Santa Clarita Valley · Los Angeles County
Installing a new AC in Stevenson Ranch, CA is a design job before it is a labor job. DC Air and Heating installs central air conditioners, heat pumps, and complete AC-and-furnace systems across Stevenson Ranch, Los Angeles County — sized by Manual J load calculation, permitted with the county, HERS-tested where required, and commissioned with documented readings. Our crews reach most Stevenson Ranch addresses in about 45–60 minutes.
A full AC installation includes equipment selection matched by AHRI, removal and haul-away of the old system, a new pad and condenser set with proper clearances, a new evaporator coil or air handler, line set replaced or flushed and pressure tested, a new filter drier, plenum and duct transitions sealed with mastic, electrical disconnect and whip brought to code, a new thermostat, nitrogen purge and deep vacuum to 500 microns, and full charge verification by weight and subcooling.
Equipment that survives Stevenson Ranch has to handle hillside sun exposure on large two-story homes. Around The Ranch and Pico Canyon Road we plan installations around multi-zone systems out of balance and long attic duct runs losing capacity, which changes condenser placement, coil-guard choice, and line-set routing. For homes in 91381 we typically recommend a two-stage or variable-speed condenser so the system runs long, low-speed cycles instead of hammering on and off through a 105°F afternoon.
Installed AC pricing in Stevenson Ranch, CA generally lands between $11,600 and $29,400 for a complete system, driven by tonnage, efficiency tier, and any electrical or duct work. AC-and-furnace bundles for a 5-ton home run $14,490–$18,490 good, $16,490–$21,490 better, and $18,990–$24,990 best, with each step down in tonnage reducing the range. Synchrony 0% APR for 24 months is available, and our Instant Quote tool prices your exact options in about a minute.
Stevenson Ranch is unincorporated Los Angeles County even though it reads as part of Santa Clarita, so permits go to the County counter rather than the city — a detail that changes inspection scheduling on a replacement. The housing is almost entirely 1990s and later, which means the original equipment is now at or past its expected service life and the failures we see are end-of-life failures rather than neglect: compressors, coils, and control boards. Two-story floorplans with a single zone are the norm, so upstairs balance is the most frequent complaint. It is one of our longer drives.
We are a locally owned Los Angeles County HVAC contractor headquartered at 5345 West Avenue M8 in Lancaster — about 38–46 miles from Stevenson Ranch, CA, or 45–60 minutes in normal traffic. That proximity is why same-day service is realistic here rather than aspirational. Every technician lives in the Santa Clarita Valley, every price is flat-rate and shown in writing before work starts, and every repair carries a one-year labor warranty.

That comes from a Manual J calculation, not square footage alone. Insulation, window orientation, ceiling height, duct condition, and Stevenson Ranch's design temperature all move the number. Oversizing is the most common mistake we correct in the Santa Clarita Valley — it short-cycles and never dehumidifies. See A/C System Maintenance in Stevenson Ranch, CA.

"Rick and his crew went above and beyond when our aircon failed in the heat of August. Rick bought a new mobile air conditioner to cool our house over the weekend without us even agreeing to buy from DC Air. Honest, fair, and professional. Highly recommend!"

"This company treats you like family. We have an old mobile with a badly installed heater, most companies want nothing to do with our situation, Rick and his crew went the extra mile and got us going with AC too. Rick can master any issue and he seems to do it daily. Thank you Rick and crew!!!"
