Trusted Emergency & Commercial HVAC for California Homeowners
When your HVAC system fails at 2 a.m. or your commercial building’s rooftop unit quits during a heatwave, you need an owner who answers the phone, not a dispatch center reading from a script. At Crestview Heating & Air California, Marcus Feldman handles both ownership and service management personally, bringing nearly two decades of hands-on HVAC experience to every emergency call and commercial project across California. We’ve built a 4.8-star average across 250+ customer reviews by showing up when we say we will, diagnosing accurately the first time, and repairing systems other companies won’t touch. Whether it’s a failed chiller at a retail plaza in San Marcos or a midnight furnace outage in a La Puente home, we’re equipped to respond. Call us at (844) 560-6978 for emergency service or to schedule commercial maintenance.
What Our Emergency & Commercial HVAC Service Includes
24/7 Emergency HVAC
HVAC failures don’t follow business hours. Our 24/7 Emergency HVAC line connects you directly to our team for after-hours breakdowns, from compressor failures on sweltering August nights to heat exchanger cracks during January cold snaps in California. Marcus Feldman still takes emergency calls personally when needed, and we stock common parts for Rheem, York, Daikin, Bryant, and other major brands so we can often complete repairs in a single visit rather than ordering components and making you wait.

Commercial HVAC
Small-to-mid-size commercial properties in California need different expertise than residential systems. We’ve serviced office suites in Fairfield, retail spaces in Suisun, and light industrial facilities throughout the region, handling everything from multi-zone controls to economizer troubleshooting. Our factory training across nine major brands means we won’t tell you to call someone else because we “don’t work on that system.”

Rooftop Unit (RTU) Service
California’s commercial buildings rely heavily on packaged rooftop units, which take constant punishment from sun exposure and seasonal temperature swings. We perform full RTU diagnostics, including refrigerant pressure testing, belt and bearing inspection, and economizer calibration. In Plumas Lake and West Covina, we’ve found that neglected RTU maintenance often leads to compressor failures that could have been prevented with timely belt replacement or coil cleaning.

Chiller Service
Chillers serve critical cooling loads for medical offices, data rooms, and larger commercial facilities across California. Our team handles chiller diagnostics, refrigerant management, and controls troubleshooting for both air-cooled and water-cooled systems. We document baseline performance metrics during every Chiller Service call so we can spot efficiency degradation before it becomes a full shutdown.

Annual Maintenance
Preventive maintenance is where commercial operators save real money. Our Annual Maintenance agreements for California businesses include seasonal filter changes, coil cleaning, electrical connection tightening, and full system performance documentation. For residential customers, annual tune-ups catch worn capacitors, dirty burners, and refrigerant leaks before they cause emergency calls.

HVAC Inspection
Property managers in Valinda, South San Jose Hills, and Hacienda Heights use our inspection reports for lease turnovers, pre-purchase evaluations, and insurance documentation. We deliver written assessments with photo documentation, estimated remaining equipment life, and prioritized repair recommendations. This transparency helps California property owners budget accurately rather than facing surprise replacement costs.

