Dalton Heating & Air is the HVAC company Sylmar homeowners call when the system won’t cool in August or the heat won’t kick on during a December cold snap. Sylmar sits at the northern edge of the San Fernando Valley, pressed against the San Gabriel Mountains, and that location means summer days over 100°F followed by chilly canyon nights. The equipment here works harder than it does almost anywhere else in Los Angeles, and the housing stock, mostly 1950s-1970s ranch homes on big lots, comes with its own set of challenges. Call (661) 621-3712 when you need a straight answer and a written price.
Why Sylmar Homes Are Different
Most homes in Sylmar were built between the 1950s and 1970s, and many still run on original ducting and older low-efficiency units. Those ranch-style floor plans spread conditioned air across long, single-story layouts, which means the blower and duct system work harder than they would in a compact two-story house. Flat or low-slope roofs are common here too, so rooftop package units show up more often in Sylmar than in other parts of the Valley. Those units bake in direct sun all day, and when the first triple-digit heat wave hits, we see a predictable wave of blown capacitors and failed condenser fan motors, especially in the older foothill neighborhoods where shade is scarce.
Sylmar is also a wind corridor. Santa Ana events push dust through every gap in the building envelope and clog filters fast. Some homeowners on larger equestrian properties deal with even more dust from unpaved areas and horse traffic, which shortens filter life and puts extra strain on coils. Because this is one of the hottest parts of Los Angeles, cooling demand in Sylmar is extreme, and units that are marginally sized struggle to hold set temperature. We size and service equipment with that specific load in mind, not with a generic Southern California assumption.
Styles & brands we work with







Our Main Sylmar Services
Sylmar homeowners reach for two things first when the system fails: fast AC repair in summer and furnace repair when the cold snap hits. Heat pump installation is the third call, and it’s growing as more homes here look for efficient year-round heating and cooling.
AC Repair in Sylmar
When your AC quits on a 100°F afternoon, you need a tech who knows this specific area, not someone learning the map on the way over. We check the usual suspects first: capacitors, contactors, condenser fan motors, and refrigerant levels. In Sylmar’s foothill neighborhoods, we regularly find units running continuously through heat waves with no shade, which wears those parts faster than in cooler parts of the Valley. Get the full breakdown on costs and same-day scheduling on our AC Repair in Sylmar page.

Heat Pump Installation in Sylmar
A heat pump replaces both your AC and furnace with one system, which makes sense for ranch homes where duct layout is already stretched thin. Sylmar’s temperature swings, hot days and cool canyon nights, are actually a good match for a properly sized heat pump, because a well-designed system handles both extremes without overworking. Installations here get sized by a load calculation, not by square footage alone, and on flat-roof homes we often look at rooftop package heat pumps as the practical fit. Details and pricing are on our Heat Pump Installation in Sylmar page.

Furnace Repair in Sylmar
Sylmar doesn’t get the long hard freezes other climates do, but winter nights in the foothills drop fast, and a furnace that won’t fire means a cold house and often a cold morning for kids heading to school. Most furnace repairs in Sylmar come down to igniters, flame sensors, gas valves, or blower motors, and most run $150 to $450 depending on the part. Any repair we make is guaranteed in writing for a full year. See the full breakdown on our Furnace Repair in Sylmar page.
