Additional contact name - Mike Kambeitz. Financing available. Additional email - [email protected]

"Worst company I've ever dealt with. They charged me 100 bucks for material. They put in a shut off valve and 2 ft of braided hose. When I told him a shut off valve is 9 dollars he responded with Chinese crap on the Internet is cheap. When I said it was from Menards I got the same response. So this company is using solid gold fittings and platinum tape it seems. Also took 6 hours to get a call back from a man it took me all of 2 minutes to get so fed up with I told him to **** himself and hung up. **** you mike can't wait for the attorney general to give you a call"

Generator Install questions, answered by experts

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

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.

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.
