• Refrigerant: A special fluid that absorbs and releases heat, circulating through the system.
• Expansion Valve: Controls the flow of refrigerant into the evaporator coil.

   • Check the Power Supply: Ensure the unit is plugged in and the circuit breaker hasn’t tripped. Check the disconnect box near the outdoor unit.
   • Thermostat Settings: Verify that the thermostat is set to "cool" and the desired temperature is lower than the current room temperature. Check the batteries in the thermostat.
   • Inspect the Condensate Drain: A clogged drain line can sometimes trigger a safety switch that prevents the unit from turning on.

   • Thermostat Settings: Double-check the thermostat settings to ensure it’s set to "cool" and the fan is set to "auto."
   • Air Filter: A clogged air filter restricts airflow, reducing cooling efficiency. Replace the filter regularly (usually every 1-3 months).
   • Outdoor Unit Obstructions: Clear away any debris, such as leaves, grass clippings, or bushes, that may be blocking airflow around the outdoor unit.
   • Refrigerant Leaks: Low refrigerant levels can cause the AC to blow warm air. This requires professional attention to locate and repair the leak and recharge the system.
   • Compressor Failure: If the compressor is not working, the AC won’t cool. This is a serious problem that necessitates a professional repair or replacement.

   • Air Filter: A dirty air filter can reduce airflow and cooling capacity.
   • Refrigerant Leaks: Low refrigerant levels can cause the AC to struggle to cool your home.
   • Dirty Coils: Both the evaporator coil (inside) and the condenser coil (outside) can accumulate dirt and debris, reducing their efficiency. Clean them regularly.
   • Ductwork Leaks: Leaks in the ductwork can cause cooled air to escape before reaching your rooms. Have a professional inspect and seal any leaks.
   • Oversized or Undersized Unit: If your AC unit isn’t the right size for your home, it may not cool effectively. This is something that needs to be addressed by a professional.

   • Frozen Evaporator Coil: If the evaporator coil freezes, it can melt and leak water. This can be caused by low airflow (clogged filter), low refrigerant, or a problem with the blower motor.
   • Condensation: During humid weather, condensation can form on the AC unit. Make sure the unit is properly insulated.
   • Professional Help: If the leak persists, it could be due to a cracked drain pan or other internal damage, requiring professional repair.
