As of 10 Nov 2026, 8 written Google reviews of Gentech Washington Inc in Redmond speak to whole-house backup generator quotes: 6 say yes, 2 say no.
Yes, Gentech Washington Inc provides quotes for whole-house backup generators1. The owner or sales staff visit homes to walk through the process and provide pricing2, and representatives have given options and pricing for standby generators on the spot3.
Mixed experiences. Not every quote visit went smoothly: one reviewer said the salesperson was new and knew how to sell but not much about generators4, and another felt only a general amount of information was shared without receiving an actual quote for a starter package5.

Several mention feeling confident in his honesty and fair pricing, and multiple people compared him favorably to other quotes before choosing this company.
