Sounds Your AC Should Not Be Making

Air conditioning units, or ACs, are an important part of the indoor space. They contribute to indoor comfort during the summer. In return, they require that you keep them well-maintained. A well-maintained AC will run efficiently, save money, and keep your home cool.

When not well-maintained, your AC unit may start to give off signs. One of those important signs is strange noises. You should get AC repair services from Dayton Heating and Air, LLC if your AC unit is making unusual noises.

Below are some of the noises or sounds you should pay attention to.

Banging Noise

Your air conditioning unit should operate quietly and efficiently. This means that a noisy AC unit means there is a problem. However, banging noises from your AC unit can mean a big problem. Usually, this noise can be traced to loose or broken parts within the system.

Contact a professional if you can hear a banging noise from your air conditioning unit. Your AC repair technician can troubleshoot the problem and pinpoint the source.

Please be advised that you shouldn’t DIY this problem, especially as you could damage other parts of the AC unit. Doing this will cost you more money than repairing the original problem you tried DIY-ing.

Squealing Noise

Is your air conditioning unit squealing? The chances are high that there’s a problem with the belt. This problem is common with old and unmaintained ACs. Not to worry, it’s not expensive to fix. Contact your AC repair technician to look at the problem and diagnose it.

Now is also a good time to carry out AC maintenance services if you haven’t already done that. Your repair technician will check your AC system and point out other problems that require fixing to improve energy use efficiency and indoor comfort.

Humming Noise

Air conditioning units are expected to be quiet while working. However, they may give off low humming noise occasionally, especially if they are old or due for maintenance. If the low humming noise increases, then there’s a problem.

Loud humming noises from AC units are often indicative of capacitor or bad motor problems. In mild cases, the problem may be due to loose parts or electrical problems. You may also find that the problem may be from damaged refrigerant piping.

All of these problems should not be fixed using DIY methods. Instead, turn off the AC unit and contact your Ac repair technician. They will diagnose the problem and recommend appropriate fixes.

Clicking Or Rattling Noise

Loose parts and hardware are often the major cause of clicking or rattling noise within the AC unit. This problem can sometimes also be traced to a bad thermostat or electrical issues.

It is important to contact a professional for this problem. This is because electrical issues can sometimes be complex and dangerous to fix using DIY methods. You may also end up voiding your warranty and exposing yourself to more expensive repair costs.

A trained and experienced AC repair technician will diagnose the problem, determine the cause, and fix it as appropriate.

Slapping Noise

Slapping sounds similar to hitting the back of a person’s hand or playing a game of cards can be irritating. Nobody wants to hear such sounds while trying to relax on a hot summer afternoon. This sound may be due to loose parts which have found their way to the blower blades. It could also mean there’s an interference with the blower blades.

Turning off your AC unit when this sound comes on is important. Doing that will prevent the blower motor from overheating and going bad. Contact your AC repair technician as soon as you can. They can decouple the unit to investigate the problem and fix it.

Screaming Or Whistling Noise

This is perhaps one of the scariest noises you can expect from your AC unit. While it is quite unusual, it could happen. A screaming or whistling noise can be anything but good, so it’s best to shut off the unit as soon as the noise comes on.

The chances are high that this noise is due to a high internal pressure within the AC or a refrigerant leak. Depending on your AC unit’s model, it could automatically shut itself off for safety reasons. You should always contact a repair technician to investigate and fix this problem.

The above AC noises are less common when you have a solid maintenance plan in place. It is recommended that you contact a trusted AC repair provider to discuss your AC maintenance schedule to reduce repair costs and prolong your unit’s lifespan.
