A well-maintained HVAC system is one that you don’t notice at all. So when it starts making noise, it’s usually because of a problem — one that could disrupt your building’s operations if not fixed by your HVAC technician. In today’s post, Amber Air Conditioning Inc. takes a look at the reasons why commercial HVAC systems make noise.

Common Types of HVAC Noises

HVAC systems can make a variety of noises that can help you identify the problem:

• Explosive noises. Sudden pops and booms can indicate a dangerous condition, and usually happens in oil or gas-fired heating systems. Such noises are made by gas accumulating and igniting in an erratic manner, and are often due to clogged lines or a malfunctioning pilot light.
• Hissing or screaming noises. These sounds, similar to a kettle boiling, may suggest excessive pressure in an air pump’s compressor.
• Rattling and clanking. Such noises often point to improperly-closed panels or loose components. The former can be easily resolved — just locate the source and close the panels properly. The latter, on the other hand, may require an air conditioning repair professional because it could be anything from a loose bolt in the framing to a malfunctioning blower.
• Squeaking and squealing. HVAC systems have numerous moving parts that require lubrication. Motor belts can get worn out. Dust and dirt can get into the rotors. Squeaks and similar noises are indicative of wear. Continuing to use a worn-out HVAC system would only contribute to more wear, with a lower output.
• Hissing or whistling in the air ducts. Hissing noises in the air ducts indicate a leak, which could reduce the HVAC system’s heating and cooling output, as well as introduce contaminants to the indoor spaces.

What Should You Do?

Fortunately, the problems described above are preventable with regular maintenance. It’s important to note that scheduled appointments with an HVAC technician are but half of a proper maintenance routine. As the building manager or owner, you must include the HVAC systems as part of your monthly building maintenance routine. You’re not expected to perform repairs yourself, but keeping an eye — and an ear — out for signs of problems can help prevent business disruptions.

In the event that you notice such signs, or if a tenant reports such problems, try to isolate the source. Once identified, stop using the affected HVAC system in the meantime and schedule an appointment with your technician. Given that mechanical systems can only accumulate more wear through continued use, you can keep the repair costs down by addressing such problems sooner.
