Mr. Shawn Foley came to my residence today on time and performed a thorough inspection of my heating system. The most valuable part of this inspection was Shawn's patience in explaining, in understandable terms, the workings and settings of the thermostat, plus the heating system in general. His advice will save me quite a bit of energy and expense. Shawn could not have been nicer, and I request him for next year's inspection. Thank you. Nick F.
