"DES installed 2 new electrical outlets, 2 new electrical panels, 3 wall heaters with dedicated circuits, and other miscellaneous electrical work. They explained options and what they would need to do to get the job done correctly. They arrived at the scheduled times, worked around our dog, explained the work they were doing, were friendly and easy to work with, and explained color and size options. When a light malfunctioned, they quickly scheduled an appointment for the waranty work which I am very satisfied with. I would hire them again."

"Three electricians worked on the job & completed it in 3 1/2 hours! I was expecting it to be done in 5-6 hours. They even hooked their generator up to my big freezer! The City inspector just checked their work, said it was a job well done! I would definitely hire them again."

Generator Install FAQs, answered by experts

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
