Are you paying to heat the neighborhood? In many San Francisco, CA homes, nearly 30% of heated or cooled air never makes it to the living rooms. Instead, it leaks out through gaps, holes, and poor connections in the attic or crawlspace. We are your local energy efficiency experts. Our duct sealing services are designed to lower your utility bills, improve comfort, and extend the life of your HVAC equipment.

Leaky ducts create a pressure imbalance in your home. When supply ducts leak, you lose expensive conditioned air. When return ducts leak, they suck in dirty, unconditioned air from the attic—bringing in dust, insulation fibers, and humidity. This forces your system to run longer to reach the thermostat setting. By choosing to fix leaking ac ducts in attic, you essentially give your AC unit a vacation, allowing it to cool your home faster and with less effort.
We don't just slap duct tape on it (which, ironically, is terrible for sealing ducts). We use professional-grade mastic sealant and fiberglass mesh tape. This creates a permanent, airtight bond that will not dry out or peel off over time. We inspect every connection point—from the plenum to the boot—to ensure your system is airtight and efficient.

The most immediate benefit of duct sealing is comfort. Those "hot rooms" or drafty corners in your San Francisco, CA home are often caused by a lack of air pressure reaching the vent. Once we seal the leaks, the air pressure is restored, delivering strong, consistent airflow to every room in the house.
Every day you wait is money leaking out of your attic. Tighten up your home and lower your bills with professional duct sealing.

"My upstairs was always 10 degrees hotter than downstairs. The technician found a huge gap where the duct met the register. He sealed it, and now the temperature is balanced."
"I was skeptical that sealing holes would lower my bill, but my July bill was $40 lower than last year. The proof is in the savings."
"Very knowledgeable. He explained how negative pressure was pulling dust into my house. Since the sealing, the house stays clean much longer."
