Commercial High‑Rise HVAC Systems in Rialto

Engineering‑Led HVAC for Tall Buildings

High‑rise HVAC is not just bigger equipment—it is a different discipline. With 80+ years of engineering heritage, #1 AC Guys brings the rigor your Rialto project deserves: right‑sized system selection, airflow balance across floors, pressure management, and indoor air quality (IAQ) that supports healthy, productive spaces.

• Design‑build and plan‑spec delivery
• Retrofit and central plant upgrades
• VRF/VRV, chilled water, boilers, heat pumps
• Dedicated Outside Air Systems (DOAS) and energy recovery
• VAV/VVT, fan arrays, economizers, and heat recovery
• DDC/BMS integration and optimization
• Commissioning, TAB, and continuous monitoring

Our mission is simple: healthier air for healthier lives—without compromising performance or budget.

Systems and Technologies We Excel In

Our factory‑trained team—Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China)—delivers high‑efficiency, code‑compliant systems tailored to towers and vertical campuses.

• VRF/VRV for high‑rise: zoning flexibility, heat recovery across exposures, low riser impact
• Chilled water plants: air‑cooled and water‑cooled configurations, pump optimization, variable primary
• DOAS for IAQ: decoupled ventilation, energy recovery wheels/plates, demand control ventilation
• Air handlers and fan walls: redundancy and sound attenuation for critical floors
• Smart controls: open‑protocol DDC/BMS, analytics, fault detection and diagnostics

We design for lifecycle value—ease of service, parts availability, and energy performance that keeps operating costs predictable.

Code, Compliance, and Execution

We navigate California Title 24 energy standards, CALGreen objectives, and local permitting while coordinating with your architect, structural, electrical, and fire‑life‑safety teams. Expect clean drawings, clash‑free routing, and phasing that protects tenants and schedules.

• Load calculations, equipment schedules, and sequences of operation
• BIM/Revit coordination for risers, shafts, and mechanical rooms
• Seismic supports and bracing details
• Commissioning plans, TAB, and owner training

From submittals to final sign‑off, we keep documentation tight and communication clear.

Healthy Air as a Design Standard

Our mission is healthy air in every occupied space. We specify filtration, ventilation rates, and controls that meet or exceed best practices for IAQ in high‑rise buildings.

• MERV‑rated filtration strategies and change‑out plans
• Ventilation right‑sizing to occupancy and use
• Humidity management for comfort and mold prevention
• Air quality monitoring and trending

Cleaner air, fewer complaints, and better productivity—designed in from day one.

Construction, Retrofit, and Phasing

Occupied towers demand precision. We plan cutovers, crane lifts, and riser work to minimize disruption while protecting people and property.

• Night/weekend changeovers when required
• Noise and dust controls with clear signage
• Temporary cooling/heating plans
• Tenant communication and safety coordination

Our goal is a smooth turnover—no surprises, no rework, no finger‑pointing.

Service and Maintenance for High‑Rise Portfolios

Performance is earned daily. Our maintenance programs help prevent breakdowns, extend asset life, and control energy spend.

• Predictive and preventive maintenance
• Seasonal start‑ups, shutdowns, and fine‑tuning
• Sensor calibration and controls optimization
• Rapid diagnostics and repair with OEM‑aligned best practices

Keep occupants comfortable and budgets steady with proactive care tailored to your building’s systems.
