Why is my air conditioner making this much noise? Troubleshooting Tips.

Is your air conditioner sounding more like a rock concert than a cooling oasis? Don’t let noisy AC woes disrupt your summer comfort! At Alliance Energy Source, we understand the importance of a serene indoor environment, especially when temperatures soar. If your AC is making a racket, it could be a sign of underlying issues that need attention. Let’s dive into some common AC noises and what they might indicate:

1. Humming: While a gentle hum is expected, unusually loud humming could signal issues with the fan. Cleaning might suffice, but bent blades or a failing motor could be culprits.

2. Buzzing/Popping: These noises often point to electrical problems like faulty relays or loose wiring. Electrical issues pose risks, so it’s crucial to shut off your AC and seek professional help promptly.

3. Banging/Clanking/Rattling: Sounds from the outdoor unit suggest problems with the fan or blower. Off-balance components or loose parts could be the cause.

4. Clicking: Normal during startup, continuous clicking might indicate faulty controls or a malfunctioning thermostat.

5. Bubbling/Gurgling: These sounds could indicate issues with condensate drainage or a refrigerant leak, both of which require attention.

6. Squealing: Typically from the indoor unit, it often signifies a worn-out fan belt or motor malfunction. Prompt action is needed to prevent further damage.

7. Whistling: Poor airflow due to dirty filters or duct issues can result in whistling sounds. Cleaning filters or addressing duct problems can resolve this issue.

8. Hissing: A loud hissing sound could signal a high-pressure build-up in the compressor, which is dangerous. Immediate shutdown and professional intervention are necessary.

Regular maintenance checkups are crucial for ensuring your AC operates smoothly and quietly. If your AC is creating a symphony of sounds, don’t hesitate to reach out to us. Our expert technicians will troubleshoot the issue, identify the root cause, and restore peace to your indoor environment.

Your comfort and safety are our priorities, so let’s silence those noisy AC woes together! Contact Alliance Energy Source for reliable AC repair and maintenance services.

5. Bubbling/gurgling A bubbling AC sounds very similar to gurgling liquid, and that’s exactly what’s going on inside of it. The bubbling sound either comes from condensate gurgling as it passes through the drain line, or from a refrigerant leak. 6. Squealing Squealing noises often stem from your air conditioner’s indoor unit. You will hear these high-pitched sounds when the unit is running, and this usually means that there is a problem with the fan belt. Over time, parts like these can become worn out or misaligned, leading to a motor malfunction. If you have an older unit which uses a belt system, this is most likely the problem, and you will hear sounds both inside and outside your home. Most of the newer units don’t use a belt system, so in that case, the fault could be in the condenser’s fan motor. If you hear such squealing noises, you have to get the worn-out blower fan motor bearings or belt of your ACfixed, or even replaced. 7. Whistling Usually, a whistling sound means your air conditioner isn’t getting enough airflow. This could be due to dirty/clogged air filters (especially if you notice that your AC has stopped blowing cold air). You can fix this issue yourself by cleaning the filters. If that doesn’t work, it means that the problem is probably because of your ductworks. Your HVAC ducts could’ve developed cracks and leaks, or the duct size isn’t suitable for your AC equipment. Blocked return vents, closed dampers or too many closed doors are all also causes of a lack of airflow. 8. Hissing Hissing noises from your air conditioner is something you should always be cautious about. This loud hissing sound is heard for about 10 – 15 minutes as soon as your AC turns on. The most common reason is a high-pressure build-up in the compressor, and this is extremely dangerous. It is crucial to switch off your AC and call us immediately.
