Long Beach Fujitsu Commercial Rooftop Unit (RTU) Installation

Why Long Beach businesses choose #1 AC Guys

We are a fourth‑generation family of engineers with 80+ years of engineering experience, focused on commercial HVAC that keeps people comfortable and operations uninterrupted. Our mission is simple: healthier indoor air for healthier lives. In Long Beach and throughout Los Angeles County, our team designs, installs, and commissions Fujitsu rooftop units with an engineering‑first mindset—built for reliability, serviceability, and energy performance in coastal environments.

• Factory‑trained at Fujitsu in Japan; experienced with complex commercial installs
• Design‑build delivery: load calcs, duct/curb design, electrical and controls coordination
• Crane logistics, safety plans, and roof protection executed to strict standards
• Title 24 strategies, economizers, and demand‑controlled ventilation
• Coastal hardening for salt air and wind exposure
• Clean documentation and commissioning for predictable operation

Engineering‑led Fujitsu RTU installation

Every rooftop is different. We start with a site survey to measure structure, roof membrane, access, electrical service, gas (if applicable), and existing curb details. We perform load calculations and right‑size the Fujitsu RTU to your occupancy, envelope, and ventilation needs, then specify economizers, filtration level (MERV‑13+ as needed), and controls. Where existing ductwork or curbs do not match, we design curb adapters and verify static pressure to protect motor longevity and comfort.

For coastal Long Beach, we recommend corrosion‑resistant coatings, marine‑grade fasteners, and protective placement of controls. Penetrations are sealed with compatible materials, and we plan roof protection and traffic paths to preserve your warranty and prevent damage.

What to expect in our process

• Assessment and data capture: roof, structure, utilities, airflow, and code checks
• Design and scope: equipment selection, curb/duct details, control sequences, and IAQ options
• Proposal and scheduling: transparent pricing, crane plan, and project milestones
• Permitting and submittals: plans, Title 24 documentation, and coordination with the AHJ
• Procurement and prefabrication: curb adapters, vibration isolation, rails, and rigging points
• Crane day: OSHA‑compliant lift plan, traffic control, roof protection, and safe rigging
• Installation: setting the Fujitsu RTU, duct/electrical/gas connections, drains, and sensors
• Startup and commissioning: airflow balance, economizer tuning, controls integration, and trend logs
• Turnover: O&M manuals, training, and a clear maintenance plan

Fujitsu expertise you can trust

Our team is factory‑trained at Fujitsu in Japan, with additional manufacturer training at Mitsubishi Electric in Thailand, Midea in China, Gree in China, and Haier in China. That depth of training informs our commissioning approach—verifying refrigerant charge, static pressure, ventilation rates, and control sequences so your Fujitsu rooftop unit performs as engineered.

Healthier air, better productivity

We design for indoor air quality from the start: correct outside air, tight ducts, appropriate filtration, and smart economizer logic. Options such as MERV‑13 filtration, UV‑C at coils, and demand‑controlled ventilation can help reduce particulates and odors while improving comfort. Our goal is stable temperatures, balanced humidity, and clean air for the people who use your building every day.

Applications

• Office, retail, and mixed‑use buildouts
• Medical, dental, and wellness suites
• Restaurants and hospitality spaces
• Warehouses, light industrial, and labs
• Education and civic facilities

Service area

Based in Los Angeles, we serve Long Beach and all of Los Angeles County, plus nearby areas: Orange County, Ventura County, and Western Riverside County. If your project borders these regions, ask us—our commercial team regularly mobilizes for multi‑site installations.

Lifecycle support

A great installation is only the beginning. We offer planned maintenance tailored to Fujitsu RTUs: coil cleaning, torque checks, economizer verification, filter changes, and data‑driven performance reviews. Proactive care helps maintain efficiency, uptime, and indoor air quality throughout the life of the equipment.
