Commercial Amana Rooftop Unit (RTU) Installation in Long Beach

As your commercial HVAC partner in Long Beach, we design and install Amana rooftop units (RTUs) with an engineering-first approach. That means every decision—from equipment selection to curb adapters and crane logistics—is grounded in calculations, code, and real-world reliability.

Engineer-led design-build for Amana RTUs

We begin with onsite measurements and load calculations to select the right Amana RTU capacity and airflow. We verify duct static pressure, plan proper supply/return transitions, and match or fabricate curb adapters to fit your roof opening. Our designs account for condensate routing, gas piping, electrical single-line, clearances, smoke detection interfaces, and seismic anchorage appropriate for Southern California conditions. The result is a rooftop package unit that delivers the CFM, ESP, and ventilation your space requires—without guesswork.

Permits, code, and Title 24 compliance in Long Beach

We prepare permit-ready documentation, coordinate with the City of Long Beach and Los Angeles County where applicable, and handle Title 24 requirements for economizers, controls, and efficiency. From equipment schedules to control narratives and acceptance testing coordination, we make compliance straightforward—so approvals and inspections are smooth and predictable.

Crane lift logistics and rooftop safety

Our team plans the lift around your operations and the neighborhood traffic flow, minimizing downtime while protecting your roof and people.

• Pre-lift survey, rigging plan, and load path verification
• Street or lot coordination as needed with property management
• Roof protection and staging to avoid membrane damage
• Seismic anchorage and curb sealing to prevent leaks
• Weather windows and contingency planning

Controls, ventilation, and commissioning

We configure economizers, demand-control ventilation (CO2), and schedules for comfort and savings. Whether you need simple thermostats or BAS integration (BACnet-ready solutions), we set up your Amana RTU to deliver consistent results. Commissioning includes airflow verification, temperature splits, gas pressure checks (for gas/electric models), electrical validation, and documentation that supports manufacturer warranty. When required, we coordinate test and balance to confirm performance.

Healthy indoor air—our core mission

Clean air is foundational to comfort and productivity. We tune your Amana RTU with IAQ in mind from day one.

• Right-size outside air per ASHRAE recommendations for your occupancy
• High-efficiency filtration options (including MERV upgrades)
• Proper economizer setup for free cooling when conditions allow
• Drainage, coil protection, and cleanable access for long-term hygiene

Replace vs. repair—when an Amana RTU change-out is smart

We help you weigh total cost of ownership, not just today’s repair ticket. Consider replacement if you experience:

• Frequent breakdowns or comfort complaints that disrupt operations
• Rising energy bills and short cycling despite regular maintenance
• Obsolete controls or ventilation that can’t meet code or IAQ goals
• Leaks or failing heat exchangers on aging units
• Capacity mismatches after tenant improvements or layout changes

We can provide an apples-to-apples comparison showing energy savings, incentives where available, and payback timelines.

Turnkey scope for commercial Amana RTU installation

We provide a single accountable team for the entire RTU change-out.

• Site walk, engineering review, and equipment submittals
• Curb adapter design or fabrication, roof coordination, and sealing
• Electrical, gas, and controls integration with clear labeling
• Economizer/DCV setup and sequence verification
• Startup, commissioning, documentation, and training for your staff
