"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 by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

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.
