Eastvale HVAC Electrical and Thermostat Diagnosis

Electrical Component Inspection

Technicians opened the HVAC panel to examine the circuit board, relays, and wiring. A clamp meter measured current flow on live circuits, confirming proper operation without guessing at hidden issues common in older Eastvale units.

Thermal Imaging of Ceiling Vents

Thermal camera scans of ceiling air vents revealed temperature patterns across the ductwork. This non-invasive check identified uneven airflow or insulation gaps that reduce cooling efficiency during peak summer heat in Southern California.

Thermostat and System Check

Two Honeywell thermostats were evaluated, one reading 81F with a note above it. Readings helped verify whether the system was maintaining setpoints or cycling incorrectly, a frequent concern for Eastvale homes facing prolonged high temperatures.
