Generac Generators

Generac Standby Generators Sales and Service

Slusher Plumbing Heating Cooling Electric is a proud Factory Authorized Generac Dealer. We carry Generac’s full product line including: automatic backup generators, automatic transfer switches, portable generators, pressure washers and gas powered water pumps for Plumas, Lassen and Tehama counties.

Founded in 1959, Generac was the first to engineer affordable home standby generators, along with the first engine developed specifically for the rigors of generator use, and is now the #1 manufacturer of home backup generators. Generac manufactures the widest range of power products in the marketplace including portable, residential, commercial and industrial generators. They are also the leading designer and manufacturer of manual and fully automatic transfer switches and accessories for backup power applications up to 50 kW.

The Guardian and Synergy series of backup generators are our most popular line.


The Generac GP5500 Portable Generator features a powerful 389cc engine and 7.2-gallon fuel tank for powerful performance and excellent run time. The Generac GP5500 Portable Generator equips you with up to 5500 rated/6875 surge watts to tackle projects in places where accessing electricity is inconvenient or unavailable.  The GP5500 gives you the power you need during power outages, on job sites and during outdoor events.


Generac’s 16 kW Guardian® Series home standby generator provides the automatic backup power you need to protect your home in Lake Almanor, Susanville and Quincy areas. Connected to your existing LP or natural gas fuel supply, it kicks in within seconds of sensing power loss—automatically—and runs for as long as necessary until utility power returns.


Most generator engines have to run at a constant speed to produce electricity, regardless of the electrical demand. Generac’s patented G-Flex technology changes that by allowing the engine on the Generac Synergy to run only as fast as necessary to meet the electric load demand. Thus, the Generac Synergy matches generator output to actual power needs. The end result is a much quieter, more fuel-efficient generator.
