Why Stonegate Heating & Air California Is Calabasas’s Preferred Heat Pump & Mini Split Company
We’ve built our reputation over 16 years on one principle: the owner stays accountable on every job. Jason Trent doesn’t delegate from an office. He serves as Field Supervisor, which means he’s physically present on installations, reviewing load calculations, checking refrigerant charges, and verifying that every Calabasas permit submission meets L.A. County’s exacting standards. That matters here more than most places.
Calabasas homeowners research before they call, and they should. Our 499 verified reviews averaging 4.7 stars reflect real jobs on real equipment, not cherry-picked testimonials. We’ve earned trust in communities like The Oaks and along Park Granada and Las Virgenes Road by showing up with factory-trained technicians who work across nine major brands, not two or three.
Our familiarity with Calabasas runs deep. We know the difference between a 1989 original build with single-stage equipment and a 2022 post-Woolsey rebuild with communicating inverter systems. We know that L.A. County plan checkers scrutinize Chapter 7A vent details that pass without comment in Agoura Hills. That local fluency saves our Calabasas customers permit delays and failed inspections.
From a single-room mini split to a full multi-zone heat pump system, we scope the job correctly the first time. No “we’ll figure it out on install day.” Jason supervises every project.
Our Heat Pump & Mini Split Services in Calabasas
Heat Pump Repair
Calabasas heat pumps take a beating. Summer days in this inland valley regularly hit triple digits, 10–15°F hotter than Malibu just over the Santa Monica Mountains, while winter nights drop to the low 40s. That wide swing stresses compressors, reversing valves, and defrost controls. We see ember intrusion through non-compliant vent caps during Santa Ana wind events, causing compressor shutdowns or worse. Our repairs address the immediate failure and the underlying cause, whether it’s a refrigerant leak in a Carrier unit or a failed board in a Trane system. We stock parts for nine brands, so we’re not ordering and waiting while your home swelters.

Heat Pump Installation
New heat pump installation in Calabasas requires precise Manual J load calculations, especially in the 3,500–8,000+ sq ft custom homes that dominate this market. Vaulted great rooms, multi-story layouts, and open floor plans common in gated communities like The Oaks demand equipment sized for genuine extremes, not coastal medians. Undersized units short-cycle. Oversized units dehumidify poorly and waste energy. We calculate correctly, specify variable-capacity or two-stage equipment where appropriate, and ensure every combustion-air intake and exhaust termination uses Chapter 7A-compliant, mesh-screened vent products. Generic vent caps don’t pass L.A. County plan check here. Period.

Mini Split Install
Mini splits solve specific problems in Calabasas homes: room additions, converted garages, guest houses, or zones where extending ductwork is impractical. We install single-zone and multi-zone systems from Daikin, Carrier, and other leading brands, with line-set routing that respects custom finishes and architectural details. A recent job in The Oaks linked a multi-zone Daikin system to the homeowner’s Crestron panel for full smart-home integration. We handled the Chapter 7A vent caps on exterior penetrations and passed plan check on first submission. That’s the difference owner supervision makes.

Mini Split Repair
Calabasas mini split repairs often trace to installation errors by less experienced crews: improper flare connections causing refrigerant leaks, condensate drains routed without proper slope, or outdoor units placed where Santa Ana winds blast debris into coils. We diagnose correctly, repair with factory-spec parts, and verify operation across all zones before we leave. Our Heat Pump & Mini Split team carries the tools and refrigerants for modern R-410A and newer R-32 systems.

Common Heat Pump & Mini Split Problems We See in Calabasas Homes
- Ember intrusion through non-compliant vent caps. Calabasas sits entirely within a Very High Fire Hazard Severity Zone. During Santa Ana wind events, embers enter standard vent caps and damage outdoor units or trigger safety shutdowns. We replace with Chapter 7A-listed mesh-screened vents that satisfy L.A. County plan check.
- Improper sizing in vaulted custom homes. The 3,500–8,000+ sq ft homes typical of Calabasas, with their soaring great rooms and open plans, routinely get undersized equipment from contractors who guess rather than calculate. Short-cycling, hot spots, and premature compressor failure follow. We run full Manual J loads.
- Mismatched post-Woolsey ductwork and older heat pumps. Rebuilds after the November 2018 Woolsey Fire feature modern high-efficiency ductwork designed for variable-speed equipment. Pair that with an existing single-speed heat pump and you get refrigerant pressure errors, reduced SEER2 performance, and comfort complaints. We identify the mismatch and specify correct equipment.
- Smart-home integration failures. Calabasas homeowners expect Crestron, Control4, or native app control. We commission integrations properly, not as afterthoughts, ensuring thermostat commands actually reach the equipment.

FAQs — Heat Pump & Mini Split in Calabasas
Yes, all Calabasas installations must comply with CBC Chapter 7A ember-resistant vent requirements for combustion-air intakes and exhaust terminations, enforced by L.A. County Building and Safety on unincorporated parcels. We specify listed mesh-screened vent products on every plan submission and have never had a permit rejected for venting non-compliance. Call (855) 467-1888 to confirm your property’s jurisdiction and requirements.
Undersizing is the usual culprit, driven by contractors using coastal load assumptions instead of Calabasas’s actual triple-digit peak demand. Vaulted ceilings and open floor plans amplify the problem. We run proper Manual J calculations and specify equipment with sufficient capacity and airflow for your specific home. Call (855) 467-1888 if your current system can’t keep up.
Yes, most modern heat pumps and mini splits offer integration with Crestron, Control4, and major smart-home platforms, though proper commissioning is critical. We recently linked a Daikin multi-zone system to a Crestron panel in The Oaks, with Chapter 7A venting, passing plan check on first submission. Call (855) 467-1888 to discuss your specific platform.
Variable-speed or fully communicating inverter-driven systems pair best with the high-efficiency ductwork installed in post-2018 rebuilds, delivering the SEER2 performance the ductwork was designed for. Single-speed equipment mismatched to modern ductwork causes pressure errors and poor efficiency. We assess your duct system and specify accordingly. Call (855) 467-1888 for a load calculation and recommendation.
Santa Ana winds spike outdoor temperatures rapidly, increase cooling load, and carry embers and debris that clog coils and damage non-compliant vents. Low humidity during these events also reduces natural dehumidification, making proper system sizing and air filtration more important. We specify equipment rated for your home’s actual peak load and install Chapter 7A-compliant venting to protect against ember intrusion. Call (855) 467-1888 to schedule a pre-wind-season tune-up.
