Damaged or leaking ducts can send conditioned air into attics, crawl spaces, and other areas where it does your home no good. Brennan Heating, Air Conditioning, Plumbing, and Electrical provides duct repair for Seattle homeowners experiencing weak airflow, uneven room temperatures, or unexplained energy use.

Call (425) 610-9839 to schedule a ductwork evaluation and discuss the right repair or sealing option for your home.

Testing Reveals Visible & Concealed Duct Leaks

A useful assessment goes beyond checking the vents in each room. Technicians can inspect accessible ducts while the heating and cooling system operates, looking for gaps, tears, loose connections, and disconnected sections.

Not every leak is visible. Ducts often pass behind walls, beneath floors, and above ceilings, so pressure testing may be needed to evaluate concealed sections. A digital manometer measures air-pressure differences and helps identify leakage that a visual inspection can’t reveal.

When Repair Is Appropriate
Repair can restore damaged seams, failed connections, and isolated sections when the overall network remains structurally serviceable. The required work depends on the location and accessibility of the damage and whether individual sections can be restored without extensive replacement.

When Replacement May Be Appropriate
Replacement may be considered when deterioration or damage affects large portions of the ductwork. We assess the condition and extent of the problem before work begins, so you understand why we recommend repair, sealing, or replacement.

Aeroseal Sealing Delivers Measured Leakage Results

Small leaks can be difficult to reach from the outside, especially when ductwork runs through enclosed spaces. We offer Aeroseal duct sealing, which pressurizes the ducts and releases aerosolized polymers inside them. The material collects at cracks and crevices to seal leaks from within.

We test for duct leakage before and after every sealing job, providing a measurable comparison rather than relying on visual assessment alone. You’ll also receive a Certificate of Completion that quantifies the results.

Qualifying homeowners who complete this service through us can earn rebates of up to $1,250. Eligibility determines the available rebate, and we can explain the applicable requirements during your consultation.
