A two-person shop where the owner writes the bid and is on the job. In December 2025 a customer wrote in to thank us for a furnace we installed in 2012 — still running, every winter since.
Residential and commercial work across San Francisco, specialising in high-efficiency systems.
High-efficiency gas furnaces sized for the house, installed to code.
Electric heat pumps for homes moving off gas — heating and cooling in one system.
Ducting designed and run with the system, so the back bedroom gets heat too.
Air conditioning installation and service for the days the fog does not show up.
Heater will not turn on? That is the call this shop takes all winter.
Commercial heating and air conditioning alongside the residential work.
Ocean Air Heating has been a family-owned San Francisco business since April 2008 — two people, an A+ rating on file with the Better Business Bureau, and California licence #968927. In their own words: “A family owned business, with over 20 years experience. We specialize in high efficiency heating and air conditioning systems.”
James Rector returns the call, writes the bid, and works on the job. That is the whole model, and it is why the reviews are full of people who came back, and people who wrote years after the work was finished.
“It's December 5, 2025 and we just turned on our furnace for the first time this year. I'm grateful every year at this time for the excellent work done by Ocean Air back in 2012.”
“Responsive, professional, helpful. James was easy to work with and gave me a competitive price.”
“We had a few issues with our heater during this cold winter. The heater wouldn't turn on. I called Ocean Air Heating and Steven came by to help. Steven was super friendly and very good…”
The shop is on 42nd Avenue out in the Sunset. The work goes wherever it is needed in the city:
