"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"

"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

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding—power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

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.
