Comprehensive Diagnostic Services

Error Code Diagnosis

Heat pump displaying error codes? We decode manufacturer-specific codes and identify the exact component or system causing the issue.

  • Mitsubishi error codes
  • Daikin fault codes
  • Fujitsu diagnostic codes
  • All major brands supported
Performance Testing

System running but not performing well? We measure actual performance against manufacturer specifications to identify efficiency problems.

  • Temperature differential testing
  • Airflow measurement
  • Refrigerant pressure analysis
  • Electrical current draw testing
Electrical Diagnostics

Intermittent problems or electrical issues? We test all electrical components, circuits, and controls to identify failures.

  • Circuit board testing
  • Capacitor load testing
  • Sensor calibration checks
  • Wiring integrity testing
Refrigerant System Analysis

Cooling or heating capacity problems? We perform detailed refrigerant system analysis to identify leaks, charge issues, or component failures.

  • Refrigerant charge verification
  • Leak detection testing
  • Pressure/temperature analysis
  • Superheat/subcooling measurements

Common Diagnostic Scenarios

System Won't Start

When your heat pump doesn't turn on, we systematically test power supply, thermostat signals, safety switches, and control boards to identify why the system won't start. We don't guess—we test.

Intermittent Operation

Intermittent problems are the hardest to diagnose. We use diagnostic tools and monitoring to catch issues that come and go, identifying loose connections, failing components, or temperature-sensitive failures.

Poor Performance

When your system runs but doesn't heat or cool properly, we measure actual performance against manufacturer specs. This reveals whether the problem is mechanical, electrical, refrigerant-related, or airflow-based.

High Energy Bills

Unexplained increase in electricity costs? We test system efficiency, identify components drawing excessive power, and check for issues causing the system to work harder than necessary.

Our Diagnostic Process

1

Detailed Problem Assessment

We start by understanding your symptoms, when the problem occurs, and any error messages. This guides our diagnostic approach.

2

Systematic Testing

Using professional diagnostic tools, we test components systematically rather than replacing parts randomly. This saves you money and time.

3

Clear Explanation

We explain exactly what's wrong, what caused it, and what repair options you have. No technical jargon—just clear, honest communication.

4

Repair Recommendations

Based on our findings, we provide repair recommendations with transparent pricing. You decide how to proceed—we never pressure you.
