Today’s air conditioners are as quiet as ever, which means that if yours is making a noise, chances are there is something wrong with it. Ignoring the noise isn’t going to do you any good; in most cases, it will just postpone the repair it needs. In some cases, waiting too long to call Total Care Heating and Air, your AC repair service in Riverside, will only increase the cost to fix the unit. This is because ignoring the mysterious noises from your air conditioner can turn minor issues into major expenses.

And just because your air conditioner is making a horrid noise not does mean it’s the end of the world, or of the life of your air conditioner. Heck, there is a chance that all it needs is a minor tune-up. Here are a few common sounds your air conditioner could be making and what it might signify.

Clanking

Clanking is a sound you hear when something is loose or out of balance in your air conditioner. Keep in mind that there are a lot of moving parts in your air conditioner and almost anything can go wrong that will cause this noise. For example, it could be a connecting rod, crankshaft or piston pin that broke or has come loose.

It could be something big, like the compressor. It might also be a blower that is no longer balanced.

Banging

Banging is another sound you will hear of there is a loose part. You might also have a fan blade that is loose and hitting other parts. It could be something rather minor, but could get worse if you ignore the problem.

Squealing

For some units, when the blower kicks on it is normal to hear a little squealing. But if the unit squeals all of the time, then there is a problem. Fan motors often start squealing when they are going bad. It’s something you need to have checked out right away.

Buzzing

The good news is that the buzzing you are hearing could be something really simple to fix, like an air filter that needs to be changed or a condenser coil that needs to be cleaned. But it could also be a fan motor that is about to fail or something more serious.

Humming

For the most part, humming noises usually aren’t very serious. But it does indicate that something is amiss and needs to be taken care of as soon as possible.

Buzzing can be caused by loose parts that are causing a vibration. It can also be caused by an electrical problem.

Clicking

You will hear a clicking noise when your unit is ready to shut down or start up. But if you hear a clicking noise all of the time, then something is just not right. Constant clicking can be caused by a defective control or a failing thermostat.

Chattering

Chattering, not to be confused with clanging and banging, can be caused by loose parts or perhaps twigs or leaves that have clogged the system.

If your air conditioner is making any of these noises, call Total Care Heating and Air right away!
