When the Lights Come Back On: The Critical First Steps to Safely Restart Your HVAC System After Long Island Storm Power Outages
Long Island residents know all too well the devastating impact severe weather can have on their communities. From record rainfall on August 18-19, 2024, that caused flash flooding and home damage to power surges that resulted from utility work and fried appliances in as many as eight homes, the area has faced significant electrical disruptions. When power is finally restored after these events, many homeowners rush to get their HVAC systems running again—but this urgency can lead to costly damage if not done correctly.
Why Your HVAC System Needs Special Attention After Power Restoration
The power surge that comes with electricity being restored can interfere with your air conditioning system, and failing to properly reset it could cause further issues. During a power outage, electrical surges can occur as the power grid stabilizes. These surges can cause fuses to blow or circuit breakers to trip, preventing your AC system from receiving power. Additionally, a power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge.
The Critical 5-Step HVAC Restart Process
Following the proper sequence is essential to prevent damage to your system. Here’s the step-by-step process that HVAC professionals recommend:
Step 1: Turn Off Your System at the Thermostat
Turn off your air conditioner with the thermostat. In this scenario, turning off both you’re A/C with the thermostat will keep your thermostat from connecting with the A/C while you reset your circuit breaker. This prevents the system from attempting to start while you’re performing the reset.
Step 2: Locate and Reset Your Circuit Breakers
If the power outage caused the circuit breaker to trip, you would need to reset it before the air conditioner is able to function properly again. This can be done by finding the circuit box responsible for your HVAC. Once you find it, flip the switch to “off” the breaker panel and then turn it back to the “on” position. The indoor and outdoor units of your cooling system are on individual circuit breakers. When a power surge happens, such as right before an outage, the breakers trip to cut power to the circuit. Sometimes, one breaker or both have tripped.
Step 3: Wait 30 Minutes – This is Critical
After resetting the circuit breaker, it is a good idea to wait at least 30 minutes before turning the air conditioner back on. This gives the system time to properly reset and can help to prevent any potential issues from occurring. Most air conditioning units need about 30 minutes to fully restart. This waiting period allows the system to stabilize, reset the internal circuitry, and prepare to begin cooling again. If you turn the thermostat back on too soon, the system may not work correctly, so it’s important to give the system time to properly reset.
Step 4: Turn On the Circuit Breaker
After the 30-minute waiting period, return to your electrical panel and turn the HVAC circuit breakers back to the “on” position.
Step 5: Restart at the Thermostat
After you’ve waited for 30 minutes, go to the thermostat and set your system back to “on.” Your HVAC should turn back on successfully. Once half an hour has passed, go back to the thermostat and turn your air conditioner back on. If it resets successfully, this usually means your air conditioning system didn’t suffer any damage due to the power outage.
When to Call for Professional Help
If it does not, that may mean that the system was damaged during the storm. If your HVAC system is still struggling to power back up after a power outage, there could be an issue with the capacitor or compressor. Both of these issues do require repairs from a professional HVAC tech. If your system trips the breaker immediately after restart, do NOT reset it until a specialist checks your units.
