The person who first came was there to do a routine annual furnace cleaning. Because he discovered that there was a problem with the furnace, there ended up being a second person who came to replace the part that was not functioning. Once he had replaced that part, he realized that there was a second piece that was not working properly, so he arranged for that part to be ordered, and returned the next day to replace the part. Both people who came to the house provided excellent service. They were polite, friendly, knowledgeable, helpful (there were a couple of different options to consider, and they explained things very clearly). I have received a lot of service calls over the 30 years that I have owned my house, from a large number of different companies. I have never been so impressed as I was with the people who came from Direct Energy.
