Eight Reasons Why Your AC Won’t Turn On

1. Thermostat Issues: One of the most common reasons for an AC not turning on is a problem with the thermostat. Check to ensure it’s set to the “cool” setting and the temperature is lower than the current room temperature. You should also replace the batteries if they’re down or check the thermostat circuit breaker if it’s not working.
   
   
2. Dirty or Clogged Air Filter: A dirty or clogged air filter can obstruct airflow and cause your AC to shut off. Changing your air filter at regular intervals is essential to ensure proper airflow. We recommend changing it every month or two, depending on the filter type and the air pollution level in your area.
   
   
3. Frozen Evaporator Coils: If your AC is running but not cooling your home, the evaporator coils may be frozen. A lack of airflow or a low refrigerant level can cause this. Turn off your AC and let the ice melt to fix this issue. Then, check for any airflow obstructions and consider getting a professional to check the refrigerant level.
   
   
4. Malfunctioning Compressor: The compressor is an essential part of your air conditioning unit and is responsible for circulating the refrigerant. If it’s not functioning properly, your AC won’t work. If you suspect a problem with the compressor, it’s best to call a professional for repair.
   
   
5. Electrical Issues: Electrical issues can cause your air conditioner to stop working. Check the circuit breaker and ensure it hasn’t tripped. You should also check the wiring to ensure it’s not frayed or damaged. If you’re uncomfortable checking these things yourself, it’s best to call our technician.
   
   
6. Leaking Refrigerant: A refrigerant leak can cause your AC to stop working and harm the environment. If you want to prevent a leak, it’s essential to schedule an annual AC tune-up in Aransas Pass, TX.
   
   
7. Clogged Drain Line: If the drain line becomes clogged, water can build up and cause your AC to stop working. To fix this issue, locate the drain line and clear any blockages. Call our professional if you cannot identify or remove the blockage.
