Why Is My AC System in Tallahassee, FL, Making Weird Noises?

Sweltering spring and summer temperatures in Tallahassee, FL, can make it virtually impossible to live in the area without an air conditioner. Naturally, if your AC system suddenly starts making weird noises that it didn’t make before, this can be cause for alarm, especially since most recently built central air conditioners produce little to no noise. Here’s some important information about what the various types of noises coming from your AC system might mean and what to do about them.

Loud Noises Like Banging or Clanking

In general, loud banging, hammering, rattling or clanking noises are all signs that some part in your AC system is defective or malfunctioning. A banging noise signals that something is wrong with the compressor, whereas loud buzzing or clanking may indicate that a fan blade has come loose and is repeatedly striking other parts of the system. Rattling noises usually mean that debris like twigs or leaves is caught in your system.

Loud noises like these are often signs of serious underlying issues and likely require the repair services of a trained service technician to resolve. Without a functioning compressor, your AC system won’t be able to properly cool hot and humid air.

Quieter Noises Like Humming and Whirring

AC systems can also emit a variety of quieter and less jarring sounds, like humming, whistling, whirring or pulsating noises. These could also indicate underlying issues with your system but are generally less serious.

For example, a humming noise can be completely normal, at most pointing to a minor issue caused by loose refrigerant piping. Alternatively, it can be a sign of more serious underlying electrical issues like a defective contactor relay switch.

Rhythmic pulsating sounds can signal loose components, but they don’t necessarily imply any problem at all. A whistling or squealing noise could mean that there’s either a refrigerant leak or an air pressure issue. Common causes of whirring noises include issues ranging from defective fan blades to debris trapped inside the unit.
