Commercial Rooftop Unit (RTU) Installation in Long Beach

Why #1 AC Guys for Your Long Beach RTU?

Four generations of HVAC engineers guide every project we build. With 80+ years of practical know‑how and factory training from Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea, Gree, and Haier, we install rooftop units that perform reliably in coastal, high‑salt environments. As a family business, we combine big‑project capability with responsive service and clean workmanship your tenants and customers will notice.

Turnkey Commercial RTU Installation

We streamline the entire process so you don’t have to coordinate multiple vendors:
• Site survey, load calculations, and airflow verification
• Equipment right‑sizing and energy modeling for Title 24 compliance
• Curb adapters and structural coordination with seismic/wind requirements
• Duct transitions, economizers, smoke detectors, and CO2/enthalpy sensors for DCV
• Electrical, gas, condensate management, and controls integration (BACnet compatible)
• City of Long Beach permits and inspections, plus utility incentive guidance (SCE/SoCalGas)
• Crane lift planning, traffic/safety coordination, rigging, and disposal of old equipment
• Commissioning, startup, and Title 24 acceptance testing with proper documentation

Built for Coastal Long Beach Conditions

Salt air can shorten the lifespan of standard equipment. We specify corrosion‑resistant coils and coatings, marine‑grade fasteners, and proper clearances to protect heat exchangers, compressors, and electronics. We also prioritize economizers and variable‑speed fans to capitalize on the coastal climate’s mild temperatures, cutting operating costs while maintaining stable indoor comfort.

Project Types We Support

• Office buildings and co‑working spaces
• Restaurants and food service (grease, make‑up air, and demand spikes)
• Retail and mixed‑use spaces
• Warehouses and light industrial
• Healthcare and clinics (enhanced filtration, ventilation strategies)
• Schools and houses of worship
Whether it’s a like‑for‑like RTU swap with a curb adapter or a full redesign with zoning and controls, we deliver on schedule with minimal downtime.

RTU Options and Controls

We install gas/electric packaged units, heat pump RTUs, cooling‑only systems, and high‑efficiency equipment with VFD supply fans. Integrations include:
• Economizers for free cooling and indoor air quality
• Demand control ventilation with CO2 sensors
• Smart thermostats and building automation (BACnet/Modbus)
• Advanced filtration (MERV upgrades) and IAQ enhancements
• Remote monitoring and alerting for uptime and energy management

Safety, Compliance, and Documentation

Our installations meet or exceed California Mechanical, Electrical, and Energy Codes. We handle structural/seismic anchoring, clearances, and roof protection, and provide as‑built documentation, O&M manuals, and owner training. Expect clean job sites, protected roofing, and coordinated inspections to keep your timeline tight and predictable.

Crane Day Done Right

We plan the lift, schedule street access if needed, coordinate rigging, and verify roof readiness before the crane arrives. Our team communicates with property managers and tenants to reduce disruption and ensure safety for everyone on site.

Energy Savings and Incentives

We help you capture utility incentives and long‑term savings through high‑efficiency RTUs, economizers, and controls upgrades. With accurate commissioning and airflow balancing, we target lower kWh/therm use without sacrificing comfort—or your lease obligations.

Healthy Air Is Our Mission

Healthy air supports healthy lives. We engineer ventilation rates, filtration upgrades, and humidity control that serve occupant wellness as well as code. It’s our family mission in every building we touch.

Service Area

Headquartered in Los Angeles, we serve Long Beach and all of Los Angeles County, plus nearby Orange County, Ventura County, and Western Riverside County. If your property portfolio spans multiple jurisdictions, our permitting team keeps projects moving across borders with consistent standards and documentation.

Transparent Pricing and Warranties

We provide itemized proposals, clear scopes, and options so you can choose the best lifecycle value. Expect strong workmanship warranties and manufacturer coverage—paired with maintenance programs that protect your investment and validate warranty terms.

Maintenance Plans

Post‑installation, our preventative maintenance keeps filters fresh, coils clean, and economizers calibrated. Regular inspections minimize breakdowns, optimize energy use, and extend RTU life—which means fewer interruptions for your business and happier occupants.
