"A1 Plus Electrical had the best price, and the electricians and plumber did excellent work! The only problem experienced was that it took 5 to 6 weeks for A1 Plus to get the permits approved after stating that they could get the permits approved and install the generator within 2 weeks. All other companies couldn't do the work for at least 2 months or longer! I had to contact A1 Plus general manager to get things moving after several permit submissions were rejected by the city. A1 Plus mitigated this time inconvenience by installing an electrical outlet in the garage at no cost, and once the permits were approved, everything was done within 7 days. Permits were approved on Friday, and installation started on the following Tuesday, and city permit inspections were done on the following Friday! All within one week! Would I hire A1 Plus to install my generator in the future? YES!"

"Storm Guardian is a small family owned company. Of the three companies from which we obtained estimates I was most impressed with this company. The initial brochure with which I was presented when I  received the estimate was the most complete and informative about the company and the product.
Everyone was helpful. Myra and Cindy in the office were always very cordial and helpful in scheduling and giving me information. Example:Theywere very helpful in getting through the complexities of arranging meter pulls with the electric companies.The men that came for the installation were always on time and easy to work with (we had "mixed up" wiring in an old house). I was very satisfied with the whole process. It was a job well done.

"I recently had a subpanel and generator interlock kit installed at my home, and I couldn’t be happier with the experience. From start to finish, they were professional in every way. The quote was accurate and fair with no surprises, and they got me on the schedule much quicker than I expected. They arrived promptly, communicated clearly throughout the process, and completed the work efficiently in a short amount of time. The installation looks great and everything works exactly as it should. I would absolutely recommend them to anyone needing electrical work done."

Generator Install questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
