Our furnace was not working during the Mid April 2018 ice storm. Bobby drove out to our house on Sunday night in the worst conditions imaginable. After conducting rigorous diagnostics on our old furnace, they concluded the heat exchanger was cracked and the whole furnace should be replaced. They came back the next day and replaced the furnace within 18 hours of their initial visit so our house was nice and warm when our daughter came back from day care. Amazing service. Always try to fix or repairs rather than replace in order to minimize costs.
