"He is extremely attentive to your needs . What he says will happen , does! He keeps all appointments and thoroughly explains what he plans to do. He is one of the most reliable, ethical , conscience businessman I have ever dealt with. I have recommended him to friends . He actually went out of his way to help Ill friends deal with their generator problems even though he had not installed it. He made arrangements for someone to fix the generator when he was not able. Highly recommended !"

"Kevin did a great job installing our generator interlock kit. He responded quickly to my request for an estimate, he was on time for his appointment and he got back to us with an estimate ASAP. The work in our home was done efficiently and Kevin left the work area neat. The job cost was the exact figure quoted on the estimate. I highly recommend Electric Solutions and would hire Kevin again for any electrical work we need done."

"I had a small electrical fire on a Saturday from out dated cloth wire. These guys showed up got it fixed to where my house was safe and came back on a Sunday to get it 100 percent done rewiring my out door lights for my front door. Amazing professional work. They came back a little later and re wiring my entire house for me new panel new wires handled the permit. I can’t say enough about their work and professionalism I have no issue leaving them a key to work while I’m not home. Again amazing quality work"

Generator Install questions, answered by experts

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator.
