"I had American Electric complete the wiring for my 24x40 garage along with a 200-amp panel upgrade to my house, and I couldn’t be happier with the results. From start to finish, the communication was excellent, they were punctual, reliable, and the quality of work was outstanding. Everything was done professionally and exactly as discussed. I would absolutely refer them again and highly recommend them to anyone needing electrical work done."

"Pete was very prompt and professional. He was able to upgrade all of our outdated outlets in one full day. Unlike past electricians who have come across a bit grumpy, Pete was super friendly and seemed happy to walk us through all our silly questions. I would highly recommend Pete if you want the job done thoroughly and with a smile!"

Generator Install questions, answered by experts

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.
