Home standby installation
Most of the homes we power run a Generac. We size it, pull the permits, set the pad, run the gas and electrical, install the transfer switch, and start it up. One company from the first visit to the annual service.
We visit, check your panel and gas service, and size the generator to what you want powered.
One price for the generator, transfer switch, pad, gas and electrical. We file the permits.
Usually one to two days on site. We test a real power transfer before we leave.
We show you how it works and set up annual maintenance so it's ready for the next outage.

Learn more: Free generator auditThe part most buildings miss
A 150 kW unit backing up a senior living building rarely carries 45 kW during a monthly no load exercise. When monthly runs never reach 30% of nameplate, the standard calls for an annual load bank test. It's an obligation the owner already has, and one most buildings aren't meeting.
