Commercial High‑Rise HVAC Systems in Los Angeles

High‑rise towers in Los Angeles challenge HVAC systems with stack effect, tight shafts, long risers, mixed occupancies, and strict codes. #1 AC Guys brings an engineering‑first approach that aligns design intent with real‑world constructability and lifetime serviceability. Our goal is simple: dependable comfort, clean indoor air, and efficient operation—floor by floor, zone by zone.

Why high‑rise HVAC is different

As buildings grow taller, airflow, heat transfer, and pressure behave differently. That is why we start with calculations and modeling before we touch hardware. We translate physics into practical solutions that installers, inspectors, and facility teams can trust.

• Stack effect and pressure control across stairwells, elevators, and shafts
• Mixed‑use zoning for offices, retail, amenities, and parking levels
• Long vertical refrigerant and hydronic runs with oil return and pump head considerations
• Equipment placement, crane logistics, roof loads, and acoustic mitigation
• Smoke control coordination and life‑safety interfaces
• Title 24 compliance, controls sequencing, and commissioning

Our engineering‑led process

• Discovery and site walk: verify constraints, access, and existing conditions
• Load calculations and energy modeling: support right‑sized, efficient designs
• System selection: VRF/VRV, chilled water, heat pumps, DOAS—aligned to goals and budget
• Coordination: BIM/MEP, riser diagrams, shaft allocations, and roof layouts
• Installation: code‑compliant workmanship, clean routing, labeling, and QA/QC
• Controls and integration: BAS strategies, sequences of operation, trending, alarms
• Testing, adjusting, and balancing (TAB) plus commissioning with documentation
• Turnover and training: clear O&M manuals, maintenance plans, and staff coaching
• Lifecycle support: proactive maintenance, performance tuning, and upgrades

Systems and technologies we work with

• VRF/VRV: high‑efficiency, zoning‑rich systems suited to towers with diverse loads and schedules
• Chilled water plants: air‑cooled or water‑cooled with cooling towers, optimized for part‑load
• Heat pumps and boiler plants: hybrid strategies for comfort and decarbonization goals
• DOAS and ERV/HRV: dedicated outdoor air with energy recovery for better IAQ and code compliance
• VAV/VVT and pressure control: stable temperatures and airflow across long vertical runs
• Smoke control coordination: mechanical interfaces that respect life‑safety design
• Controls and BAS integration: open protocols, metering, trending, and demand response
• Filtration and IAQ enhancements: MERV‑13+ filtration, UV‑C options, and monitoring
• Energy optimization: VFDs, economizers, sequencing, and retro‑commissioning

Healthy indoor air, delivered responsibly

Our mission is healthy air for healthy lives. We design for clean ventilation air, right‑sized filtration, moisture control, and verifiable performance. Strategies can include MERV‑13+ filters, UV‑C in coils or air handlers, dedicated outdoor air with energy recovery, and CO₂‑based ventilation control. We apply these measures according to code, manufacturer guidance, and the building’s operational needs—balancing IAQ, comfort, and energy.

Compliance and documentation in Los Angeles

We navigate Title 24, Los Angeles Mechanical Code, and utility requirements while keeping your schedule moving. Expect permit‑ready submittals, sequences of operation for BAS, commissioning plans, and TAB reports. Our deliverables make it easier for inspectors, facility teams, and future service technicians to understand and maintain the system.
