Inspection and diagnostic process that protects performance

A professional inspection starts with a system history and current symptom description, then proceeds through structured diagnostic steps. Green Head Heating technicians use industry-standard diagnostic tools and procedures tailored to mini-splits:

1. Visual inspection of indoor and outdoor units for signs of corrosion, animal or plant intrusion, damaged panels, and drainage issues.
2. Confirm electrical integrity: checking breakers, disconnects, contactors, capacitors, and wiring for safe operation.
3. Measure operating pressures and temperatures to determine refrigerant charge accuracy and heat exchange efficiency.
4. Verify airflow across indoor coil, measure static pressure where required, and inspect filter and ductless airflow pathways.
5. Review control signals and sensor readings, including thermostats, remote controls, and communication links between indoor and outdoor units.
6. Identify abnormal sounds and trace to mechanical or airflow causes.
7. Provide a written diagnostic report and prioritized recommendations based on safety, efficiency, and urgency.

This diagnostic framework reduces guesswork and helps homeowners make informed decisions about repairs, replacements, and optimization.

Repair approach and parts

When repairs are needed, the approach focuses on lasting solutions, safe practices, and compatibility with existing systems. Common repairs in Maple Valley mini-splits include refrigerant leak repair and recharge, fan motor and capacitor replacement, reversing valve or compressor repairs, and control board replacement.

Parts are selected for compatibility and longevity. For systems covered by manufacturer warranties or enrolled in programs like Mitsubishi Comfort Care, OEM parts and service procedures are used to maintain warranty coverage. Repairs follow EPA guidelines for refrigerant handling and recovery.

Technicians prioritize repairs based on:

• Safety risks such as electrical hazards or refrigerant exposure
• Severity of comfort impact during seasonal extremes
• Potential for further damage if left unaddressed
• Cost-efficient options that extend service life without unnecessary replacement

Preventative maintenance: scheduled care that saves money

Preventative maintenance reduces unexpected failures, improves efficiency, and extends system life. In Maple Valley, a typical preventative schedule includes:
