Industrial & Manufacturing HVAC
Industrial HVAC for Facilities Where Production Doesn’t Stop
Your HVAC system isn’t just climate control — it’s part of your production infrastructure. Process cooling keeps manufacturing lines running. Ventilation keeps workers safe and OSHA compliant. Temperature control protects inventory, equipment, and product quality.
Circulating Air has served industrial and manufacturing facilities across Los Angeles for 60 years. We build, maintain, and repair HVAC systems designed for environments that general commercial contractors aren’t equipped to handle.

Industry Requirements
What Industrial Facilities Demand from HVAC
Industrial HVAC operates in conditions that push systems harder, expose them to more contaminants, and leave less margin for downtime. The requirements go well beyond comfort cooling.
Process cooling
Manufacturing equipment generates significant heat loads. CNC machines, injection molding, printing presses, and server farms all require dedicated cooling that operates independently of the building’s comfort system. Losing process cooling means stopping production.
Ventilation and air quality
Cal/OSHA requires adequate ventilation for worker safety — especially in facilities that produce dust, fumes, or volatile organic compounds. Exhaust systems, make-up air units, and filtration must be properly designed and maintained.
Extreme environments
Industrial HVAC systems face conditions that destroy residential and light commercial equipment: high ambient temperatures, corrosive atmospheres, heavy particulate loads, and vibration. Equipment selection and maintenance have to account for these realities.
Uptime requirements
Production downtime costs money by the hour. HVAC failures that shut down a manufacturing line or force a warehouse to close carry direct financial consequences that compound rapidly.
Code and safety compliance
Cal/OSHA ventilation requirements, SCAQMD air quality regulations, Title 24 energy code, and industry-specific standards all impose constraints on industrial HVAC design and operation.
What We Do
Industrial HVAC Services Across Los Angeles — Manufacturing, Warehousing, and Process Cooling
When process cooling drops, the line stops — and HVAC stops being a building system and becomes a production cost measured by the hour. We engineer industrial HVAC for Los Angeles manufacturers, warehouses, and distribution centers: dedicated process cooling, Cal/OSHA-compliant ventilation, large-tonnage rooftop service, and 24/7 emergency dispatch for the equipment most contractors don’t stock parts for.
For facilities that need ongoing coverage, we offer service agreements with priority dispatch and maintenance schedules designed around production calendars.
Process cooling
Design, installation, and maintenance of dedicated cooling systems for manufacturing equipment. Chilled water systems, glycol loops, spot cooling, and equipment-specific thermal management. We size and configure systems based on actual heat load calculations, not rules of thumb.
Industrial ventilation
Exhaust systems, make-up air units, dust collection integration, and fume extraction. We design ventilation solutions that meet Cal/OSHA requirements and maintain worker safety in challenging environments.
Warehouse and distribution
Large-volume HVAC for warehouses, distribution centers, and fulfillment operations. Evaporative cooling, high-volume low-speed fans, stratification management, and dock door air curtains — solutions matched to the specific thermal dynamics of large open spaces.
Rooftop unit service
Industrial facilities often depend on large rooftop units. We maintain, repair, and replace RTUs across all major brands — Trane, Carrier, Lennox, York, and others — including units in the 25–100+ ton range common in industrial applications.
Emergency repair and 24/7 service
When a chiller serving your production line goes down at midnight, you need a contractor who answers and who can fix it. Our 24/7 dispatch deploys technicians with industrial experience and the parts inventory to handle critical repairs fast. See emergency service →
Why Circulating Air
Why Circulating Air for Industrial HVAC
60 years in Los Angeles, including decades in the manufacturing plants, warehouses, and distribution centers where HVAC is production infrastructure and downtime is measured by the hour. We stock parts for the large-tonnage rooftop units, chilled-water plants, and process-cooling systems most contractors have to order — and we schedule around your production calendar, working nights, weekends, and shutdowns. When a chiller serving your line goes down at 2 a.m., we’re the crew that answers and the crew that can fix it.

What to Expect
How We Work with Industrial Facilities
1
Facility survey
We assess your mechanical systems, review your process cooling requirements, evaluate ventilation against Cal/OSHA standards, and identify any equipment nearing end of life.
2
Scope and solution design
Based on the survey, we develop a service plan that addresses your facility’s specific needs — whether that’s a maintenance program, a ventilation redesign, or a phased equipment replacement plan.
3
Production-aware scheduling
All work is scheduled around your production calendar. We coordinate with plant operations to minimize downtime and stage work so critical systems stay online during service.
4
Execution and documentation
Technicians perform work to spec and document everything. You get maintenance records, equipment condition reports, and compliance documentation for your safety files.
5
Ongoing support
Most industrial clients transition to a service agreement for continuous coverage. Scheduled maintenance, priority emergency dispatch, and equipment lifecycle tracking — all managed by a dedicated account contact.
See our service agreement options for details on ongoing industrial HVAC support.
Industrial HVAC — Common Questions
What plant engineers, facility managers, and operations directors ask when production can’t afford HVAC downtime.
Do you handle process cooling for manufacturing equipment?
Yes. We design, install, and maintain process cooling systems for manufacturing environments including chilled water systems, glycol loops, and dedicated equipment cooling. We size systems based on actual heat load calculations from your specific equipment, not generic estimates.
Can you work in hazardous or specialized industrial environments?
We have experience working in environments with heavy dust loads, chemical exposure, extreme heat, and other conditions common in industrial facilities. Our technicians follow site-specific safety protocols and have the training to work in environments that require PPE, lockout/tagout, and confined space procedures.
What size equipment do you service?
We service and install commercial and industrial HVAC equipment from small split systems through large-tonnage rooftop units, chilled water plants, and central plant equipment. For major equipment replacements, see our system replacement services.
How do you schedule maintenance without disrupting production?
All maintenance is scheduled in coordination with your plant operations team. We work nights, weekends, and shutdown periods to align HVAC service with your production calendar. For facilities that run 24/7, we stage work to maintain system redundancy throughout.
Do you handle Cal/OSHA ventilation compliance?
We design and maintain ventilation systems that meet Cal/OSHA requirements for industrial workplaces. This includes exhaust systems, make-up air units, and indoor air quality monitoring. We can also assess existing systems against current standards and recommend upgrades where needed.
Can you support multiple facilities across our operation?
Yes. We work with industrial companies that operate multiple facilities in the Los Angeles area. You get consistent service standards, a single account contact, and consolidated maintenance tracking across all locations. See our service agreements for multi-facility support.
