Summer is in full swing, and the last thing you want to deal with is a malfunctioning air conditioner. When your AC unit suddenly stops running, it can be frustrating and inconvenient, especially during the hot and humid months. However, before you start to panic, there are a few troubleshooting steps you can take to potentially identify and fix the issue. In this guide, we’ll discuss the common reasons why air conditioners quit running and what you can do to address the problem.
Check the Thermostat
One of the first things to check when your air conditioner stops running is the thermostat. Ensure that it is set to cool and that the temperature setting is lower than the current room temperature. If the thermostat is not functioning properly, it may cause the AC unit to not start or stop running unexpectedly. Additionally, check the batteries in the thermostat to make sure they are not dead and replace them if needed.
Inspect the Circuit Breaker
If your air conditioner has suddenly stopped running, it could be due to a tripped circuit breaker. Head to your electrical panel and check if the breaker for the AC unit has tripped. If it has, reset the breaker and see if that resolves the issue. Keep in mind that a tripped circuit breaker could indicate a larger electrical problem, so if it continues to happen, it’s best to consult with a professional electrician.
Examine the Air Filter
A dirty or clogged air filter can restrict airflow and cause the AC unit to stop running efficiently or even overheat. Check the air filter and if it’s dirty, replace it with a new one. It’s recommended to inspect and change the air filter every 1-3 months to ensure proper airflow and system performance.
Verify the Outdoor Unit
Another potential reason for your air conditioner quitting is an issue with the outdoor unit. Take a look at the outdoor condenser and ensure that it’s not blocked by debris such as leaves, dirt, or overgrown vegetation. Clear any obstructions around the unit and make sure it has proper clearance for airflow. Additionally, check if the outdoor unit’s fan is spinning when the AC is turned on. If the fan is not running, there may be a mechanical or electrical issue that requires professional attention.
Call a Professional Technician
If you’ve gone through the troubleshooting steps and your air conditioner still isn’t running, it’s time to call a professional HVAC technician. They have the expertise and tools to diagnose the problem accurately and safely. Attempting to fix complex AC issues without the proper knowledge can lead to further damage and safety hazards.
When scheduling an appointment with an HVAC technician, be sure to describe the issue in detail and provide any relevant information about your AC unit, such as the make, model, and any unusual noises or smells you may have noticed before it stopped running. This information can help the technician prepare and potentially expedite the repair process.
