Duct Sealing FAQs
What's the difference between duct cleaning and duct sealing?
Duct cleaning removes contaminants that are already inside your ductwork — dust, pollen, pet dander, and mold that accumulated over years of use. Duct sealing closes the gaps, cracks, and disconnected joints that let those contaminants get in and let conditioned air escape. Cleaning is a maintenance service; sealing is a repair that prevents the problem from recurring. Homes with unsealed ducts will re-contaminate quickly after cleaning because unfiltered air from the attic or crawl space keeps entering the system. For long-term indoor air quality improvement, both services are often needed — cleaning first, then sealing to keep it clean.
How much air do leaky ducts actually lose in Alabama homes?
The Department of Energy estimates that 20–30% of conditioned air is lost through leaks in a typical residential duct system, and Alabama homes often fall at the higher end. Two regional factors drive this: many Montgomery-area homes have ductwork running through unconditioned attics or crawl spaces (where temperature swings stress duct joints), and the region’s high humidity accelerates deterioration of older duct tape and seals. Homes built before 2000, homes that have had rodent activity in the attic, and homes with visible duct tape (as opposed to mastic sealant) at duct joints typically have the highest leak rates.
Can duct sealing help with my allergies?
Yes, and often more effectively than duct cleaning alone. Leaky return ducts pull unfiltered air directly from the attic or crawl space into your HVAC system — bringing pollen, dust, mold spores, and insulation fibers with it, bypassing your filter completely. During Alabama’s oak pollen season in March–May and ragweed season in September–October, this bypass can be the largest source of indoor allergens in your home. Sealing the return duct system forces all incoming air through your filter, which is where MERV 11+ filters can actually do their job. Homeowners with severe seasonal allergies often report the biggest improvement from duct sealing rather than from purifiers or filter upgrades alone.
How do I know if my ducts need sealing?
Common signs include rooms that are consistently harder to heat or cool than others, energy bills that are higher than similar homes in your neighborhood, dust returning quickly after cleaning, allergy symptoms worse indoors than outdoors, visible dust streaks around vent covers or duct joints, and musty or attic-like odors when the HVAC runs. Homes over 15 years old that have never had duct sealing performed are strong candidates regardless of symptoms, since duct tape and older mastic tend to fail on a 15–25 year cycle. A professional duct leakage test using a duct blaster is the only way to confirm and measure leaks precisely.
How much does duct sealing cost in Montgomery?
Duct sealing in Montgomery typically costs $500 to $1,500 for a single-family home, depending on the number of leak points, ductwork accessibility, and whether the system is in a conditioned space or requires attic/crawl space access. Manual sealing with mastic and mechanical fasteners is at the lower end of the range; aerosol-based sealing (Aeroseal-style methods) is at the higher end but reaches leaks manual sealing can’t access. Most homeowners recover the investment in 3–7 years through energy savings alone, and the improvement in comfort and air quality is typically immediate.
Is duct sealing better than replacing my ductwork?
For most homes, yes. Sealing costs a fraction of a full ductwork replacement (which runs $3,000–$10,000+) and addresses the same core problem — air loss and contamination — when the ducts themselves are structurally sound. Full replacement is usually only needed when ductwork is crushed, disconnected in multiple places, undersized for the HVAC system, or contaminated with mold beyond what cleaning and sealing can address. A professional inspection should evaluate whether sealing is viable before quoting a replacement; be cautious of any contractor that recommends full replacement without first testing for leaks and inspecting duct condition.
