Commercial Sensor Calibration for Carrier Systems in Orange, CA

As buildings evolve, sensors age, get contaminated, or lose accuracy after service events. Our commercial calibration program for Carrier systems brings your data back to truth, enabling smarter control, lower kWh/therms, and healthier indoor air across your facility in Orange, CA.

What we calibrate on Carrier commercial HVAC

• Space, supply, return, and mixed-air temperature sensors
• Relative humidity sensors (space and duct-mounted)
• CO2 and IAQ sensors for demand-controlled ventilation
• Static and differential pressure sensors (duct, filter, VAV, hydronic)
• Airflow stations, VAV flow rings, and pitot-based measurements
• Economizer outdoor air temperature and enthalpy sensors
• Refrigerant temperature/pressure sensors (suction, discharge, liquid)
• Chilled and hot water sensors (temperature, DP)

We also verify device addressing and trending within Carrier i-Vu BAS and other BACnet/Modbus environments to ensure calibrated values are correctly mapped to your sequences of operation.

Our calibration workflow

• Discovery: Review site drawings, sequences, alarm history, and prior commissioning reports.
• Baseline: Capture current readings, compare with reference standards, identify drift and noise.
• Calibrate: Apply NIST-traceable standards, adjust offsets, re-range devices, and recheck stability.
• Controls verification: Confirm BAS point mapping, scaling, and units; validate resets and economizer logic.
• Functional tests: Prove performance under realistic operating conditions (occupied/unoccupied, load steps).
• Reporting: Deliver before/after data, certificates, and recommendations aligned with ASHRAE 55/62.1 and Title 24.

Where appropriate, we fine-tune PID loops, tighten alarm thresholds, and update trend logs so your facility team can catch drift early.

Compliance and documentation

Our reports support California Title 24 compliance efforts and align with ASHRAE 55 (thermal comfort) and ASHRAE 62.1 (ventilation) guidance. We provide calibration certificates, instrument traceability, and digital records suitable for audits, commissioning, and continuous monitoring programs.

Industries and facilities we serve

• Office campuses and mixed-use properties
• Healthcare and labs (with coordinated IAQ validation)
• Manufacturing and clean process areas
• Education and municipal buildings
• Hospitality, retail, and entertainment venues
• Data rooms and mission-critical spaces

From single RTUs to multi-building campuses, we scale our team and tools to meet your scope without slowing operations.

When to recalibrate

• Annually for most spaces; semiannually for critical environments
• After sensor replacements, major service, or control upgrades
• When alarms increase, energy use spikes, or comfort complaints rise
• Following construction, filter changes with significant pressure shifts, or outdoor air strategy changes

Proactive calibration plans include trend reviews and drift alerts so you can act before issues surface.

Service coverage and response

Based in Greater Los Angeles, we proudly serve the City of Orange and all of Orange County, plus Los Angeles County, Ventura County, and Western Riverside County. Need fast help? Ask about same-week scheduling and emergency calibration for critical spaces.

What to expect on site

• Pre-job safety and coordination meeting with your facilities and controls teams
• Tagged devices and clean, documented adjustments
• Live verification in your BAS (including i-Vu) with the operator present
• Actionable closeout report with prioritized recommendations

Every step is designed to be transparent, safe, and repeatable—so your team can maintain results long after we leave.
