an inspection.

1. Rattling and Banging

Loud rattling is almost always the result of loose parts in the unit: nuts, bolts, fasteners, etc. It could also be due to a failing motor bearing. Banging usually occurs when either of these problems grows worse.

If the rattling seems to come from outdoors, it may be that leaves and other debris have been caught in the unit. If it comes from indoors, it may point to debris floating in the ductwork.

2. Grinding

This could signify a broken blower fan belt. Possibly, though, the pistons in the compressor are grinding against one another. You won't want to wait until your compressor goes out to get AC repairs. By that time, you might need a new system. Fortunately, [company_name] can provide both repairs and system replacements in the Grove area.

3. Hissing

Continual hissing is usually a sign of an air leak in the ductwork or a refrigerant leak. The latter should be taken care of right away since the refrigerant is harmful to your health and the environment.

4. Clicking

Clicking heard when the AC turns on and off is to be expected. Constant clicking, though, may point to a defective relay or control.

5. Buzzing and Popping

More often than not, this indicates an electrical issue. If something buzzes after you change a setting on the control panel, a broken part may be to blame.
