Bosch Commercial Rooftop Unit (RTU) Installation in Pasadena

When your Pasadena facility needs a reliable, efficient rooftop solution, #1 AC Guys delivers Bosch commercial RTU installations with an engineering‑first process. We’re a family business in Southern California for four generations, bringing 80+ years of engineering experience to every project—especially the big and complex ones.

What to expect with our Bosch RTU installation

• Site survey and load calculations to right‑size your rooftop
• Equipment selection to optimize capacity, IEER, and lifecycle cost
• Crane and rigging planning for safe, efficient lifts on busy streets
• Curb adapters or new curbs engineered for fit, drainage, and airflow
• Ductwork corrections for static pressure, leakage, and balance
• Electrical and gas connections, controls wiring, and labeling
• Economizer setup, airflow verification, and sensor calibration
• Seismic anchorage and vibration isolation to California standards
• Startup, commissioning, and documentation for compliance

Your result: a Bosch rooftop unit that starts cleanly, runs efficiently, integrates with your controls, and protects indoor air quality from day one.

Engineering‑first, code‑ready, Pasadena‑proven

Pasadena’s mix of historic structures, tight urban sites, and modern campuses demands careful planning. Our team coordinates traffic control, crane permits, building access, and safety plans to minimize disruption. We verify Title 24 requirements, ventilation rates, duct sealing, and economizer operation so your project passes inspection the first time.

Healthy air is our mission. We design for proper filtration (MERV selection), outside air control, CO2 demand control ventilation, and pressurization to reduce pollutants and odors. That means better comfort and better productivity for your occupants.

Why Bosch RTUs for commercial roofs

• Energy‑focused performance that can cut utility costs
• Reliable operation with thoughtful service access
• Flexible controls with BMS integration options
• Economizer and ventilation capabilities for compliance

We pair Bosch rooftops with smart control strategies—scheduling, staging, and economizer logic—to reduce peak loads without sacrificing comfort.

Our team and training

As a 4th‑generation engineering family, we bring hard‑won field experience and factory discipline. Our engineers trained at the factory with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That foundation informs our approach to every commercial rooftop project. We apply the same rigorous standards when installing and commissioning Bosch RTUs across Pasadena.

Seamless project delivery

• Pre‑construction: survey, structural review, load calcs, and submittals
• Logistics: crane, rigging path, traffic coordination, and safety
• Mechanical: curbs, duct transitions, smoke detectors, and drains
• Electrical: disconnects, breakers, conduits, and labeling
• Controls: thermostats, sensors, BMS points, and sequences
• Commissioning: airflow setpoints, gas pressure, refrigerant checks, and documentation

Have an occupied space? We can stage work during off‑hours and weekends to keep your business running. Need temporary cooling? We’ll plan for it.

Retrofits, replacements, and new installs

Whether you’re replacing an aging unit or adding capacity to support growth, we make sure your new Bosch RTU fits existing curbs and ductwork, or we engineer new components when it doesn’t. We also address common pain points—hot/cold spots, poor ventilation, high static pressure—so you get a measurable upgrade in comfort and air quality, not just new equipment.

Controls, BMS, and optimization

Our team integrates Bosch rooftops with popular building management systems, optimizes economizer logic, and sets up demand‑controlled ventilation. We balance zones, verify sensor placement, and provide an owner’s sequence so your facilities team understands exactly how the system should run.

Compliance, incentives, and documentation

We prepare submittals, startup sheets, and commissioning reports for your records and AHJ requirements. We’ll also help you explore utility incentives in Los Angeles County and nearby regions that may apply to high‑efficiency rooftop upgrades.
