Why Is My Air Conditioner So Loud?

With the scorching summers in the Dallas area, your air conditioner needs to work hard to keep your home cool. Even with the hard work, though, your AC unit should be fairly quiet. Some noises from your unit are certainly expected, but if your AC is getting so loud that it’s starting to annoy you, then something is wrong. If the noise from your AC becomes louder or changes, then you need to have your system inspected. In this blog, our air conditioning experts at Total Air will cover the different types of loud noises your system may face, their common causes, and how to fix them.

My AC Is Louder Than Normal

Between service visits, an air conditioner can collect dust, dirt, and debris. As this builds up, your air conditioner will have to work harder to ensure your home has sufficient cooling and airflow. This alone will cause your AC to be louder than normal, but the debris can also interfere with the heat transfer process, increasing the workload on the system. This all adds up to your AC having to work overtime, which means it will be louder.

Staying current with the routine maintenance of your air conditioner will prevent many of these problems. Plus, regular maintenance also helps to keep your energy costs to a minimum and increases the service life of your system. Be sure to schedule air conditioner maintenance at least once a year, and consider signing up for a preventative maintenance plan to make the process simple and cost-effective.

If you have an older AC system that has always been loud, upgrading to a variable-speed blower may be an option to quiet it down, as well as a complete AC replacement. If your air conditioner is over 15 years old, installing a new system can offer quieter operation, significantly improved comfort, lower energy costs, and other great benefits.

My AC Is Making New or Different Noises

Noises that are new, have changed, or are significantly louder may be an indication of a major problem with your air conditioner, such as a failing compressor, bad blower motor bearings, or mechanical damage. Call an AC repair service if you notice any of the following sounds:

• Humming or buzzing: If the sound is coming from the interior portion of your air conditioner, it may indicate an electrical problem or a blower motor that has failed to start. Similar sounds from the outside may point to a compressor failure, a condenser fan failure, a damaged relay, or a faulty capacitor.
• Screaming or screeching: A loose belt on a blower fan could cause screeching, but it may also be damaged bearings in a blower motor or a failing compressor.
• Clicking or tapping: Occasional or frequent clicking may indicate a faulty relay or contactor, while constant clicking or tapping may be caused by a damaged belt or debris caught in a fan.
• Rattling or clanking: Loose access covers can often cause abnormal noises, but rattling or clanking can also be caused by loose or misaligned parts like fans, as well as debris caught in moving components.

Taking swift action to diagnose unusual AC sounds can often save money on repairs while protecting your system from damage.
