Reasons Why Your Air Conditioning System May Be Making Loud Noises

If you’ve ever had an air conditioning system in your home, the regular sounds it makes will be familiar to you: the whir of the fan and the hum of the compressor. Anything out of the ordinary, such as loud and unpleasant noises, is usually a sign of a malfunction or an impending one. If left unattended, this problem might eventually cause your air conditioner to cease working entirely. Whatever you do: don’t shrug off loud noises and hope they are only a temporary nuisance. When you decide you need expert help to figure out why your AC has started making loud sounds, contact the staff at Saddleback Plumbing. We offer 24/7 emergency ac repair services, so we can help get your air conditioner working right again at any time of the day.

Some of the usual suspects for an AC making loud noises include:

Low refrigerant charge: The fixed amount of refrigerant in your AC—it’s “charge”—can start to leak, damaging your system’s cooling power. It will also cause a loud noise in the compressor. This sound could also occur if the wrong type of refrigerant is put into the air conditioner, which is why recharging the refrigerant should always be left to HVAC experts.

Loose motor parts: If the moving parts in the motors that run the fans and the compressor suffer damage, they can create unpleasant rattling and grinding sounds. The motors will need repairs and perhaps replacements.

Damaged fan belt: The fan motors are hooked to the fans with belts, similar to the belts you find in car engines. If the belt is damaged or comes loose, it will start rubbing against other components and make strange sounds. This needs repair as soon as possible before the belt can damage other parts of the AC’s interior.

All the problems above need professional attention in order to fix them properly and safely. Don’t pry open the air conditioner cabinet to inspect the problem yourself and fiddle with any mechanisms. Contact a technician to discover the source of the problem and to repair it.

Avoid getting stuck with a busted AC in Irvine, CA. Air conditioning repair is only a phone call away with Saddleback Plumbing.
