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

We specialize in commercial and mixed-use properties where reliability, energy performance, and indoor air quality matter. Whether you are replacing an aging rooftop package unit, adding capacity for a build-out, or value-engineering a complex design, our engineering-first approach streamlines your RTU project and protects your operations.

Design-build planning that de-risks installation

Every successful rooftop unit project starts with data. We perform on-site assessments, digital load calculations, and duct static pressure checks to select the right AC PRO model, economizer options, and controls. We verify curb dimensions, roof structure, electrical capacity, gas lines (where applicable), and condensate routing before crane day to eliminate surprises.

• Right-sized equipment selection for Glendale’s climate
• Curb adapters engineered to fit existing roof penetrations
• Economizer integration for free cooling and Title 24 compliance
• Controls integration (BACnet or stand-alone) for simple operation
• Airflow balancing and commissioning with documented results

AC PRO rooftop unit solutions for Glendale properties

AC PRO rooftop units offer dependable performance and broad configurability for retail, restaurants, offices, medical suites, and light industrial facilities. We align RTU tonnage, static capability, economizers, and gas/electric configurations with your occupancy patterns and ventilation requirements.
Looking to cut energy costs? We can pair economizers, demand-controlled ventilation, and high-efficiency fan options to reduce kWh without sacrificing comfort.

Our commercial RTU installation process

• Site survey and load calculation
• Scope definition, equipment submittals, and schedule
• Permitting and Title 24 documentation
• Curb adapter design and fabrication (if replacing an existing unit)
• Crane lift planning, rigging, and safety coordination
• Electrical, gas (if applicable), and controls connections
• Duct transitions, economizer setup, and relief/return tuning
• Start-up, airflow balancing, and commissioning report

Indoor air quality and ventilation

We evaluate filtration levels, outside air rates, and relief strategies to meet code and occupant needs. Options include higher MERV filtration, demand-controlled ventilation, and ventilation setpoint optimization to balance IAQ with energy savings.

When to consider an RTU replacement

• Rising energy bills and frequent short-cycling
• Uneven temperatures or poor humidity control
• Repeated compressor or blower failures
• Non-compliant ventilation or economizer faults
• Re-roofing or tenant improvements that change loads

Glendale and Greater Los Angeles coverage

Based in Southern California, we serve Glendale and all of Los Angeles County, plus nearby Orange County, Ventura County, and Western Riverside County. Our team coordinates closely with local building and safety departments and schedules crane operations to minimize street and parking disruptions.

Why engineers matter on rooftop jobs

Commercial rooftops demand more than “like-for-like” swaps. Structural loads, curb geometry, economizer positioning, electrical protections, and airflow balancing all affect performance and lifespan. Our engineering background reduces risk, shortens downtime, and delivers measurable results you can feel on day one.

Upgrades that maximize value

• Curb adapters to fit legacy footprints and avoid roof cuts
• Economizers for free cooling and ventilation control
• Smart thermostats or BAS integration for scheduling and alerts
• Enhanced filtration and coil protection for cleaner air
• Vibration isolation and sound treatments for quiet operation
