Hidden duct leaks can send heating and cooling into the wrong spaces. We test your system, address the leaks, and document the change—with one in-house team from start to finish.
Compare airflow before and after duct sealing with Project Probono.
Supply leaks can waste conditioned air before it reaches your rooms. Return leaks can draw air from attics, crawlspaces, or other unintended spaces into the system.
Sealing those pathways can improve air delivery, comfort, and efficiency. The benefit depends on where the leaks are, how much air escapes, and the condition of the system.
Explore our diagnostic testing →We inspect accessible ductwork and measure leakage to identify the starting condition and the right scope of work.
We prepare the system, address repairs where needed, and use Aeroseal technology to seal duct leakage from the inside while monitoring progress.
Your before-and-after leakage results show the measured reduction. We review the outcome and explain any remaining recommendations.
Duct cleaning removes accumulated debris. Duct sealing closes air-leakage pathways. When both are appropriate, we plan them together and clean before sealing.
Discuss your duct systemDuct sealing does not replace necessary duct repairs, equipment service, or moisture-source correction. We explain those needs when the assessment identifies them.
