Possible Reasons Your Building’s HVAC Is Noisy

As a business owner or commercial property manager, having a quiet and efficient HVAC system is essential for the comfort of your building’s occupants. But when it starts to make unusual noises, it not only disrupts the work environment but could also signal underlying issues that require attention. In this blog, Schmitt Heating and Air Conditioning will outline potential causes of HVAC noises and provide solutions to ensure your system functions quietly and efficiently.

Identifying the Source of HVAC Noises

Upon hearing complaints about HVAC noise, it’s important to locate the source. Sounds originating from rooftop units might be more noticeable in top-floor offices. Rattling or clanging could point to loose components or improperly secured access doors. If your system emits pops or booms, especially from furnaces and boilers, you might be dealing with a potentially dangerous gas buildup and should seek the immediate expertise of an HVAC repair technician.

Aging and Wear

As your commercial HVAC equipment ages, its working parts can become worn or break, leading to an increase in noise levels. If your system is over 10 years old, it could be a sign that you need either targeted repairs or to consider replacing it. For younger units experiencing similar issues, specific parts may need repair or replacement.

Dirty Air Filters and Refrigerant Leaks

A clogged air filter can restrict airflow and cause the system to exert more effort, leading to lower efficiency and, of course, noise. Make sure to inspect it regularly to see if it needs cleaning or replacing. Additionally, hissing noises may denote refrigerant leaks, which, apart from increasing noise, can raise safety concerns and should be addressed promptly by a trusted AC repair technician.

Dealing With Ductwork and Fan Issues

Faulty ductwork can create a range of sounds, from hissing, which is indicative of air leaks, to humming or whistling noises. An imbalance in the fan blades can also cause unusual vibrations or noise. Regular maintenance can prevent these issues from escalating.

When To Call Professionals

Professional expertise is imperative, especially if the noise is too persistent or annoying to be ignored. Before something goes wrong that can cause the HVAC system to malfunction and compromise the comfort and well-being of your building’s occupants, make sure to stay on top of issues through regular maintenance and inspections. In doing so, you not only extend the life of your equipment but also ensure continuous business operations.
