Jarvis electric is a local family owned and operated business. We take pride in performing quality electric work at a reasonable price. We have over twenty years of experience in the electrical field. Honesty and integrity are two qualities we believe help to build a successful business. At Jarvis Electric we are building relationships, one job at a time. Update: We are currently not servicing East St. Louis.

"Jarvis Electric did all of the electric for our new build and has come back to add additional items that we have added since we have been in the home. Super responsive and quick to complete all requested work. Top notch service. Extremely reasonable price. I appreciate that they always keep a clean worksite and never leave a mess, even if coming back the next day to finish a job. I have not only used them for my home but referred them to my mom and dad as well when they needed work done. Great company with great people and really easy to deal with. They truly went above and beyond."

We are the experts in the field of Whole Home Generator Sales and Installation, with over 20 years of experience in the game. We provide turn-key installation by licensed professionals - 24 hour emergency service - Remote Monitoring - Long term maintenance and service by factory trained technicians.

"They initially contacted me via email ready to make a visit for the install. Said that they could do the project no problem. Then when they realized I wouldn’t be buying a generator from them, which I had TOLD them upfront, they canceled on me. That is not an acceptable way to do business. They should simply state that they only install generators that they sell and not waste my time."

Generator Install questions, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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. 

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.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
