"Ryan did a great job installing a bathroom light/fan and venting it through the attic to the exterior of the house, replacing 3, bathroom outlets that didn’t meet code and installing floor outlets in my living room. He and his assistant were professional and efficient and therefore a pleasure to work with. I plan to have him do some additional work in the future."

They cleaned up after themselves, they did some extra work without trying to nickel and dime me. I am very happy with the work they performed and will gladly use them again."

"David did an amazing job. He called me very quickly after I signed up on Angi. He set up a time to do the job within 4 days. He got both jobs done in a very short amount of time. His price was really reasonable. I would not hesitate to hire David again!"

Customers say: Quick response

"Had a Tornado hit my house and ripped out my mains power. Figured I'd upgrade the panel while I was at it and have a generator outlet installed for when I lose power again. Nick was VERY professional - gave me a quote, showed up on time, answered all of my questions, and the price was exactly where I expected it to be. Job was very well done. When the power went back on, my fridge didn't have power. He helped me pull the fridge out to find a GFI outlet, and he helped me reset it. Was really just a huge help! The guy is clearly a hard worker who really knows what he's doing. What I love is that I didn't talk to a sales guy who then sent a couple of kids to do the job. I got a quote, and the guy I spoke to did the work. That's awesome. I can't recommend this guy highly enough! Will reach out for any and all electrical work in the future."

Generator Install questions, answered by experts

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.

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.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.
