After receiving a conflicting diagnosis from 2 companies, I contacted Moon Air for a third opinion. I had been told by one company that my furnace was not safe and they shut the gas off so the furnace would not operate. Moon sent a technician out within 2 hours of my call requesting service. Hector took his time looking over my furnace and performing a safety check. He was extremely thorough and explained everything he was doing. I thought I was going to have to replace my entire furnace, but after Moon came out, I was told my furnace was working fine and that I wouldn't need it serviced again for a year. I am very glad I contacted them. Thank you Moon Air!
