"Roy is really a prof. He installed two overhead fans and a hanging lamp. The fans had a complicated control system but he was able to get them to work flawlessly. Bonus: he is really a nice person and he cleaned up too! I would recommend his work to anyone."

"Hank's Electrical is a quality company. I have used him at least 4-5 times within the past 1-2 years and he never disappoints. He has done a number of jobs at my house including outlet installation, landscape lighting and generator installation. Extremely responsive and aims to please. He takes pride in his work and is very efficient, tidy and will give you a fair and honest estimate. Would feel very comfortable referring him to family and friends who need any electrical work."

"I have used Pipe Works on numerous occasions as of this date and find them to provide excellent service at competitive prices. Their associates are great to work with and their prices are competitive. The work is always completed on time, as promised and the work area is left clean. I appreciate that they point out things that need repair in the not so distant future. It was great to wake up the other day with power coming from my new Kohler Generator"

"We recently hired Spartan Home Pros for a multi-zone mini split installation, and they did an outstanding job from start to finish. A special shoutout to the lead technician, Charles—he was incredibly diligent, meticulous, and dedicated throughout the entire installation. ​Charles took the time to ensure every line was run cleanly, all wiring and line-hide covers were neat, and all manufacturer clearances and specs were strictly followed. They handled a tight installation spot upstairs with total professionalism and made sure everything was done right the first time. The team left the job site completely spotless, and having the system up and running with both heating and cooling working flawlessly is an amazing upgrade for our home. If you want true craftsmanship and honest, reliable work, I highly recommend Spartan Home Pros!"

Generator Install questions, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

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.
