I used Desert Comfort Mechanical for the first time. I found them through an internet search, and they came out quickly. They were here right on time when they said they would be, and they got the equipment up and running the same day. They were going to come back the next day after another part came in, but they called to tell me they had to order the part from another city. They had to push the visit back a day, but I understood. I really like that they kept in touch with me the whole way.
