"I hired Mike for a back-up generator installation. Very quick response, very good communication: he explained everything thoroughly, and invited questions. Mike is very professional, while still being personable and pleasant to deal with. I would call him again for future work."

"My solar inverter stopped working in my existing solar system, and since my original installer went out of business, I had a hard time finding someone to replace the inverter provided by SolarEdge. It was a small job, and most large companies weren’t interested, while those willing to help were booked out for at least a couple of months. I contacted Justin, and he replaced the inverter within just a few days. He was very friendly, efficient, and offered a very reasonable price. Justin was also extremely knowledgeable, explained everything clearly, and kept me updated throughout the process. He arrived on time, completed the work neatly, and made sure the system was running perfectly before leaving. Overall, his professionalism, honesty, and dedication to customer satisfaction made the whole experience stress-free and smooth."

"We had a great experience with Andrus. Tony came out before our Kohler generator installation to clean up our electrical panel and did an incredibly thorough job. Everything was left clean and organized. The generator installation itself went very smoothly. The team was professional, knowledgeable and respectful of our property, and everything was explained clearly along the way. We're very happy with the finished installation and feel much better knowing we're prepared for the next outage. Would definitely recommend Andrus!"

"It was okay. I think I spent an additional $600. I liked their crew, the owner himself Anthony Berry and he had a person with him. I thought the work that they did was very well done. They cleaned up after themselves. What I didn't like was the fact that they didn't have the supplies that I needed in order to get the job done and then one of them had to leave 3 hours and go get supplies. I was paying for that whole time so it was a little disappointing to me that what I thought could have gotten done fairly reasonably quickly ended up taking a lot longer. My interaction with them and their work were good. I think they should have called me ahead of time and I would have told them what work I wanted done so they could have been more prepared. I felt that they were a little bit unprepared for what I needed done so they just need to be more prepared in terms of having their supplies and stuff. I will not use them again simply because he's actually located very far away like I'm at the very edge of his service area. He's located an hour away and there are other providers with closer proximity to me."

Generator Install questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.
