How Do I Reset My Air Conditioner?
If your air conditioner suddenly stops working, starts blowing warm air, or isn’t responding to thermostat changes, a simple reset might be all it needs. At Integrity Air Solutions, we often help homeowners troubleshoot before jumping to costly repairs—and resetting your AC is one of the first steps worth trying.
When Should You Reset Your AC?
You should consider resetting your air conditioner if it won’t turn on, starts blowing warm air, the thermostat becomes unresponsive, or if the system shuts off unexpectedly after a power outage. These minor disruptions often interfere with the unit’s control board, and a reset can clear the error and restore normal operation.
How to Reset Your Air Conditioner
Start by turning off your thermostat completely. This prevents the system from trying to engage while you perform the reset.
Next, locate the power supply for your AC unit. This is typically found in your home’s main electrical panel, where the circuit breakers are located, or near the outdoor condenser unit if there’s a dedicated disconnect switch.
Turn off the power to your air conditioner. If you're using the circuit breaker, flip it to the "off" position. If your unit has an external disconnect box, turn that switch off as well. This ensures the system is fully shut down before resetting.
Wait for one to five minutes to allow any residual electrical charge to clear. This pause is essential—it gives the internal controls a moment to reset completely.
Finally, turn the power back on by flipping the breaker or disconnect switch to the “on” position. Head back to your thermostat and set it to your desired temperature. Within a few minutes, your air conditioner should start running again and blowing cool air.
Key Takeaways
Resetting your AC is useful after power outages or when the thermostat seems unresponsive. Always be sure to turn off power before performing a reset, and give the system a few moments before restoring electricity. After resetting, double-check your thermostat settings. If your system still doesn't function properly after these steps, it’s best to call in a professional.
