Commercial Sensor Calibration in Santa Monica

Every degree, percentage point, and Pascal matters when you manage a commercial property in Santa Monica. #1 AC Guys ensures your HVAC and building automation sensors read accurately, so your equipment runs efficiently, occupants stay comfortable, and compliance targets are easier to meet.

What We Calibrate

• Temperature sensors (RTDs, thermistors) and thermostat verification
• Relative humidity sensors for comfort and mold prevention
• CO2 and IAQ sensors for demand‑controlled ventilation
• Static and differential pressure sensors (ducts, filters, rooms)
• Airflow and VAV box sensors for proper air distribution
• Refrigerant and water loop pressure/temperature sensors
• Outdoor air and mixed air sensors for economizer control

We also validate sensor placement, wiring integrity, labeling, and controller inputs to eliminate drift‑induced waste and nuisance alarms.

Our Calibration Process

• Assess: Review system drawings, sequences, and recent alarms to target high‑impact points.
• Verify: Inspect installation, location, shielding, and controller mapping.
• Calibrate: Use calibrated reference instruments and traceable methods to bring sensors within spec.
• Optimize: Update controller offsets, ranges, and naming; align BAS graphics with field realities.
• Document: Provide as‑found/as‑left readings, tolerances, and corrective actions.
• Report: Deliver a compliance‑ready summary supporting Title 24 and ASHRAE guidelines.

This structured approach minimizes downtime and delivers measurable results quickly.

Why Accuracy Pays Off

Misreading sensors trigger real costs—overventilation, short cycling, comfort complaints, even premature equipment wear. Precise calibration helps you cut energy spend, stabilize comfort, improve IAQ, and reduce maintenance calls. It also supports performance goals for LEED and compliance paths that reference ASHRAE 55 and 62.1.

Why #1 AC Guys

• 4th‑generation family of engineers with 80+ years in engineering
• Trained at manufacturer plants for Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China)
• Specialists in complex commercial facilities and multi‑site portfolios
• After‑hours and phased work plans to avoid tenant disruption
• Clear documentation: as‑found/as‑left, calibration certificates, point lists
• Local, responsive team serving Santa Monica and greater Los Angeles

Our mission is healthy air for healthy lives—and that begins with trustworthy sensor data.

Industries We Serve

• Office, creative, and mixed‑use buildings
• Healthcare, clinics, and labs (non‑invasive balance/pressure programs)
• Retail, grocery, and hospitality
• Education and municipal facilities
• Industrial light manufacturing and warehouses

From a single air handler to campus‑wide BAS networks, we tailor the scope to your goals.

Documentation You Can Use

We deliver actionable records: device IDs, locations, controller inputs, acceptable tolerances, reference readings, before/after values, offsets applied, and notes on placement or wiring improvements. These reports streamline audits, future service, and capital planning.
Need ongoing assurance? We can schedule recurring verification to keep drift in check and maintain compliance.

Santa Monica–Focused, County‑Wide Reach

We prioritize Santa Monica properties while covering Los Angeles County and nearby areas, including Orange County, Ventura County, and Western Riverside County. Multi‑site operators benefit from consistent methods and unified reporting across the region.

Fast Scheduling and Minimal Downtime

We offer same‑week appointments and after‑hours options to reduce tenant impact. Our techs arrive prepared with reference instruments and materials to resolve common issues on the first visit.

Integration and Optimization Support

Beyond calibration, we help align sequences of operation, economizer logic, ventilation strategies, and alarming thresholds so your BAS decisions reflect reality. Clean data in means smarter control out.

Maintenance and Calibration Plans

Choose one‑time calibration or a plan that includes seasonal checks, filter differential pressure verification, sensor cleaning where applicable, and documentation updates. Plans help maintain stable comfort and predictable operating costs.
