Sound Levels by HVAC Component

Sound Levels by HVAC ComponentSince your HVAC system is comprised of mechanical equipment, it’s bound to make some noise when it’s running. The loudest sound levels are produced by the components that are located in your outdoor unit; the compressor and condenser. Indoors, you’ll likely hear the most noise from the blower fan as it cycles on, runs, and shuts off. Additionally, there may be a moderate amount of noise made as air moves through the ductwork. Your HVAC system can produce more or less noise due to other reasons too:

  • If you have higher-quality equipment that build more durably, it will likely make less noise.
  • As your HVAC components age or develop performance issues, you can expect them to produce more noise.
  • If you have larger, higher-capacity equipment, it will likely sound louder than most smaller units.
  • If your equipment wasn’t installed with care, you might hear noises like rattling from an off-level compressor or air handler, or creaks/pings/pops from improperly-secured ducting.

If you have concerns about newly-developed or excessive noise in your HVAC system, a trusted HVAC pro can check if there’s a repair needed, or if there are solutions available to reduce the sound levels.

How to Choose New Components With Lower Sound Levels

HVAC components sound levels are measured in decibels (db), and quiet equipment has a lower db value. A knowledgeable HVAC pro can help you compare the db ratings for different equipment brands and models, and give you advice on features to look for, like:

  • Variable-speed blower. These units provide ultra-quiet efficient operation because they’re designed to run on the lowest effective fan speed.
  • Noise-reducing outdoor cabinet. Quiet outdoor units have better insulation, anti-vibration mounts, and grills that reduce noisy airflow.
  • Direct-drive condenser fan. A well-balanced direct-drive fan also helps limit noisy outdoor unit operation.
  • Discharge muffler. A muffler on the compressor’s discharge lines helps smooth out sounds caused by pulsations and vibrations.
