"First, they were recommended to us for the whole house generator by home depot. We were so happy with the generator that we had him do a bathroom fan at my house and a bathroom fan at my son's house. I did some checking and that was a reasonable price. With the work he did, it was more than reasonable. The job was a little more involved than he thought it would be and he didn't have any problem with any of it. Without anything to judge the pricing from, other than online and a couple of guys I had come over who weren't on the same page as me, I'd say excellent. The quality was top of the line. As soon as he got the generator, he got over here to put it in. As a matter of fact, I am thinking about calling him again for something."

Generator Install questions, answered by experts

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 to 4,500 watts
Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

1,000 sq ft: 6–9 kW
1,500 sq ft: 7–10 kW
2,000 sq ft: 10–14 kW
2,500 sq ft: 12–16 kW
3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity.
