Is There a Reset Button on My AC Unit? DIY FAQs
Quick Summary: Yes, most air conditioners have a reset button, typically located on the outdoor unit or behind the service panel. Pressing this button or resetting your circuit breaker can resolve minor AC issues like poor cooling after a power outage or electrical surge. However, frequent resets may point to deeper problems like a refrigerant leak, faulty thermostat, or mechanical issues. Regular maintenance, checking your power supply, and monitoring thermostat settings can prevent future issues. For persistent problems or electrical issues, it’s best to call a professional.

When starting DIY projects, you may have a lot of questions about the equipment you are working with, and those questions can lead to more questions. Is there a rest button on my ac unit? Outside or inside? How do I reset my air conditioner? The answers to these types of questions can help your DIY project go smoothly and safely. Luckily, trained professionals at Same Day Heating, Cooling, Plumbing are here to help! We have crafted a guide to some of the most common DIY FAQs, to help you with your next HVAC DIY project.
Reset Button on AC Unit – Outside
On most AC units, you will be able to find the reset button on the exterior of the condenser unit. This is the portion of your system that you will find outdoors around your house. You should be able to spot this easily, as it is often a relatively large red button. If you can’t seem to find the button on the exterior of the unit, it is possible that it could be inside the condenser behind the service panel. Be careful though, you will want to shut down the system before you look inside the condenser.
This can be helpful for any DIY project that requires you to reset your air conditioner at the beginning or end of it.
How Often Should I Replace My AC Filters
One of the reasons you may need to reset your AC unit is because it is running slowly. A main factor that could be harming the efficiency of your system is dirty AC filters. So, how often should you change the filters on your AC unit? We recommend changing or cleaning them every 3 months or so. This will help your system run as smooth as possible.

When and Why to Use the Reset Button
Resetting your air conditioning unit can solve several common issues—including after a sudden disconnection, power surge, or power outage. It can also help when your unit is not responding to thermostat settings or is blowing warm air despite being set to cool. These symptoms might indicate a faulty thermostat, a tripped protection circuit breaker, or an issue within the electrical supply.
However, frequent resets can point to deeper mechanical issues, like a refrigerant leak, ice buildup, or malfunctioning sensors. If you find yourself pressing that reset button often, it’s time to schedule an AC repair to prevent extensive repairs or higher utility bills down the road.
Resetting Through the Breaker Panel
If there isn’t visibly a reset button on ac unit, or if pressing it doesn’t work, your next step is the breaker panel. Locate the circuit breaker box and flip the breaker connected to your air conditioning system off. Wait about 60 seconds before turning it back on. This method resets the system’s electrical connection, allowing the internal components to start fresh and potentially resolving the issue.
Keep in mind, if the breaker immediately trips again after resetting, this could signal a serious electrical issue. In that case, emergency repairs by a professional technician are recommended to avoid further frustrating experiences or safety hazards.
Other Tips for Preventing AC Problems
In addition to knowing where your AC reset button is, there are a few best practices to keep your system running efficiently:
- Regular Maintenance: Routine preventive maintenance can help prevent major issues before they happen. A technician can inspect your electrical components, clean coils, and check refrigerant levels.
- Check the Isolator Switch: Some outdoor units also have an isolator switch, which may look like a fuse or breaker near the condenser. Make sure this hasn’t been turned off accidentally.
- Inspect the Power Cord: If your entire unit isn’t turning on, double-check the power cord and electrical connection for wear, disconnection, or damage.
- Monitor Energy Bills: A sudden spike in energy bills could indicate that your system is working harder than it should be—often a sign of hidden problems that a simple reset won’t solve.
When to Call a Professional
DIY troubleshooting is great for minor issues, but if your AC continues to trip the AC breaker, shut down unexpectedly, or show signs of serious electrical problems, it’s time to schedule service. Trained technicians can diagnose deeper system failures, repair electrical supply problems, and prevent costly emergency repairs. At Same Day Heating, Cooling, Plumbing, we offer prompt, reliable service that keeps your air conditioning running smoothly—no guesswork required.
How Can I Fix Uneven Temperatures Throughout My Home?
Have you ever noticed that different areas of your home feel warmer or cooler? Why does this happen and how can you fix it? The most likely reason that you would notice this is because of poor insulation throughout your home. The best thing you can do for this is to checkout your windows. If a certain window lets a lot of sun in, occasionally cover it with a drape. Also, be sure to make sure the window liners are attached properly and not broken.
This should help with your uneven temperature problem. Cleaning or replacing the air filters as mentioned above, can also be a big help to this problem.
