HVAC Company in Topanga, CA
Dalton Heating & Air handles HVAC work across Topanga, CA, where steep canyon roads, older hillside homes, and salt-tinged coastal air change how heating and cooling systems behave. Most Topanga jobs come down to one of three calls: an AC unit that quit during a heat wave, a furnace that won’t fire on a cold canyon night, or a full heat pump installation for a house that’s ready to get off gas. Our crews arrive with written pricing, factory training across nine major brands, and a one-year written guarantee on every repair. Call (361) 306-9515 and a live person answers, day or night.
Why Topanga Homes Are Different
Topanga is not a flat suburban grid. Homes sit on ridgelines, tuck into shaded canyons, and climb slopes off Old Topanga Canyon Road and Topanga Canyon Boulevard, where access matters as much as the repair itself. A condenser unit on a hillside pad collects dust, chaparral debris, and coastal moisture that accelerates corrosion on coils and electrical connections. Homes built across the 1960s through 1980s often run original ductwork sized for equipment from that era, which means a modern heat pump or AC system has to be matched carefully to what’s already in the walls.
Temperature swings between the canyon floor and the ridges mean two neighbors a mile apart can have genuinely different cooling loads. Coastal fog burns off fast in summer, and afternoons get hot enough that an undersized AC unit runs nonstop and still won’t hold setpoint. We size and diagnose for the actual house, the actual exposure, and the actual duct layout – not a generic square-footage chart.
Our Main Topanga Services
Most Topanga homeowners reach for the phone about one of three systems, depending on the season and the age of the house. Each service below has its own page with pricing, typical repair timelines, and what to expect when we arrive.
AC Repair in Topanga
When a Topanga AC quits in August, it’s usually not one thing. We find failed capacitors, clogged condensate lines, low refrigerant, and contactors burned out from years of canyon heat and salty air. Repairs in Topanga run $150 to $650, and the written quote tells you the exact price before we touch the unit. If the fix doesn’t hold, the guarantee means we come back at no charge – that’s not a pitch, it’s the Garrison Standard. Full details on AC Repair in Topanga.

Heat Pump Installation in Topanga
Topanga homes with older gas furnaces or aging central AC are moving toward heat pumps, and the terrain and permit reality make this a different job than in the valley. Ducted heat pumps replace both heating and cooling in one system; ductless mini-splits solve the old add-on room that never got vents. Install pricing runs $3,500 to $7,500 depending on equipment, ductwork condition, and whether we’re replacing or doing a first-time install. See what a Topanga installation involves on Heat Pump Installation in Topanga.

Furnace Repair in Topanga
Winter nights in the canyon get colder than most people expect, and a furnace that won’t light is a legitimate urgency. We repair gas furnaces across Topanga, from failed ignitors and flame sensors to blower motors and gas valves. Furnace repairs here run $150 to $700. Every repair gets a written price before work begins, and the work carries a written one-year guarantee. The full breakdown is on Furnace Repair in Topanga.

What pushes a Topanga job toward the upper end is access, age of the equipment, and whether ductwork needs modification. Hillside condenser pads, long line sets, and crawlspace or attic work all add labor time. Whatever the number, it’s written down before we start – no “while we’re here” add-ons, no door price that differs from the quote.
