AfterHVAC Company in Sonoma, CA
Dalton Heating & Air is the HVAC company Sonoma homeowners call when a system fails and the fix needs to hold. Most homes here fall into two camps: older ranch and Spanish-style builds from the 1950s through 1980s, and newer construction up in the hills where heat pumps are becoming the standard. Both present different challenges, and both need technicians who show up inside the stated window, put the price in writing before touching a unit, and stand behind the work for a full year. Call (361) 306-9515 and a live person answers, day or night.
Why Sonoma Homes Are Different
Sonoma’s climate swings harder than most people expect. Summer afternoons routinely push into the 90s through July and August, and winter nights in the north end of town regularly dip into the mid-30s. A system sized for coastal fog fails the moment the inland heat settles in, and we see that failure pattern constantly in neighborhoods like Eastside and Diamond A. Homes in the Boyes Boulevard corridor tend to be older, with ductwork original to the house, which means airflow issues and undersized returns complicate what looks like a simple repair. The terrain matters too: Sonoma’s hills mean variable shading, drainage patterns that stress outdoor condenser pads, and occasional wildfire-related ash buildup that clogs outdoor coils faster than the rated interval. The city’s planning department requires permits for HVAC replacement work, and many HOAs in newer developments west of Broadway add their own noise and placement restrictions on outdoor units. A crew that doesn’t know those rules will leave a homeowner holding a code violation.
Our Main Sonoma Services
Three jobs make up the bulk of what we handle across Sonoma: cooling repairs during summer, heat pump installations as older systems age out, and furnace work when the mornings turn cold. Each has its own page with full pricing detail.
AC Repair in Sonoma
When a condenser stops in August heat, the diagnosis has to be fast and the fix has to last. In Sonoma that often means a refrigerant recharge, a failed capacitor, or a contactor that wore out during a stretch of heavy cycling. Older units along the Fryer Creek area run R-22, which is being phased out and whose remaining supply costs more every season. We arrive with capacitors, contactors, and common replacement parts on the truck, so most repairs finish same-visit. If your cooling system is struggling, read AC Repair in Sonoma for full pricing and what the repair includes.
Heat Pump Installation in Sonoma
Sonoma’s temperature range suits heat pumps better than almost any climate in the Bay Area: mild enough winters that a heat pump handles heating without backup strips, hot enough summers that the cooling side earns its keep. Newer hillside homes in the Diamond A and Creekside areas increasingly run all-electric, and we install systems from Goodman, Rheem, York, and Daikin with load calculations sized to the actual house, not a rule of thumb. Full detail on process and pricing is on the Heat Pump Installation in Sonoma page.
Furnace Repair in Sonoma
Furnace failures in Sonoma cluster around ignition systems, gas valves, and blower motors. When a furnace won’t light on a 36-degree morning, the issue is frequently a dirty flame sensor or a failing ignitor, both of which we stock on the truck. Older homes near the Plaza have furnaces that predate modern safety standards, and those jobs require a level of care with gas lines and venting that dictates when a repair is worth making versus when replacement is the responsible call. See Furnace Repair in Sonoma for cost ranges and what’s covered.

What pushes a Sonoma repair toward the top of those ranges is usually one of three things: access to the equipment (crawlspaces and steep hillside yards cost labor time), the age of the system (older units take longer to diagnose), and part availability if a unit is beyond the brands we typically stock. Whatever the number ends up being, you’ll see it in writing before any work begins. That’s The Garrison Standard, and it applies to every job without exception.

FAQs About HVAC Company in Sonoma
Same-day response is typical for calls inside Sonoma city limits when the request involves no heat or no cooling in extreme temperatures. Call (361) 306-9515 and a live person answers 24/7, not a voicemail queue. We’ll give you a straight arrival window on that first call.
Yes for equipment replacement and new installation, and the work must meet the city’s current mechanical code. We pull the necessary permits and schedule inspections as part of the job when the scope requires it. Repairs to existing equipment generally don’t need a permit.
We do. Several HOAs in western Sonoma neighborhoods restrict condenser and heat pump placement based on noise and visibility. We factor those restrictions into the placement plan before installation day, so the unit passes HOA review without rework.
