Expert heat pump installation, repair, and replacement built for Mill Valley's foggy canyons, hillside lots, and older homes.
Mill Valley's redwood canyons and ridgetops create a comfort puzzle no single thermostat setting solves: damp, fog-cooled afternoons in Old Mill and Cascade Canyon, warmer pockets up on the hillsides, and a housing stock of pre-1970 cottages and craftsman homes that were never built with central air. A right-sized heat pump heats, cools, and quietly pulls humidity out of those shaded rooms in one efficient electric system. John Owens Services has sized, installed, and repaired these systems across Marin since 1986, and we know what the terrain, the tight lots, and the older electrical panels around here actually demand.
Cost depends on whether you choose a ducted or ductless system, your home's electrical capacity, and how many zones you need for those split-level and hillside layouts. We give a clear, itemized quote on site and help you apply Marin Clean Energy, BayREN, and TECH rebates to bring the price down.
Yes. Our trucks are fully stocked, so most heat pump repairs in Mill Valley are diagnosed and fixed the same day. We're licensed (CA #501853), local, and used to the steep, tight-access lots around the canyon.
Often, yes — replacing an aging gas furnace or electric wall heaters with a modern heat pump cuts energy bills, adds cooling for the warmer hillside days, and dehumidifies the damp canyon rooms. We assess your panel, ducts, and layout before recommending replacement so you only upgrade what's needed.
Absolutely. Today's cold-climate heat pumps heat efficiently well below Marin's mildest winter lows and, unlike old furnaces, also remove the moisture that makes shaded canyon homes feel chilly. Proper sizing is the key, and that's exactly what our load calculations get right.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
