As you begin using your air conditioner this spring and summer to combat the heat in Spring, TX, you may notice an unusual sound. Maybe it’s a banging, whirring, grinding, or a clanging, rattling or humming; but whatever it is, it doesn’t sound right. It’s important to take note of such sounds so that you can take the necessary steps to repair what’s ailing your cooling system. Ignoring problems now may make for additional repairs or even premature replacement later. In this post, the experts here have assembled a list of common air conditioning sounds and what they may mean. There’s no substitute for hands-on professional diagnosis, however, so if you’re concerned about your cooling system, and you think you may need air conditioning repair in Spring, TX, call KAC Express today!

Let’s review the sounds to look out for:

• Squealing. If your indoor air handler seems to squeal upon start-up, there is probably a loose belt. The belt connects the motor to the fan mechanism not unlike the radiator fan belt in your car. When it becomes loose, worn, or damaged, it can emit a high-pitched squealing. It’s not only irritating—it can also indicate a serious problem that needs professional attention.
• Buzzing. If you notice a strange buzzing in or around your AC units, then it may indicate an electrical problem. There might be a loose connection somewhere, or possibly evidence that there is an electrical arcing issue. Both can be potentially hazardous, so it’s important to take care of it as soon as possible.
• Hissing. A hissing sound often indicates an air leak of some kind. If it occurs in or around the ductwork, then it can often indicate a crack or loose-fitting duct, but if it occurs near or around the outdoor or indoor AC unit itself, the problem may be slightly more complicated to diagnose. There might be a leak in your internal valve, too much compressor pressure that has caused a refrigerant gas leak, or a problem with your expansion valve.

Diagnosing air conditioning sounds is notoriously difficult and should be left to a professional. For Spring, TX air conditioning repair, call KAC Express today!
