How Do I Reset My Air Conditioner?


With Florida’s intense heat, your air conditioner is essential for keeping your home safe and comfortable. However, like any electronic device, air conditioners can sometimes malfunction or stop working altogether. Before you panic and call a professional, there’s a simple solution that might just save the day: resetting your air conditioner. In this blog post, our HVAC experts at Iceberg Home Services explain reasons to reset your air conditioner and provide a step-by-step guide on how to do it.

Why You Might Need To Reset Your Air Conditioner

Resetting your air conditioner can address a variety of issues, such as:

  • Power outages: A power surge or outage can cause your AC unit to trip its internal safety switch, preventing it from turning on.
  • Thermostat issues: Sometimes, your thermostat might not communicate properly with your AC unit, requiring a reset to re-establish the connection.
  • Unresponsive unit: If your air conditioner is not responding to the thermostat settings or is blowing warm air, a reset might help restore its normal function.
  • Error codes: Modern air conditioners can display error codes to indicate specific issues. Resetting the unit can sometimes clear these codes and resolve the problem.

Step-by-Step Guide to Resetting Your Air Conditioner

If you find yourself needing to reset your air conditioner, follow these steps:

Step 1: Turn Off Your Air Conditioner

First, make sure your air conditioner is turned off. Locate the thermostat and set it to the “Off” position. This step ensures that no power is being supplied to the unit during the reset process.

Step 2: Locate the Circuit Breaker

Find the circuit breaker panel in your home. It’s usually located in a utility room, basement, or garage. The panel contains various switches that control the electrical supply to different parts of your home, including your air conditioner.

Step 3: Turn Off the Circuit Breaker

Locate the switch that controls the power supply to your air conditioner. It is usually labeled “AC” or “Air Conditioner.” Flip this switch to the “Off” position to cut off the power supply to your AC unit. Leave it off for about five minutes to ensure all residual power is drained from the system.

Step 4: Turn the Circuit Breaker Back On

After waiting for five minutes, flip the circuit breaker switch back to the “On” position. This step restores the power supply to your air conditioner.

Step 5: Reset the Air Conditioner at the Unit

Some air conditioners have a reset button located on the unit itself. This button is usually red and may be found on the control panel or near the power cord. Press and hold the reset button for about three to five seconds, then release it. If your unit doesn’t have a reset button, you can skip this step.

Step 6: Turn On Your Air Conditioner

Go back to the thermostat and set it to your desired temperature. Turn the thermostat to the “Cool” position and wait for the air conditioner to start running. It may take a few minutes for the system to fully reboot and begin cooling your home.

Step 7: Monitor Your Air Conditioner

Observe your air conditioner for the next few hours to ensure it’s working properly. If the unit still doesn’t function correctly, you may need to consult a professional HVAC technician to diagnose and repair the issue.

When To Call a Professional

If you’ve tried resetting your air conditioner, but the problem still persists, there are a few more things you can try before reaching out to an HVAC company. Double-check your thermostat settings to ensure everything is set correctly. You should also check your air filters and clean or replace them if necessary. If these steps don’t solve the issue, you should inspect the outdoor unit of your AC to see if there are any visible signs of refrigerant leaks, as low refrigerant will cause your AC to perform poorly.

If you do suspect a refrigerant leak or you are unable to identify the cause of your air conditioning issue, then it’s time to call a professional. At Iceberg Home Services, our HVAC technicians are all highly trained and experienced, so we can diagnose your AC problem and repair it quickly.
