"10 yr old Generac GP6500E wouldn’t start. Called around and many want to upsell to permanent. Found Franks and what a delight. Honest, down to earth, affordable for senior. Showed up on time. Changed oil, spark plug. Pulled carburetor and found it dirty and fouled. Got used one from his shop(same day) and installed. Gen started right up on one or two pulls. Battery was dead but showed us how to replace. Highly recommend Frank’s Generator."

"When I placed a request for the installation of two outlets on Angie's list, Steve got in touch right away but wasn't overly pushy either [which happens sometimes]. Between the three weeks I first spoke with him and the job, he was professional, informative, and responded to texts quickly and I knew exactly what to expect on-site as well as the cost. He sent pictures and cost of a similar job to help explain the work and the estimate. Steve identified some other issues with my electrical panel and made some small fixes--without increasing the cost of the job--and made some recommendations for me to consider in the future. He was courteous, professional, and seemed to care about the work and about communicating what he was doing and why. I would definitely turn to him first for my next job."

Customers say: Terrific value

"It went very well considering they had to move a lot of stuff in order to get to the spot where the new panel was going to be installed. They were courteous and friendly and put everything back to where it was when the no was finished."

Generator Install FAQs, answered by experts

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

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.
