Your home’s HVAC system works hard to keep you comfortable year-round. But just like any other piece of equipment, it can occasionally run into issues—especially after a power surge, outage, or overload. One common problem homeowners face is a tripped HVAC system. When that happens, knowing how to safely reset it can save you time, money, and unnecessary stress.
Here’s how to do it the right way.
1. Identify Why Your HVAC System Tripped
Before you reset your HVAC system, find out why it tripped. Common reasons include:
- Power surges or lightning strikes
- Overloaded circuits from running multiple high-power appliances
- Dirty air filters are restricting airflow.
- Low refrigerant levels are causing the system to overheat.
- Faulty wiring or damaged components
If your breaker keeps tripping, you have a deeper issue. Don’t just reset it—call a licensed HVAC technician for an inspection.
2. Turn Off Your HVAC System Completely
Switch off your HVAC at the thermostat, then turn off its breaker at the electrical panel. This prevents unexpected restarts and keeps you safe while working on the unit.
Wait 30 seconds before moving on to give the system time to power down.
3. Check the Air Filter and Outdoor Unit
Check the air filter and replace it if it’s dirty to prevent trips.
Inspect the outdoor unit and clear away any debris to maintain airflow.
4. Reset the Circuit Breaker
At the panel, flip the HVAC breaker off, then on. Feel for a click to ensure reset.
If the breaker trips again, stop. You may have an electrical or compressor issue and need professional help to avoid damage or fire.
5. Restart the HVAC System
Turn the system back on at the thermostat and set your preferred temperature. It may take a few minutes to start.
If your system runs normally, it’s reset. If not, call a professional.
6. Prevent Future Trips
To reduce the likelihood of your HVAC tripping again:
- Replace air filters regularly (every 1–3 months)
- Keep vents and outdoor units clear.
- Avoid overloading electrical circuits.
- Have your HVAC serviced annually.
Simple maintenance helps your system run safely and smoothly.
