Why Kentfield Homes Are Different
Kentfield’s housing stock runs older than what you find in the newer developments east of Highway 101. A lot of the homes along Sir Francis Drake Boulevard and up into the Kent Woodlands neighborhoods were built in the 1950s through the 1970s, which means ductwork sized for older systems, electrical panels that sometimes need a close look before a heat pump goes in, and furnaces tucked into tight crawlspaces rather than roomy mechanical closets.
The microclimate matters too. Mornings here can stay damp and cool well into July, while afternoons climb dry and warm, especially on exposed hillside lots facing south. That swing means cooling equipment gets run hard in stretches, then sits idle for weeks. Systems that aren’t serviced regularly in that pattern tend to develop refrigerant leaks and capacitor failures at the worst possible time. Homes in the flats near Corte Madera Creek also deal with more moisture, which shows up as rust on older furnace cabinets and condenser coils.
Marin County’s building department requires permits for most HVAC replacements, and Kentfield falls under that same jurisdiction. We handle the permit paperwork as part of a heat pump installation, so the job doesn’t stall waiting on an inspection that was never scheduled.
Our Main Kentfield Services
The two calls we get most from Kentfield homeowners are for AC systems that quit during a warm snap and furnaces that won’t fire on the first cold morning. Heat pump installation rounds out the list, and each of these jobs has its own page with specific pricing and details.
AC Repair in Kentfield
Kentfield AC repair calls tend to spike in September and October, when inland heat pushes west and homes that coasted through the fog all summer suddenly need real cooling. The most common fixes are capacitor replacements, contactor swaps, and refrigerant recharges – topping off the cooling fluid your system needs to hit set temperature. We stock common parts for Trane, Lennox, Goodman, and Rheem systems on our trucks. Read the full breakdown on our AC Repair in Kentfield page, including what to check before you call.

Heat Pump Installation in Kentfield
A heat pump replaces both your furnace and AC with one outdoor unit that heats and cools, and it runs on electricity instead of natural gas. That matters in Kentfield, where older homes often have gas furnaces from the 1980s and 1990s nearing the end of their useful life. We size the system to the house, not the old unit, and the price you sign is the price you pay. See our Heat Pump Installation in Kentfield page for equipment options and what installation involves.

Furnace Repair in Kentfield
Furnace problems in Kentfield run the usual gamut: failed igniters, dirty flame sensors, and blower motors that seize after sitting unused since April. Older homes here often have furnaces in crawlspaces, which means moisture exposure and the occasional rodent-chewed wire. If your heat won’t start, we’ll find out why and show you the written price before we touch a single part. Details are on our Furnace Repair in Kentfield page.
