It’s no secret that today’s air conditioning units are much more advanced than early models, especially in terms of quiet operation. You can find ACs today that register below 55 decibels while they’re running, thanks to their two-stage compressors. This form of sound-dampening technology allows you to hear any unusual noises coming from these units. When this happens, you need to seek the expertise of an AC repair professional to help diagnose the problem.
Mechanical Technologies, a leading HVAC contractor in the local area, discusses some of the strange sounds that can be heard coming from air conditioning units, and the meaning behind each of them.
A buzzing sound could mean a few different things. The air filters of the AC unit could be filled with dust and debris, which means that they’ll need to be cleaned or replaced right away. Another possibility is that the outdoor unit could have loose components, such as the blades of the fan motor, or the copper lines that run from the outside to the inside unit could be rubbing against something. Furthermore, the blower could be bad or out of balance, or the condenser coil may need to be cleaned.
The clicks you may be hearing when the AC turns on or off are perfectly normal. This noise is usually only a bad sign if it happens even when the unit is in operation, which could mean a failing thermostat or a defective control panel. You’ll want to hire an air conditioner service pro to handle this situation, as both instances involve electrical components.
Squeaks, squeals and rattles may occur as a result of outdoor fan motors and indoor blower motors going bad. These noises can be heard throughout the duct system, and may be a normal occurrence or something new. To make certain, have the technician examine your AC to see if the squealing is due to a malfunction or is rather a sign that one of the components requires immediate repair.
