AfterHVAC Company in Sebastopol, CA
Most Sebastopol homes were built without air conditioning at all, and many still rely on a single wall heater or vintage floor furnace as their only heat source. We’re Coldharbour Heating & Air, and our Sebastopol work centers on retrofitting pre-1970 craftsman bungalows and rural farmhouses with ductless mini-split systems, repairing the few existing heat pumps in town, and keeping those old wall heaters running through damp, foggy winters. If you need help now, call us at (817) 402-2972. A live person answers 24 hours a day.
Why Sebastopol Homes Are Different
Sebastopol sits about 10-12 miles from the Pacific, deep in Sonoma County’s coastal fog belt. July highs typically reach only the mid-60s to low 70s, dramatically cooler than Santa Rosa just 7 miles east. That mild microclimate means air conditioning was rarely installed in original construction, and the persistent marine layer keeps humidity higher year-round than inland markets.
The housing stock tells the rest of the story. Pre-1970 craftsman bungalows, Victorian cottages, and old Gravenstein apple-orchard farmhouses dominate. Nearly all were built without central ductwork. We regularly walk into homes where an Empire or Williams wall heater from the 1960s is the sole heat source for 1,200 square feet. The damp winters accelerate corrosion on outdoor condenser coils, so coil cleaning and corrosion-resistant equipment selection matter more here than in drier parts of Sonoma County.
Perhaps most distinctively, Sebastopol has one of California’s most aggressively pro-electrification, anti-gas customer bases. Homeowners frequently refuse new gas equipment outright, requiring us to design all-electric mini-split solutions around structures with no duct chases and often undersized electrical panels. That combination, specific to this town, shapes nearly every job we quote.
Our Main Sebastopol Services
Sebastopol homeowners call us most often for heating repairs on older systems and for mini-split installations in homes that have never had central air. Here’s what each job looks like locally.
AC Repair in Sebastopol
True AC repair calls in Sebastopol are relatively rare because so few homes have traditional central air. When we do get them, it’s usually for a heat pump or ductless mini-split that handles both heating and cooling. The coastal humidity stresses outdoor coils, so we often find refrigerant leaks or clogged condensate drains. Our technicians carry replacement coils, compressors, and refrigerant for Goodman, Rheem, and Daikin systems, and most repairs finish same day. AC Repair in Sebastopol
Furnace Repair in Sebastopol
Furnace repair here means something different than in most California markets. We service wall heaters, floor furnaces, and the occasional ducted gas furnace in newer additions. Igniter failures, blower motor burnout, and corroded heat exchangers are common in units exposed to decades of fog-laden air. Before any work begins, we hand you a written price. Every repair carries our 365-Day Done Right Promise in writing. Furnace Repair in Sebastopol
AC Installation in Sebastopol
AC installation in Sebastopol is almost exclusively ductless mini-split retrofit work. We size each system to the home’s actual heat loss, upgrade electrical panels when needed, and mount outdoor units on corrosion-resistant pads or wall brackets to keep them above the damp ground. Many homeowners pair installation with heat-pump rebates; we handle the paperwork. Installations are scheduled, not same-day, with a fixed written price agreed before ordering equipment.

Yes. Sonoma County requires permits for all new HVAC installations, including ductless mini-splits. We pull the permit, schedule the inspection, and handle the paperwork as part of the job. You don’t need to visit the county office.
Absolutely. That describes most Sebastopol homes we enter. Ductless mini-splits need only a small hole through the wall for refrigerant lines and power. We size the system, upgrade electrical if needed, and install without any duct construction.

What Sebastopol 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."
