What’s That Sound? Identifying Common Ductwork Noises

Unexpected ductwork sounds can disrupt your home’s peace. These noises are your HVAC system’s way of communicating that something needs attention. Each sound tells a different story, and understanding them is the first step to restoring quiet in your Grants Pass home. Let’s explore the most common duct sounds and what they mean.

Banging, Popping, and Clanging

Sudden bangs from vents are a common complaint in Southern Oregon. The usual culprit is metal ductwork expanding and contracting with temperature changes. Like a baking sheet in an oven, your ducts expand with hot air and contract as they cool, creating loud banging or popping sounds.

Air pressure also plays a role. If your system pushes air too forcefully, the pressure can cause ducts to flex and bang. This is common if your ducts are undersized for the HVAC system, especially after a furnace upgrade without new ductwork.

Sometimes the bang comes from the furnace itself. Dirty burners can cause delayed ignition—a dangerous gas buildup that ignites with a loud boom. This requires immediate professional attention.

Our article on dealing with a noisy furnace provides more detailed information if you suspect your furnace is the source.

Whistling, Hissing, and Humming

Steady whistling or hissing usually points to airflow problems that often waste energy and money.

A clogged air filter is a top cause of whistling. As the filter fills with debris, the system works harder to force air through, creating a whining sound.

Blocked vents create similar issues. If furniture or curtains cover a vent, air can’t flow freely, creating pressure imbalances that cause whistling or hissing.

Constant hissing may indicate air leaks in your ductwork from loose connections or holes. This noise means conditioned air is escaping, wasting energy and reducing comfort. Our guide on how to tell if you have an air duct leak can help you identify this issue.

Blower fan issues, like a loose belt or unbalanced blade, can also create persistent humming or whining noises that travel through your ducts.

Rattling, Rumbling, and Scratching

These sounds suggest something is loose or moving inside your ducts, from annoying rattles to unsettling scratching.

Loose parts like screws, brackets, or dampers often cause rattling. System vibrations can loosen them over time, causing them to vibrate against the ductwork.

Debris in ducts—like dust, insulation, or construction materials—can also cause rattling or rumbling as air flows past. This is a clear sign that duct cleaning making noise in grants pass or is needed.

Scratching sounds are the most concerning, often indicating pests or animals in your ductwork. This poses serious health and air quality risks.

A failing motor in your furnace or air handler can also cause rattling or rumbling as its vibrations travel through the connected ductwork.

How to Silence Your Ducts: DIY Fixes and Professional Solutions

Once you’ve identified the cause of the noise, it’s time to fix it. Some issues are simple DIY fixes, while others require professional help. Safety first: Always turn off your HVAC system completely at the thermostat and circuit breaker before any inspection or repair. Ducts have sharp edges, and moving parts can cause injury.

DIY troubleshooting can save you money, but knowing when to call an expert is just as important. Regular professional inspections catch problems before they become expensive. Our article on the importance of having ductwork inspected by HVAC pros explains why trained eyes make a difference.

Simple DIY Checks and Fixes

Start with these simple checks that often solve noisy duct problems.

Check your air filters first. This is the easiest and most effective fix. If you can’t see light through your filter, replace it. In Southern Oregon, check filters monthly and replace them every 90 days—more often if you have pets, allergies, or after construction. A clean filter improves airflow and reduces noise.

Walk through your home and inspect every vent cover. Ensure no furniture or rugs are blocking your supply or return vents. Wipe down the grilles and check that nothing has fallen inside.

If you can access your ductwork in a basement, attic, or crawl space, use a flashlight to inspect for loose connections. Tighten any loose screws or brackets. You can seal small gaps at joints with specialized duct mastic and mesh tape to stop hissing from air leaks.

Check for visible blockages by removing a vent grille with the system off. Use a flashlight to look inside. You can remove debris near the opening with a vacuum attachment, but leave deeper blockages for a professional to avoid causing damage.

These maintenance steps can improve your home’s air quality and comfort. For more tips, see our guide on useful tips for keeping the air in your home clean & flowing smoothly.

Frequently Asked Questions about Noisy Ducts

Many homeowners are puzzled by noises from their vents. Here are answers to common questions about noisy ductwork.

How often should air ducts be cleaned?

Generally, ducts should be professionally cleaned every 3 to 5 years. However, several factors might require more frequent cleaning.

  • If you have pets that shed, consider cleaning every 1-2 years.
  • For households with allergies or asthma, cleaning every 2-3 years can significantly reduce airborne irritants.
  • Smokers in the home warrant more frequent cleaning due to residue buildup.
  • Schedule a cleaning after any construction or renovation to remove dust and debris.
  • Immediate cleaning is necessary for water damage or suspected mold.
  • It’s also wise to clean the ducts after moving into a new home, especially an older one, to ensure a fresh start.

For a more detailed breakdown, check out our guide on how often should you have your air ducts cleaned?

Can a dirty furnace cause ductwork to make noise?

Yes. The furnace and ductwork are connected, so a problem in one can cause noise in the other. A clogged furnace filter is a common cause. It restricts airflow, forcing the blower motor to strain, which creates whistling or humming. The resulting pressure imbalances can also cause banging or popping sounds in the ducts.

Restricted airflow can also cause the furnace to overheat. Safety mechanisms may shut the system down, causing components to expand and contract rapidly, which creates loud banging sounds.

The most concerning noise is a loud bang from delayed ignition. This occurs when dirty burners let gas build up before igniting. It’s a safety hazard requiring immediate professional service. If your furnace seems to be acting up, our article on why is there a blinking red light on my furnace? might help you troubleshoot.

Are leaking ducts noisy?

Yes, and they also waste money and reduce comfort. Leaking ducts often create a whistling or hissing sound as conditioned air escapes through cracks or holes. The noise is just a symptom; the real problem is air escaping into your attic, crawl space, or walls.

This forces your HVAC system to work harder, increasing energy bills. Leaks can also pull in dust and contaminants, degrading air quality and causing uneven temperatures throughout your home.

If you suspect you have duct leaks, our article on how to tell if you have an air duct leak can help. We also explain why ductwork leaks are bad for indoor air quality in another guide. When it comes to duct cleaning making noise in grants pass or addressing leaks, professional sealing is the most effective solution.
