Step 1: Shutting off the Air Conditioning Unit
The first step in resetting your air conditioning unit is to ensure that it is properly shut off. This will allow the system to reset and start fresh. Here’s how you can do it:
- Locate the main power switch for your air conditioning unit. This switch is typically found near the outdoor condenser unit or in the utility room.
- Flip the switch to the “off” position. This will completely shut off the power supply to the unit.
- If your air conditioning unit has a separate circuit breaker, you can also turn it off to ensure that there is no power going to the unit.
Shutting off the air conditioning unit is an important safety precaution before attempting any maintenance or troubleshooting steps. By cutting off the power supply, you reduce the risk of electric shock or other accidents.
Once you have shut off the unit, it’s important to wait for a few minutes before moving on to the next step. This allows the system to fully power down and reset itself.
Now that the air conditioning unit is properly shut off, it’s time to move on to the next step: resetting the circuit breaker.
Step 2: Resetting the Circuit Breaker
Resetting the circuit breaker for your air conditioning unit is a crucial step in the reset process. Often, a tripped circuit breaker can cause the unit to malfunction or stop working altogether. Follow these steps to reset the circuit breaker:
- Locate your home’s main electrical panel or circuit breaker box. This is usually found in the basement, utility room, or garage.
- Open the panel or box to reveal the circuit breakers.
- Inspect the breakers to identify any that may have tripped. Look for breakers that are in the “off” position or that are not aligned with the others.
- If you find a tripped breaker, switch it to the “off” position first, and then back to the “on” position. This will reset the breaker.
- If the breaker trips immediately after resetting it, there may be an electrical issue that needs to be addressed by a licensed electrician.
Resetting the circuit breaker restores the electrical flow to your air conditioning unit. It is a simple yet effective troubleshooting step that can often resolve power-related issues.
Once you have reset the circuit breaker, give your air conditioning unit a few minutes to power back on and stabilize. If the circuit breaker trips repeatedly, it’s crucial to consult with an electrician or HVAC professional to identify and fix any underlying electrical problems.
Now that the circuit breaker is reset, it’s time to move on to the next step: resetting the thermostat.
Step 3: Resetting the Thermostat
Resetting the thermostat of your air conditioning unit can often resolve issues related to temperature control or programming errors. Follow these steps to reset your thermostat:
- Locate your thermostat on the wall. It is typically found in a central area of your home, such as the living room or hallway.
- Take off the cover of the thermostat to reveal the wiring and buttons.
- Look for a small button or switch labeled “Reset” or “Restart”. This button is usually located near the display screen or on the back of the thermostat.
- Press and hold the “Reset” or “Restart” button for a few seconds until you see the display screen flash or the thermostat indicators reset.
- Release the button and wait for a few seconds to allow the thermostat to complete the reset process.
Resetting the thermostat clears any errors or programming glitches that may be affecting the proper functioning of your air conditioning unit. It helps ensure that the thermostat is properly calibrated and ready to control the temperature as desired.
After resetting the thermostat, you may need to reprogram any desired temperature settings or schedules. Refer to your thermostat’s user manual for instructions on programming and setting preferences.
Once you have reset and programmed the thermostat, allow the air conditioning unit a few minutes to respond to the new settings. If you continue to experience issues or if the unit fails to turn on, it may be necessary to move on to the next step: checking for blockages or obstructions.
Step 4: Checking for Blockages or Obstructions
Blockages or obstructions in your air conditioning system can restrict airflow and lead to poor performance or even system shutdown. It’s essential to check for and remove any potential blockages to ensure optimal operation. Here’s how you can do it:
- Start by inspecting the outdoor condenser unit. Clear any debris such as leaves, twigs, or grass that may have accumulated around the unit. Use a brush or a soft cloth to gently remove any dirt or dust that may be blocking the airflow through the unit’s intake vents.
- Next, check the indoor air conditioning unit. Remove any objects that may be blocking the supply or return vents, such as furniture, rugs, or curtains. Ensure that all vents are unobstructed and open.
- Inspect the air ducts for any blockages or obstructions. Look for signs of dirt, dust, or debris that may have accumulated inside the ductwork. If necessary, contact a professional duct cleaning service to clean the air ducts thoroughly.
- Check the air filters of your air conditioning system. Dirty or clogged filters can significantly impede airflow. If the filters are dirty, clean or replace them according to the manufacturer’s instructions.
Clearing blockages and obstructions allows for proper airflow and ventilation in your air conditioning system. By ensuring unobstructed pathways, you can improve the efficiency and performance of your unit.
Once you have checked for and removed any blockages or obstructions, it’s time to move on to the next step: cleaning or replacing the air filter.

Step 5: Cleaning or Replacing the Air Filter
The air filter in your air conditioning unit plays a crucial role in maintaining good indoor air quality and optimizing system performance. Over time, the air filter can become clogged with dirt, dust, and other particles, restricting airflow and reducing efficiency. Cleaning or replacing the air filter is an important step in resetting your air conditioning unit. Here’s what you need to do:
- Locate the air filter. In most cases, it is located behind a removable panel near the air handler or furnace.
- Remove the filter from its housing. Pay attention to the direction of airflow indicated on the filter frame; this should be followed when installing a new filter.
- If the filter is washable or reusable, rinse it gently with water to remove dirt and debris. Allow it to dry thoroughly before reinstalling.
- If the filter is not washable or reusable, replace it with a new filter of the same size and type. Make sure to choose a filter with the appropriate MERV (Minimum Efficiency Reporting Value) rating for your specific air conditioning system.
- Reinstall the clean or new air filter, ensuring it is properly seated and the direction of airflow is correct.
Cleaning or replacing the air filter can significantly improve indoor air quality, increase energy efficiency, and prolong the lifespan of your air conditioning unit. It’s recommended to clean or replace the filter every one to three months, depending on usage and the environment.
Once the air filter is clean or replaced, allow the air conditioning unit a few minutes to adjust to the improved airflow. If you continue to experience issues or if the unit doesn’t function properly, it may be necessary to contact a professional technician for further assistance.
Now that you have cleaned or replaced the air filter, let’s move on to the final step: considering contacting a professional technician.
Step 6: Contacting a Professional Technician
If you have followed the previous steps and your air conditioning unit is still not functioning properly, it’s time to consider calling a professional technician.
