HVAC services in San Anselmo, CA
Heating and cooling for San Anselmo's bungalows, cottages and hillside homes in the heart of the Ross Valley.
Bungalows and cottages
Much of San Anselmo was built in the early and middle 1900s: craftsman bungalows near downtown, cottages on the hillsides and mid-century homes up in Sleepy Hollow. Many still have floor or wall furnaces, or forced-air systems added decades after the house was built, with ducts in a low crawl space.
When an older system starts to fail, we look at repairing it first, and explain clearly when a replacement would actually serve you better.
Hot days, cold nights
The Ross Valley warms up in summer and cools off quickly after dark, so San Anselmo homes need heat in the morning and, more and more, cooling in the afternoon. A heat pump handles both, and it is often the right move when an old furnace needs replacing.
Good to know
Should I replace my old floor furnace?
If it is decades old, hard to find parts for, or burns with a weak or yellow flame, have it looked at. Many owners replace a floor furnace with a modern forced-air system or a heat pump, and we will go through the options. If you ever smell gas, leave the house and call PG&E first.
How much does heating or AC repair cost in San Anselmo?
Costs vary by the issue and the system, which is why we give you a clear, upfront estimate before any work begins. No hidden fees or surprises.
Should I repair or replace my system?
If your system is over 15 years old and needs a major repair, replacing it often makes more sense. If it is younger, a repair usually does. We give you both prices and an honest opinion, and repair first whenever repair is the better value.
From our clients
“Bay Air Heating & Cooling did a wonderful job on the installation of our new HVAC system. They explained everything in detail and were very professional. Our garage was left spotless and the system has ran perfectly since they left.”

“They are professional and efficient. I've gotten estimates from other HVAC companies in the area, and Bay Air is by far better than the rest on both pricing and quality of work.”
Lynn S.
“The HVAC technicians have always been punctual, knowledgeable, and reasonable, and they've never tried to sell us services or repairs that weren't necessary. I really appreciate knowing things are done right every time!”
