Eric Suarez. Same out and quickly established what was wrong with our heater. It was under warranty and before coming down from the attic had already ordered a new motor and scheduled it to ship directly to my house. The next morning the part arrived and within a few hours Eric was back in the attic and had it up and running again in less than an hour. He could not have been more courteous, Or patient in explaining exactly what was needed. I would not have a second to have him back out if the need arises.

The guy was very good. His suggestions were spot on. Everything went smoothly. Courteous and polite...only negative is not of him, but the billing department. I kept getting emails, text that I need to pay the invoice when I paid the invoice onsite.
