Commercial Rooftop Unit (RTU) Installation in Pasadena — AC PRO

Why AC PRO RTUs for Pasadena commercial buildings

AC PRO rooftop units are a strong fit for Southern California’s climate, offering dependable performance, wide parts availability, and configurations for gas/electric or heat pump packages. In Pasadena’s mixed cooling and heating seasons, a properly selected AC PRO RTU can reduce energy use, stabilize comfort, and support better indoor air quality when paired with right‑sized ventilation and filtration.

• Efficient options with economizers, demand‑controlled ventilation, and variable fan operation
• Reliable components and local parts support to minimize downtime
• Flexible tonnage, airflow, and curb sizes to fit replacements or new builds
• Compatible with modern thermostats, BMS/BAS controls, and zoning strategies

We match your business needs—quiet operation, steady temperatures, and low operating cost—to the right AC PRO RTU configuration and controls strategy.

Our engineering‑first installation process

• Discovery & assessment: Site survey, existing RTU evaluation, electrical and gas verification, duct static review, and rooftop access planning.
• Design & permitting: Load calculations, equipment sizing, curb adaptor design, Title 24 documentation, and permit coordination.
• Logistics & safety: Crane planning and traffic control, OSHA safety compliance, seismic requirements, and delivery timing to protect your operations.
• Installation & controls: Rigging, curb setting, duct transitions, gas/electric hookups, condensate routing, economizer setup, smoke detector integration, and BAS tie‑in.
• Commissioning & turnover: Airflow balancing, refrigerant verification, controls programming, acceptance testing coordination, and owner training.

Every step is documented and quality‑checked so your AC PRO rooftop unit delivers the specified performance on day one and remains serviceable for years.

What we handle on your behalf

• Crane lifts, rigging plans, and rooftop access coordination with building management
• Seismic curbs, curb adaptors, and sheet‑metal transitions tailored to your roof
• Electrical disconnects, gas piping, condensate management, and code upgrades
• Economizers, CO2 sensors for demand ventilation, and MERV 13+ filtration options
• Smoke detector wiring, alarm interlocks, and BAS integration
• Title 24 compliance documentation and required acceptance testing coordination

Our mission is healthy indoor air for healthy lives. That means clean filtration, balanced ventilation, and precise commissioning—so occupants feel better and equipment lasts longer.

Healthy air and lower lifecycle cost

We design for both comfort and economics. By optimizing outside air with economizers, specifying higher‑efficiency fan configurations, and ensuring ducts are sealed and balanced, we reduce energy waste without sacrificing indoor air quality. For owners targeting sustainability or electrification, we can evaluate heat pump RTU options and controls strategies that support lower carbon and utility savings.

If your Pasadena property has varying occupancy—retail rushes, classroom schedules, or office hybrids—demand‑controlled ventilation paired with AC PRO RTUs can maintain fresh air while trimming unnecessary runtime.

Ideal for many Pasadena properties

• Office buildings and coworking spaces
• Retail stores and shopping centers
• Restaurants and food service (with appropriate make‑up air coordination)
• Medical and dental clinics
• Schools, houses of worship, and community centers
• Light industrial, warehouses, and maker spaces
• Multifamily common areas and mixed‑use tenant improvements

We tailor each AC PRO RTU installation to your building’s architecture, usage patterns, and budget—whether it’s a one‑for‑one replacement, a capacity right‑size, or a full design‑build upgrade.
