October 2024

Is your HVAC making a loud noise? It can be unsettling when you hear strange sounds coming from your system. You may wonder if it's just normal or something more serious. Below, we’ll discuss some of the most common HVAC noises and what they may mean. 

Common HVAC Noises and What They Mean

If your HVAC is making a loud noise, below we explore some of the most common occurrences and what you can do to fix or prevent them: 

• Screeching or squealing noises: These noises are often caused by a loose or worn belt. If you hear them, have your HVAC inspected by a professional as soon as possible.
• Rattling or clanking noises: These noises may be caused by a loose component, such as a ductwork connector. If you hear these noises, it’s important to have a technician service your HVAC system. 
• Whistling or hissing noises: These noises may be caused by a leak in your ductwork. If you hear whistling or hissing, a professional must inspect your system to locate and repair the leak.
• Banging or popping noises: These noises may be caused by a number of factors, including a loose ductwork connector, a clogged air filter, or a problem with the heat exchanger. Hearing these noises means it's time to call a professional to inspect and fix your HVAC system.
• Gurgling noises: These noises may be caused by a problem with your drain pan. If you hear something strange, it's essential to have a professional service your HVAC system. 

Tips on How to Prevent HVAC Noises

• Change your air filter regularly. A clogged air filter can restrict airflow and cause your HVAC system to work harder. This can lead to a variety of problems, including strange noises.
• Schedule regular HVAC maintenance. Regular HVAC preventative maintenance can help to prevent problems and keep your system running efficiently.
• Keep your outdoor unit clean. A dirty outdoor unit can restrict airflow and cause your HVAC system to work harder, leading to various problems, including weird sounds.
