Authorized Service holds factory authorization from Whirlpool Corporation, which is what puts the 'authorized' in the name: its technicians are certified for warranty and out-of-warranty work on Whirlpool, KitchenAid, Maytag, Jenn-Air, and Amana. It also handles Sub-Zero repairs and covers Frigidaire and Electrolux out of warranty. Repairs are done in your home, and technicians come out with the parts most jobs need already on the truck, so the visit usually wraps in one trip.
This is a family-owned business, running since 1974 and still in the founding family's hands rather than a national chain. It works out of Greer and covers the Upstate, from Greenville across to Spartanburg. Reviewers tend to name the technician who came out and repeat the same points: on time, knew the appliance, and left no mess behind.
