"Wonderful service! We had a whole house generator installed. Charles and Joyce were a joy to work with from quote to finish. They completed the work on the days promised. Scheduling to completion was quick and easy. They did everything right and was clean and neat and we are very pleased. We would recommend this company to anyone and would call them first if needed for any future projects. Wonderful company! Great people!"

"I called Don and inquired about getting my RV Onan 4000 generator repaired. It would start then run a few minutes and shut down. Don ask a few questions and quickly guessed it to be a failing fuel pump. He said he had to the parts in stock and could come to my RV site and repair it the next morning.....THE NEXT MORNING ! ! Most of the places I called on my journey said they could repair it but it couldn't be dome for two weeks AND then if it needed parts I had to wait another two weeks. So Don, shows up and within 1.5 hours he had it running perfectly, including a full service on it to boot. Don is the MAN. You will not go wrong with Don's Generator Service."

"Ever since my generator installation...every time we lose power, I smugly smile to myself as my generator deftly throws up its middle finger to mother nature. Thanks to Mitch Mountney and his incredible staff, I know I never have to worry about losing power again. It is a blissful feeling! Thanks Mitch!!!"

"Great on time service. Clean, efficient, professional and a pleasure to have working for me, they displayed the desire to "go the extra mile" to make sure that I was informed all thru the project and happy. Completing the job in a perfect manner was the only way acceptable to them, which pleased me. I had a complete residential electrical overhaul, Electric Pannel, Meter Box, etc., along with a Generac stand by generator installed, which also utilized the Plumbing division of their company. I could not be more pleased with the customer service, the work completed, the technicians and the pricing. Seriously, I hire contractors for projects that I am not comfortable attacking, and as for Contractors...they always disappoint me in one regard or another. there is usually some sort of problem or mis-representation or price changes, and I am always nervous about them being in my home and doing a proper job. Not these guys, I would have no problem giving them a key and alarm code to come and complete a job at my house without me there. The communication from them was outstanding, I received several texts with time frames and photo's of the techs along with some information. I have never had this type of contact and it was helpful and frankly pretty cool. If you have any type of work you are considering hiring a contractor for, you will be doing yourself a great service to use Mr. Sparky Electric or any of the other divisions of their company if your job can be handled by them."

Generator Install questions, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

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.

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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.
