Commercial High-Rise HVAC Systems in Los Angeles

Design‑Build Engineering for LA Towers

High‑rise buildings demand HVAC systems that balance comfort, uptime, and energy performance. #1 AC Guys brings four generations of engineering discipline to commercial high‑rise HVAC in Los Angeles. We provide full design‑assist and design‑build services, including load calculations, equipment selection, riser strategy, acoustic planning, and BIM coordination with architects, structural, and MEP trades. Our team navigates LADBS permitting, Title 24 compliance, CALGreen requirements, and SCAQMD rules to keep your schedule on track and your project code‑ready.

Systems We Deliver

• VRF/VRV heat pump and heat‑recovery systems for mixed‑mode and tenant‑by‑tenant control.
• Chilled‑water and condenser‑water plants, cooling towers, and hydronic risers with VFDs and smart sequencing.
• Dedicated Outdoor Air Systems (DOAS) with energy recovery, economizers, and demand‑controlled ventilation for IAQ and efficiency.
• VAV, fan‑coil, water‑source heat pumps, and pressurization systems for lobbies, stairwells, and elevator shafts.
• Garage exhaust with CO/NO2 monitoring and variable airflow strategies to reduce energy use.
• Electric heat pump retrofits and decarbonization pathways that support local sustainability targets.
• Filtration upgrades (MERV 13+), UV‑C at coils, and ventilation strategies that support healthier indoor air.

Controls, BMS & Integration

We integrate and program open‑protocol controls (BACnet/Modbus) to tie equipment, VFDs, and terminal units into your Building Management System. Our approach includes point‑to‑point testing, trend logging, and fault detection analytics that help property teams visualize performance and act before small issues become downtime. Remote monitoring options enable proactive dispatch and data‑driven maintenance.

Construction Logistics & Safety

High‑rise work requires precision planning. We coordinate crane picks, street closures, and off‑hours tie‑ins to minimize impact on occupants and neighbors. Our installers follow CBC seismic bracing requirements, SMACNA standards, and safety protocols for fall protection, confined spaces, and hot work. Expect clean job sites, clear daily communication, and documented QA/QC at every milestone.

Commissioning, Testing & Documentation

From factory start‑up through performance validation, our commissioning process includes TAB, controls verification, alarm/sequence testing, and functional performance testing aligned with design intent and Title 24. Closeout packages include as‑builts, O&M manuals, warranties, and hands‑on training for facility teams so you start strong on day one.

Lifecycle Service & Preventive Maintenance

Keep your high‑rise running efficiently with a maintenance program tailored to occupancy and equipment type. We provide seasonal start‑ups and shutdowns, filter and belt changes, coil and tower cleaning, water treatment oversight, refrigerant management, vibration analysis, and routine controls checks. With 24/7 emergency response and stocked service vehicles, we resolve issues fast and protect your investment.

Trusted by Owners, GCs & Property Teams

Whether it’s a new tower, phased tenant improvements, or a plant modernization in an occupied building, our team is built for complex, schedule‑driven work. We collaborate with owners, developers, general contractors, and facility managers to deliver transparent budgets, value‑engineering options, and a no‑surprises execution plan that maintains comfort and business continuity.

Brands & Training

Our engineers and technicians have factory training from leading manufacturers, including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That means faster diagnostics, compliant installations, and systems tuned to OEM best practices—whether we’re building to spec or proposing a performance‑driven alternative.
