New AC Installation in Sherman Oaks, CA

New central AC installation in Sherman Oaks costs $5,500 to $13,000 in 2026 for a typical 2.5-to-5-ton split system, fully permitted and Title 24 compliant. EA Mechanical handles Manual J load calculations, ductwork design, electrical panel verification, and City of LA permit and HERS testing as a single project. Sherman Oaks dispatch from our Tujunga shop runs about 25 minutes via the 170 to the 101 West. Call (818) 988-9060.

Sherman Oaks installs split into two distinct profiles. On the flat Magnolia corridor and the Dickens-Kester ranch homes, sizing typically lands at 3 to 4 tons for the 1,800-to-2,400-square-foot single-story floor plans. On the multi-level hillside properties south of Ventura — Sherman Oaks Hills, the Magnolia north slope — Manual J load calculations almost always recommend zoned ducted systems or paired furnace + dedicated upstairs mini-split because a single-zone system cannot keep upstairs bedrooms within 4°F of setpoint when the thermostat is on the main level.

We are an independent installer — not contractually locked to a single brand. For most Sherman Oaks installs we recommend Carrier, Lennox, Trane, or Mitsubishi mini-splits depending on the lot constraints, the LADWP rebate that fits, and your budget. See /carrier/, /lennox/, and /mitsubishi-ductless/ for brand details, and /heat-pumps/ for the heat-pump electrification path that unlocks the LADWP $2,500/ton rebate.

Manual J Sizing for Sherman Oaks Hills Two-Story Homes

The single biggest install mistake on a Sherman Oaks Hills two-story is assuming one thermostat and one zone can deliver comfort to both floors. Hot air rises and pools on the upper level while the main-floor thermostat reads satisfied — the AC short-cycles, the upstairs bedrooms stay 8 to 12°F warmer, and the homeowner gets a system that runs constantly without ever feeling right. We perform Manual J on every Sherman Oaks Hills install and almost always specify either a zoning system with motorized dampers per floor or a paired downstairs central + upstairs ductless mini-split.

Sherman Oaks Hills lots also impose condenser-placement constraints: steep grade, narrow side yards, and noise-sensitive neighbors close to the property line. We design for variable-speed condensers rated below 60 dB at the property line and place pads with proper vibration isolation. For the steepest hillside lots we coordinate crane delivery on the install day.

• Manual J load calculation — sizes the system to your home's actual heat load, not a square-footage rule of thumb
• Zoning system specification — motorized dampers per floor for hillside two-stories or paired central + ductless mini-split
• Hillside condenser pad placement — vibration isolation, noise rating, side-yard setback compliance
• Electrical panel verification — most Sherman Oaks installs need a dedicated 240V circuit; 100A panels often need sub-panel work

City of LA Permits, Title 24, and the LADWP Rebate Stack

Sherman Oaks falls under City of LA permitting and LADWP utility service. Mechanical permits process in 5 to 10 business days; California Title 24 mandates a HERS test for duct leakage and refrigerant charge on every new install. We pull the permit, schedule the HERS rater, and stand inspection. LADWP pays $100 to $120/ton for qualifying SEER2 16 AC and up to $2,500/ton for heat-pump installs — see /hvac-rebates-tax-credits/ for the full current stack and /blog/heat-pump-installation-cost-los-angeles-2026/ for the heat-pump pricing breakdown.
