Dalton Heating & Air handles HVAC work in Sierra Madre, CA with written pricing before any work begins and a full-year written guarantee on every repair.

We’re the crew homeowners call when they want a straight answer on cost and a technician who shows up inside the stated window. You can reach a live person at (361) 306-9515 any hour.
Why Sierra Madre Homes Are Different
Sierra Madre sits right against the San Gabriel Mountains, and that position shapes every HVAC decision in town. Summer heat stacks up against the foothills, and homes on the upper streets near Bailey Canyon and Mount Wilson Trail get direct afternoon sun with no coastal breeze to soften it. In winter, canyon air settles cold overnight, so a furnace has to cycle reliably through short, sharp temperature drops rather than long deep freezes.
Housing stock matters here. Many homes in central Sierra Madre were built between the 1920s and 1960s, which means wall cavities are tighter, duct runs were retrofitted rather than designed in, and electrical panels were sized for a different era. When we run a heat pump load calculation on a 1940s bungalow off Baldwin Avenue, we’re accounting for original windows, minimal insulation, and attic access that may not have seen a full inspection in two decades. That’s the difference between a system that keeps up and one that runs constantly and still misses the mark.
Permits are a real part of the equation in Sierra Madre. The city has specific requirements for equipment placement, noise levels, and sometimes historical review on older properties. We handle that paperwork as part of the job, and the price is in writing before we start. No surprises at the door.
Our Main Sierra Madre Services
Sierra Madre homeowners call us most about two things: an AC unit that quit during a heat wave, and a furnace that won’t fire on the first cold night. Each service has its own page with full pricing and details.
AC Repair in Sierra Madre
When an AC fails in Sierra Madre in August, it’s not just uncomfortable, it’s a health issue for older residents and anyone with respiratory problems. Most repairs run $150 to $650 depending on the part, and we diagnose first, then put the price in writing before touching a component. Common Sierra Madre failures include capacitor burnout from constant afternoon cycling, refrigerant leaks on older R-22 systems, and clogged condensate lines from foothill dust. See the full breakdown on our AC Repair in Sierra Madre page.

Heat Pump Installation in Sierra Madre
Heat pumps make sense for Sierra Madre’s climate because they handle both cooling and heating in one unit, and the foothill temperature range is well within their efficiency sweet spot. Installation involves a load calculation on the specific home, duct assessment, and proper sizing rather than a one-size-fits-all swap. Older Sierra Madre homes often need electrical panel upgrades to support a modern heat pump, and we factor that into the written quote. Details and full pricing are on the Heat Pump Installation in Sierra Madre page.

Furnace Repair in Sierra Madre
A furnace that won’t light on a cold Sierra Madre night is an urgent call. Most furnace repairs run $150 to $700, with common issues being failed igniters, dirty flame sensors, and cracked heat exchangers on older units. Sierra Madre’s steep streets mean some furnaces sit in tight crawlspaces or attic corners that require careful access and cleanup after the job. We guarantee every repair in writing for a full year, and if it fails in that window, we return at no charge. Read the full breakdown on the Furnace Repair in Sierra Madre page.
