Our Compressor Troubleshooting Process

Initial Inspection
We begin with a visual and operational check to identify obvious signs of wear, leaks, electrical damage, or mechanical failure.

Electrical Testing
We use diagnostic tools to check:

• Motor windings and insulation resistance

• Voltage, current, and phase balance

• Capacitors, relays, and contactors

• Control board signals and wiring integrity

Mechanical Assessment
We inspect:

• Bearings, pistons, or scroll elements

• Shaft alignment and motor rotation

• Mounting integrity and compressor vibration

• Oil level and condition

Refrigerant System Evaluation
We verify:

• Suction and discharge pressure levels

• Superheat and subcooling readings

• Proper refrigerant flow and charge

• Expansion valve and sensor performance
