Optimize Your HVAC System with Expert Ductwork and Insulation in Marin County and San Francisco
Our home’s ductwork and insulation are critical for maintaining energy efficiency, indoor air quality (IAQ), and comfort. Leaky ducts, clogged air passages, or poorly insulated attics and basements can waste energy, increase utility bills, and compromise air quality. At Bay Air Heating & Cooling, we offer comprehensive ductwork and insulation services to keep your home healthy and efficient.

Duct Repair, Replacement & Installation
Small issues in your ductwork, like leaks or loose connections, can lead to significant energy loss. Our services ensure consistent temperatures across your home, lower utility costs, and extended HVAC lifespan.

Duct Cleaning
Over time, dust, pet dander, mold spores, and allergens accumulate in your ducts, reducing airflow and polluting indoor air. That indoor air can be 3-5 times more contaminated than outdoor air, impacting allergies and respiratory health.

Attic Insulation
Uninsulated or under-insulated attics are a major source of energy loss, especially in unconditioned spaces. Proper attic insulation ensures consistent indoor temperatures, lower energy bills, and a reduced carbon footprint.

Basement Encapsulation
Basements and crawl spaces in Marin County and San Francisco are prone to moisture, mold, and energy loss. Encapsulation prevents water damage, discourages mold growth, and improves HVAC performance by keeping conditioned air stable.
