We are a family owned and operated business that has been serving the Baltimore, Washington Metropolitan area since 1925. We are committed to providing superior electrical services. The valuable advantages we can offer you are great service, high quality and experienced workers at a competitive price.

"Do not use this company. They will rip you off. The contract was for eight 300W LED 40 ft pole lights, but I caught them redhanded installing 240W. Who does that? Then, they broke my lock and broke into my sprinkler room which I saw on my video which they admitted. Then, Kolb sued me for not paying the bill which I disputed due to lost tools as result of the break-in. Who does that breaking into a customer's sprinkler room and not informing that they did. I had to catch them on my video. Not only that it took over one year to the work proposed work. TOTAL FRAUD. I will be going to court...."

Generator Install questions, answered by experts

In many cases, you’ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

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.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
