Our repair trucks carry the common parts that account for the majority of West Valley AC failures: run capacitors in standard sizes, contactors, universal condenser fan motors, common blower motors, thermostat wire, float switches, condensate drain line components, and refrigerant for both R-410A and R-454B systems. We stock from major distributors including Carrier, Trane, Lennox, Goodman, Rheem, and Bryant parts catalogs. Brand-specific parts that are not on the truck are typically next-day from supplier stock.
Diagnostics use digital manifold gauges, clamp meters for current measurement, multimeters for voltage and resistance checks, electronic refrigerant leak detectors, and infrared thermometers for measuring temperature splits across the coil. Refrigerant work follows EPA Section 608 requirements. Our techs hold EPA universal certification and are trained on both R-410A and R-454B handling. All refrigerant transactions are documented.
We follow manufacturer service procedures for the equipment we repair. That means measuring superheat and subcooling on a refrigerant adjustment, checking static pressure when there is an airflow complaint, and pulling the manufacturer's service manual when an unfamiliar issue comes up. We do not guess at issues we have not seen before.
