I encountered a very strange scenario with my thermostat and furnace, Once the thermostat reached the desired temperature, the furnace and blower stayed running, to make things even odder, when the thermostat kicked in, the AC compressor also started.
A friend recommended I call Modern Heating, I had an appointment within two days. The technician was very courteous, and professional. He quickly diagnosed and resolved the issue.
It was a great experience working with this company.
