Commercial BAS (Building Automation System) Maintenance in Pasadena

Your BAS is the control center that ties together air handlers, rooftop units, VRF gateways, VAVs, fans, and IAQ strategies. When it drifts out of tune, costs climb and comfort slips. Our Commercial BAS Maintenance in Pasadena focuses on reliability, indoor air quality, and measurable energy performance—without disrupting your operations. We combine deep controls knowledge with practical HVAC field experience to keep your system stable, documented, and future‑ready.

What our BAS maintenance includes

Our engineer‑led checklist targets the issues that impact uptime, IAQ, and energy the most.

• Controller health review, backups, and point database verification
• BACnet/IP and MS/TP network diagnostics, routing/BBMD checks, and switch hygiene
• Sensor calibration (temp, RH, CO2), airflow/static pressure validation, and actuator testing
• Sequence of operations (SOO) verification and optimization for local climate and load
• VAV box tuning, damper/economizer function tests, and ventilation rate checks
• Trend setup and analytics for KPIs (kWh/ton, IAQ, comfort bands, runtime)
• Alarm rationalization to eliminate noise and surface true root‑cause events
• Cyber‑hygiene basics: roles, passwords, backups, firmware planning, and change logs
• Graphics, naming standards, and floorplan updates for fast troubleshooting
• Title 24 and best‑practice review to align schedules, setbacks, and demand control ventilation

Why #1 AC Guys for Pasadena commercial sites

We are a fourth‑generation family business serving Los Angeles County and nearby areas, with 80+ years in engineering. Our mission is simple: healthier air for healthier lives. We excel on large, complex facilities where precision controls and reliable documentation matter. Our teams were trained at manufacturers’ facilities including Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). We pair that rigor with practical, on‑the‑ground maintenance that keeps your BAS predictable and your occupants comfortable.

We support AC PRO–distributed components and help you align parts standards across sites—reducing downtime and simplifying inventory. One call, one accountable team, multiple buildings covered.

Open protocols and integration

We work across common open protocols—BACnet/IP, BACnet MS/TP, Modbus, and Lon—so you are not boxed into a single vendor roadmap. Whether your plant includes RTUs, AHUs, boilers, chillers, VRF/mini‑splits via gateways, or economizers, we keep the automation layer coordinated and transparent.

Healthy air, comfort, and compliance

Indoor air quality is central to our maintenance philosophy. We verify ventilation strategies, demand‑controlled ventilation logic using CO2, and filtration approaches in coordination with your mechanical equipment and schedules. Comfort bands, humidity targets, and pressurization goals are balanced against energy and code requirements, including California Title 24 best practices.

Service plans that fit your operation

Choose quarterly, biannual, or annual plans based on building size, occupancy, and risk tolerance.
• Preventive visits with documented tasks and trends
• Priority response for stabilization needs
• Annual SOO review to capture operational changes and new code guidance
• Budget roadmap for lifecycle upgrades and phased improvements

Deliverables you can act on

• BAS baseline report with scorecard (network, controls, IAQ, energy KPIs)
• Asset inventory and critical spares aligned with AC PRO availability
• Updated point lists, naming standards, and floorplans/graphics
• Alarm matrix and escalation guidance
• SOO fine‑tuning recommendations with savings and comfort impacts

Industries we support

Offices and creative spaces, healthcare and clinics, retail and restaurants, education and labs, houses of worship, hospitality, and multifamily common areas—anywhere a stable BAS protects comfort, equipment life, and operating costs.
