Couldn't get to the "19 more choices" of services to check off install of smart/wi-fii thermostat. ALLEN did a fabulous job replacing the thermostat with smart/ wi-fii capable one. Took care of a minor issue from the furnace install in January and signed us up for a maintenance plan on HVAC. He was knowledgeable, and patient working with us on workings of this new thermostat.
