We’re Stonegate Heating & Air California, and we’ve spent 16 years working in climates like Calabasas’s — the inland valley heat that hits 10–15 degrees harder than Malibu, the Santa Ana wind spikes, the wildfire smoke that tests every filtration system. Jason Trent, our owner and Field Supervisor, personally oversees jobs here. We know the 91302 and 91372 ZIP codes, the gated communities off Las Virgenes Road, and the specific code requirements that catch out-of-area contractors off guard.

Why Stonegate Heating & Air California Is Calabasas’s Preferred AC Repair & Installation Company
Our reputation in Calabasas was built job by job, not through marketing campaigns. Nearly 500 verified reviews at a 4.7-star average tell the story — homeowners and property managers who needed someone accountable and found it with Jason Trent on-site.
Calabasas isn’t a quick in-and-out market for us. The homes here demand precision. A 6,000-square-foot custom build with vaulted ceilings in The Oaks needs a contractor who understands multi-zone load calculations, not a tech running through a checklist. Jason supervises every project, which means the person making decisions is the same one walking your attic and checking line-set sizing.
We stock parts locally for the nine brands we service — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That inventory matters when your compressor fails on a Saturday in August and the Santa Ana winds are pushing 100°F. We don’t tell you to wait for a warehouse shipment.
Our response time to Calabasas is built into our dispatch structure. We know the Mulholland corridor traffic patterns, the difference between a gated community access call and a standard residential route, and the permit requirements at LA County Building and Safety that can delay a replacement if handled wrong the first time.
Our AC Repair & Installation Services in Calabasas
AC Repair
Calabasas summers punish equipment. Capacitor failure is the call we get most often in July and August, when triple-digit heat pushes electrical components past their tolerance. A typical AC repair in Calabasas runs $150–$650 depending on whether we’re replacing a capacitor, addressing a refrigerant leak, or troubleshooting a compressor that’s short-cycling. We recently retrofitted a multi-zone Daikin system in a 2019 custom build off Las Virgenes Road, where the original single-speed unit couldn’t keep up with the 105°F summer heat. The homeowners wanted whisper-quiet operation for their great room, so we installed variable-speed condensers with ember-resistant vent terminations to satisfy Chapter 7A and matched the line sets exactly to the existing copper runs.

AC Installation
New construction and post-Woolsey rebuilds in Calabasas face a dual regulatory burden that doesn’t apply with the same force in lower fire-hazard zones like Agoura Hills or Thousand Oaks. Every installation must satisfy California Title 24 energy compliance and CBC Chapter 7A ember-resistant vent requirements. Plan-check reviewers at LA County Building and Safety enforce Chapter 7A strictly — combustion-air intakes and exhaust terminations must use specifically listed, mesh-screened vent products. Generic vent caps fail plan-check and stall permits. We handle this documentation as part of our standard process, not as an afterthought. AC installation in Calabasas ranges from $3,500–$7,500 for most residential systems, with larger custom homes at the higher end due to multi-zone equipment and extended line sets.

AC Replacement
Most original Calabasas housing stock was built between the mid-1980s and early 2000s with single-stage equipment that’s now past its efficient lifespan. Replacing these units isn’t a swap — it’s a re-engineering. Vaulted great rooms, multi-story layouts, and 3,500–8,000+ square foot floor plans routinely require zoned-ducted or variable-refrigerant systems with careful Manual J load calculations. Sizing equipment without that calculation leads to oversized units that short-cycle in Calabasas’s wide temperature swings from 100°F summer days to 40°F winter nights. We measure every room, account for your home’s specific envelope, and specify equipment that handles both extremes without wasting energy.

Refrigerant Recharge
Low refrigerant in Calabasas usually means a leak, not normal consumption. The Santa Ana wind events that pound this area can stress outdoor coils and line-set connections, particularly on older R-22 systems still common in pre-2005 builds. We locate the leak source before recharging — adding refrigerant without fixing the underlying problem is a temporary patch that costs you twice. Our recharges include pressure testing and electronic leak detection, with documentation you can use for warranty or resale purposes.

