Leaky ducts can waste 20–30 % of the air your HVAC has already paid to heat or cool. Slide through the galleries below to see how Big Star Conservation turns energy-draining ductwork into a tightly sealed, high-efficiency delivery system—often at little or no cost to the homeowner.*





















What We Seal
- Plenum & Boot Connections – Mastic or UL-181 foil tape for a permanent seal
- Flex-to-Collar Joints – Secure straps plus mastic to stop spiraled leaks
- Accessible Mid-Runs – Aerosolized sealant for pinholes deep inside trunks
- Return-Side Gaps – Blocks attic dust, fiberglass, and pests from entering airflow
- Disconnected or Torn Runs – Re-hang, reconnect, and reinsulate where needed
All materials are code-approved, low-VOC, and rated for Louisiana attic temperatures.
Why Duct Sealing Pays Off
Result | Typical Improvement | What You’ll Notice |
Heating/Cooling Savings | 10 – 25 % annually | Lower bills next cycle |
Comfort | Even temps, faster system response | No more “never-comfortable” rooms |
Indoor Air Quality | Less attic/crawl-space dust pulled in | Cleaner vents, fewer allergies |
Humidity Control | Less moist outside air drawn through leaks | Reduced musty odors & mold risk |
HVAC Wear | Shorter runtimes, fewer starts | Longer equipment life, quieter |
Our 3-Step Path to Tighter Ducts
- Diagnostic Test – Duct-blaster fan quantifies leakage at 25 Pa.
- Targeted Sealing – Certified techs apply mastic, foil tape, and/or Aeroseal® aerosol.
- Verification & Rebates – We re-test to document leakage cut and file all utility paperwork.
Most homeowners invest $0–$250 out of pocket after incentives.
