Odd Noises You Might Hear When Your Air Conditioner Needs To Be Repaired

Even if your air conditioner seems to be cooling your house okay, it could still be in need of repairs. One way to tell something is wrong with your AC is when it starts making new or odd noises. If your AC is making a noise you can't identify and fix, then call an air conditioner repair service to get to the bottom of the issue before damage is done to your AC system. Here are some noises you might hear and what they could mean.

Clicking Noises

You're used to hearing clicking noises when the thermostat triggers your AC to turn on. If something goes wrong with your thermostat, you may hear those clicking noises more frequently. In addition to the clicking, it may seem like your AC is cycling on and off more frequently. If your thermostat has problems, you want to get them fixed promptly or your AC may turn on and off erratically and drive up your power bill.

Loud Screeching

You've probably heard the screeching sounds a failing motor can make, and you'll hear a similar sound coming from your AC when a motor goes bad. The sound can even be amplified by the ducts. When your AC emits a loud screeching or squealing noise, kill the power to the AC and call a repair service to take a look. Loud screeching is a sign of failure of some part of your system, and running the air conditioner under those conditions could cause expensive damage or could even be dangerous.

Clattering Noises

Your air conditioner has moving parts in it that can get out of alignment and rub or bang against each other. This can happen in the indoor air handler since the blower fan is in constant motion when the AC is on. It can also happen in the outdoor unit if the slab sinks or the unit tilts a little. Clattering can also be caused in the indoor unit if a screw gets loose and bangs around or in the outdoor unit if a twig or other debris gets caught and bangs against the metal parts. Since this sound indicates that parts are hitting each other, you'll want an air conditioning repair company to find the problem and fix it before the parts get damaged and are more costly to repair.

Regular air conditioning services can sometimes prevent problems like these, but even if you have regular maintenance, things can go wrong with your AC, especially when it gets older. Use these unusual sounds as a guide that lets you know it's time to call for repairs. Contact air conditioning services for more information.
