Commercial Gree Rooftop Unit (RTU) Installation in Long Beach, CA

As local HVAC engineers serving Long Beach and the greater Los Angeles County area, #1 AC Guys focuses on code‑compliant, efficiency‑first Gree rooftop unit (RTU) installations for commercial properties. Our mission is simple: healthier indoor air and dependable comfort with smart engineering that lowers total cost of ownership.

What’s Included in a Professional Gree RTU Installation

• Engineering assessment: heat load, ventilation, and electrical review
• Title 24 and local code compliance, permit handling, and inspections
• Crane lift planning, rigging, traffic coordination, and safety oversight
• Roof curb adapters, seismic considerations, and weatherproofing
• Ductwork modifications, economizer integration, and balancing
• Controls setup: smart thermostats and BMS integration (e.g., BACnet/Modbus)
• Commissioning and manufacturer start‑up procedures
• Training for your facilities team and maintenance plans

We manage projects end‑to‑end, coordinating closely with property managers, GCs, and tenants to minimize disruption. Our crews keep job sites clean, document progress, and deliver clear communication from proposal to final inspection.

Why Choose Gree RTUs for Long Beach Buildings

Gree rooftop units offer reliable performance with high‑efficiency components, advanced controls options, and flexible configurations for offices, retail, restaurants, warehouses, and medical/office campuses. In Long Beach’s coastal climate, we specify protective measures for corrosion resistance, proper ventilation strategies, and filtration upgrades aligned with your air quality goals.

• Energy performance: right‑sized capacity, staged or variable operation
• Comfort and air quality: ventilation control, dehumidification, and MERV filter options
• Controls: integration with building automation for scheduling and remote monitoring
• Serviceability: thoughtful layout for faster maintenance and reduced downtime

Every installation follows manufacturer guidance and best‑practice commissioning to help protect equipment and ensure consistent performance.

Our Step‑by‑Step Process

1. Site walk and assessment: We evaluate roof access, structure, electrical, gas, and ductwork. We capture measurements for curb adapters and airflow needs.
2. Engineering and proposal: You receive a clear scope with load calculations, equipment selections, and a transparent timeline and price.
3. Permits and logistics: We manage permits, inspections, crane scheduling, traffic control, and safety planning.
4. Installation day: Old unit removal, curb prep or adapter, Gree RTU placement, utilities, duct connections, controls, and weatherproofing.
5. Start‑up and commissioning: Airflow balancing, control programming, and verification under real load conditions.
6. Turnover: O&M documentation, team training, and recommended maintenance plan.

Engineers First: Complex Roofs and Tight Sites

From tight downtown streets to sensitive campuses, we plan lifts and staging with precision to keep your business operating. Our fourth‑generation engineering background and factory training with Gree (China), Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), and Hier (China) equips us to solve challenging layouts, long duct runs, and mixed‑use ventilation needs.

Healthy Air, Lower Lifecycle Costs

We align equipment selection and controls with your indoor air quality targets—ventilation rates, economizers for fresh air, and filtration strategies (e.g., higher MERV where appropriate). The result: cleaner air, fewer comfort complaints, and energy savings that continue long after installation.

When to Consider RTU Replacement

• Frequent repairs, rising utility costs, or uneven temperatures
• Non‑compliant ventilation or aging equipment near end of service life
• Facility expansion or tenant improvements requiring more capacity
• Obsolete controls that can’t meet scheduling or monitoring needs

A new Gree rooftop unit, correctly sized and commissioned, can stabilize comfort, reduce energy spend, and simplify maintenance.
