I appreciated receiving a reminder call for my appointment the day before, as well as a call the day of my appointment giving me a half hour heads up before the technician would arrive.
Mark was professional and considerate. He wore shoe coverings in the house when looking at the thermostat. He also offered and moved a few boxes out of the way of the furnace which I had forgotten to do ahead of time. The process went smoothly and he answered all my questions satisfactorily. I also trusted the information he gave me about my furnace, even though I wasn't able to see the work he was doing, because he told me the furnace was in great shape and didn't need anything else. This was surprising because our furnace is 13 years old and wasn't serviced regularly by the home's previous owner.
Mark also let us know the humidity level in our house is very low (we were aware of this) and gave us information about the two home humidifying systems they offer. His explanation was brief, and he wasn't pushy when I did not want to proceed with buying one of them.
It was an overall helpful and efficient experience.
