"It was pretty rocky. At first. Several appoints made by Tri-State no one ever showed up.Crew showed up to install the Generator before the site survey and did not have necessary equipment or cooperation of Electric or gas company nor call before you dig had been notified. I called Tri-State to warn them the call before dig had never been preformed. They said they'd take care of it, did not happen until right before installation crew came back the second time. The first time they were here they could not have installed the generator even had they had all the parts because none of the utilities had been marked. Finally after about three months the Generac was installed and working. I had several questions that I could never get answered by calling Tri-State. One of the installation team had to come back a couple of weeks later to replace a damaged part and he answered all my questions. The guys who installed the Generac were great, the problem is your guys operation center and call center as far as I can see do not communicate very well. Anyway the generator has worked fine in several power outages this spring. I am happy right now but I live in dread something goes wrong and I have to call Tri-State for help."

"Was pleased with work that was done. Brandon and Thomas arrived around 8:30am and was finished around 4pm. Old air conditioner ran consistently.....excited that I now have cool house without air conditioner running all the time. Brandon also checked to make sure furnace was working. Both were congenial and kept me informed of work progress. Appreciated them coming on very warm day....not comfortable in upstairs attic! Also, appreciate helpful customer service reps and Heath the Company Rep who came out earlier and explained price, warranties and install info."

"Slow response and the labor costs was quite expensive. More than I would have expected to pay for a warranty job. The parts were covered by warranty, but Maeser charged a high premium for the labor. I would have expected them to give me some sort of break seeming they recommended the original unit and did the install. There are less expensive service providers out there and I'll turn to them when I need additional work done."

"Called and setup an appointment, they explained their pricing which was very reasonable. They called when they said they would, and arrived when they said they would. Very friendly, likable and professional. Explained everything as they went, what they found, what they did to fix the problem, etc. They also provided a written quote for additional remodel work that we may have them do in the future. Overall a very good experience. Would recommend them."

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

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.

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

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
