Even though I have a 15 year warranty on my furnace, the cost of the maintenance program is about the same as one annual maintenance visit, so it is a good deal for me. I also added my air conditioner because the warranty had just expired and I wanted to have that covered too. Direct Energy called me to make the booking and sent me reminders. The technician confirmed before he showed up and arrived exactly on time. He was friendly, courteous, and efficient. The maintenance checklists were explained to me to my satisfaction.
