Thanks so much for calling us out to help you with powering your new hot tub, Brianna! So glad you were happy with the communication, pricing, and clean workspace — we always aim to make every electrical project smooth and stress-free. Enjoy your hot tub, and reach out anytime for future electrical work!Posted onTrustindex verifies that the original source of the review is Google. I’m thrilled to have found “Three or Free” company. From our first appointment, Alexis exudes honesty, trustworthiness, and professionalism. He actively listens, answers all my questions, and provides clear explanations. During our second appointment, he went above and beyond by presenting me with a comprehensive file containing various quotes to choose from, along with his license number and information about his excellent warranty. This information was readily available for my convenience, eliminating the need for me to ask for it. In addition to his exceptional service, Alexis and his coworker demonstrated incredible kindness by volunteering to help move some heavy fridges that weren’t their responsibility. Their willingness to assist without being asked truly sets them apart. The overall experience was clean, efficient, and the people were fantastic. Kudos to this company for providing such a positive and reliable service!

Alexis and his team did a fantastic job with my project! I needed some electrical wiring done with a new duplex outlet in my crawl space for a radon mitigation unit. He also installed a cutoff switch outside by the system. They came out within two hours of my call and were able to complete the job the same day. They were courteous, professional, and communicated at a high level, so I was fully aware of everything that they were going to be doing onsite. The work was high-quality and the price was great, too! I highly recommend Three or Free Electric.

Thanks for having us out to add those 2 new outlets for you, Seyward. So glad we were able to help!Posted onTrustindex verifies that the original source of the review is Google. Alexis (and his assistant, Luis!) did an amazing job updating the electrical system in the old house my husband and I bought. From the start, he was the most communicative contractor we have dealt with. He was up front about costs/timeframes and stuck to those to the best of his ability. He always showed up a few minutes early. We trusted him enough to give him a key to our house to come and go the week he was working with us. He never tried to upsell us unnecessarily, but he was proactive in identifying hazards and small upgrades that we hadn’t even noticed or thought of. We completely trust the work he has done, as he is very thorough and honest… and one of the nicest people you will ever meet. Highly recommend hiring Alexis!
Owner's reply

I know how important it is to feel comfortable and trust the work being done, so I’m really happy you had that experience with Luis and me. Thanks again for having us help you with your new home’s electrical, Amy! If you ever need anything else, you know where to find us!Posted onTrustindex verifies that the original source of the review is Google. Alexis came out within 24 hours of our call. He came in my home with hectic kids and mess and was so friendly and engaging. Found the problem right away and fixed it. Done within an hour and very reasonably priced. We will always call him when we need expert electrical help.

Frequently Asked Questions
How long does home generator installation take?
Most residential generator installations take one to two days, depending on the complexity of your electrical system, the generator size, and any coordination needed with your gas or propane provider.
What size generator do I need for my home?
Generator size depends on your home’s electrical load and which lights, appliances, and systems you want to keep running during an outage. We’ll review your priorities and recommend the right capacity for essential-circuit or whole-home coverage.
Do I need a permit for generator installation?
Yes, standby generator installations typically require electrical permits and inspections. Our team handles the permitting process and ensures your installation meets all local building and electrical code requirements.
Can a generator be installed on any home?
Most homes can accommodate a standby generator, but we’ll evaluate your electrical panel, available outdoor space, fuel source, and local clearances to determine the safest and most practical installation options.
How often should generators be maintained after installation?
Standby generators should be professionally serviced at least once a year, and it’s a good idea to perform brief test runs monthly to confirm the system starts, transfers power correctly, and runs without issues.
Will my generator start automatically during outages?
Yes, properly installed standby generators are paired with automatic transfer switches that sense utility power loss and start the generator within seconds, then switch back to normal power once the utility is restored.
Where should a home generator be installed?
Home generators must be installed outdoors on a stable surface with proper clearances from windows, doors, vents, and air intakes to prevent exhaust from entering the home. During our on-site visit, we’ll identify a safe, code-compliant location on your property.
