Shawn and Perfus did an excellent job. Shawn knew how to work with my older Luxaire and he was eceptional training Perfus, not only on the how but on the why, teaching safety and trouble shooting…Perfus did the work…he listened, he followed directions and has good sense about his tools and what he was doing…i have no doubt that he could replace a thermocouple on his own, here on out. They are a good team. I trust their work and would call again. Thanks.
