Most homes on the Tiburon peninsula need heat far more often than cooling. The bay keeps summers mild, wind and fog cool the evenings, and the few warm afternoons land hardest on rooms with large west-facing windows. In Mill Valley, homes on shaded lots under the redwoods stay cool and damp for much of the year. So the work we do most is keeping heat steady and quiet, protecting outdoor equipment from salt air and moisture, and fitting efficient systems into houses that were never built for them.
Tiburon HVAC has worked in Tiburon, Belvedere and Mill Valley since 2002, from our office at 1690 Tiburon Blvd. Every visit starts with a diagnosis, and you get the price before any work begins.
What we work on
- Heating. Heating repair covers furnaces, boilers, heat pumps and radiant systems. Furnace repair handles no-heat calls on gas furnaces, and furnace installation replaces a unit at the end of its life.
- Heat pumps. Heat pump installation often replaces an old furnace and air conditioner with one system that does both. Heat pump repair covers defrost, sensor and inverter faults.
- Ductless mini-splits. Mini-split installation suits view rooms, additions and older homes with no space for ducts. Mini-split repair starts with the error code on the indoor unit.
- Cooling. AC repair, AC installation and a spring AC tune-up for systems that sit idle most of the year.
- Air and ducts. Duct cleaning and indoor air quality work for dust, damp and musty air.
- Upkeep and urgent calls. Yearly HVAC maintenance, and 24/7 emergency HVAC for no heat on a cold night or a system that trips the breaker.
What homes here ask of a system
Salt air. Near the water, salt and moisture corrode outdoor coil fins, cabinet screws and electrical connections faster than they would inland. Rinsing the outdoor coil and checking the connections once a year slows the damage.
Large houses with several zones. Hillside and waterfront homes often have more than one system, long duct runs and, in some, radiant floors. When one wing never gets comfortable, the cause is usually a zone damper, a thermostat or a long duct run, not a weak furnace.
Older homes with little room. Cottages on the peninsula and Mill Valley houses from the early 1900s to the 1960s often have ducts in a crawlspace and no spare space for larger equipment. That is why heat pumps and ductless mini-splits are such common upgrades here.
Neighbors close by. Outdoor units often sit near a property line, a deck or a bedroom window, and neighbors and HOAs care about noise and placement. When we install, we plan the location with you and favor quiet, variable-speed equipment.
