"I'm very satisfied with his work. I had used him for 16 years and I had him install two different generators. I never had any problems at all and he is very responsive; that is why I have recommended him before."

"Paul did a great job of explaining what the problem was and the options available for addressing the problem. His recommendation for a solution was actually the least costly option. Paul presented as extremely knowlegable, professional and courteous. I was surprised at how quickly the installation was completed. The whole experience from the first contact with the company through the installation exceeded expectations."

"Anton is a great and diligent worker. He ran a pipe from my main panel in the basement to my garage. Given the distance and the difficulty of the work he turned a 2 man job into a 1 man job. He was extremely considerate and flexible. I will use him on all of my electrical needs moving forward."

"VERY pleased! Was able to make an appointment ASAP. On time, courteous, knowledgeable, trustworthy, honest, and very friendly. Bo knows his stuff! How he adroitly repaired my Casablanca ceiling fan switch & tested it in short order was amazing. I'm now having him service my Generac generator on a routine basis. I'd call Bo for anything electrical any time!"

"Pete was very nice and he was very knowledgeable about his job. I would recommend Watts Electrical to my friends and family. Pete gave my son in law a great idea and explained how to do it, he said that it was a good idea to save money, they just bought the house and he was very very nice. He did not make it the day before but he called to reschedule and he showed up the next day and was very quick to find the problem and explained how to fix one. We would recommend him for all of your electrical needs."

Generator Install FAQs, answered by experts

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.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

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.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more.
