Practical homeowner troubleshooting before a technician arrives

Safe, simple checks can sometimes resolve issues or provide useful information for the technician. These steps are intended for homeowners and should be performed only if it is safe to do so:

• Check power and breakers
  
  • Confirm the unit is receiving power and the circuit breaker or disconnect switch has not tripped. Reset only once and monitor.
• Inspect filters and indoor head
  
  • Clean or replace washable filters. Remove obvious debris from the indoor head louvers. Dirty filters often reduce airflow and cause icing.
• Check remote control and thermostat settings
  
  • Confirm mode, temperature setpoint, fan settings, and that the remote batteries are functional.
• Look for error codes and note behavior
  
  • If the indoor display shows an error code or flashing lights, write down the code and the pattern of flashes. This helps speed diagnosis.
• Clear outdoor unit area
  
  • Remove leaves, grass clippings, and clutter around the outdoor condenser to ensure proper airflow.
• Listen and observe
  
  • Note unusual noises, hissing, or vibrations and check for visible oil stains that hint at refrigerant leaks.

What not to do:

• Do not attempt to open electrical panels or internal components unless qualified.
• Avoid adding refrigerant yourself. Incorrect charging or mixing refrigerant types can cause severe equipment damage and is illegal for non-certified technicians.
• Do not attempt brazing or refrigerant repairs. These require certified technicians and specialized equipment.
