HVAC Company in Sausalito, CA
Most HVAC work in Sausalito runs $150-$700 for repairs and $3,500-$7,500 for new AC installation, with pricing shaped by the city’s unique salt-air corrosion, steep hillside lots, and floating-home dock access. We’re Coldharbour Heating & Air, and we dispatch technicians from our San Francisco Bay Area office to handle every job with marine-grade equipment when the location demands it. Call (817) 402-2972 and a live person picks up, 24 hours a day.
Sausalito sits at the mouth of the Golden Gate, where Pacific marine air funnels directly inland. That persistent salt fog keeps summers cool enough that many homeowners never think about mechanical cooling, but it also eats outdoor HVAC components years faster than anywhere else in Marin County. Our crews carry corrosion-resistant parts and spec epoxy-coated condenser coils as standard for waterfront jobs, not as an upgrade.
Why Sausalito Homes Are Different
The housing stock here breaks into two distinct worlds, and each demands a completely different approach.
On the water, Gate 5 Road and Waldo Point Harbor host one of the largest floating-home communities in the United States. Liveaboard HVAC isn’t residential work with a view, it’s marine mechanical. Vibration-tolerant mounting matters because the structure moves. Corrosion-resistant materials are baseline, not optional. Standard aluminum condenser fins at the waterfront can show salt-pitting and airflow loss within two or three seasons, a failure timeline we almost never see in Novato or even Mill Valley a few miles inland. Technicians working these docks spec marine-coated or epoxy-fin condenser coils every time.
On the hills above Bridgeway, most homes are 1940s-1960s cottages and mid-century builds on steep, compact lots. The perpetually mild climate meant central ductwork was rarely installed originally. Retrofitting ducted systems into these terraced, space-constrained structures is usually impractical, which is why ductless mini-split systems dominate modern heating and cooling upgrades in neighborhoods like the Banana Belt and the upper hills.
That same mild climate has led many homeowners to defer HVAC investment for decades. We regularly encounter aging 1950s floor furnaces and wall heaters still in service well past their safe operating life, often in homes where the original owner never saw a reason to replace them.
Our Main Sausalito Services
These are the three calls we handle most often in Sausalito, each with its own dedicated page and local pricing.
AC Repair in Sausalito
AC repair calls in Sausalito are less about failed compressors in July heat, more about systems that sat idle through a damp winter and won’t start when a warm spell finally arrives. Salt corrosion on electrical connections, degraded capacitors, and refrigerant leaks at corroded copper flare fittings are the patterns we see. Because true cooling demand is so brief, many homeowners don’t notice declining performance until the system fails to start at all. Our technicians test every component, hand you a written price before touching a tool, and back the repair with our 365-Day Done Right Promise. AC Repair in Sausalito

Furnace Repair in Sausalito
Furnace repair in Sausalito often means coaxing another season from a 30- or 40-year-old floor furnace or wall heater that the homeowner has been told to replace for years. Igniter failures, cracked heat exchangers, and failed gas valves are common on these aging units. We carry replacement parts for Goodman, Rheem, and York systems, and we stock universal-fit components for obsolete models that manufacturers no longer support. Every repair gets a written guarantee valid for 365 days. Furnace Repair in Sausalito

AC Installation in Sausalito
New AC installation in Sausalito almost always means ductless mini-splits, not conventional central air. The hillside lots lack attic or crawl space for duct runs, and many homes have been expanded in ways that make zoning by room the only practical approach. We size each system to the actual heat load, not the square footage, and we spec corrosion-resistant outdoor units with coated coils for salt-air protection. Installations are scheduled, not same-day, with a written fixed price and all rebate paperwork handled. AC Installation in Sausalito

FAQs About HVAC Company in Sausalito
Most Sausalito calls reach a technician the same day. Live-person phone coverage operates 24 hours a day, 7 days a week, and we prioritize no-heat calls during cold weather. Call (817) 402-2972 for current availability.
Yes. Waldo Point Harbor and other liveaboard communities fall under marine jurisdiction and often require dockmaster notification or harbor-district approval before exterior equipment modifications. We coordinate directly with dock management on these jobs and spec marine-grade mounting and corrosion-resistant materials as standard.
Most hillside homes were built without central ductwork, and retrofitting ducts into steep, terraced lots with compact crawl spaces is rarely practical. Ductless mini-splits provide zoned heating and cooling without invasive construction, making them the dominant upgrade path for Sausalito’s housing stock.

What Sausalito Customers Say
"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
- Celeste Ngo"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann
