Los Angeles isn’t like other Southern California markets. The 1920s–1950s bungalows and courtyard apartments dense through Koreatown, Echo Park, and the 90001–90010 corridor were built for a climate that didn’t need central cooling. Now they do. Jason Trent, our owner and field supervisor, has spent 16 years solving exactly this problem: how to get modern, efficient air conditioning into homes that were never designed for it. We’ve completed nearly 500 jobs with a 4.7-star average because we don’t treat a 1940s craftsman like a 1990s tract house.
Why Stonegate Heating & Air California Is Los Angeles’s Preferred AC Repair & Installation Company
Our reputation in Los Angeles is built on jobs that other contractors walked away from. The 90036, 90037, 90038, and 90039 ZIP codes are full of homes where the previous HVAC company said “no ductwork, no deal.” We said “let’s design one.” That difference shows in our reviews: 499 verified customers at 4.7 stars, many from central Los Angeles neighborhoods where homeowners finally found a contractor who understood their building.
Jason Trent supervises every project personally. He’s on-site, not in a back office. In Los Angeles, that matters because the field conditions change block by block: a slab-on-grade bungalow in View Park-Windsor Hills needs a different approach than a two-story courtyard building in 90006 with a shallow crawl space. Owner presence means the plan adapts before mistakes get expensive.
We carry parts and factory training for nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Los Angeles has every brand represented somewhere, and “we don’t service that” isn’t an answer we give.
Our AC Repair & Installation Services in Los Angeles
AC Repair
Most repair calls we get from Los Angeles come in two waves: June through August, when systems that haven’t run since October finally get stressed, and September–November, when Santa Ana winds spike temperatures above 100°F with desert-dry air. That second wave breaks a lot of capacitors and overloads compressors that were already marginal. A typical repair in Los Angeles runs $175–$765 depending on whether we’re replacing a capacitor, charging refrigerant, or addressing a compressor issue. We stock common parts for Carrier, Bryant, and American Standard systems so we’re not ordering and waiting.
AC Installation
This is where Los Angeles gets complicated. In central Los Angeles ZIP codes like 90004, 90006, and 90007, the housing stock from the 1920s–1950s was built without ductwork because the historically mild Mediterranean climate made central HVAC unnecessary. As summer heat events intensify and buyers expect cooling, contractors here spend far more time designing first-ever duct systems or ductless mini-split retrofits than simply swapping equipment. That’s a fundamentally different job scope than HVAC work in San Diego or the San Fernando Valley.
We recently serviced a 1940s craftsman cottage on a lot near Vermont Avenue in 90004. The original floor furnace was long retired, and the homeowner wanted central air. We designed a duct system in the attic and installed a 3-ton Trane heat pump with a variable-speed air handler, incorporating a HERS-required duct leakage test per Title 24. The retrofit cost around $6,500 and delivered even cooling without tearing out walls.
AC Replacement
Replacement in Los Angeles often means replacement plus redesign. The existing system may have been installed in the 1980s or 1990s by someone who ran flex duct through a hot attic with minimal insulation, or who sized the unit without accounting for single-pane windows and uninsulated walls common in this older stock. We see a lot of oversized equipment that short-cycles, wastes energy, and dies young. Our replacement jobs include proper Manual J load calculation, duct redesign if needed, and verification that the new system meets Title 24 and SCAQMD Rule 1111 requirements.
Refrigerant Recharge
Los Angeles’s urban heat island pushes afternoon highs 5–10°F above beach communities, which means systems run longer and harder. Low refrigerant from a slow leak becomes obvious fast. We don’t just top off; we leak-test, repair if possible, and recharge to factory spec. With R-22 phased out and R-410A pricing volatile, we also advise Los Angeles homeowners when a recharge is throwing good money after bad versus investing in a new system.

