Glendale Commercial BAS (Building Automation System) Maintenance

As a family‑owned Los Angeles company now in its fourth generation, #1 AC Guys specializes in commercial BAS maintenance for Glendale properties—from offices and retail centers to healthcare, education, hospitality, and mixed‑use spaces. Our mission is simple: healthier air for healthier lives. We translate 80+ years of engineering know‑how into reliable building performance, lower lifecycle costs, and confident facility teams.

What our BAS maintenance includes

• Controls health checks: controllers, networks (BACnet/IP, BACnet MS/TP, Modbus), and supervisory servers
• Field device verification: sensors, actuators, VFDs, valves, economizers, and safeties
• Airside optimization: RTUs, AHUs, VAVs/VVTs, demand control ventilation, and ventilation resets
• IAQ focus: CO₂, PM, VOC monitoring, filtration checks, and clean‑air sequence validation
• Sequence of Operation tuning: scheduling, setpoint strategies, deadbands, and lockouts
• Firmware and patching: secure updates for controllers, gateways, and operator workstations
• Database management: backups, point cleanup, naming standards, and trend/log retention
• Alarm rationalization: nuisance alarm reduction and priority mapping for faster response
• Energy management: trend analysis, fault detection, and actionable savings recommendations
• Documentation and training: updated as‑built controls docs and brief on‑site operator coaching

Whether your site uses AC PRO–supplied HVAC equipment, integrates VRF/mini‑split systems, or ties into lighting and ventilation controls, our engineers maintain the BAS end to end and leave it better documented than we found it.

Expertise you can trust

We are a fourth‑generation family of engineers with 80+ years of engineering experience. Our team has been factory‑trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That background, combined with real‑world commissioning and maintenance across large California facilities, means we can diagnose root causes, not just symptoms—especially in complex, multi‑vendor environments common in Glendale commercial buildings.

AC PRO–equipped buildings: what we support

From AC PRO–supplied rooftop units and air handlers to packaged systems, we service the connected BAS that orchestrates comfort, ventilation, and energy performance. We optimize how your BAS commands equipment, verifies sensor accuracy, and sequences airside strategies for dependable indoor air quality and reduced energy use.

Results you can measure

• Fewer alarms and callouts through root‑cause fixes and alarm rationalization
• Lower energy spend via refined schedules, resets, and ventilation strategies
• Improved IAQ and comfort stability with validated sensors and tuned sequences
• Higher system resilience through backups, patches, and documentation
• Clear reporting: before/after trends, findings, and prioritized actions

Service plans for Glendale facilities

• Preventive BAS Care: scheduled inspections, backups, logs, and essential tuning
• Performance BAS Care: adds analytics, alarm cleanup, and energy optimization
• Premier BAS Care: includes seasonal re‑tuning, operator coaching, and KPI reporting

All plans start with a no‑pressure walkthrough, scope definition, and a fixed, transparent proposal.

Industries we serve

• Office, retail, mixed‑use, and multi‑tenant commercial
• Healthcare clinics and medical office buildings
• Hospitality and entertainment
• Education and municipal
• Light industrial and logistics

Glendale and greater Los Angeles coverage

We dispatch quickly across Glendale, Los Angeles County, and nearby areas including Burbank, Pasadena, and the broader region—extending to Orange County, Ventura County, and Western Riverside County when required.

Our process

Discovery and scope → On‑site assessment and data pull → Priority action list → Execution and documentation → KPI report and next‑step plan. We communicate clearly with property managers, facility directors, and O&M teams at every step.

Frequently asked questions

Can you work in live, occupied spaces?
Yes. We schedule around tenants and critical operations to minimize disruption.

Do you handle multi‑vendor controls?
Absolutely. We routinely maintain mixed BAS environments common in Glendale buildings.

How fast can you start?
Site size varies, but we can typically begin with a walkthrough and initial stabilization within days.
