An efficiently running HVAC system is expected to operate quietly, providing comfort without noticeable background noise. However, if the HVAC system in your building starts producing an unusual sound, it could signify problems that can escalate if left unaddressed. Continue reading to learn about the common causes of a noisy commercial HVAC unit and ways to address the issue.
You might hear a low hum from your HVAC system as it operates, which is normal. However, unusual or louder-than-normal noises are not to be ignored. Top-floor offices or spaces directly beneath roof-mounted systems may be particularly prone to noisy disturbances from HVAC units. Whether it is a rattling, hissing, or clanking sound, identifying the source is crucial, and this often requires the expertise of a professional. Seeking out local HVAC services for such concerns is a step in the right direction.
Several components within your HVAC system can cause noise issues when they aren’t functioning correctly. Here are some of them.
Furnaces and Boilers
Loud pops or booming sounds coming from furnaces or boilers could indicate a dangerous buildup of gas, often due to unclean or blocked burners. Clicking noises may be attributed to a faulty igniter or flame sensor while rattling or clanging might suggest loose internal parts.
Air Conditioners and Heat Pumps
A screaming noise could point towards high pressure in the compressor, which should be addressed immediately. Bubbling or hissing noises often hint at a refrigerant leak, while squeals may indicate a need for lubrication of moving parts or belt replacement.
Faulty Ductwork
The ductwork can manifest various noises as well. Clicking or ticking can occur as the metal ducts expand and contract with temperature changes. However, persistent hissing or whistling may signify air leaks at joint connections or broken seals, which could to a loss of energy efficiency.
These strategies will help you prevent or address a noisy HVAC.
Seek Professional Help
Having a professional HVAC technician inspect your system is crucial. They have the expertise to identify the underlying issue and provide solutions to keep your unit in good working condition.
Regular Maintenance
Regular check-ups can prevent noise from becoming a persistent problem. Technicians address any minor issues before they escalate. They also ensure there are no refrigerant leaks that could affect your HVAC’s performance.
Soundproofing and Barriers
Encasing your HVAC units with sound-dampening materials or constructing barriers can help reduce noise transmission to indoor spaces.
HVAC Replacement
If the noises arise from an outdated system, it may be time to invest in a more modern, quieter HVAC system. This also allows you to benefit from the latest technology in heating and cooling.
