Step-by-step diagnostic approach

A systematic diagnostic approach separates quick fixes from deeper mechanical or refrigerant problems. Green Head Heating technicians use a layered process that balances thoroughness with efficiency.

1. Initial interview and symptom review

• Gather detailed information: when the issue started, patterns, any recent power events, and whether the unit was installed or serviced recently.

1. Visual inspection

• Check indoor and outdoor heads for obvious damage, blocked vents, filter condition, and signs of corrosion or oil stains that indicate leaks.

1. Electrical safety checks

• Verify correct voltage at the unit, inspect breakers and fuses, and examine wiring and terminal connections for heat discoloration or loose fittings.

1. System control and communication tests

• Check remote control, wall controller, and control board LEDs for diagnostic codes. Confirm the indoor and outdoor units are communicating properly.

1. Airflow and mechanical inspection

• Measure supply and return airflow, inspect fan motors and blades, and test fan speeds and motor currents to see if the blower is underpowered or mechanically restricted.

1. Refrigerant and pressure testing

• If performance issues suggest refrigerant problems, technicians use approved gauges and leak detection tools to measure system pressures, check superheat and subcooling, and locate leaks if present.

1. Component function tests

• Test compressors, expansion devices, reversing valves on heat pump systems, and capacitors. Run compressor amperage and temperature checks to identify failing components.

1. Condensate and drain inspection

• Verify proper slope, check for clogs, and inspect the condensate pan for damage or overflow conditions.

1. Final system run and verification

• After any repair or adjustment, run the system to verify temperature split, airflow, pressure stability, and absence of abnormal sounds or error codes.
