"From the office folks to the electrician who did the work -- friendly and professional. They quoted the lowest price of three estimates and did the work within a couple of weeks. I purchased my generator elsewhere online... and VMA walked me thru the process of hooking it up, running it, and shutting it down. Very helpful."

"Kevin did an exceptional job installing an EV charger in my garage. His work was meticulously neat, ensuring everything was perfectly straight and tidy throughout. He skillfully managed the setup, maintaining clean and professional aesthetics from the electrical panel to the charger itself. From our initial call to the completed install, the process was smooth and swift, with Kevin keeping communication open and clear. His dedication to detail and quality work was evident in every aspect, making the whole experience impressive. Highly recommend him for his straightforward, professional service. Also, a shout out to Angi’s. This is my 3rd successful project via this service."

"Tim P, Generator Advisor, visited our house and gave on the spot estimatesâ ¦..he was GREAT. Licensed Electrician who knew his business and was easy to speak with. Timely communications and responses to text messages! Tim was helpful answering questions after the generator was installed. We talked to 5 Generac dealers and a Kohler dealer. Cotti-Johnson had the best pricing in the South Shore area. We highly recommend this company. If you are thinking about buying a standby generator, Cotti Johnson is the company to callâ ¦..Art V"

Generator Install questions, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.
