Noisy air ducts can be annoying, but should they set the alarm bells ringing? Several reasons could be behind such sounds. Some are harmless while others are not so much. Today, Superior Air sheds light on the probable explanations for your loud ductwork.
There Is Excessive Static Pressure
Ask any experienced furnace and air conditioning maintenance professionals about duct noises, and they will most likely put the blame on high static pressure. This phenomenon means your HVAC system is struggling to move the air.
Apart from adjusting the fan speed, there is nothing you can personally do to quiet your HVAC system. The other feasible solutions to address high static pressure are installing a bypass duct, integrating more ductwork into the system, and replacing current grilles and registers with high-velocity versions.
Furthermore, the air will not move properly through the ductwork when some sections are sagging or bent. These structural issues can only be fixed by a timely furnace and air conditioning repair.
Your HVAC Infrastructure Is Not Optimal
When an air handler or a furnace is ducted to a wall opening with a grille on the opposite side or the central return, it can be difficult to render the airflow less audible. If this is the case, the HVAC system’s configuration should be changed.
You Installed New Equipment
If you suddenly hear popping noises coming from your ducts after a furnace or air conditioning installation project, your ductwork might not be compatible with your new system. The unpleasant sounds may also stem from fan or blower vibration. A delayed furnace ignition may be the cause of the racket too. Fortunately, all of these noise sources can be professionally troubleshot.
Do not take HVAC noises lightly, for they could be symptoms to more serious problems. Call Superior Air at (800) 462-0020 to request for service in Hanford, CA, and have a credentialed technician uncover what is behind the odd sounds.
