You may be wondering why your air conditioner is so loud. Air conditioners make noise because they are machines with a lot of parts that work hard to keep your place at a comfortable temperature. It’s not unusual for air conditioners to make a variety of unfamiliar sounds. We all know that all air conditioning units make noise when running. Older units are often louder than newer units because the designs have improved over the years to reduce the irritating noise. If you notice weird sounds coming from your newly bought AC, it means there is something wrong with it. Some noises require more quick action.
Here are some reasons for a noisy AC unit:
- Slipped or Old Belt- a slipped belt makes a well-defined squealing noise. The belt connects the compressor to the engine. If the belt is old, it may squeal right before it bites the dust. Should the belt subsequently snap, you will experience an immediate AC breakdown.
- Duct Leaks– a whistling noise is often the sound of a duct leak. If your ducts are leaking, you may be losing precious cool air and energy, which translates to increase your bill.
- Capacitor or Fan Motor Failure– a humming noise, can mean your capacitor is starting to fail. It could simply mean that your fan motor needs a technician for the repair. If you hear a humming sound coming from your system, call a trusted HVAC professional to correctly diagnose the issue.
- Loose Parts– if something is making a rattling noise, the cause is most likely loose parts or screws. The louder the rattling noise, the more out of place the part is, so if you hear loud rattling – don’t take it for granted!
- Electrical Malfunctions– a buzzing noise is a noise that can be attributed to loose connections on the compressor, but it can also occur when the voltage running through your AC unit is at an incorrect amperage. Take good care of it to avoid breakdown.
- Trapped Twigs and Debris– a thumping noise can occur in your outside unit when your yard waste becomes caught in the fan. If you hear clunking or banging, your initial thought before calling an HVAC professional should be to go outside and check your outdoor unit.
- Failing Compressor– a high-pitched screaming noise is not a good sign for your unit. If your compressor has definitely failed, then you need to replace it. However, it may cost too much of your money to go ahead and replace the entire unit.
