• Evaporator Coil: Located inside, this coil absorbs heat from the air, cooling it.
• Refrigerant: A special fluid that absorbs and releases heat, circulating through the system.
• Expansion Valve/Metering Device: Regulates the flow of refrigerant.
• Blower Motor: Circulates air over the evaporator coil to cool the air.
• Ductwork: The system of pipes that distributes the cooled air throughout your home.
• Thermostat: Controls the temperature settings and turns the AC on and off.

     • Make sure the thermostat is set to "cool" and the temperature is set lower than the current room temperature.
     • Check the batteries in your thermostat and replace them if needed.
     • Ensure the thermostat is properly wired and functioning.
   • Inspect the Unit:
     • Look for any obvious signs of damage or obstructions.

   • Check the Condenser Coil: Make sure the outdoor unit’s condenser coil is clean and free of debris like leaves, dirt, or grass clippings.
   • Check for Refrigerant Leaks: Low refrigerant levels can cause the unit to blow warm air. This requires a professional to diagnose and repair.
   • Check the Compressor: If the compressor is not running, the unit won’t cool. This is a more serious problem and may require a professional.

   • Check the Air Filter: A dirty filter reduces airflow and cooling efficiency.
   • Check the Ductwork: Leaks in the ductwork can cause cooled air to escape before reaching your rooms. Seal any leaks you find.
   • Check the Refrigerant Levels: Low refrigerant can reduce cooling performance. A professional must check and recharge the refrigerant.
   • Inspect the Blower Motor: A failing blower motor may not circulate air properly.
