Is your air conditioner making strange noises? While some sounds are normal, others can signal trouble. If you hear anything unusual, your AC might need professional attention before minor issues turn into costly AC repairs.
Here’s a guide to common AC noises and what they mean.
Normal AC Sounds
Before we dive into the concerning noises, let’s talk about what’s normal.
- Soft clicking – Your AC clicks when it turns on and off. That’s just the thermostat doing its job.
- Whooshing – The gentle sound of air moving through your vents is nothing to worry about.
- Low humming – A quiet hum means your AC is running smoothly.
AC Noises You Shouldn’t Ignore
1. Banging or Clanking
Hearing a loud banging noise? That could mean a loose or broken part inside your compressor. If ignored, it can cause serious damage to your system.
2. Buzzing
A buzzing sound could point to electrical problems, like faulty wiring or a failing capacitor. Turn off your AC immediately and call a professional to avoid the risk of fire.
3. Screeching or Squealing
A high-pitched screeching sound often means a worn-out belt or an issue with the motor bearings. This problem can worsen over time, so it’s best to have it checked sooner rather than later.
4. Hissing
A hissing noise may indicate a refrigerant leak, which can affect your AC’s cooling efficiency. Refrigerant leaks also pose health risks, so don’t delay calling a technician.
5. Rattling
If your AC sounds like it’s shaking, debris might be stuck in the unit, or some components could be coming loose. Ignoring it may lead to bigger problems, so a quick inspection is a good idea.
6. Popping
Hearing popping sounds in your home? It might not be your AC itself but your ductwork expanding and contracting due to temperature changes. While this isn’t an emergency, you should have your ducts inspected to ensure efficiency.
7. Gurgling
A bubbling or gurgling noise often signals a drainage issue or an airlock in the refrigerant line. If you hear this sound, it’s time to call for service before your AC stops working.
