AC installation in North Hollywood

About AC installation in North Hollywood

Short answer

A central AC replacement in North Hollywood starts at $7,900 installed with Airwork, including the permit from LA Department of Building and Safety (LADBS), HERS testing and haul-away. We size it with a Manual J load calculation and quote a fixed price in writing.

What we see in North Hollywood homes

A new system in North Hollywood is usually a fit problem. Post-war lots are narrow, so the condenser has to fit the same side yard or move to the back. The quietest models make sense where a neighbor's window is close, because LA's noise rule applies at the property line. In houses with a back unit or a converted garage, one system rarely serves everything well. A separate mini-split for the added space usually beats stretching the main ducts. We size each part of the house from a room-by-room load calculation.

Townhomes need a different design. Three floors on one system leave the top floor hot and the ground floor cold. A two-zone system with motorized dampers, or a ductless head for the top bedroom, evens it out. Owners of older apartment buildings can replace wall heaters and window units with ductless heat pumps one unit at a time. Permit and HERS paperwork are part of the price, not an add-on. Before ordering, we check the panel, since 1940s houses often still have 60 or 100 amp service.

Converted garages and back units often have no ducts and need their own system. A ductless heat pump there adds heating and cooling without touching the main house. Older duplexes may share one electrical service, which limits how much new equipment can be added. We check both units' loads before quoting. Condensers on flat garage roofs need proper supports and room for service.

Where the equipment goes in North Hollywood homes

Post-war side yards are narrow, so the new condenser often has to be smaller and quieter than the old one. A spot near the back of the side yard keeps it away from the neighbor's bedroom. Flat garage roofs can hold a condenser if the roof is sound and the unit sits on proper supports. Townhome condensers usually go on a roof deck or a ground pad assigned to each unit. Inside, attic air handlers need a platform and a clear path from the hatch, which older houses often lack.

Questions to settle before a North Hollywood install

• Does the back unit or converted garage need its own system?
• Is the panel 60 or 100 amps, and does it need an upgrade?
• Can the top floor of a townhome get its own zone or ductless head?
• Will the new condenser meet the City of LA noise limit at the property line?
• Is a heat pump worth it with LADWP's rebate, compared with a new AC?

After the install

The LADBS inspector and a HERS rater check the system, and we meet both. LADWP's rebate application goes in after the final inspection. You get the permit card, test results and warranty registration together.

North Hollywood replacements often happen in duplexes and small multifamily buildings, where each unit has its own system. Owners can replace several systems in one project, which keeps permits and crane days efficient. For single-family homes from the 1950s and 1960s, the attic usually has room for a horizontal air handler and new ductwork. We check the attic before quoting, not on install day.

LADWP pays far more for heat pumps than for standard AC, so most North Hollywood quotes include a heat pump option. The rebate can make a heat pump cost about the same as an AC and a new furnace. If your gas furnace is also aging, replacing both with one system is often the better deal.

The NOAA weather station in North Hollywood, Hollywood Burbank Airport, averaged 26 days a year at 95°F or hotter and 7 days at 100°F or hotter in 2016-2025. Its hottest reading was 114°F on July 6, 2018.

California requires a permit for a new or replacement central system, and most replacements also need a third-party HERS test of duct leakage and system performance. We pull the permit, schedule the HERS rater and meet the inspector.

LADBS issues express permits online, with no plan check, for replacing an AC with one of the same size and type and for adding equipment of 5 tons or less, so a standard change-out permit can be issued the day it is requested. Systems that need plan review go through ePlanLA.

In North Hollywood (ZIP codes 91601, 91605 and 91606), 38% of homes were built before 1960 and 68% before 1980; 60% of households heat with natural gas, and 32% of homes are detached single-family houses.

North Hollywood is served by LADWP. Up to $2,500 per ton for qualifying heat pumps purchased and installed from November 1, 2025. The amount depends on SEER2 and HSPF2 ratings. That is far more than for a standard AC, so we price both options.
