Generator Maintenance Contracts

In order to keep your generator running at peak performance, we offer maintenance contracts. Our maintenance contracts include, but are not limited to, a bi-yearly checkup of your generator. We provide any repairs, oil changes, cleaning, and other various generator maintenance requirements as directed by the manufacturer of your generator. Our maintenance contracts are priced at $525 plus tax for a one-year contract, or $950 plus tax for a two-year contract.

Portable Generator Purchase/Rental 

Let's just say you would not prefer to purchase a standby generator--perhaps you do not own your home, or need a generator quickly because of a sudden loss of power from a big storm. We have portable generators in stock that you can rent from us for the time that you need it, and you can simply return it to us when you're done with it. If you would prefer to purchase a portable generator rather than rent one from us, we have portable generators in stock that you can purchase from us directly. We can provide you with all of the necessary equipment to directly hook the portable generator up to your breaker panel, whether it is a rental or a purchase.

Gisondi Generator Group is a generator dealer that was created in 2012 in the wake of Hurricane Sandy by John and Anthony Gisondi. Our goal is to provide our customers with a reliable source of power that they can depend on when they need it most--and we achieve this goal by providing frequent and thorough maintenance, service, installation, and repairs. The effort that we put into each and every step of the process is what sets us apart from other generator dealers, and ensures that you’ll never be in a freezing or hot home with no WiFi, A/C, heat or lights.

Join the hundreds of others using the state of the art service we provide and contact us today for your next steps towards your home generator. We look forward to working for you and your needs.
