"Aaron the owner came out on a weekend too do a wiring inspection on a house my wife and I just moved into. I made several calls trying too find an electrician and in a timely manner. Several tried to upcharge (and didnâ t know I am a licensed contractor in the state I just moved from. ) He provided not only honest answers but a fair affordable price that I can safely feel confident calling again for any further electrical needs"

"Bronson from Bismarck Heating & Air Conditioning came to my home yesterday to make sure our Air Conditioner is ready for the summer. He did such a great job, was efficient, knowledgeable and pleasant. And, what impressed me the most was that I had several questions regarding our heating and air conditioning system both of which were replaced late last year by Bismarck Heating and Air. He took the time to explain every question I had and was very patient in doing so. I appreciated his expertise and teaching skills very much. He is a very impressive employee!"

Generator Install questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
