DUCTWORK & INSULATION
Most homes in Austin lose 20–30% of conditioned air through leaky or undersized ductwork — you're paying to cool or heat your attic, not your living room. Northpoint's duct diagnostics use pressure testing and thermal imaging to find exactly where air is escaping, then seal, repair, or redesign the distribution system. The result is lower energy bills and rooms that finally hit their setpoint.
WHAT'S INCLUDED
- Duct leakage pressure testing (Duct Blaster)
- Mastic sealant and foil-tape duct sealing
- Flex duct replacement and rigid duct fabrication
- Zoning system design and installation
- Attic insulation audit and upgrade
- Air balancing — fix hot/cold room problems
Pricing
Duct diagnostic starting at $149. Sealing and repair quoted after assessment based on system size.
“Our back bedroom was always 6 degrees warmer than the thermostat. Northpoint ran the pressure test, found three disconnected flex ducts in the attic, sealed everything, and now the whole house is finally even.”
— James B.
COMMON QUESTIONS
How do I know if my ducts are leaking?
Rooms that never reach the thermostat setpoint, higher-than-expected energy bills, or visible disconnected flex duct in the attic are all signs. Our pressure test gives you a precise leakage percentage.
How much can duct sealing reduce my energy bill?
Homes with significant duct leakage typically see 15–25% reductions in cooling and heating costs after sealing. ROI is usually 2–4 years.
Do you handle attic insulation as well?
Yes — we partner with certified insulation contractors for attic blowback and air-sealing upgrades. We coordinate the whole job so the HVAC and building envelope work together.
