Furnace repair

Furnace shut down without warning during the last cold snap. Outside temps didn't get above 11 F for 20+ hours. Sean was able to show up at the door within 3 hours of placing the call to Intelligent Service. Problem diagnosed, parts ordered and furnace up and running fast. Hats off and kudos to Sean and Intelligent Service!
