Diagnosing problems the right way

Thorough diagnostics separate quick fixes from meaningful, long-term solutions. During a maintenance visit Green Head Heating follows a step-by-step diagnostic approach:

1. System history and symptom gathering

• Ask about when the problem started, what conditions trigger it, and prior service history.

1. Visual inspection and sound assessment

• Look for obvious signs of damage, debris, or water leaks and listen for abnormal noises during operation.

1. Measured testing

• Use gauges and thermometers to measure refrigerant pressures, superheat and subcooling, and temperature split across the coil.

1. Airflow measurement

• Assess airflow across the indoor unit to identify obstructions, motor problems, or duct modifications affecting performance.

1. Electrical testing

• Use multimeters to test voltage, current draw, component resistance, and capacitor microfarad values.

1. Controlled load testing

• Run the system under known conditions to observe how it responds over time and to simulate peak use.

This disciplined approach ensures diagnoses are accurate and that recommended repairs will address root causes rather than symptoms.
