Signs You Need Duct Sealing

Leaks, poorly sealed joints, and lack of insulation can all lead to inefficiencies that reflect on your monthly utility bills. Duct leaks will also prevent your HVAC system from achieving or maintaining a desirable temperature, so your ductwork is a core component of your household comfort.

Signs you need duct sealing include:

  • Some rooms aren’t achieving the temperature on your thermostat setting.
  • You’ve noticed stuffy air or weak airflow.
  • Your energy bills have risen without explanation.
  • You see tangles, cracks, or bends in your flexible ducts.
  • Your indoor air quality is leading to sinus problems, headaches, and coughing.
  • You’ve noticed hot and cold spots in your home.
  • You have a mold infestation.
  • You’re experiencing increased dust buildup.

Duct sealing can eliminate all of those problems and more. Find out more by calling (510) 792-4328 or contacting AIS online.

Benefits of Air Duct Sealing

Did you know that faulty ductwork can contribute to up to 25% of the energy losses in your Bay Area home? It can also affect indoor air quality, distributing pollutants and contaminants throughout your home. Properly sealed ductwork saves you money and keeps you and your home comfortable.

Along with keeping your heating and cooling system operating efficiently, the benefits of air duct sealing include:

  • Improved energy efficiency
  • Prevention of backdrafting of fumes from gas appliances like furnaces, dryers, and water heaters into your ventilation system
  • Lower utility bills, thanks to temperatures being maintained at the right levels

If you’re ready to replace your old HVAC system, well-designed, well-sealed air ducts might also allow you to install a smaller and less costly HVAC system that’s better at dehumidification.

The Duct Sealing Process

The secret to a successful duct seal is a precise diagnosis. This is achieved by using a calibrated fan to place the duct system under pressure.

When we measure airflow, we can identify your total duct leakage as well as the location of individual leaks.

From there, we will pinpoint the amount of air you’re losing via common weak points like attics and garages. Duct sealing relies on construction-grade seals, mastic, and mesh to plug breaches.

The best way to ensure your ductwork is operating at peak performance is to have it inspected and assessed by a trained technician. AIS provides exceptional air duct sealing services that are guaranteed to improve your home’s comfort.

Don’t wait for small air duct issues to become big problems. Contact AIS online today or call us at (510) 792-4328.

Air Duct Sealing FAQs

How do I know if my air ducts need sealing?

If you notice one or more rooms has a higher or lower temperature than other rooms, you see water leaking from a duct, or you can see visible cracks and holes in your ductwork, it’s time to call in a professional technician to seal and repair the ducts as quickly as possible.

How long does duct sealing last?

Thanks to innovative fabrication techniques, duct sealing can last as long as the ducts themselves.

Traditional seals are designed to offer 30 years of sealing power. Flex duct sealants can achieve about half of that life span, but their durability relies on the quality of the seal and sealant.

Poorly chosen materials can fail within just three years, so it’s crucial to rely on a team that prides itself on quality ductwork services, starting with ductwork installation.

What does an air duct inspection accomplish?

One or more of our trained technicians will look for obvious leaks in your ductwork. We’ll calculate how much circulated air your home is actually losing in places like the garage, attic, or between walls. Many people are surprised to learn how much air they are losing through leaky ducts and vents.

Can sealed ductwork still be cleaned?

Yes, ducts can be successfully cleaned after being sealed.

What's the difference between duct sealing and duct repair?

Duct sealing is a form of duct repair, but the latter addresses a host of other problems. Torn or damaged ducts can’t always be repaired with a simple seal, so we might need to reconnect joints, repair S-locks, or place fiberglass duct boards.
Duct repairs can also address flawed or compromised designs. Ducts only function well with minimal turns and shortened pathways. If your ductwork was poorly designed, a repair could include a partial reinstallation. Repairs also address inadequate installation, which can lead to thermal loss.

How much does my ductwork affect my HVAC efficiency?

The Department of Energy has found that air leaks and gaps in your ducts can reduce your HVAC efficiency by as much as 40%. Forced air systems can only achieve adequate airflow if your duct walls and joints are completely free of cracks and holes.

Heat conduction is a lesser-known problem that allows thermal energy to pass into the metal walls of the duct, thereby undoing all the hard work your system has been doing.

In short, your ducts are the core of your climate control efficiency, so they need care and attention.

How much money can I save by sealing my ductwork?

Quite a lot! While exact savings are difficult to predict, government-sponsored studies show that sealing air ducts can save homeowners at least 20%; some save much more.
