The Best Air Duct Sealing Services Longwood

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
