Signs Your Air Ducts Need Sealing

Problems We Help You Solve

Air duct sealing problems show up in different ways. If you notice any of these signs, leaking air ducts are likely costing you money and comfort.

Schedule Service

Excess Dust Throughout Your Home

When air ducts leak, dust from attics and crawl spaces gets pulled into your system and circulated through rooms. If you're constantly dusting or notice dust building up quickly, leaking ducts could be the cause. Air duct sealing keeps dust and debris out of your indoor air quality.

Hot or Cold Spots in Different Rooms

Some rooms won't cool down in summer or warm up in winter no matter what temperature you set. Leaks in your air ducts mean conditioned air never reaches those spaces. Duct sealing ensures every room gets proper airflow and maintains comfortable temperature.

Energy Bills Keep Climbing

If your heating and cooling bills are significantly higher than normal with no explanation, leaky ducts waste the air you're paying to condition. Air duct sealing service can reduce energy costs by stopping air leaks before they reach vents.

Increased Allergy or Respiratory Issues

Leaking air ducts allow dust, mold spores, and other contaminants to enter your ductwork and circulate through your house. If anyone in your home experiences more sneezing, coughing, or breathing problems, air leaks could be spreading irritants. Professional air duct sealing improves indoor air quality by keeping contaminants out.

Mold Growth in Unexpected Areas

Leaks in air ducts can spread moisture and allow mold to travel from one area to another. If you notice mold patches appearing around your Austin home, leaking ducts may be contributing. Our duct sealing service stops this moisture movement and helps protect your home.

Older Ductwork

If your duct system is 15+ years old and hasn't been sealed, leaks have likely developed at joints and connections over time. Even ducts that seem fine can lose 20-30% of airflow through small leaks. Duct sealing restores efficiency and helps your heating and cooling system work properly.

Frequently Asked Questions

How long does air duct sealant last?

Professional air duct sealing materials last 15-30 years when applied correctly. The sealant should last at least as long as your duct system itself. We use mastic sealant and metal-backed tape designed specifically for HVAC ductwork that withstands temperature changes in Austin attics.

Regular duct tape fails quickly in attic heat. Professional sealing materials remain flexible and maintain their seal through years of heating and cooling cycles. Proper maintenance of your HVAC system helps ensure the sealing service lasts as long as it should.

How does duct sealing work?

Our technicians access your ductwork in attics, crawl spaces, and walls to locate air leaks. We inspect joints, connections, and seams where ducts typically develop leaks over time. Using professional mastic sealant and metal-backed tape, we seal leaks at each location.

For larger gaps or damaged sections, we may recommend duct repair or replacement of that section. After sealing, we verify airflow improves and leakage stops. The sealing process focuses on stopping air leaks before conditioned air escapes into unconditioned spaces like attics.

Do air ducts need to be cleaned before air duct sealing?

It depends on your duct system's condition. Our professional HVAC technician assesses whether duct cleaning is necessary before sealing. In some cases, excessive dust and debris should be removed first. In others, sealing can proceed without cleaning.

If ducts have visible mold, significant dust buildup, or haven't been cleaned in many years, cleaning before sealing may be recommended. This ensures the sealing materials adhere properly and you're not trapping contaminants inside sealed ducts. We evaluate your specific situation and explain what makes sense before work begins.

Can air duct sealing help reduce my utility bills?

Yes. Air duct sealing significantly reduces energy costs by stopping conditioned air from escaping through leaks. When air ducts leak, your HVAC system runs longer to maintain temperature because much of the heated or cooled air never reaches rooms.

After professional air duct sealing, your system works more efficiently. Most Austin homeowners notice lower heating and cooling bills because less energy is wasted. The exact savings depend on how much leakage your ducts had, but reducing air leaks is one of the most cost-effective ways to improve efficiency.

How can I tell if I need my air ducts sealed?

Signs include hot or cold spots in different rooms, high energy bills with no explanation, excessive dust throughout your house, and uneven heating and cooling no matter what temperature you set. If some rooms never get comfortable or your system runs constantly, leaking air ducts are likely the cause.

Older ductwork also develops leaks over time at joints and connections. If your duct system is 15+ years old and hasn't been sealed, air leaks have probably developed. Our technicians can assess your ductwork and identify where air duct sealing service would help.

Can air duct sealing reduce the amount of dust in my home?

Yes. Air duct sealing can reduce dust significantly. Ductwork runs through dusty spaces like attics, walls, and crawl spaces. When air ducts leak, return air pulls dust and debris from these areas into your system and circulates it through your house.

Professional air duct sealing stops this infiltration. By sealing leaks, dust from attics and crawl spaces stays out of your indoor air quality. Many homeowners notice they don't need to dust as frequently after duct sealing service.

Does the sealant leave an odor?

No. Professional air duct sealing materials don't leave odors. The mastic sealant and metal-backed tape we use don't off-gas over time, so there's no lingering smell after application or during the life of the sealant. Your air ducts remain odor-free after sealing.