Brands We Service for Emergency & Commercial HVAC
We’ve spent 19 years working on virtually every HVAC brand installed in California homes and businesses. Our factory-trained technicians service Carrier systems with their proprietary communicating controls, Trane units with their Climatuff compressor technology, Lennox equipment with variable-capacity modulation, Goodman systems common in new construction, and Rheem units we’ve repaired by the hundreds across the state. We stock OEM and quality aftermarket parts for all five, which means faster repairs and fewer return trips.
We also maintain deep familiarity with York commercial rooftop units, Daikin mini split and VRF systems increasingly popular in California’s accessory dwelling units, Bryant Evolution series controls, and American Standard AccuComfort variable-speed systems. Whether you have a 20-year-old Rheem furnace in Avocado Heights or a new Daikin VRV system in a San Jose commercial buildout, your system is our specialty. We don’t turn jobs away because of brand unfamiliarity.
Signs You Need Emergency & Commercial HVAC Right Now
- Complete system shutdown with no power response. If your thermostat is active but the HVAC unit won’t cycle on at all, you may have a failed contactor, blown fuse, or seized compressor. In California’s peak summer heat, this becomes an emergency within hours for vulnerable occupants or temperature-sensitive inventory. Call (844) 560-6978 immediately.
- Unusual burning or electrical odors from vents or equipment. Any acrid smell from your HVAC system indicates potential electrical overheating, motor failure, or heat exchanger damage. We’ve responded to calls in West Puente Valley where delayed action turned a $200 capacitor replacement into a full furnace replacement after wiring damage spread.
- Loud grinding, screeching, or banging noises. These mechanical warnings typically mean failing bearings, loose blower wheels, or compressor damage. Continuing to run the system often destroys additional components. Our emergency diagnostics include vibration analysis to pinpoint the exact source before secondary damage occurs.
- Refrigerant leaks with visible ice formation or hissing. Ice on refrigerant lines or outdoor coils signals low charge, which strains compressors and can cause complete failure. California’s extended cooling season means refrigerant leaks cost more in energy waste and eventual compressor damage the longer they’re ignored.
- Carbon monoxide detector activation near gas heating equipment. This requires immediate evacuation and emergency service. We inspect heat exchangers with borescope cameras and combustion analyzers to identify cracks or rollout conditions. Never ignore CO alarms or attempt to restart a flagged system yourself.
Our Emergency & Commercial HVAC Process — Step by Step
- 1
Direct contact and dispatch. When you call (844) 560-6978, you reach our team directly, not a third-party answering service. We gather system details, failure symptoms, and property access information. For commercial accounts in California, we maintain after-hours contact protocols so authorized personnel are notified appropriately.
- 2
On-site diagnostic assessment. Marcus Feldman or a senior technician arrives with digital manifold gauges, combustion analyzers, electrical multimeters, and borescope inspection equipment. We test every component systematically rather than guessing at parts to replace. This diagnostic rigor comes from 19 years of pattern recognition across thousands of California systems.
- 3
Transparent repair or replacement recommendation. We explain findings in plain language, show you diagnostic readings, and provide written options with exact pricing. For commercial clients, we include downtime estimates and phased repair alternatives when full immediate replacement isn’t feasible.
- 4
Authorized repair with quality parts. We use OEM or equivalent-grade components, never generic substitutions that compromise reliability. Our vans carry common parts for Rheem, York, Daikin, Bryant, and other major brands to complete most repairs in one visit.
- 5
Performance verification and documentation. After repair, we run full system cycles, measure supply and return temperatures, and verify proper operation under load. Commercial clients receive service reports with before/after performance data for their maintenance records. Residential customers get our workmanship guarantee and clear guidance on any follow-up needs.
How Much Does Emergency & Commercial HVAC Cost in California?
Emergency and commercial HVAC service in California follows clear pricing structures based on the work required. A typical emergency repair call runs $150–$650 for AC issues and $150–$700 for furnace problems, depending on which components have failed. Commercial rooftop unit repairs often fall in the mid-to-upper range due to higher refrigerant volumes and specialized access requirements. Annual maintenance agreements for California commercial properties typically range from $80–$200 per visit per unit, with multi-unit discounts available.
Several factors affect your final cost. After-hours emergency rates apply when systems fail outside normal business hours, though we never charge simply to show up and diagnose. The age and brand of your equipment matters, older Bryant or York systems may need harder-to-source parts, while newer Daikin mini splits often have warranty coverage that reduces out-of-pocket expense. Accessibility also affects pricing, rooftop units in West Covina commercial plazas or cramped mechanical rooms in older Fairfield buildings require additional labor time.
To avoid overpaying, get a written estimate before authorizing work, ask whether quoted prices include parts and labor or just labor, and verify the technician has actually diagnosed the root cause rather than replacing parts speculatively. Our estimates are always free, with no obligation to proceed. We itemize parts, labor, and any after-hours premiums so California property managers can compare apples-to-apples.
