When the AC in your Sanford, FL home runs, it’s normal for it to make some noise. However, not every noise your AC might make is normal. Here are three sounds your AC can make that should alarm you.
1. Screeching Noises
It should go without saying, but a screeching noise from your air conditioner is a significant sign of trouble. If the offending sound comes from your AC’s outdoor unit, you likely need a new condenser fan. If it’s coming from your indoor unit, your AC’s blower fan could be the culprit.
Unfortunately, there’s one more component capable of making a screeching sound. It can happen when your AC’s compressor suffers an internal failure. In that case, you may need a new AC installation, as compressor replacements can be costly.
2. Humming or Buzzing Noises
Humming or buzzing sounds coming from your AC is an indication of an electrical problem. A common cause of such noises is a failed or failing contactor switch. It sends power to your AC’s outdoor unit when your thermostat calls for cooling.
Another component that may emit a humming or buzzing noise is a failed capacitor. Capacitors store electricity to provide a jump-start to your AC’s motors. When they fail, your AC’s fans may run slowly or not at all.
3. Hissing Sounds
Hissing sounds are among the worst you can hear from an AC. That’s because they almost always result from a refrigerant leak. Continuing to run your AC with leaking refrigerant can cause permanent damage.
If your AC starts hissing, turn it off immediately. If the hissing comes from your indoor unit, open some windows to ventilate your home. Then, contact us immediately so we can dispatch an HVAC technician to find and fix the leak.
