"Keep Smiling sent me Roy Wint and I'm very glad they did. Roy installed a replacement ceiling fan as well as four recessed lights. The result of the project is a much better lit and livable living room. I want to extend special kudos to Roy. He was very professional, polite, and friendly. A joy to have working on my home. He went out of his way to avoid creating any holes in the ceiling other than those housing the lighting fixtures. And he also did a safety inspection of my home's fuse box. I can't say enough good about this young man. I'll definitely be calling him the next time I need electrical work done in my home."

"Very impressed -- the company was very professional, the technician (I think his name was Jeremy) was prompt, polite, and knowledgeable. We had originally planned just to have a light fixture in one of the bedrooms replaced, but that morning found a great deal on a Ring doorbell. We asked if he could install that, too, even though it was a last minute addition, and he agreed to install it with no problem. It's always nice to work with a company that is so on top of service! That is hard to find these days, so highly recommend this company."

"I found Mr Sullivan on HomeAdvisor gave him a call which he picked up right away which was a plus, but than he gave me an estimate over the phone without coming down to look at it made it seem like the minimum he would charge was $350 for instal of four outlets, troubleshoot and repair outlets in kitchen, and repair backyard light. The next day he arrived a little late installed four outlets as discussed, but turned out nothing was wrong with the outlets in the kitchen he said the " GFCI where doing what they were supposed to do", and the back yard light was fixed by replacing the old sensor that rain water damaged with a new one, but replaced it with a black sensor rather than a matching white, which I was fine with in the end, unfortunately in the end he didn't recalculate the fact that he really didn't had to do anything with the outlets in the kitchen yet he was still trying to charge me $25 more for the unmatching backyard sensor. I am not an electrician and he and his employee did get the job done, but was just dissapointed that I believe he did not charge a fair price for work he done seemed too expensive to me usually an instal of lights or switches are around $50 a pop and the sensor $25 itself just didn't add up to me other than that they got the mission accomplished."

Generator Install questions, answered by experts

When installed and used correctly, generators are safe to use. The most critical generator safety tips to keep in mind are:

  • Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.

  • Never attempt to connect your generator to your home’s electrical panel independently; hire a professional for this dangerous job.

  • Never overload your generator by connecting more appliances than for which it’s rated; you can damage your generator and appliances or even cause a fire.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.
