AfterHVAC Company in Kentfield, CA
Kentfield HVAC work is shaped by two forces that rarely show up on the same job anywhere else in the Bay Area: a valley that pulls more than 45 inches of rain in a wet year, and summer days that can push past 100°F when offshore winds collapse the marine layer. Homes here were largely built between the 1930s and 1980s, most without central air, on lots that climb steeply toward Mt. Tamalpais. We service all three jobs Kentfield homeowners call about most, AC repair, furnace repair, and full AC installation, with a written price before any work begins and a 365-Day Done Right Promise behind every visit. Call (747) 966-3037 and a live person picks up, any hour, any day.
Why Kentfield Homes Are Different
Kentfield sits in the Ross Valley at the foot of Mt. Tamalpais, and the geography does two things to HVAC equipment. First, orographic lift off the mountain pulls 45 to 50-plus inches of rain into a narrow valley in a typical wet season. That moisture doesn’t stay outside. It works into crawl spaces, saturates the air around duct joints, and condenses inside uninsulated ductwork that was never designed for those humidity loads. Second, when Diablo winds set up offshore, the marine layer collapses and valley temperatures spike into the upper 90s and low 100s. Homes that were comfortable in July suddenly can’t hold 78°F in August, because the cooling load was never part of the original design.
The housing stock splits into two distinct challenges. Valley-floor ranches and craftsman homes from the 1930s through 1960s tend to have narrow mechanical closets and original duct runs laid through damp crawl spaces. Kent Woodlands estates, built mainly from the 1950s into the 1980s, climb steep grades where equipment pads sit on slopes and duct chases run through attics with full solar gain. On those hillside lots, we often find ductwork that is undersized for any serious cooling load and riddled with joint failures caused by years of winter condensation. That’s why so many Kentfield retrofits move toward ductless mini-split systems rather than forcing a traditional forced-air install into a house that was never framed for one.
Permitting in unincorporated Marin County, which covers Kentfield, can add time to any equipment change-out. It’s not unusual for a furnace replacement on a hillside property to need setback or noise review before the county signs off. We handle the paperwork, but homeowners should expect the process to move at Marin’s pace, not the pace of faster, denser jurisdictions nearby.
Our Main Kentfield Services
Most Kentfield calls fall into three buckets. Two are fixes, one is a planned upgrade, and all three are shaped by the valley’s humidity swings. Here’s what each involves and where to read the full Kentfield breakdown.
AC Repair in Kentfield
AC repair in Kentfield is rarely a simple capacitor swap. The same system that ran fine through a mild June gets hammered when offshore wind collapses the marine layer and the valley jumps past 95°F. We get calls for compressors that trip on thermal overload, condensate lines backed up from months of heavy rainfall, and coils that never got a chance to dry out between seasons. In Kent Woodlands, the problem is often the duct side, joints pulled apart by swelling and drying cycles, leaking cooled air into crawl spaces before it ever reaches a bedroom. We diagnose the system as a whole, not just the box, and stock common parts for our brands including Trane, Lennox, Goodman, and Rheem on our trucks. Read more at AC Repair in Kentfield.
Furnace Repair in Kentfield
Kentfield furnaces run hard through long, wet winters. They cycle against damp outside air, pull moisture through returns in dirt-floor crawl spaces, and sit in homes where the original ductwork has been soaking in valley humidity for five or six decades. Common cold-season failures here include rusted igniters, condensate pumps that clog with debris and shut the system down, and heat exchangers that corrode faster than the manufacturer’s expected lifespan because of the airborne moisture. A furnace repair in Kentfield means checking the whole airflow path, not just the failing part. If the furnace is finished, we’ll tell you plainly, because the decision between repair and replacement should never be a surprise. See Furnace Repair in Kentfield for the full detail.
AC Installation in Kentfield
AC installation in Kentfield is a retrofit project more often than a builder-grade swap. Most of these homes never had central cooling, and the challenge is putting a system into a house that was framed for fog, not for 100-degree offshore wind days. On steep lots, we often recommend ductless mini-splits because they avoid the crawl-space duct problems that plague original ranch homes. In Kent Woodlands, siting the outdoor unit means working with slopes, setbacks, and Marin County review. We size the equipment with a proper load calculation, quote a written fixed price, and set a firm install date. We also pull and close permits on every install.

FAQs About HVAC Company in Kentfield
Most Kentfield calls get a same-day or next-morning appointment, and we’re usually on site within 24 to 48 hours across the full service area. For a furnace that won’t light or an AC that quit during a 100°F offshore-wind day, call and a live person answers, no voicemail queue.
Yes, in most cases. Kentfield sits in unincorporated Marin County, and equipment change-outs and new installs typically require county permits. We pull and close permits on every installation, and we handle the county paperwork for repairs that trigger a permit, so you don’t have to navigate the building department.
We do. Hillside lots are a regular part of the job in Kent Woodlands, and that shapes everything from where the equipment sits to how we route ductwork. We plan for slope access, Marin County setback rules, and the reality that steep lots often need ductless systems rather than long forced-air duct runs.

What Kentfield Customers Say
"Good repair and a very tidy, respectful tech. The appointment window was wide and he came near the end of it, but he texted ahead. Work itself was clean and done right."
- Nadine Oakley"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