Capacitor Replacement
Capacitor failure spikes in Calabasas every August. The combination of sustained 100°F+ heat and voltage fluctuations during peak demand degrades these components faster than in milder coastal zones. We carry dual-run and single capacitors for all nine brands we service, and we check your contactor and wiring while we’re in the electrical compartment — heat stress rarely affects just one component.

Trusted Brands We Service in Calabasas
We maintain factory-trained experience on nine leading HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Our Calabasas customers don’t get turned away because of a badge on their condenser. We stock capacitors, contactors, and control boards for Carrier, Trane, and Lennox locally, which means same-day repair for most failures rather than a multi-day parts hunt. For Daikin and other inverter-driven systems increasingly common in post-Woolsey rebuilds, we source components through authorized channels with verified compatibility — no generic substitutions that void warranties or trigger fault codes.
Common AC Repair & Installation Problems We See in Calabasas Homes
- Non-compliant vent caps on combustion-air intakes. Installing standard vent caps fails plan-check at LA County Building and Safety because they don’t meet Chapter 7A ember-resistant mesh requirements. We’ve seen out-of-area contractors submit generic caps and stall permits for weeks. We specify listed products from the start.
- Oversized equipment from skipped Manual J calculations. Calabasas’s temperature swing — 100°F days to 40°F nights — exposes bad sizing fast. Oversized units short-cycle, fail to dehumidify, and die prematurely. We calculate every load.
- Mismatched refrigerant line sets in custom homes. Using generic line sets that don’t match the exact length and diameter of the original run causes performance issues in vaulted great rooms with multi-story layouts. We measure, match, and pressure-test every connection.
- Inadequate filtration during Santa Ana smoke events. Standard 1-inch pleated filters don’t handle the particle load from wildfire smoke that pushes through Calabasas’s wind corridors. We specify MERV-rated media filters and whole-home air cleaners sized to your system’s airflow.

FAQs — AC Repair & Installation in Calabasas
Yes. Calabasas sits entirely within a Very High Fire Hazard Severity Zone, so any new installation or replacement must use Chapter 7A-listed ember-resistant vents with specified mesh screening on combustion-air intakes and exhaust terminations. Standard vent caps fail plan-check at LA County Building and Safety. We specify compliant products from the start and include the documentation in our permit package. Call (855) 467-1888 for a free estimate — we’ll walk you through exactly what your home needs.
Calabasas runs 10–15°F hotter than coastal Malibu in summer, and triple-digit heat events stress equipment sized for milder medians. If your unit was installed without a proper Manual J load calculation, or if it’s a single-speed system in a large custom home with vaulted ceilings, it likely can’t move enough capacity during peak demand. We assess your actual cooling load and specify variable-speed or multi-zone equipment if needed. Call (855) 467-1888 for an exact diagnosis.
For most homes in The Oaks and similar Calabasas communities, yes. Floor plans of 3,500–8,000+ square feet with multi-story layouts and vaulted great rooms create uneven cooling loads that single-zone systems can’t balance. A multi-zone variable-refrigerant or zoned-ducted system lets you condition occupied spaces without overcooling guest wings or offices. The upfront cost is higher, but energy savings and comfort improvement are substantial in homes this size. Call (855) 467-1888 and we’ll model the payback for your specific floor plan.
Debris impact on the outdoor condenser coils and electrical disconnect damage are the two failures we see most after Santa Ana events in Calabasas. High winds drive dust, leaves, and embers into coil fins, restricting airflow and causing high-pressure shutdowns. We inspect the full outdoor unit, straighten damaged fins, test electrical connections, and verify refrigerant integrity before restarting. Call (855) 467-1888 — we’ll assess whether it’s repairable or if replacement is the safer path.
We don’t recommend it. Calabasas replacements require Title 24 energy compliance documentation, Chapter 7A vent specifications, and permits pulled through LA County Building and Safety. Owner-installed equipment without proper load calculations often fails inspection, voids manufacturer warranties, and creates safety hazards with refrigerant handling and electrical connections. The money you think you’re saving typically gets spent twice on corrections and delayed occupancy. We’ve taken over DIY installs that stalled at plan-check — it’s faster and less expensive to do it correctly from the start. Call (855) 467-1888 for upfront pricing on a permitted, warranted installation.
