Ask anyone in the Midlands who lost power after Hurricane Helene in 2024 what they learned, and you will hear a version of the same list. The house got hot faster than expected. The hot water ran out, or the water stopped entirely. The freezer became a countdown. And of course, somebody’s phone died with no way to charge it. An outage is a test of the home you live in and how well your household has prepared. This post collects the lessons homeowners take away from a long outage, and what each one means for how you prepare before the next storm.
Comfort goes first, and here it can become a safety issue
A house in Columbia without air conditioning in July climbs into the upper 80s indoors within hours and keeps going, and the humidity rises with it because nothing is pulling moisture out of the air. For a healthy adult that is miserable. For an infant, an older adult, or anyone with a heart or breathing condition, it is a medical risk, and every summer emergency rooms see people who waited out an outage in a hot house. Winter outages carry the opposite lesson. During an ice storm, a home with a heat pump or a gas furnace has no heat at all, because both need electricity to run, and the indoor temperature falls toward the outdoor temperature over a night. The lesson is that in this climate, heating and cooling are not a convenience to restore eventually. They are the first thing to plan for.
Water depends on power more than people expect
Homeowners on well water learn this one immediately: no power, no pump, no water for drinking, flushing, or washing. Homes on city water keep their supply but lose hot water once the electric water heater’s tank goes cold, and even gas water heaters with electronic ignition stop when the power does. The sump pump in the crawl space stops too, which is a problem when the storm that caused the outage is still dropping rain on the house. An outage that lasts a day teaches you which of these applies to your home. The sump pump lesson in particular tends to arrive as standing water under the house, and a battery backup or a generator circuit for the pump is the fix.
The freezer clock and the medicine cabinet
Food safety runs on a clock most people learn during an outage. A closed refrigerator holds safe temperatures for about four hours, and a full freezer for about two days. After that, the contents are a loss. Refrigerated medication such as insulin has its own, shorter window. Households with someone who depends on oxygen, a CPAP machine, or refrigerated medication usually come out of a long outage having decided that backup power is not optional.
Power coming back can do its own damage
One lesson arrives after the outage. Restoration is rarely clean. Power often returns in flickers, or at low voltage for a few minutes while the utility brings sections of the grid back, and those fluctuations are hard on the compressor, capacitors, and control boards in air conditioning and heating equipment. A system that ran fine before the storm and will not start after it is a common call in the days after a major outage. If your equipment behaves differently once the power is back, running but not cooling, starting and stopping, or making a new noise, have it looked at promptly. Our technicians handle cooling repair after storms across the Columbia area, and video of the failed part comes with the diagnosis.
Portable generators have limits
Many households buy a portable generator after their first bad outage, and the second outage teaches them what it cannot do. A portable unit runs a refrigerator, some lights, and a few chargers. It does not run central air conditioning or a heat pump, and it will not run anything wired into the house unless a manual transfer switch was installed, since plugging a generator into a wall outlet sends power back into the grid and can kill a utility worker. It also needs gasoline every several hours, which means a trip to a station that may not have power either, and it produces carbon monoxide that kills dozens of people every year when a unit is run in a garage or too close to a window. Portable generators have a place, and the lesson is that it is smaller than the box suggests.
What to do before the next one
The preparation that follows from these lessons is not complicated. Keep a written log of outages and how long they lasted, because that record is what tells you whether your home has an outage problem or an occasional inconvenience. Know where your water main shutoff is and keep flashlights, a battery bank for phones, and a few days of water where you can find them in the dark. Keep the heating and cooling system maintained, since a system already running on a weak capacitor is the one that fails when the power flickers back. And if the log shows a pattern, or if someone in the house depends on power for health, look at a whole-home standby generator. It starts on its own within seconds of an outage, runs on natural gas or propane so there is no fuel to haul, and carries the heating and cooling system along with everything else.
Plan it before storm season
2nd Wind Heating & Air Conditioning has served greater Columbia since 1985, and every major outage brings the same calls in the same order: no cooling, no hot water, a wet crawl space, and then questions about generators. If you would rather work through those questions before the next storm than after it, schedule a consultation online or through the 24/7 chat on our website. A technician will review what failed last time, what your home depends on, and what it would take to keep it running.
