Up to 30 % of the air your HVAC system conditions never reaches the rooms you live in—it escapes through holes, tears, or loose seams in your ductwork. Big Star Conservation’s professional duct sealing service tracks down those leaks and seals them tight, delivering more comfort for less money. Most Louisiana homeowners qualify for generous utility incentives that cover all or most of the job.
Why Invest in Duct Sealing?
Benefit | What It Means for You |
Lower Energy Bills | Pay to heat or cool your rooms—not your crawl space or attic. |
Greater Comfort | Even temperatures, faster warm-ups/cool-downs, fewer hot or cold spots. |
Healthier Air Quality | Keep dust, insulation fibers, and pests from being sucked into supply ducts. |
HVAC Longevity | Reduced runtime lowers wear on compressors, blowers, and heat exchangers. |
Proven ROI | Typical payback is 12–24 months when incentives are applied. |

Frequently Asked Questions
Is this the same as “cleaning” my ducts?
No. Cleaning removes dust from inside the ducts; sealing closes holes, joints, and tears so conditioned air can’t leak out (or contaminants leak in).
Will you need to cut into my ceilings or walls?
Rarely. Most repairs occur at accessible joints near the air handler, plenums, or visible runs in the attic/crawl space.
How long until I see savings?
Most clients notice lower energy bills the very next billing cycle, with full payback in one to two years—even faster with utility incentives.
Does duct sealing void my HVAC warranty?
No. Using approved mastics or aerosol sealants is recommended by manufacturers and often required for new-construction code compliance.
Can you seal ducts in mobile or manufactured homes?
Yes—we routinely work on flex and metal trunk-line systems in manufactured housing.
