We just had Collin perform the yearly AC service for our 2 units. Collin was very professional , and thorough, I felt collin was committed to quality work. He took his time. explained all work being done. We have had Design Air service our units for 6 years. Outside of a ceiling saver needed to be replaced (190), We have not had any other problems with our unit. I do think the yearly maintenance is well worth the money
