"This was the first time I used Home Advisor to find a contractor. Home Advisor linked me with Mr. Electric who did an outstanding job. They were on time, on budget, courteous, professional, and totally a pleasure to work with. Thomas installed a 50 and 30 amp service for us at our property servicing two RV lots as well as installed a power pole with a meter box for the power company to tie into. Jan was a pleasure to work with as she was the voice for the company dealing from everything from scheduling to invoice as well as general questions. Jan was very pleaseant and professional. We will use Mr. Electric in the future and highly recommend their service..."

"I needed a port installed to plug in my portable generator, and properly shut off the utilities to house in case of power outages. I am SO GLAD this is done. We have a lot of storms in this area, and the peace of mind knowing, it is no big deal now - I have a back up system - is huge. And it was done so quickly!"

Generator Install questions, answered by experts

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.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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.
