Elkhart attics and basements often have accessible duct joints that were never sealed with mastic. Fix leaks before blaming the furnace for uneven rooms.
Typical homes can lose a large share of conditioned air through leaky joints. That shows up as uneven rooms, dusty basements, and higher furnace/AC runtimes — especially through Michiana winters.
Accessible basement/attic ducts can often be sealed with mastic and mesh. Ducts buried in finished walls usually need professional aerosol sealing or selective access.
DIY materials vs. professional sealing — typical Elkhart ranges

Assumptions behind these ranges
- Typical Elkhart / Elkhart County forced-air home (city median year built around 1965).
- No asbestos duct wrap assumed — older wraps need testing before disturbance.
- 2026 Midwest planning pricing — not an HVAC bid.
- Disconnected or crushed ducts may require repair beyond sealing.
What to ask about duct sealing in Elkhart
- Will you perform a duct leakage test before and after?
- Mastic on accessible joints, aerosol sealing, or both?
- Are disconnected or crushed sections included?
- Will you insulate ducts in unconditioned spaces?
- How do you handle possible asbestos wrap on older ducts?
