The Best in Air Duct Sealing

Air ducts are often hidden in hard-to-reach areas, making it easy to overlook leaks that allow cool air (and your money!) to escape. Filterbuy HVAC Solutions use proprietary Aeroseal technology to seal these gaps to ensure your system runs efficiently and leak-free.

Using a non-toxic, industry-leading sealant, we seal ducts from the inside to prevent energy loss. Just like a leaky faucet, unsealed ducts can waste hundreds or even thousands of dollars over time. If you suspect leaks, don’t wait—sealing your ducts could cut your energy bill by up to 50%.

Signs Your Air Ducts Need Sealing

Leaky air ducts can reduce your home’s comfort, drive up energy costs, and overwork your HVAC system. If you notice excess dust even with clean filters, it could mean air is escaping through gaps in your ductwork.

One of the most expensive consequences of leaky ducts is higher energy bills. When cooled air escapes into your attic or other unconditioned spaces, your HVAC system works harder to compensate, wasting energy and increasing costs. Sealing your ducts helps restore efficiency, reduce expenses, and improve overall indoor comfort.

Air Duct Sealing FAQs

Everything You Need to Know in DeLand

What is air duct sealing and why does it matter?

Air duct sealing means finding and closing leaks or gaps in your home’s ductwork. These leaks let air escape. That causes weak airflow, uneven room temperatures and higher energy bills. Sealing the leaks helps your HVAC work better. It also keeps your home more comfortable all year long.

Common signs are rooms that are hard to heat or cool. Also, high energy bills, dusty air inside or your HVAC turning on and off often. A professional checkup in your DeLand home can show if your ducts are leaking and how much air is being lost.

 

ENERGY STAR says sealing ducts can cut energy bills by up to 20%. In many DeLand homes we’ve worked on, savings are often between 15% and 30%, depending on how leaky the ducts were. The HVAC duct sealing cost in DeLand, FL is a smart investment that pays off in energy savings.

Will duct sealing improve indoor air quality?

Yes. Leaky ducts pull in dust, allergens, and dirty air from crawl spaces, attics, and garages. Sealing the ducts helps block these pollutants. This makes your indoor air cleaner and safer—especially for families with allergies or asthma.

Most homes in DeLand can be inspected and sealed in one visit. This usually takes 2 to 5 hours. The process doesn’t require major work and you’ll notice better comfort and system performance right away.
