As the scorching summer heat sets in, the last thing you want is for your air conditioning system to suddenly stop blowing cold air. It can be frustrating and uncomfortable, especially during those sweltering days. However, before you start to panic, there are a few steps you can take to troubleshoot the issue and potentially get your AC back on track. In this blog post, we’ll guide you through the necessary steps to address this problem. We highly recommend choosing Fannon & Sons Heating Cooling for your AC repair in Knoxville, TN.

• Check the Thermostat: The first thing to do when your AC stops blowing cold air is to check your thermostat. Ensure that it is set to the appropriate temperature and cooling mode. The settings were accidentally changed, causing warm air to blow instead of cold. Adjust the thermostat to a temperature lower than the current room temperature and see if the air starts to cool down.
  
  
• Replace the Air Filter: A clogged or dirty air filter can significantly restrict airflow, leading to a decrease in cooling efficiency. Locate the air filter, usually found near the air handler or in the return air duct, and inspect it for dirt and debris. If it appears dirty, it’s time to replace it with a new one. This simple step can improve air circulation and restore the cold airflow in your home.
  
  
• Check the Circuit Breaker: A tripped circuit breaker can disrupt the power supply to your AC unit, resulting in warm air blowing through the vents. Locate your circuit breaker panel and check if any breakers are in the “off” position. If you find a tripped breaker, reset it and observe if that resolves the issue. However, if the breaker continues to trip, it’s best to seek professional assistance.
  
  
• Clean the Outdoor Unit: Over time, the outdoor unit of your AC system can accumulate dirt, leaves, and debris, obstructing airflow and hindering cooling efficiency. Safely turn off the power to the unit and carefully remove any visible debris. You can use a gentle stream of water to hose down the unit and remove dirt and grime. Remember to avoid using excessive force to prevent causing damage.
  
  
• Inspect the Air Ducts: Leaky or poorly insulated air ducts can cause cooled air to escape before reaching your living spaces. Inspect the air ducts for any visible leaks or gaps. If you discover any, consider sealing them using specialized duct sealant. Alternatively, you can seek assistance from a professional HVAC technician who can provide expert advice and address any ductwork issues.
