Jeff stayed on the problem until he was sure he had diagnosed the issues correctly then corrected them. As it turned out, previous Grand Oaks installation and tech person installed the thermostat incorrectly. And never followed up as promised.
Jeff from Grand Oaks showed up at the approximate I was given. He was very polite upon arrival and walked me step by step through my repair process. Couldn't have asked for a better service tech!!!
