HVAC Company in San Anselmo, CA
Meadowsweet Heating & Air is the HVAC company San Anselmo homeowners call when a home built in 1927 needs modern cooling without tearing out plaster walls, or when a furnace in a creek-side crawlspace quits on a damp January night. San Anselmo jobs run different from the rest of Marin because the housing stock is old, the valley heat is real, and the flood history along San Anselmo Creek keeps showing up inside equipment years later. We handle AC repair, furnace repair, and AC installation for homes throughout San Anselmo, with a written price before any work starts and a live person on the phone at (747) 966-3037 whenever you call.
Why San Anselmo Homes Are Different
San Anselmo sits in the Ross Valley, where the marine layer burns off by mid-morning and the valley traps radiated heat. Summer afternoons regularly push into the mid-to-upper 80s°F, sometimes past 90°F during heat events, which is 15-20°F warmer than bayside towns like Larkspur or Kentfield. That heat lands hard on houses that were never built for it. Most of San Anselmo’s residential stock dates from roughly 1900 to 1950: Craftsman bungalows, Colonial Revivals, and early ranch homes with pier-and-beam foundations and balloon-framed walls. There’s no plenum space for conventional ductwork in most of them, which is why ductless mini-split systems have become the default cooling upgrade here. Winter brings a different problem: persistent valley fog and damp nights that create real heating loads in wood-frame walls that often lack insulation. Add San Anselmo Creek’s flood history, most severely in 2005 and 2006, and we routinely open furnaces or air handlers in lower-lying neighborhoods near Sir Francis Drake Boulevard that show the rust, mud, and gas-valve corrosion left behind by water years ago. In San Anselmo, the house itself tells you what the system needs before you even take the panel off.
Our Main San Anselmo Services
Most San Anselmo calls come down to two things: heat that won’t cool and a furnace that won’t fire. Each service has its own dedicated San Anselmo page with full pricing and local detail.
AC Repair in San Anselmo
When the valley heat settles in and a mini-split or a window unit can’t keep up, our technicians start by checking the outdoor unit’s airflow, the refrigerant charge, and the condensate path, all of which take extra strain during those 90°F afternoons. We service ductless mini-split systems along with Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. Written pricing comes before any repair begins. AC Repair in San Anselmo

Furnace Repair in San Anselmo
Furnaces in San Anselmo’s older homes often sit in open crawlspaces, where damp winter air and past flooding along the creek corridor take a toll on heat exchangers, blower wheels, and gas valves. We check the burner, the ignition, the flue, and the safety switches, then hand you a written price before the work starts. If a furnace has been sitting in a flood-prone crawlspace, we’ll tell you plainly what that means and what the options are. Furnace Repair in San Anselmo

AC Installation in San Anselmo
Because most San Anselmo homes predate forced-air ducting, AC installation here usually means a ductless mini-split system sized for the room layout, the window exposure, and how the afternoon sun lands on the house. We handle the load calculation, the outdoor unit placement, the indoor head locations, and the electrical, then schedule a set install date with a fixed written price. No same-day promises on installation because proper sizing takes time and we will not skip that step. AC Installation in San Anselmo

Pricing for HVAC Company in San Anselmo, CA
Here are the ranges San Anselmo homeowners should expect before any work begins. These are written-price figures, not estimates, which means the number you see on paper before we start is the number you pay.
| Service | Typical range in San Anselmo |
|---|---|
| AC repair (common jobs) | $150-$650 |
| Furnace repair (common jobs) | $150-$700 |
| AC installation (ductless or conventional) | $3,500-$7,500 |
| Seasonal tune-up | $80-$200 |
What pushes a repair toward the top of that range in San Anselmo is access: a furnace in a tight, damp crawlspace near the creek takes longer to work on safely than one in a finished basement, and a mini-split compressor tucked behind old-growth landscaping adds time too. Every visit includes a written price before any work starts, which means you will always know the number before you commit.

What San Anselmo Customers Say
"Furnace tune up before winter. He was careful going in and out, closed the gate behind him every time because of the kids, and cleaned up the work area completely. Calm, thorough guy."
- Marcus Pell"Comfortable in every room now, and not a trace that a crew had been here. Booties, drop cloths, the works. They even wiped down the thermostat they'd handled. Really considerate."
- Lamar Finch"New system install. They protected the hallway floor all the way to the attic and vacuumed after. Worked quietly around my work calls. Not a trace left behind."
- Rosalind Okeke
