Fast, Reliable Emergency & Commercial HVAC Across West Hills
When your AC quits at 2 PM on a 110°F July afternoon in West Hills, you don’t have time to wait for a dispatcher in another county to find a technician. We answer our own phones, and Marcus Feldman still runs service calls personally. From our base in San Jose, our Emergency & Commercial HVAC team dispatches to West Hills with the specific parts, tools, and local knowledge that 19 years in this trade provides. We’ve worked on the original 1960s ranch systems off Fallbrook Avenue, the hillside custom builds near the Santa Monica Mountain foothills, and the small commercial suites along Victory Boulevard. Call (844) 560-6978 — we’ll talk through what’s happening and get someone moving.
Why Crestview Heating & Air California Is West Hills’s Preferred Emergency & Commercial HVAC Company
West Hills sits in a natural heat trap at the far western end of the San Fernando Valley, where the Simi Hills, Santa Susana Mountains, and Santa Monica Mountains converge and block virtually all marine-layer cooling. That geographic reality shapes every HVAC decision we make here. We’ve learned that a “standard” repair in Woodland Hills often falls short in West Hills, where systems run 25% longer hours and attic ductwork degrades faster than almost anywhere else in the LA metro.
Our 4.8-star average across 250+ customer reviews reflects what happens when an owner-managed operation shows up prepared. Marcus Feldman serves as both Owner and Service Manager, which means the accountability doesn’t stop at a corporate org chart. We’ve earned repeat calls from West Hills homeowners who watched us trace a $600 summer electric bill back to 1970s flex duct melting in a 160°F attic, then fix it properly instead of selling them equipment they didn’t need.
We carry factory-authorized parts for Trane, Lennox, Goodman, and Rheem, among others, so your system, our specialty — even if it’s 40 years old and three brands discontinued the component. Most West Hills calls don’t require a return trip for parts.
Our Emergency & Commercial HVAC Services in West Hills
24/7 Emergency HVAC
Emergency HVAC service is available for when systems fail outside of normal business hours, and in West Hills, those failures cluster around predictable patterns. We’ve responded to midnight compressor seizures on Roscoe Boulevard when rooftop units couldn’t shed heat after triple-digit days. We got an emergency call from a homeowner on Fallbrook Avenue whose 1970s Carrier package unit on the roof had seized in a 108°F heatwave. The original flex duct in the attic had melted at the joints, causing 30% leakage. We replaced the unit with a Trane 16 SEER model and re-sealed all ductwork, dropping their August bill by $180. When you call (844) 560-6978 after hours, you reach someone who can actually dispatch help, not a call center reading a script.

Commercial HVAC
West Hills’s commercial corridor along Victory Boulevard and the light industrial pockets near the 118 freeway depend on reliable climate control for tenant retention and equipment protection. Our commercial HVAC service covers rooftop package units, split systems, and zoned controls for small-to-mid-size properties. We understand that a failed system in a medical suite or server room in 91307 doesn’t allow for a three-day parts hunt. From emergency calls to commercial buildouts, we size equipment for actual West Hills load conditions, not textbook calculations that ignore the 25°F penalty this neighborhood pays compared to coastal LA.

Rooftop Unit Service
Rooftop units on ranch-style homes and low-rise commercial buildings in West Hills overheat and trip compressors due to trapped heat from surrounding mountains and lack of shade. The original Carrier, Lennox, and Trane package units installed during the 1970s and 1980s Canoga Park-era builds are now well past design life, and many have been patched with mismatched components that compound the strain. We evaluate whether a unit can be cost-effectively repaired or if replacement with a properly sized modern system makes financial sense over a 5-year horizon. In West Hills’s thermal environment, oversizing is as common as undersizing, and both cost you.

Chiller Service
While less common in West Hills’s residential stock, chillers serve several commercial and institutional buildings in the 91308 zip code. Our 19 years of HVAC experience includes chiller diagnostics, refrigerant management, and controls integration. Given the particulate loading from Santa Ana wind events through the Santa Susana Pass, chiller condenser coils in West Hills require more frequent maintenance than Valley-floor installations to maintain efficiency and avoid high-pressure shutdowns.

