Called Penguin Air to see if the heating unit would cause a beeping sound. Was referred to Joe and with a busy schedule, worked me in, came to the house on time and fixed the problem quickly. Joel also performed one of my annual maintenance service and he is exceptional with a great combination of customer service and knowledge. Nice to know there are still people that take pride in what they do. I would recommend Joel for some type of recognition. Hope he is scheduled for my calls every time.
