HVAC Service in The Springs, Sonoma Valley

Enviro Heating & Air Conditioning serves The Springs — Boyes Hot Springs, Fetters Hot Springs, Agua Caliente, and El Verano, the unincorporated communities along Highway 12 just north of the City of Sonoma. We bring modern ductless comfort to the Springs' resort-era cottages and handle the detail many contractors miss: permits here go through Permit Sonoma, the county, not Sonoma City Hall. Family-owned since 2008, Diamond Certified, CSLB #928565.

Why is HVAC in The Springs different from the City of Sonoma?

The Springs grew up around the hot-springs resorts of the early 1900s, and its housing stock still shows it: compact cottages and bungalows on small lots, later infill from every decade since, and plenty of homes that never had ductwork — or a cooling system — at all. It's a different inventory than the City of Sonoma's Plaza-area homes a mile south, and it calls for different solutions, usually ductless.

Jurisdiction is the quiet difference-maker. Boyes Hot Springs, Fetters Hot Springs, Agua Caliente, and El Verano are unincorporated Sonoma County, so building and mechanical permits run through Permit Sonoma rather than the city. Straightforward equipment change-outs can often be permitted over the counter, while bigger alterations need plan review — and because Sonoma Clean Power's rebates require a finalized permit, filing with the right office isn't bureaucratic trivia; it's the difference between getting your rebate and forfeiting it.

Climate-wise, the Springs corridor gets true Sonoma Valley summer heat and sits in a wildfire-aware landscape where smoke season is a fact of life. Efficient cooling sized to small cottage footprints, plus filtration that keeps smoke out, is the combination we design for here.

What goes wrong with The Springs homes?

County permits, not city

The Springs is unincorporated — permits go through Permit Sonoma. We file with the county, schedule the inspection, and keep the paperwork rebate-ready.

Cottages without ducts

Many Springs homes were built duct-free in the resort era. Single- and multi-zone ductless heat pumps deliver heating and cooling sized to compact footprints without invasive construction.

Valley heat and smoke season

Sonoma Valley summers run hot and fire season brings smoke down the corridor. Right-sized cooling plus high-MERV filtration keeps small homes comfortable and the air inside clean.

Do Springs homeowners qualify for Sonoma Clean Power rebates?

Yes — The Springs is in PG&E delivery territory with Sonoma Clean Power as the local electricity provider. Verified July 2026: SCP pays $1,000 for a qualifying heat pump heating-and-cooling system, and CARE/FERA-enrolled customers can receive 50% of remaining project costs up to $10,000. The catch that bites unincorporated communities: SCP requires a finalized permit — for The Springs that means Permit Sonoma, the county office — and an application within 90 days of completion. Enviro files the county permit and the rebate paperwork as part of the job. The federal 25C credit ended December 31, 2025, and statewide TECH/HEEHRA rebates are fully reserved.

The Springs questions we hear most

Do I pull a City of Sonoma or Sonoma County permit in Boyes Hot Springs?

County. Boyes Hot Springs, Fetters Hot Springs, Agua Caliente, and El Verano are unincorporated, so HVAC permits go through Permit Sonoma. Enviro files with the county and schedules the inspection — you don't have to sort out the jurisdiction yourself.

Can you cool a small Springs cottage that has no ductwork?

Yes — a single-zone ductless heat pump is usually the right-sized answer for a compact cottage, and multi-zone systems cover larger or added-onto homes. You get efficient heating and cooling from one system without cutting duct chases into a small house.

Will an unpermitted install cost me the Sonoma Clean Power rebate?

Yes. SCP's rebates require a finalized permit and an application within 90 days of completion — an unpermitted job is ineligible. We build the Permit Sonoma filing into every Springs project so the rebate stays on the table.

How do Springs homes handle wildfire-smoke days?

With whole-home filtration at the air handler, or filtration built into a ductless system, plus a maintained blower that can run continuously when the air outside is bad. We size filtration to the home so clean air doesn't come at the cost of airflow.

Do you actually come out to The Springs, or just the city of Sonoma?

Both — the Highway 12 corridor through Boyes Hot Springs and Agua Caliente is on our regular Sonoma Valley routes from Rohnert Park, along with the Plaza area and the wider valley. We've served Sonoma Valley homes since 2008.
