Thank you for your prompt and very courteous response to our telephone call for service on Friday, February 15th. We had no heat in one of our zones and when I called for service mentioned that we had to leave our home by 11:00a.m. You were so kind to have someone here before our departure time and also to have sent a very capable and courteous service technician. Robert did his work efficiently, courteously and had a wonderful sense of humor. I think we all appreciate having people like that around when we are in need. Again, thank all of you for taking such good care of your customers and keep up the good work.
