Many thanks to R.A. Hoy company, and to Sean in particular, for fixing my heating system today! Sean went over every single part of the indoor and outdoor units, made the necessary repairs, and then double-checked everything before he left. He also went over every detail of the repair with me so that I understood what had gone wrong and what he had done to fix it. I am extremely grateful for this kind of customer service and attention to detail. Thank you!!!
