If you have a loud AC unit on your hands, we’re the ones to call to quickly get the problem resolved and restore your air conditioner to its optimal performance level.
Why Your Air Conditioner is Making Loud Noises
Most loud noises from air conditioners should be handled by a professional, but if you’re curious about what’s causing them, here’s the source of the five most common ones:
- Banging noises from the outdoor unit are most likely from the compressor, the component responsible for circulating refrigerant. Normal wear and tear on interior parts can cause them to loosen and start creating a loud banging sound. In most cases, this type of problem requires replacing the compressor, but your technician can tell you for sure.
- Buzzing noises inside near the air handler or outdoors by the AC unit are typically the sign of an electrical problem such as a failing motor, loose wiring, a malfunctioning compressor, a broken capacitor, or arcing.
- Clicking noises when the AC unit runs could mean a small object is stuck in the blower fan. If the clicking happens when you try to start the system, but the AC unit won’t turn on, that might mean an electrical issue with the thermostat, capacitor, or compressor.
- Hissing noises can indicate a duct leak, a bad expansion valve, or an air filter that isn’t properly seated. But more times than not, it’s a sign of a refrigerant leak.
- Screeching and squealing noises that sound like metal on metal are usually caused by a bad compressor, a faulty blower motor, or a bad outdoor fan motor. If the loud noise is coming from the outside unit, it’s probably caused by a bad compressor or faulty fan motor. If it’s indoors, it’s likely the blower fan motor.
Repairing Noisy Air Conditioners
In some cases, an AC unit is beyond repair once it starts making loud noises. However, most of the time, the unit will only need a repair or two to begin functioning quietly again. If the unit is old, you might want to discuss the possibility of replacing it with a newer, more cost-effective model.
