However, air conditioning trouble doesn't have to come as a surprise. If you can learn to recognize the signs of trouble early, you might be able to call in the professionals before things turn sour. On my blog, you will be able to read through loads of helpful information on HVAC, so that you can detect trouble before it ruins your sleep.

Sounds Like A/C Trouble: 5 Noises To Pay Attention To

Blog

There's more than meets the eye when it comes to diagnosing potential problems with your air conditioner. Your ears are also a great tool for identifying issues that could degrade your air conditioner's performance or even sideline your unit altogether. By listening closely to your A/C system, you can avoid stressful breakdowns and invest in preemptive maintenance before the worst happens to it.

So, what exactly should you be keeping an ear out for? The following describes several sounds that could signal trouble ahead for your A/C system.

1. Rattling

If your air conditioner develops a constant rattling noise, the culprit is usually a loose screw or a hard piece of debris that's trapped within the A/C unit. These rattling noises can be further aggravated by vibrations caused by loose or otherwise improperly installed components. Once you've pinpointed the source of the noise, correcting it is usually a matter of removing the offending debris or tightening up a few loose fasteners.

2. Scraping

Metal-on-metal contact between components inside of your A/C unit can also cause tell-tale scraping noises. Such noises can occur when the blower fan loses alignment due to a loose fastener or accidental damage. Bent fan blades can also cause scraping noises if they strike the metal fan housing.

3. Buzzing

A loud buzzing sound coming from your A/C system could mean a variety of issues, including an electrical short caused by a failing component. Poor blower fan balance can also generate enough vibration to produce buzzing noises during A/C operation. Last but not least, buzzing noises could also indicate impending compressor failure.

4. Hissing

If you hear hissing noises from your A/C system, have your air conditioning repair technician perform a checkup as soon as possible. The noises you're hearing could be the result of a refrigerant leak in progress. Losing refrigerant not only puts your A/C system at risk of breaking down, but the release of refrigerant into the atmosphere also contributes to the degradation of the ozone layer.

Hissing noises can also stem from leaky ductwork. An ongoing leak can cause your A/C system to work harder to compensate for the air loss, resulting in higher energy consumption and faster wear and tear on A/C components.

5. High-Pitched Squealing

If your A/C system squeals relentlessly after startup, you may have a bad blower fan belt on your hands. Rubber belts can deteriorate with age and use, resulting in cracks, glazing and an overall loss in flexibility that leads to belt squeal. Worn bearings can also produce high-pitched squealing due to the metal-on-metal contact.
