Why Is My AC Making a Loud Noise and How To Fix It?

Hearing a slight hum or minor HVAC system noise isn’t a cause for concern — provided it doesn’t get too noticeable. It’s smart to schedule AC repair services in Keller, TX if you find yourself wondering, “Why is my AC making a loud noise?” The qualified technicians at Minuteman Heating & Air reveal the common culprits behind unusual air conditioning sounds. 

Why Air Conditioners in Keller, TX, Make Strange Noises

You might hear a wide array of sounds coming from your air conditioner, including grinding, rattling, or banging noises. Experts can pinpoint the source of the problem based on the sound, but the following are some of the most common issues they encounter when fixing faulty units in Keller. 

Debris in Your Unit

Why is my AC making a loud noise that sounds like objects rattling together? As the unit tries to cool your home, the fan blades could also be hitting foreign objects inside your condenser unit, such as:

  • Leaves
  • Twigs
  • Plastic items

Catching the problem quickly minimizes damage to your unit, particularly the fan blades. Try to keep the space around your outdoor unit clear so debris doesn’t infiltrate the system and affect the cooling process. 

Loose or Broken Parts

Hearing loud compressor sounds could be due to loose internal components. Your cooling system consists of different bolts and screws that hold panels together for seamless operation. This equipment can suddenly become loose and produce a strong vibration within your unit. 

If one of the pieces falls out and keeps hitting the fan blades, you’ll likely hear a loud banging noise. Shut off your system and have an expert inspect your unit immediately to prevent further damage to your fan, compressor, or other essential parts. 

Refrigerant Leaks

Loose screws aren’t the only cause of AC unit vibration issues. Buzzing noises often accompany refrigerant leaks. When your unit starts leaking refrigerant, it will not only produce a loud buzzing noise but also impact how well your system cools your home. 

Having enough refrigerant inside your air conditioning coils ensures that the system can trap heat from inside your house and replace it with cool, comfortable air. As refrigerant leaks, it becomes harder for the unit to cool the space, which may lead to increases in your energy costs. Don’t hesitate to call for repairs at the first sign of a leak since exposure to this hazardous material can have significant health risks. 

How To Prevent Common Air Conditioning Problems

The last thing any Keller homeowner wants to deal with is an expected air conditioner malfunction, especially during the scorching summer months. You can try to stay cool without using your air conditioner, but taking steps to preserve your system will help you in the long run. Check out tips for getting the most out of your unit. 

Replace Your Air Filter

Aside from, “Why is my AC making a loud noise?” a common question technicians hear from homeowners is, “Why won’t my air conditioner blow cool air?” Clogged air filters restrict airflow and can lead to other mechanical problems if you don’t address them quickly. Experts recommend replacing your filter every three months, though you might need to change yours more frequently depending on factors like:

  • The number of people in your house
  • Whether you have pets 
  • If anyone in the house smokes 

All of these factors can cause a faster buildup of dirt and allergens in an HVAC air filter. 

Invest in Routine Maintenance

The best way to keep your air conditioner working properly is to invest in professional maintenance. Changing the air filter is a simple, DIY way to prevent airflow problems, but for the best results, schedule a yearly tune-up service with your local HVAC contractor. 

Experts will take care of common issues affecting cooling systems, such as dirty coils and low refrigerant levels. Prioritizing maintenance helps your system run more efficiently and extends its lifespan.
