While many people understand that a power surge generally causes power outages in their home, they really don't know what a power surge is or what causes them. Power surges can occur on a large or small scale and can trigger circuit breakers and shut off electrical systems in all or different areas of your home.
What Is a Power Surge?
Most of our homes appliances operate on a specific voltage range, typically between 0 and a peak voltage of 169 volts. During a power surge, the voltage in your home exceeds the peak voltage of 169 volts.
Power surges occur either through an unexpected interruption to the flow of electricity through the grid or when an appliance or device that is plugged in inputs power back into the system instead of drawing it out. Lightning strikes can also be a common cause of power surges. Whether a surge happens on a large or small scale, it can still be potentially damaging to appliances and other electronic devices.
What You Should Do After a Power Surge
- Reset electronics: If a power surge has caused a circuit breaker to trip, then you need to unplug any electrical appliances before resetting your circuit breakers.
- Assess the damage: Check all of your electronic devices and appliances to make sure no damage was done and that they do not pose any risk of fire. If the power surge or outage was caused by lightning, flooding, or a downed power line, then use caution when inspecting your home for any issues or have a professional assess your home for potential damages and other electrical threats.
- Reset your heating and cooling systems: If a triggered circuit breaker has shut down your HVAC system, follow your HVAC owner's manual on how to reset the unit. If you're unsure of the safety of your system, have a professional inspect it and reset it.

A-TEMP Heating, Cooling & Electrical came recommended from a friend who is a current inspector. I've used them for years for furnace and AC maintenance. Their customer service is excellent—helpful, friendly, and persistent in scheduling my maintenance. I appreciate that they've never pushed to replace my old furnace but instead helped me decide when to repair or replace without being pushy about sales. Finding trustworthy repair folks is hard, and I highly recommend them. You won't be disappointed.
A-TEMP Heating, Cooling & Electrical goes above and beyond to take care of their customers. I've been a customer for years and am impressed with the technicians and office staff. The fact that this is a family business is also a plus. Thank you.
A-TEMP Heating, Cooling & Electrical did a wonderful job. They were on time, wore shoe coverings, and worked diligently. They replaced our air filter and an electrical part under warranty, explaining everything clearly. The work was clean and professional, and the team was congenial and pleasant.
Everyone we’ve dealt with has been polite, positive, and very courteous. A-TEMP Heating, Cooling & Electrical quickly replaced our furnace during the coldest part of a snowy winter. Other companies couldn’t get out for 1-2 weeks, but A-TEMP assessed it the same day and replaced it in 2 days. Can’t say enough great things about this company!
