Keeping the Fridge & Freezer Going
When a storm takes the power, the food in your refrigerator and freezer is usually the first thing on your mind — and a small generator makes saving it surprisingly easy. The secret isn't running the generator around the clock; it's knowing the simple food-safety clock, keeping the doors shut, and cycling the generator on and off so the cold coasts in between. Here's the plain-English version, with a printable, 29-page guide up top if you'd like the full walk-through.
Common Questions
1 How long will my food stay safe when the power goes out?
Food-safety experts say a closed refrigerator keeps food safe for about 4 hours, a full freezer for about 48 hours, and a half-full freezer for about 24 hours — as long as you keep the doors shut. Every time you open a door, warm air rushes in and the clock speeds up, so the golden rule is simple: keep it closed.
2 Do I have to run the generator all night long?
No — and this is the part that surprises folks. A refrigerator and freezer hold their cold for hours once they're good and cold, so you can cycle the generator: run it a few hours to pull the temperature down, shut it off to save fuel, and fire it back up when things start to warm. Running it around the clock just burns fuel you may not be able to replace.
3 What does a fridge or freezer actually need from a generator?
Less than you might think. While it hums along, a refrigerator draws only a modest, steady amount of power — but the moment its compressor motor kicks on, it grabs a much bigger gulp for a second or two. That brief start-up surge is what you size for. A small inverter generator handles it nicely, and its clean, steady power is gentle on the compressor and the sensitive control board inside a modern fridge.
4 Should I run the fridge or the freezer first?
When the generator is on, a modest unit can usually run both at once. If you have to choose, the freezer often comes first — it usually holds the most food and the most value, and kept full and closed it coasts the longest. The refrigerator's food spoils faster at room temperature, so watch its 4-hour clock and top it back up whenever the generator runs.
5 How do I know if the food is still safe to eat?
Keep a cheap thermometer in the fridge and the freezer. Food-safety experts use the 40°F line: if refrigerated food sat above 40°F for more than about two hours, throw out the risky items like meat, dairy, and leftovers. Frozen food that still has ice crystals or is at 40°F or below can be refrozen. When in doubt, throw it out — never taste to check.
6 What if I have several freezers full of a garden harvest or a side of beef?
Then the stakes are real, and it's worth planning ahead. Several chest freezers running at once — each with its own start-up surge — can outgrow a small suitcase generator, so you may need to size up and decide which freezer comes first. Keep them full so they hold the cold longer, put a thermometer in the most valuable one, and give me a call and we'll build a plan that fits your place.
Want a Hand With Yours?
Picking a generator, setting it up, and learning to run it safely is one of my most-requested visits. I bring the patience and the know-how - you keep your seat. We'll match a unit to your home, set it up right, walk through starting it and staying safe from carbon monoxide, and get your internet, TV, and devices happily back on. $99 flat, and every visit is 30-day come-back-free.

Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
