4 Causes of That Bad Smell Coming From Your AC System

With summer temperatures in Chatsworth, GA, climbing into the 90s and even higher, you want to ensure your air conditioner runs well. No one wants to come home to bad smells emanating from their air conditioner. Here are four possible causes of the bad smell coming from your AC system:

Filter Clog

Air conditioners can easily develop clogs caused by dirt and other debris that stick to the filter. When this happens, you’ll likely notice a musty odor that smells like dirty feet. Changing the filter and cleaning the air conditioner can help. Change your filter every filter every month, and schedule AC maintenance seasonally.

Refrigerant Leak

Your AC system may produce an odor that smells like the exhaust that comes from your car. This often happens when you have a refrigerant leak. An AC maintenance plan helps you learn about these problems before you notice the odor.

Burning Wiring

When you turn the AC system on or let it run for a while, you may notice a burning odor. That’s a clear sign of a burning wiring or part in the air conditioning system. You should always shut it off and call a pro to find out what wiring or parts you need to replace.

Circuit Board Short

All air conditioners have circuit boards that send signals to different parts of the AC system. When the circuit board has a short, it’ll smell like gun powder. Gun powder smells can also relate to a short in the fan motor.

Don’t ignore bad smells coming from your AC system. They could be a sign of a serious and dangerous problem. Call Dalton Heating & Air today to have a pro check your air conditioner and find out what AC repairs you need. We’re here to give you peace of mind.
