Commercial High-Rise HVAC Systems in Pasadena

Built for Pasadena High‑Rises

#1 AC Guys designs, installs, upgrades, and maintains commercial high‑rise HVAC systems across Pasadena and greater Los Angeles County. As a fourth‑generation, family‑owned business with 80+ years of engineering experience, we bring proven methods and practical innovation to every tower—offices, hospitality, mixed‑use, multi‑tenant, and institutional facilities.

Our mission is simple: healthy air for a healthy life. That means high‑performing systems, clean indoor air, and smart energy use—delivered safely, on schedule, and in full compliance with Title 24, CalGreen, SCAQMD requirements, and City of Pasadena permitting.

Design‑Build, Engineering, and Retrofits

From ground‑up construction to occupied retrofits, we provide end‑to‑end services tailored to the realities of high‑rise buildings:

• Concept and schematic design with load calculations and equipment right‑sizing
• Value engineering to reduce lifecycle cost without compromising comfort or code
• BIM coordination, riser diagrams, and detailed submittals
• Phased construction plans for minimal tenant disruption
• Commissioning, functional performance testing, and TAB

Our engineers are factory‑trained by leading manufacturers including Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier—so you get system selections and controls strategies aligned with real‑world performance and serviceability.

Systems We Specialize In

• VRF/VRV for flexible zoning, reduced shafts, and excellent part‑load efficiency
• Central Plants with chillers, boilers, heat pumps, and heat recovery
• Cooling Towers & Condenser Water with water treatment and automation
• DOAS & Ventilation to deliver code‑compliant outdoor air and energy recovery
• VAV/VVT air distribution, fan arrays, and high‑rise shaft strategies
• BAS/BMS Integration for analytics, demand control ventilation, and scheduling
• Electrification & Heat Pump Retrofits to meet sustainability goals

Indoor Air Quality That Matters

We design Pasadena high‑rise HVAC systems for better health and productivity:

• MERV 13+ filtration, UV‑C options, and bipolar ionization (as appropriate)
• Demand‑controlled ventilation to maintain CO₂ and VOC targets
• Proper pressurization of cores, corridors, and critical areas
• Moisture management and coil hygiene plans to protect IAQ long‑term

Code, Safety, and Compliance

High‑rise projects demand precision. We plan for:

• Title 24 and CalGreen compliance documentation
• City of Pasadena permitting support and inspection readiness
• Seismic bracing, anchorage, and rigging plans
• Smoke control coordination and stair pressurization strategies
• SCAQMD considerations for equipment and refrigerants

Commissioning, Reliability, and Maintenance

Commissioning and TAB verify performance from day one. After turnover, our proactive maintenance plans safeguard uptime, efficiency, and warranty terms:

• Predictive diagnostics through BAS trend data and sensors
• Water‑side maintenance for cooling towers and closed loops
• Seasonal changeovers, filter upgrades, and coil restoration
• Critical spares planning and emergency response protocols

When you need us most, our commercial service team offers rapid, 24/7 emergency support to protect tenants and business operations.

Construction Logistics for Towers

We coordinate cranes, street closures, and deliveries with building management and local authorities. Our team sequences work during off‑hours where needed to reduce noise and interruption for Class A offices, hotels, and residential tenants.

Transparent Process and Clear Costs

You’ll receive a dedicated project manager, a detailed scope, and transparent pricing. We provide options with lifecycle cost analyses so owners can balance capital spend, operating cost, and sustainability goals—even across multi‑tenant environments with varying usage profiles.

Serving Pasadena and Beyond
