Refrigerant and pressure testing

• Use manifold gauges and electronic leak detectors to confirm refrigerant charge and identify leaks
• Measure subcooling and superheat to determine charge accuracy
• Perform vacuum, nitrogen pressure testing, or dye tests if a leak is suspected

Compressor and motor evaluation

• Test starting current, run amps, and motor windings for continuity and insulation
• Listen for abnormal mechanical sounds and measure vibration
• Evaluate compressor protection devices and starting capacitors

Airflow and coil checks

• Measure temperature split across the coil and static pressure in the return and supply
• Check filter condition and airflow obstruction
• Inspect and clean coils if dirty to see if performance returns

Drainage and condensate inspection

• Clear and pressure-test condensate lines
• Verify drain pan condition and float-switch operation
• Confirm correct slope and routing to prevent reoccurrence of drain backups

Diagnostics are reported in plain language so homeowners in Willis understand the issue, the root cause, and the repair options. Visual evidence (photos) and unit fault codes are recorded to document findings.

Common homeowner troubleshooting steps you can safely tryBefore calling a technician, there are a few safe checks any homeowner in Willis can perform. These steps can resolve simple issues and help speed the professional diagnosis.

• Confirm the indoor unit is powered on and set to the correct mode and temperature.
