"The process from beginning to end was highly professional, technically very competent and complete, and the installation was impressive (Team of about nine people, all worked efficiently and simultaneously outside and inside my house. The job was done in a little over half a day. Very happy with my decision to hire GAC to spec, supply, and install the system."

"Mr. James Rollins was exceptional. Had an issue that came up last year with my Generac generator and he was quick to respond but I was not able to be as fast. Power came back on so I didn't follow up. Generator hasn't worked and was worried about a power outage, so I reached back out. He came out on the same day, diagnosed my issue in a minute, and fixed it. His work was outstanding and I can understand why he is so busy. Everyone wants Rollins Repair. If you can get him, I would ask James Rollins to help you."

"Simply amazing from start to finish! I can't say enough nice things about this company or the people that I dealt with. They were all professional, friendly and they did great work. They called me just minutes after I clicked their name on Angi's List and had someone out to give me an estimate and had my appointment date set in record time from most companies that I have dealt with for home improvement. I hate having people in my house working but I felt totally comfortable with them. The work they did was exceptional. We got a new power box (breaker box - whatever it's call) and a new meter and a couple of new outlets put in. We also got new smoke detectors throughout the house. They had to work around some issues and relocate a bit of pipe from out water filter system that was in their way. And they just took care of it without any complaints. I didn't have to do anything. They took care of it all and had the inspector come out and get it approved. I feel safe in my home now. I highly recommend this company and I will be calling them for any future electrical work that I need done."

"Anthony and his team do expert electrical work of all kinds. We are a 145 year old non-profit organization with buildings and grounds, and have contracted with Technician Engineers Group (TEG) on two large projects (and several small ones) over the last 15 years. One project rewired a large 125 year old building listed on the National Register of Historic Places, and one installed an extensive outdoor lighting system. In these two unusual situations TEG worked closely with us to find innovative solutions to our unique needs. We are very pleased with the results, enjoyed their can-do approach, and highly recommend this company for any electrical challenge. We found TEG reliable, honest, on time, and all the work was completed ahead of schedule."

Generator Install questions, answered by experts

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

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.
