Fast, Reliable Emergency & Commercial HVAC Across Agoura Hills
When your AC fails during a Santa Ana wind event or your commercial rooftop unit quits on a Friday afternoon, you need a contractor who knows Agoura Hills — not a dispatcher reading from a script. Stonegate Heating & Air California dispatches our Emergency & Commercial HVAC team to Agoura Hills with the equipment and local knowledge to handle both 1970s tract homes on Kanan Road and post-Woolsey Fire rebuilds in the 91301 hills. We’re owner-supervised by Jason Trent, 16 years in business, nearly 500 reviews at 4.7 stars. Call (855) 467-1888 for emergency response or to schedule a commercial inspection.
Why Stonegate Heating & Air California Is Agoura Hills’s Preferred Emergency & Commercial HVAC Company
Our reputation in Agoura Hills was built job by job, not through marketing campaigns. Jason Trent supervises every project as Field Supervisor, which means company leadership steps out of the truck at your property — not a rotating cast of subcontractors you’ve never met. That accountability shows in our numbers: 499 verified reviews averaging 4.7 stars across platforms, earned over 16 years of continuous California operation.
We’ve worked the full spectrum of Agoura Hills housing. The 1970s–1990s subdivisions near Reyes Adobe Road with original ductwork baking in 140°F attics. The hillside rebuilds off Cornell Road built to 2019 Title 24 codes with heat-pump-ready electrical and MERV-13 filtration. The commercial suites along Agoura Road with aging package units. This range matters because Agoura Hills isn’t a generic suburb — it’s a city where one ZIP code can contain three decades of radically different building standards.
Response time to Agoura Hills runs same-day for emergency calls placed before 2 PM, and our stocked trucks carry parts for Carrier, Trane, Lennox, and Goodman — the four brands we see most often in this market. No waiting three days for a coil that should have been on the shelf.
Our Emergency & Commercial HVAC Services in Agoura Hills
24/7 Emergency HVAC
Agoura Hills summer highs hit the mid-90s routinely, and Santa Ana pushes past 100°F with humidity in single digits. Your AC wasn’t designed for that loading. When it fails at 9 PM on a 102° night, we answer. Our emergency line routes directly to dispatch, not a voicemail tree. We carry replacement compressors, capacitors, and contactors for the nine brands we service, including the Goodman and Lennox units common in local tract homes.
Commercial HVAC
Agoura Hills’s commercial base runs from professional offices along Agoura Road to light industrial near the 101 corridor. These systems see different failure patterns than residential: economizer dampers seize from dust, VAV boxes lose calibration, and rooftop units suffer from deferred maintenance during ownership transitions. Jason Trent personally reviews commercial proposals because the stakes of a miscalculated load calculation or missed duct leakage are higher here — lost revenue, violated leases, code violations on tenant improvements.
Rooftop Unit Service
Agoura Hills’s commercial rooftops take a beating. Summer thermal cycling cracks condenser coils. Santa Ana winds drive debris into intake hoods. Many units installed in the 2000s are hitting end-of-life simultaneously, creating replacement backlogs. We service Carrier, Trane, and York rooftop units with factory-trained protocols, and we stock common heat exchanger and control board replacements to minimize downtime for your tenants.
Chiller Service
While smaller than downtown LA’s chiller density, Agoura Hills has critical chiller loads: medical offices, data-adjacent commercial, and some multi-tenant properties with central plants. Chiller failures cascade fast — one down compressor can spike operating costs 40% on the remaining machines. Our technicians carry EPA Section 608 certification for refrigerant handling and perform oil analysis, tube inspection, and control calibration on Trane, Carrier, and York chillers serving Agoura Hills properties.
HVAC Inspection
This is where our Agoura Hills specificity matters most. We arrived at a hillside home on Cornell Road in 91301 for a routine furnace tune-up and discovered the evaporator coil was caked with black soot from the Woolsey Fire’s smoke infiltration. Our team replaced the coil with a Lennox model and thoroughly cleaned the ductwork, restoring airflow and indoor air quality for the homeowner. That pattern — soot contamination in homes that physically survived the 2018 fire — is something we check for on every inspection in fire-affected neighborhoods. Many owners never had post-fire duct testing. We find the damage they didn’t know existed.

