A noisy HVAC system can be more than just an annoyance; it could also be a sign that something is amiss. The good news is that most HVAC noise issues can be resolved with a bit of troubleshooting and maintenance.
At Zark Heating & Cooling, we’ve put together some practical tips to help you quiet your system and restore peace to your home.
The first step to resolving HVAC noise issues is to pinpoint where the noise is coming from. Is it the indoor unit, outdoor unit, or ductwork? Different noises often indicate different problems:
Banging or Clanking: This could mean a loose or broken part inside the system.
Whistling: Often caused by air leaks in the ductwork or a clogged air filter.
Rattling: May indicate loose panels or screws.
Humming: Could be related to electrical components, such as the motor or capacitor.
Once you identify the source, you’ll have a clearer idea of what needs to be addressed.
Check and Replace the Air Filter
One of the simplest ways to reduce HVAC noise is to ensure that your air filter is clean. A dirty or clogged filter restricts airflow, forcing the system to work harder and potentially creating noise. Replace the filter every 1-3 months, depending on usage and the type of filter you use.
Tighten Loose Parts
Over time, vibrations from your HVAC system can cause screws, bolts, and other components to loosen. Inspect the unit and use a screwdriver or wrench to tighten any loose parts. Pay special attention to the panels and brackets.
Insulate Your Ductwork
If the noise is coming from your ductwork, adding insulation can help dampen the sound. Foam insulation or duct liners can be installed to reduce vibrations and the noise of air moving through the ducts. Additionally, check for and seal any leaks in the ductwork with metal tape or mastic sealant.
Install a Sound Blanket
For noisy outdoor units, a sound blanket can be an effective solution. These specially designed covers reduce the noise of the compressor without impacting the unit’s performance. Many HVAC manufacturers offer sound blankets as an accessory.
Level the Unit
A tilted or uneven outdoor HVAC unit can cause additional vibrations and noise. Use a level to check if the unit is sitting properly, and adjust it as needed. You may need to add or remove soil or use rubber pads to stabilize the unit.
Schedule Professional Maintenance
Regular maintenance is essential for keeping your HVAC system running quietly and efficiently. A professional technician can:
Inspect and clean the system thoroughly.
Lubricate moving parts.
Replace worn-out components.
Diagnose and fix underlying issues.

When to Call a Professional
