"Klaus, owner of Resolute Electric, showed up initially to complete the estimate. Klaus was on time, professional and left us feeling we chose the right guy for the job. Klaus provided an estimate within 24 hours, we scheduled the date of the installation and Klaus arrived exactly when he said he would be there. He was very knowledgeable about what needed to be done, did not hesitate to get started and completed installing the flood light in exactly the area we wanted and removed power to the base board heating at the junction box. The flood light needed to be hard wired and Klaus was nothing less than stellar from the moment we met him to the time he left after completing everything we requested. Resolute's pricing is very fair and anyone that uses Resolute will 100% be satisfied with the price and work performed."

"I converted an attic into a 1 bedroom apartment with private bath, kitchen and laundry area years ago and contracted Brandon Oakley to do all of the electrical work. The job was completed timely, professionally and without any issues. Since then his company, Legendary Services, has expanded its services to now include installing back up generator systems and solar systems for sustaining your electrical needs during power outages. I have discussed these options with him and he is very knowledgeable and I am considering installing one or both of these systems in my home. I trust his judgement and his work based on great past experience."

Generator Install questions, answered by experts

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
