Commercial & Industrial Plant Cooling in Pasadena

Engineering-First Commercial HVAC for Pasadena Facilities

At #1 AC Guys, cooling is engineered — not guessed. As a fourth-generation family of engineers with 80+ years of engineering experience, we design and deliver commercial HVAC and industrial plant cooling built for reliability, efficiency, and healthier indoor air. Our mission is simple: healthy air for a healthy life, even in demanding industrial settings.

From Pasadena’s historic manufacturing buildings to modern research spaces, we integrate systems that stabilize temperatures, safeguard processes, and meet strict local codes and sustainability goals.

Industrial Plant Cooling Capabilities

• Process cooling for production lines, packaging, and equipment rooms
• High-capacity rooftop and split systems for warehouses and distribution
• VRF/VRV solutions for multi-zone buildings with advanced controls
• Dedicated outdoor air systems (DOAS) and balanced ventilation for cleaner air
• Filtration and IAQ upgrades to reduce particulates and support occupant health
• Redundancy and staged capacity to protect uptime during peak loads
• Energy optimization through controls tuning, heat recovery, and commissioning

We tailor each project to your load profile, operating hours, utilities, and ROI targets — so your plant stays productive without overpaying on energy.

Our Process: From Assessment to Commissioning

• Site walk and data gathering: envelope, internal loads, existing equipment, and airflow.
• Engineering analysis: detailed load calculations, ventilation modeling, and controls strategy.
• Design and scope: options with lifecycle cost, efficiency tiers, and phasing to minimize downtime.
• Procurement: we can source equipment through AC PRO for fast regional availability.
• Installation: coordinated with your production schedule, safety-first and permit-ready.
• Startup and commissioning: verification of airflow, refrigerant charge, controls, and documentation.
• Lifecycle support: preventive maintenance, performance tuning, and upgrades as your facility grows.

Technologies and Training

Our team is factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This training strengthens our work with VRF/mini-split networks, advanced controls, and efficient heat pump designs. For fast, local availability, we can supply equipment through AC PRO, helping keep Pasadena projects on schedule and on budget.

Whether your solution calls for high-tonnage packaged units, multi-zone VRF, or ventilation upgrades to improve indoor air quality, we integrate the right components into a cohesive, easy-to-service system.

Compliance, Safety, and Documentation

We deliver code-compliant projects aligned with California Title 24, local Pasadena permitting requirements, and ASHRAE best practices. Our crews follow rigorous safety protocols and provide complete documentation — submittals, cut sheets, commissioning reports, and O&M manuals — so your facility passes inspections and your team can maintain performance with confidence.

Designed for Healthier Air

Healthy air isn’t just for homes. In commercial and industrial spaces, cleaner air supports employee well-being and process quality. We implement proper ventilation rates, filtration upgrades, and smart controls that maintain air changes and pressure balances while minimizing energy waste.

Service Area and Rapid Response

Based in Los Angeles, we proudly serve Pasadena and all of Los Angeles County — with projects also spanning nearby Orange County, Ventura County, and Western Riverside County. Our proximity and AC PRO’s regional inventory help reduce lead times and accelerate installs.

Results You Can Measure

• Stable process temperatures and tighter tolerances
• Lower energy intensity per unit produced
• Improved indoor air quality and comfort
• Reduced unplanned downtime and maintenance surprises
• Clear documentation and training for your staff

When uptime matters, you need a partner who thinks like an engineer and delivers like a contractor. That’s what #1 AC Guys brings to every Pasadena engagement: disciplined analysis, proven field execution, and support that lasts for the life of your system.
