High-Efficiency 5-Ton Heat Pump Diagnostic & Motor Replacement
Diagnostic and component overhaul on a 5-ton Trane variable-speed heat pump during peak 112°F summer temperatures.
The Diagnostic Challenge
The home's second floor had lost cooling completely; the blower was unresponsive and the digital thermostat displayed communication failure code ERR-82.
Technical Solution & OEM Parts
Replaced an overheated ECM 2.3 blower control module, upgraded the dual-run capacitor to a heavy-duty AmRad US-manufactured component, and cleaned the choked outdoor coil with biodegradable foaming wash.
Verified Field Result
Airflow CFM restored to 1850 CFM with a crisp 20°F temperature drop across the evaporator coil, restoring comfortable 72°F indoor temps.

"Our high-efficiency washer wouldn't drain and was flashing an OE code with a tub full of water. Technician replaced the seized pump on the spot. Very clean work and friendly service."
"When our AC went down during 110-degree heat in Paradise Valley, they came out the same afternoon. Replaced the capacitor and contactor in under 45 minutes. Truly saved our family."
