Commercial & Industrial Exhaust Systems in Orange | York Service

What We Design, Install, and Service

We provide turnkey commercial and industrial exhaust solutions in Orange—from design and permitting to startup, testing, and long‑term maintenance. Our scope includes:

• Kitchen grease exhaust (UL 762 hoods, ducts, fans) with make‑up air and demand ventilation
• York‑integrated exhaust and ventilation tied to rooftop units and building controls
• Laboratory, R&D, and light industrial process exhaust, fume hoods, and dedicated dilution systems
• Parking garage CO/NO2 exhaust with sensor arrays and variable speed control
• Smoke control and stair pressurization coordination with life‑safety systems
• General ventilation, restroom exhaust, and heat/energy recovery where appropriate
• Retrofits, right‑sizing, and energy optimization for existing facilities

We support centrifugal, axial, and inline fans; ECM/VFD drives; grease containment; fire/suppression interlocks; and airflow monitoring and alarms.

York Equipment Expertise

Our engineers service and integrate exhaust systems with York commercial equipment, including rooftop units (RTUs), air handlers, energy recovery, and VFD‑driven fans. We optimize control sequences so exhaust rates, make‑up air, and space pressurization work in concert with York systems for comfort, code compliance, and energy savings.

• Exhaust and make‑up air interlocks with York RTUs and BAS
• VFD tuning for stable static pressure and quieter operation
• Setpoint strategies for occupancy, cooking load, and IAQ events
• Commissioning and re‑commissioning for verified performance

Note: Our team services York equipment and controls; factory training cited is with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China).

Code, Safety, and Quality Assurance

Your project is engineered to meet and document compliance with NFPA 96 (kitchens), California Mechanical Code, Title 24, ASHRAE guidelines, local fire department requirements, and landlord criteria. We coordinate with fire suppression vendors, electrical trades, and the AHJ to streamline approvals and inspections.

• Stamped drawings and submittals as required
• Grease duct routing, access, clearance, and fireproofing per code
• Demand Control Kitchen Ventilation (DCKV) to reduce energy
• CO/NO2 sensing and alarm protocols for garages
• Airflow Testing, Adjusting, and Balancing (TAB) with final reports

Deliverables include O&M manuals, training, and closeout packages to keep your team confident and compliant.

Design‑Build Workflow

Whether you are retrofitting a restaurant in Old Towne Orange or expanding a manufacturing line, our design‑build process reduces risk, change orders, and downtime.

• Discovery: Site walk, load profiling, and code review
• Engineering: Airflow modeling, equipment selection, and controls strategy
• Permitting: Submittals and AHJ coordination
• Construction: Safety‑first installation with dust, odor, and noise mitigation
• Startup: Controls programming, interlocks, and sequence validation
• Commissioning: TAB, documentation, and operator training

We aim for first‑inspection approvals and long‑term reliability.

Preventive Maintenance and 24/7 Repair

Exhaust systems live hard. Grease, particulates, and high duty cycles degrade performance. Our plans protect uptime and safety while cutting energy costs.

• Fan, belt, bearing, and VFD inspections with trend analysis
• Filter and grease containment service; hood and duct cleaning coordination
• Airflow verification and setpoint optimization by season and load
• Emergency repair, rapid parts sourcing, and temporary ventilation options

We service mixed fleets and keep York integrations tuned for stable pressure and airflow across operating conditions.
