A generator sits quietly for a year and then has to work on the one night it matters. That means the battery, the oil, the weekly test cycle and the transfer switch, all checked before the storm rather than during it. These are New Jersey homes we look after on a maintenance plan, and plenty of the generators on this list were installed by somebody else. Each one names the equipment on site and the town, so what you are reading is work we actually did rather than a list of what a plan covers.

937 completed generator service projects across 142 New Jersey towns, including 165 with a review written by the customer.

Standby Generator Service in Middletown, New Jersey

Standby Generator Service in Middletown, NJ | Generac 26 kW | Client Since 2025
