The person behind South Bay Air

Twenty-plus years in the trade, a San Jose company since 2015, and one owner who stays on your job from start to finish.

A small company, on purpose

Ross Stephan has over 20 years in the HVAC industry, with experience in residential and commercial work. South Bay Air started in 2015 and serves the Peninsula, South Bay and parts of the East Bay.

We stay small so the person who looks at your house is the person responsible for the result. That means fewer jobs at a time, and each one done properly: measured, permitted, tested and explained.

  1. Early 2000s

    Learning the trade

    Ross started in HVAC on residential service and commercial jobs around the Bay Area: service vans, rooftop units, tenant improvements and new construction.

    South Bay Air opens in San Jose

    After more than a decade working for others, Ross started his own company with a simple rule: size it right, install it cleanly, and answer the phone afterwards.

    Fire season changes the work

    Weeks of wildfire smoke made clean indoor air a real concern for Bay Area families. Filtration and fresh-air upgrades became a regular part of what we install.

  4. Today

    Peninsula, South Bay, East Bay

    We work in homes from Menlo Park to Morgan Hill and across into Fremont, on everything from a single mini-split to full heat-pump conversions and new custom homes.

Our mark is a floor plan of sorts: air finding its way through every room of a house.
