While our air conditioning systems often work well this time of year, they can still develop efficiency or performance problems. When cooling issues occur, many homes or business owners choose to reset their air conditioners as a first solution for getting them to work properly again. However, since most AC unit models and their ages differ, knowing how to reset them isn’t always a uniform or straightforward process.

Think of A/C units like cars. Their performance can vary based on age, size, parts, and how they were built.

Luckily, resetting an AC unit typically takes a few simple steps that generally can be applied across the board.

What are the basic steps to reset an air conditioner?

The basic HVAC troubleshooting steps usually include turning off the thermostat, shutting off the unit, turning off the breaker, waiting briefly, restoring power, and checking if the system starts cooling again.

Step 1 – Turn the whole unit off.

Sounds simple enough, right? The first step is to power down the air conditioner. Start by ensuring the thermostat is in the “off” position. After this, turn off your air conditioner, typically by finding the shutoff switch on your AC unit. It should be stressed that shutting off your A/C unit is a crucial safety measure that you must always follow. If you skip this step, an electrical shock or other problems could occur.

Step 2 – Locate the Circuit Breaker.

Your next step is to find the circuit breaker box for your air conditioner system. This box is usually located in a basement, closet, crawl space, or on the side of your home. Look for a mounted metal breaker box! Once you’ve located it, turn off the switch that is connected to your A/C unit. Before you do this, let everyone else in the house know that you’re resetting the breakers.

If you notice a tripped AC breaker, reset it only once. If it trips again, stop and contact a professional instead of continuing to reset air conditioner controls on your own.

Step 3 – Wait…

Once you’ve turned the switch off that runs to your AC unit from the circuit breaker, wait for a minimum of 1 minute (or longer if you can).

Step 4 – Power “On”

After the time is up, flip the switch back to “on.” Now, wait an additional minute, and give the unit the necessary time to power itself back up adequately. wait, go back to the thermostat and turn the A/C unit back on from there.

This thermostat AC reset step helps the system restart in the correct order.

Step 5 – Check to see if it’s working.

Give the thermostat a few minutes to re-adjust and start up again after you set your desired temperature. If cool, consistent air starts to blow from the vents, this is all the confirmation you need that the process has been a success.

What does an AC reset button do?

An AC reset button restarts the system without requiring you to manually cycle the breaker. Not every system has one, but it can make the reset process faster on some newer models.

Got a Reset Button?

Some more modern units have a dedicated reset button that does this whole process for you. It’s likely located on your outdoor unit and will be a large red button you can’t miss. Simply pressing this button may reset the system, depending on the model.

When should you not try resetting your AC unit?

Do not attempt an AC reset if you see exposed wiring, repeated breaker trips, damage at the electrical panel, or anything that makes the process feel unsafe.

Warning signs: Do not attempt reset!

In the event of an emergency where your breaker is constantly tripping, the breaker panel is exposed, or wires are exposed at the breaker, do not attempt any of these reset processes yourself and consult a professional. Furthermore, if the manual reset process makes you uncomfortable, a professional will be more than willing to perform it for you. There’s no shame in asking!
