They persevered and fixed the problem!

I was having a problem with alerts to my email re: error messages. Clay and Jimmy stayed until they were satisfied they had solved the problem. It took another visit to a supply store and when they returned they had fixed the problem. Fortunately it was covered under warranty. These guys are the best!

Very pleasant annual service

Nick arrived on time and changed humidifier pads on the furnace. He checked the filters and determined I did not need replacement at this time. He also helped me program the thermostat for vacations and away time. Great service and a great help to me for the programming.
