"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."

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.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

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.

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.

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.
