The unusual noises that warn of something wrong that may require repairs or basic troubleshooting is a common topic about air conditioners that we like to discuss from time to time. There is a lot of mention of these warning air conditioner warning noises. However, what is rarely touched on, is the sounds that are normally made when the AC is operating. The sounds you should expect to hear from your air conditioner as it functions. In an effort to help you better identify the strange sounds, we at Air Supply Air Conditioning & Heating would like to discuss the natural noises you should be hearing from the AC.

AC Compressor Humming

When the compressor in the condenser cabinet starts to hum it indicates that the air conditioner is performing its job, and this hum is the most important noise you’ll hear from an air conditioner. The start of the air conditioner’s cooling cycle is signaled with the light hum. The compressor’s motor starts so it can put the liquid refrigerant under pressure and change it to a hot gas so it will circulate to carry out heat exchange when the AC has received a signal from the thermostat that the interior of the house requires cooling. You can expect to feel cool air coming from the system after the compressor turns on. The compressor may be malfunctioning if you don’t hear it.

AC Making a Water Noise

This is a sound you’ll hear from the inside components of the AC. It isn’t constant, but something that you’ll hear at periodic intervals. If you’ve ever watched a window AC at work from the outside, you’ll notice water dripping from it. This is the same condensate moisture you hear from your central air conditioner, although the moisture isn’t dripping into your house but exiting to the outside through a drainage system. When you hear water from the AC, it’s the drainage system removing the moisture that collects along the evaporator coil.

Blowing Fan Sound

The blower fan pushing air through the AC and then into the ductwork when you hear the main sound, you’ll hear your air conditioner make from the inside of the house. One sound that will turn into the white noise of the summer season should be a gentle and steady sound.

AC Clicking Noise

You will hear several clicking sounds coming from it when an AC finishes its cooling cycle. A standard sound of machinery stopping, such as the compressor and motors, is the clicking. However, failing capacitors or loose parts and other clicking sounds can indicate trouble. You’ll become accustomed to what “normal” clicking sounds like as you listen to your AC as it cycles down.

Air Ducts Rattling

The rest of the ductwork may be constructed of flexible plastic or duct board, and the ductwork exiting from the central HVAC cabinet is made from metal. The metal may make a rattling noise when the air conditioner turns on because metal changes shape as it’s heated and cooled. The rattling ducts should not continue for too long, so if it does, it can point to loose ductwork.
