Pressure and leak detection
Electronic sniffing and nitrogen pressure decay tests isolate microscopic pinhole leaks across copper evaporator coils and thermal expansion valves before charging.
Capacitor and contactor testing
Microfarad capacitance meters verify motor run capacitors while contactor contact points are checked for pitting, preventing compressor motor burnout during heatwaves.
Furnace diagnostics
Hot surface ignition and flame sensor service
Microamp flame signal verification and silicon nitride igniter resistance testing ensure reliable furnace firing cycles in freezing winter weather without intermittent lockouts.
ECM blower motor and duct static balancing
Static pressure manometers check return plenums and variable-speed blower modules to eliminate restricted airflow, cold spots, and overheating burner chambers.
Heat exchanger and burner safety inspection
Combustion gas analysis and micro-camera inspection detect hairline fractures across heat exchanger cells, protecting indoor air supply from toxic carbon monoxide.
