Great question and not easy to do. For me, we keep a list of the best services in our area in the northeast, and we give these out to customers when they call. I would call your local independent store and see who they use and recommend. Always try factory service 1st as they are backed by the manufacturer. GE, Bosch, and Whirlpool, to name a few. If you go to their website and enter your zip code, let you know if they offer factory service in your area.
So local dealers, if accommodating, can assist. Then go for a factory tech if available found on the brand’s website,