Trusted Brands We Service in West Hills
We service equipment from nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For West Hills customers, this matters because many homes still run original or second-generation equipment from the 1970s and 1980s. We’ve sourced obsolete control boards for early Lennox pulse furnaces, found compatible scroll compressors for aging Rheem package units, and retrofitted Trane systems with modern TXVs when factory originals went extinct. Our parts inventory and supplier relationships mean we don’t tell you “we don’t work on that” — we figure out how to fix it or give you an honest replacement recommendation with real numbers.
Common Emergency & Commercial HVAC Problems We See in West Hills Homes
- Melted flex duct in 150°F attics. Original flex duct from 1960s–70s builds melts or degrades in 150°F+ attics, causing 25–35% leakage and system freeze-ups. Technicians working the 91307 zip code know that sealing those runs is often worth more to comfort and utility bills than replacing the air handler itself, a pitch that resonates strongly with homeowners seeing $400–600 summer SoCalGas/LADWP bills.
- Rooftop compressor failure from heat overload. Rooftop units on ranch-style homes overheat and trip compressors due to trapped heat from surrounding mountains and lack of shade. The thermal mass of a West Hills roof after a 110°F day keeps equipment stressed well into evening hours.
- Rapid filter clogging from Santa Ana wind events. Santa Ana winds force particulate-laden air through filters, causing rapid clogging and blower motor failures in commercial HVAC systems. We recommend upgraded filtration and more frequent change intervals for West Hills properties, particularly those near the Santa Susana Pass corridor.
- Zone imbalance in hillside custom homes. The secondary tier of larger 1980s–1990s custom homes in the hillside pockets closer to the Santa Monica Mountain foothills often has zoned systems that need balancing due to elevation changes. Upper floors overcool while lower levels stagnate, a problem that requires duct modification, not just thermostat adjustment.
Pricing for Emergency & Commercial HVAC in West Hills, CA
We’re upfront about what things cost because surprise invoices destroy trust faster than any equipment failure. A typical AC repair in West Hills runs $150–$650 depending on whether we’re replacing a capacitor or recovering refrigerant and welding a leaking coil. AC installation for a standard replacement in the 91307 or 91308 zip codes generally falls between $3,500–$7,500, with the higher end reflecting duct-sealing work that older West Hills homes almost always need.
Several factors push West Hills jobs toward the upper range of these brackets: attic work in 150°F conditions requires additional safety protocols and time; original duct systems from the Canoga Park era often need partial replacement; and the extreme thermal load means we spec equipment more carefully than in milder climates. We don’t guess — we measure, test, and show you the numbers. Call (844) 560-6978 for a free estimate with no obligation.

FAQs — Emergency & Commercial HVAC in West Hills
Your ducts leak excessively because West Hills’s 150–160°F attic temperatures have degraded the mastic seals and insulation on original 1960s–70s flex duct. The same topographic heat trap that makes your backyard thermometer hit 112°F in July is cooking your ductwork from above. Nearly every pre-1985 system we open in 91307 shows 25–35% leakage. Sealing or replacing those runs often cuts cooling bills by 20–30%. Call (844) 560-6978 for a duct-pressure test — estimates are free.
We prioritize commercial HVAC emergencies in West Hills based on system criticality and safety, with owner-managed dispatch that doesn’t route through a call center. A failed server room or medical suite gets immediate escalation. Our San Jose base allows us to reach the 91307 and 91308 zip codes with technicians who already carry the parts common to West Hills’s dominant equipment brands. Call (844) 560-6978 and describe your situation — we’ll give you a realistic arrival window.
We service all nine major brands for commercial applications in West Hills: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Most West Hills commercial properties run Trane, Lennox, or Carrier package units from the 1980s–2000s, and we maintain active parts channels for all three. Goodman and Rheem appear more frequently in newer retail buildouts. Whatever’s on your roof or in your mechanical room, we’ve worked on it. Call (844) 560-6978 with your model number for specific parts availability.
Replace your 1970s AC if repair costs exceed 40% of replacement value and your summer electric bills top $400, which is common in West Hills given the extreme run hours. Original equipment from the Canoga Park era typically operates at 6–8 SEER versus 16 SEER for modern replacements, and the degraded ductwork those systems connect to wastes another 25–35% of whatever cooling they produce. We run actual load calculations for West Hills’s thermal environment, not rule-of-thumb sizing. Call (844) 560-6978 and we’ll compare 5-year ownership costs honestly.
Santa Ana winds force particulate-laden air through your HVAC filters at accelerated rates, causing rapid clogging, reduced airflow, and eventual blower motor strain or failure. The same topographic funnel that traps heat in West Hills also channels these wind events through the Santa Susana Pass corridor. We recommend checking filters monthly during wind season and upgrading to MERV 11 or higher if your system can handle the static pressure. Commercial properties should consider pre-filters for rooftop units. Call (844) 560-6978 to schedule a filter assessment with your next tune-up.