Trusted Brands We Service in Los Angeles
We maintain factory training or deep field experience on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Los Angeles, that breadth matters because the brand in your backyard doesn’t always match the brand your neighbor has, and you shouldn’t have to hunt for a different contractor because you bought a Daikin instead of a Carrier. We stock common capacitors, contactors, and control boards locally for faster turnaround on Los Angeles repair calls.
Common AC Repair & Installation Problems We See in Los Angeles Homes
- Ductless mini-split line-sets run across exterior walls in courtyard apartments. In buildings where four units share a central walk, aesthetics and landlord approval matter. We design line-set routing that minimizes visual impact while maintaining proper refrigerant flow and drainage.
- Attic ductwork in unconditioned space cooks the air before it reaches the vents. Los Angeles attics hit 140°F in August. We specify R-8 insulation minimum and seal all joints with mastic, not tape, because the SCAQMD air basin already struggles with efficiency standards.
- Wall heaters from the 1950s get replaced with heat pumps that the electrical panel can’t support. A 30-amp subpanel in a 90006 courtyard building won’t run a 5-ton air handler. We assess electrical capacity as part of every replacement quote, not as a surprise change order.
- Santa Ana wind events overload systems sized for normal Los Angeles summers. That September–November spike to 100°F+ with single-digit humidity pushes marginal compressors into thermal overload. We see a surge of failure calls every October from homeowners who thought their system was “fine.”

What moves you within these ranges? Three things specific to Los Angeles. First, ductwork: if your 1920s bungalow has none, designing and installing a first-ever system adds labor and material. Second, code compliance: California’s Title 24 requires HERS field verification and duct-leakage testing on virtually every new installation, and SCAQMD Rule 1111 has banned low-efficiency atmospheric furnaces in the South Coast air basin. Every permit-pulled job in Los Angeles carries compliance costs that contractors across state lines never deal with. Third, access: shallow crawl spaces, slab-on-grade construction, and tight lots in Koreatown or Silver Lake can double the time a job takes compared to a suburban home with a full basement.
We don’t quote over the phone for installations. We visit, measure, assess your electrical panel, and give you a written estimate that’s free and no-obligation. Call (855) 467-1888 to schedule.

FAQs — AC Repair & Installation in Los Angeles
Mini-splits are often the better choice for Koreatown bungalows. Ductless systems avoid the problem of routing supply and return ducts through shallow crawl spaces or finished walls, and they let you zone cooling by room rather than cooling the whole house evenly. We’ve installed Daikin and Bryant multi-zone systems in several 90004 and 90006 properties where ductwork would have required significant structural modification. Call (855) 467-1888 and we’ll assess your layout for both options.
Yes, if the system exceeds 3 tons or if you’re replacing an existing central system, Title 24 requires HERS verification and duct-leakage testing even for ductless installations. The HERS rater visits after our work is complete to verify refrigerant charge, airflow, and system performance. We coordinate this as part of our standard installation process; you don’t hire a separate rater. The permit and HERS fees typically add $400–$800 to the total project cost in Los Angeles.
Because compliance isn’t optional in the South Coast air basin, and some contractors bid low by ignoring it until the inspector fails the job. SCAQMD Rule 1111 requires minimum burner efficiency on any new furnace installation, and the required equipment costs more than non-compliant models sold outside the basin. We include compliant equipment and documentation in every Los Angeles quote. The alternative is a failed inspection, red tag, and rework that costs far more than doing it right initially.
Usually not without some electrical upgrade, but the scope varies. A 1950s wall heater typically runs on 120V or 240V at 15–30 amps. A modern heat pump air handler needs 240V at 30–60 amps depending on size. We assess your panel capacity, subpanel configuration, and landlord requirements during our free estimate. In some 90006 buildings, we’ve installed smaller ductless units that run on existing circuits with minimal electrical work. Every building is different; we don’t guess.
If your system is over 12 years old and couldn’t maintain set temperature during last year’s Santa Ana event, replacement is probably the smarter money. Repairing a marginal compressor or adding refrigerant to a leaking system won’t add capacity that wasn’t there. We size replacement systems for Los Angeles’s actual load, including those 100°F+ September days that are becoming more frequent. For systems under 10 years old, a thorough tune-up and possible capacitor or contactor replacement may restore adequate performance. We’ll tell you straight which path makes sense after we inspect.
