SERVING Deltona, FL
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.
Common Signs of Leaky Ducts:
- Excess Dust Buildup
- Dusty Vents & Registers
- Visible Insulation in Vents
- Uneven Room Temperatures
- Weak Airflow from Vents
- Rising Energy Bills
- A/C Running Constantly
- Inconsistent Indoor Comfort

Air Duct Sealing FAQs
Everything You Need to Know in Deltona
What is air duct sealing and how does it work?
Air duct sealing finds leaks, gaps, and disconnections in your HVAC ducts. Professionals then close these openings using materials like mastic sealant, aerosol sealant, or special tape. This stops air from escaping for better airflow at home.
How do I know if my ducts need sealing?
Common signs include:
- Uneven temperatures between rooms
- High energy bills
- Excessive dust or poor indoor air quality
- The HVAC system is running constantly
If you’re noticing these, your ducts may be leaking air.
Is air duct sealing worth it for homes in Deltona, FL?
Yes. Deltona’s hot, humid weather means your HVAC works hard most of the year. Sealing your ducts boosts efficiency, lowers your utility bills, and improves comfort—especially in older homes. The HVAC duct sealing cost in Deltona, FL, is often offset quickly by the energy savings it brings.
How long does professional duct sealing take?
Most projects take just a few hours or up to one day. This depends on your home’s size and ductwork condition. You’ll often notice better airflow and energy savings right away.
Will duct sealing really lower my energy bills?
That’s right. ENERGY STAR says sealing leaky ducts can save homeowners 20–30% on heating and cooling costs. Filterbuy has seen these savings in homes right here in Deltona.
