Chapman Builders LLC is a responsive, professional, and honest company that specializes in electrical work. Fully licensed and insured in NH. Some of the main installs I do include 200 amp home service upgrades, led lighting installs, and removing old wiring such as knob and tube. Chapman Builders LLC also does other things such as home rot repairs, remodels, flooring, and much more.

"Charles was heartily recommended by my neighbor who, like me, has lots of home remodeling experience. The main task was to replace a whole house generator and, as it turned out, upgrade/rationalize multiple older panels servicing a big home, apt and shop. Charles presented several options with rough estimates, I picked one and he gave a firm estimate with itemized parts list and labor. We picked a date and Charles executed the plan…as planned. A little color. Charles is a big, fit, articulate young man with a strong sense of how a professional ought to comport himself. He started work on the main panel in my garage. Late November in NH. His shoes were sitting by the door and he was working in his socks. I didn’t expect it but what a pleasure to find such a pro. What about $ you ask. I estimate that I saved $10k compared to you know who. "

Generator Install questions, answered by experts

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.
