My heater broke on Thanksgiving. A technician Shawn came right away. Assessed the problem and tried for a temporary fix. Two days later, Nick came to explain the repairs and all options of replacing the heater. Three days later my heater was replaced quickly and efficiently by Tom who took the time to explain the new thermostat and heater. With Giannone you get a whole team of experts to solve your problem and they are always available to back up their work. Great experience.
