Key Signs You Need Air Duct Repair & Sealing
Unless you have access to exposed ductwork, it’s not always clear when ductwork is the issue causing an HVAC malfunction without a professional inspection. Signs you may need ductwork services include:
- Uneven heating or cooling
- Weak or no airflow
- Odd noises
- Higher than normal energy bills
- Dusty or musty air
- Visible damage to ducts
- Humidity or mold problems

Causes of Ductwork Deterioration
Your ducting plays a pivotal role in the operation of your heating and cooling systems. It needs to remain airtight to allow your treated air to reach all the spaces throughout your home without leaking. Because your ductwork is constantly circulating air throughout your home, poorly-maintained ducts can lead to indoor air quality problems.
Over time, the natural expansion and contraction of metal ducting can allow some of your joints to loosen up and create air leaks. These air leaks can allow unwanted dust and other debris to enter your ductwork while letting your treated air escape into your floors and walls. This will lead to decreased indoor comfort and poor indoor air quality. Our team can help identify issues and often restore your ducts to excellent condition with air duct repair and sealing.
When Should I Replace My Ductwork?
The lifespan of ductwork varies from 10 to 30 years. Metal ducts can last longer than fiberglass ducts. It’s likely time to replace your ductwork if:
- You’re replacing your heating and cooling systems
- Your ductwork is severely damaged.
- You’re remodeling your home and you need to extend ductwork to new rooms.

Air Duct Services FAQs
How Does Duct Sealing Work?
In areas where your ducting is exposed, we can use specialized foil tape to seal up any loose fittings or joints to make them airtight. We also offer professional duct sealing service to provide a permanent solution for the many air leaks in your ducting.
Our team will inject a specialized serum into your air ducts that will quickly harden. This creates an airtight seal over existing leaks in your system. When you get duct sealing service, you can rest assured that all the hot or cold air your HVAC system produces actually makes it to the various rooms in your home without leaking.
Can Dirty Air Ducts Affect My Allergies?
Dirty ductwork can have a significant impact on your allergies and the frequency of your flare-ups. As air circulates throughout your ducting, it can pick up unwanted airborne allergens and irritants and circulate them throughout your home. These include things like dust, pet dander, mold spores, pollen, and other pollutants.
