Commercial Sensor Calibration in Fontana (AC PRO–Compatible)

Why precise calibration matters for Fontana facilities

When HVAC and building automation sensors drift, energy costs rise, comfort suffers, and indoor air quality can fall below targets. In Fontana’s demanding commercial environments—warehouses, logistics hubs, offices, schools, healthcare—accurate readings are essential for ASHRAE ventilation, California Title 24 compliance, and steady operations. Regular calibration protects your equipment, your occupants, and your budget.

What we calibrate

• Temperature sensors and thermostats (supply, return, zone)
• Relative humidity sensors for IAQ and dehumidification control
• CO2 and VOC sensors for demand-controlled ventilation
• Static pressure sensors (duct and building) to stabilize airflow
• Airflow and velocity probes for VAV boxes, RTUs, and AHUs
• Economizer outdoor air temperature and enthalpy sensors
• Refrigerant line temperature and pressure transducers
• Differential pressure sensors across filters and coils

We service mixed-brand systems and are fully compatible with AC PRO components, ensuring consistent results across your portfolio.

AC PRO–friendly service without disruption

Whether your site deploys AC PRO–sourced equipment or compatible components, our field engineers calibrate and document sensors so your controls logic works exactly as designed. We follow manufacturer specifications, preserve warranties, and replace out-of-tolerance sensors with like-for-like parts when needed—streamlining procurement through local distribution and minimizing downtime.

Our proven process

• Discovery: Review equipment schedules, sequences of operation, recent alarms, and trends.
• Baseline readings: Capture current values and environmental conditions for each targeted point.
• NIST-traceable references: Apply certified standards to test sensors at multiple points across their operating range.
• Adjustments and corrections: Calibrate, offset, or replace hardware as needed to meet tolerance.
• Functional verification: Confirm stable readings under load and validate points in your BAS.
• Documentation: Deliver calibration certificates, before/after values, tolerances, and recommendations.

This method reduces variance, supports audits, and improves controllability so your equipment cycles less and lasts longer.

Reporting and compliance you can trust

Every visit includes a clear report with point-by-point results, pass/fail status, tolerance bands, and corrective actions. We align with ASHRAE guidance and California Title 24 best practices and maintain traceability to NIST standards for your QA/QC records. You get actionable maintenance intervals and a priority list ranked by energy and IAQ impact.
