Duct Repair & Sealing in the Bay Area

Leaky ductwork can waste 20-30% of your heating and cooling energy, making your HVAC system work harder while delivering less comfort. Our duct repair and sealing services address these leaks, improving efficiency and comfort throughout your home. Common duct problems include disconnected sections, deteriorated joints, damaged flexible ducts, inadequate insulation, and poorly sealed connections. These issues allow conditioned air to escape into unconditioned spaces like attics, crawl spaces, and wall cavities. We use professional-grade sealing materials including mastic sealant and aerosol-based duct sealing technology (Aeroseal) that can seal leaks from the inside. For damaged sections, we repair or replace ductwork as needed. We also add or replace duct insulation to prevent energy loss. Signs you may need duct repair include uneven temperatures between rooms, rooms that are difficult to heat or cool, excessive dust around vents, high energy bills, or visible duct damage. Our duct testing can quantify exactly how much air your system is losing.
