I purchased my heating and cooling system as well as the hot water equipment from Pann Home Services. Following the purchase, they have been taking care of regular servicing for me for the last couple of years. Whenever I call, they are very responsive. I've never had too long of a wait; they're usually there within a couple of days. The technicians who come are knowledgeable and easy to deal with. They are professional and competent in what they do. Their pricing is reasonable. Whenever I've had any issues and have needed to call them back, they have come right back out and dealt with it. I'm quite happy with the service they provide.
