"Dylan was great! He responded right away, and explained my options clearly. He showed up on time for both the estimate, and for the work. The estimate was very reasonable, and I paid him more than he asked for, because I felt he deserved more. Very pleasant personality, and I enjoyed meeting him. If I ever need an electrician in the future, he would be the guy I’d call for."

"Within 10 minutes if requesting a quote on Angi's John got back to me. Within 36hours , he came to my house at 645am ,before I went to work ,to do a walk. I had a bid that evening . I accepted the bid and 2 days later he got back to me with a date. , exactly 1 week from when I placed the bid request, the day after Memorial Day. He is always 15 minutes early and he had it done with the electric back on in 4 hours. He increased our electric from 100 to 200 amps and installed a surge protector. I am extremely happy."

"I normally don’t leave reviews, but working with Chad and SolarWorksGJ was an amazing experience! He was very well informed and thorough from initial sit down to install. He gave me a great deal on my panels and they look amazing on my roof. Very happy with the experience overall."

Generator Install questions, answered by experts

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

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.

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.

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.
