For the most part, the sound of an air conditioner making noise is a normal part of life in Texas. You expect that when the AC kicks on, you’ll hear that familiar low hum and some moving air. But when your air conditioning system isn’t running properly, you may hear sounds that are unusual.
Here are six odd air conditioner noises that can mean it’s time to schedule service from the pros:
1. Gurgling
Gurgling is one of the more concerning noises you can hear. When your AC sounds like there’s a bubbling cauldron in the walls, it likely means the system is leaking refrigerant.
This leak might be in a relatively innocuous location, but if the leak is in an area where people frequent, then there is an exposure risk. Too much contact with refrigerant can lead to nausea, vomiting, and respiratory problems. The leak can also lead to system inefficiency and cause serious damage to your AC unit.
2. Loud Clicking
You’ll hear soft clicks from healthy systems, particularly when the set temperature is reached and the system powers down. However, if you hear loud clicks when the system is trying to start up, that can be a sign that the motor capacitor is dying. Once the capacitor dies, the motor won’t be able to start.
3. Whistling or Screeching
When an air conditioner makes whooshing noises, it may simply be an indicator of moving air, which is what you should expect to hear from an AC. However, whistling and screeching noises can be due to loose or worn belts or moving parts that need lubrication.
If you let the whistling or screeching continue, the belts can snap, the motor can seize, or the compressor could fail. It’s important to call for service immediately if you hear either of these sounds.
4. Rattling and Clattering
The source of an air conditioner rattling noise is often a moving part that’s become loose. This can cause major problems if the part breaks or falls off entirely. The sound can also come from debris collecting on the condenser unit’s grill. Either way, repair is needed as soon as possible.
5. Banging Sounds
If a large part, such as a fan or entire motor should become loose, it can move around significantly. Hearing a loud banging noise in air conditioner systems is typically a sure sign that an immediate shut down is necessary.
6. Buzzing
When motors get stuck, the cause can be a frozen system that just needs to thaw. It could also be more serious, such as debris preventing a motor from turning or loose wires.
Don’t ignore this air conditioner noise, as electrical problems can and do lead to fires.