Trusted Brands We Service in Agoura Hills
We’re certified to work on nine leading HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Agoura Hills, we see Carrier and Trane most frequently in post-2019 rebuilds — builders spec’d them for Title 24 compliance. Goodman and Lennox dominate the 1980s–1990s residential stock. Our trucks carry common parts for all four, which means same-day repair probability is higher than contractors who special-order everything. For commercial clients, that parts availability translates directly to uptime. No “we don’t service that brand” dead ends. Whatever equipment is on your roof or in your basement, we’ve likely repaired its exact failure mode before.
Common Emergency & Commercial HVAC Problems We See in Agoura Hills Homes
- Smoke-contaminated ductwork and coils from the 2018 Woolsey Fire. Homes that survived the fire often pulled smoke particulates into the plenum through return air pathways. We regularly find soot-coated evaporator coils and degraded duct liners in 91301 hillside properties — contamination that standard tune-ups miss without specific inspection protocols.
- Failed duct seals in 1970s–1990s tract homes. Original duct systems with minimal insulation run through attics that hit 140°F in August. The mastic and tape degrade. Conditioned air leaks into unconditioned space before reaching rooms. Your thermostat reads 78° but your bedroom never gets there.
- AC compressor failure during Santa Ana events. Single-digit humidity and 100°F+ temperatures push discharge pressures beyond design limits. Capacitors fail under thermal stress. Contactors weld closed. The system was technically “working” until the load exceeded its degraded capacity.
- Heat pump incompatibility in post-fire rebuilds. Title 24 2019/2022 requires heat-pump-ready infrastructure, but some rebuilds used minimum-compliance electrical panels that struggle with cold-climate heat pump amp draws. We verify panel capacity and breaker sizing before recommending equipment swaps.
Pricing for Emergency & Commercial HVAC in Agoura Hills, CA
Agoura Hills pricing aligns with broader Ventura County HVAC markets, with modest premiums for hillside access and post-fire remediation complexity. Here’s what typical residential and light commercial work runs:

FAQs — Emergency & Commercial HVAC in Agoura Hills
A typical residential duct cleaning and coil replacement for Woolsey Fire smoke damage takes one to two days, depending on system size and contamination depth. We seal registers, use negative-air HEPA extraction, and replace porous duct liner that has absorbed smoke particulates — surface cleaning alone won’t remove embedded soot. Call (855) 467-1888 to schedule an inspection if your home survived the 2018 fire and hasn’t had post-fire duct testing.
Yes, if your rebuild permit was issued after January 1, 2020, California’s Title 24 standards require heat-pump-compatible infrastructure or an approved exception. We verify your electrical panel ampacity, breaker configuration, and duct leakage compliance before specifying equipment — some 2019–2021 rebuilds used marginal electrical sizing that needs upgrading for cold-climate heat pump operation. Jason Trent reviews these assessments personally.
We service all nine major commercial HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Agoura Hills commercial properties, we most commonly maintain Carrier and Trane rooftop units, with York chillers appearing in some multi-tenant buildings. Our parts inventory covers the control boards, heat exchangers, and economizer components that fail most often in local climate conditions.
If your home survived the 2018 Woolsey Fire and you have not had a post-fire duct inspection, schedule one immediately — we are still finding active contamination six years later. After initial remediation, annual inspection is sufficient unless you notice persistent odors, reduced airflow, or respiratory symptoms. Agoura Hills’s Very High Fire Hazard Severity Zone designation means air quality events recur; MERV-13 filtration and sealed duct systems provide measurable protection.
Evaporator coil replacement in Agoura Hills typically runs $800–$2,400 including refrigerant recovery, coil, and labor, with the wide range reflecting system size and access difficulty. Post-Woolsey Fire jobs often require additional duct cleaning ($400–$1,200) and sometimes plenum replacement if smoke penetrated the air handler cabinet. We diagnose with borescope inspection before quoting — no guesswork on contamination extent. Call (855) 467-1888 for a free estimate.
