Commercial Sensor Calibration in Anaheim

Accurate sensors are the foundation of efficient HVAC and reliable building automation. In Anaheim’s diverse commercial environments—from Anaheim Canyon to the Resort District—#1 AC Guys keeps your data trustworthy so your equipment can control comfort, indoor air quality, and energy spend with confidence.

What we calibrate

• Temperature sensors: RTDs, thermistors, duct and space probes, immersion wells, surface strap‑on
• Relative humidity sensors and transmitters
• Static and differential pressure sensors: duct, filter, and space applications
• Refrigerant pressure and temperature transducers for VRF/VRV, chillers, and RTUs
• Airflow stations and VAV flow sensors
• CO2 and IAQ sensors (including PM and TVOC where applicable)
• Economizer and outdoor air sensors (OAT/OAH), supply/return air sensors
• Thermostats and wall modules (verification and calibration)

We tune sensors across BAS platforms and mechanical equipment so command, control, and trends match real‑world conditions, not guesswork.

Why calibration matters

• Energy savings: Misreading sensors cause overcooling, overheating, and excessive ventilation. Calibration can curb waste and stabilize loads.
• Comfort and productivity: Correct readings keep temperatures steady and humidity in range for occupants and customers.
• Healthy indoor air: Accurate CO2 and airflow data support proper ventilation—our core mission is healthy air for healthy living.
• Compliance and QA: Supports Title 24, ASHRAE guidance, and internal quality programs with traceable records.
• Asset protection: Proper discharge air temps and pressures help prevent equipment stress and premature failures.

Our calibration process

• Discovery and planning: Review site drawings, BAS points, sequences of operation, sensor locations, and access constraints.
• Baseline testing: Compare sensor outputs to reference instruments; note offsets, drift, noise, and response time.
• Adjustment and correction: Apply field calibration, offset, or span adjustments; replace failed devices when needed.
• BAS verification: Update point mapping as required, confirm alarms, trends, and sequences reflect corrected values.
• Documentation: Provide clear reports with before/after readings, device IDs, locations, and recommendations. NIST‑traceable methods available upon request.
• Ongoing care: Set up periodic calibration schedules aligned to occupancy, critical loads, and compliance calendars.

We coordinate around production windows and tenant schedules with options for early mornings, evenings, or weekend work to reduce disruption. For campuses and towers, we stage multi‑floor rollouts and maintain continuous communication with facilities teams.

Engineered expertise you can trust

#1 AC Guys is a 4th‑generation family of engineers with 80+ years of experience in engineering, specializing in commercial and residential HVAC—including large, complex projects. Our engineers have trained at manufacturer facilities for Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That factory‑level insight shows up in our precision, documentation, and ability to solve difficult control issues others avoid.

Anaheim and regional coverage

Headquartered in Southern California, we serve Anaheim, Orange County, Los Angeles County, Ventura County, and Western Riverside County. Whether you’re near the Platinum Triangle, Anaheim Canyon Business Park, or the Resort District, our teams arrive equipped with calibrated reference instruments and spare parts to keep your project on schedule.

Integration with your BAS and mechanical systems

We work across rooftop units, VRF/VRV systems, chillers, boilers, VAV/FPB terminals, economizers, and exhaust systems. On the controls side, we validate points, fine‑tune sensor locations, and coordinate with your controls contractor to ensure sequences respond correctly after calibration. If a sensor is poorly placed, we provide relocation recommendations based on airflow, stratification, and serviceability.

Common Anaheim use cases include comfort optimization for retail and hospitality, ventilation assurance for classrooms and healthcare spaces, and process‑critical stability for light industrial and food service. Our goal is consistent, healthy air with the lowest reasonable energy use.

What to expect

• Clear scope and pricing before we begin
• Professional, safety‑first technicians and engineers
• Reference instruments verified against NIST‑traceable standards
• Actionable reports with prioritized recommendations
• Follow‑up support and proactive maintenance plans

Every project ends with a practical roadmap—what to fix now, what to monitor, and what to schedule next—so your facilities team can act with confidence.

Ready to restore accuracy?

If your BAS trends don’t match what occupants feel, if energy use seems high, or if alarms are inconsistent, it’s time to recalibrate. Contact #1 AC Guys for commercial sensor calibration in Anaheim. We’ll quickly assess your site, align on goals, and deliver the precise measurements your building deserves—because healthy air starts with accurate data.

Looking beyond Anaheim? We also support nearby cities and business corridors across Orange County, plus Los Angeles County, Ventura County, and Western Riverside County—bringing the same engineered rigor, responsive scheduling, and results‑driven service.
