10/15/20 Furnace & thermostat tune-up/ repair. Nick Walker was great. Knowledgable, professional and most importantly PATIENT & courteous with my many questions. When thermostat required replacement, he took the time to refit the new, slightly different sized thermostat onto the mounting plate in its very visible hallway location. It looks like it was made for it. His professionalism and personal manner convinced us to schedule your companies services for follow-on duct cleaning services. He is a great ambassador for Bill Howe.
