Common Mistakes to Avoid When Choosing a Standby Generator

Imagine this: the power’s out, and everything’s silent. No fridge hum. No lights. No heat. You grab a flashlight and head to your generator. You’re depending on it to keep your family safe and comfortable. But when you hit the switch, it doesn’t start. Or it powers half the house before giving up.
That sinking feeling? It’s exactly what you’re trying to avoid. A standby generator is a lifeline, but only if you get it right. The wrong choice can leave you scrambling in the dark—literally. Let’s talk about the mistakes that can turn your safety net into a safety hazard.
Choosing the Wrong Size
Failing to determine the right standby generator sizing doesn’t just waste money; it leaves you in the cold—or the heat, depending on the season. A generator that’s too small can’t keep your essentials running. One that’s too big guzzles fuel and drains your wallet.
Think about what you really need in an outage. Is it the fridge and lights? Or does your good pump and heater matter, too? Write down those essentials, check their wattage, and add them up. You don't have to be an expert. A dealer can help you figure out the right size. Getting this right means no more guessing games when it counts.
Forgetting About Fuel
Here’s the thing: generators don’t run on hope. They need fuel. And not all fuels work the same way. Some people realize this too late—like when they can’t find diesel during a storm or their natural gas supply gets cut.
Think about what’s reliable in your area. Natural gas is great if the lines stay intact. Propane stores well but needs a tank. Diesel works like a champ but has to be rotated regularly. The key is choosing a fuel source you can actually depend on during a disaster. This one decision can save you a lot of stress later.
Skipping Professional Installation
DIY is tempting, especially when you’re trying to save money. But here’s the hard truth: messing up generator installation can be dangerous. We’re talking fire hazards, fried appliances, and power that fails when you need it most.
A professional knows how to wire your generator safely and correctly. They’ll make sure it meets codes and gets the permits it needs. Yes, it’s an investment. But it’s nothing compared to the cost of a botched installation—or the peace of mind that comes with knowing it’s done right.
Neglecting Maintenance
A generator is like your car. You wouldn’t skip oil changes and expect your engine to run forever, right? Generators need care to stay reliable. And yet, maintenance is one of the most overlooked steps.
Check the oil. Change the filters. Test the Generac generator every few months. It’s not glamorous work, but it’s necessary. Skipping maintenance means risking a dead generator when you need it most. That’s a gamble you don’t want to take.
Failing to Test It
Let me paint a picture: the storm’s here, the power’s out, and your family’s counting on you. You try to start the generator, but it stutters and dies. Why? Because it hasn’t been tested since installation.
Don’t let this happen. Run your generator now and then. Let it power your essentials for a while. Make sure it’s ready to work under pressure. Testing isn’t just a chore—it’s a lifesaver. When the power’s out, you’ll be glad you did.
Conclusion
Buying a generator is more than checking a box. It’s about protecting your home, your family, and your sanity when life throws a curveball. Avoid these mistakes, and you’ll have something you can trust when the power goes out. Because in those moments, it’s not just about electricity. It’s about feeling safe, prepared, and in control.
