Good service. I love the maintenance plan; just wish there were specials for returning customers. Like $15 or $20 off. The only thing I did not like is that he didn't call me until he was done cleaning the unit as appt was 1 - 3 pm & he said he arrived at house at 12:40 & he called me at 1:30. I would have liked to been there while he was cleaning the unit. Other than that very professional & polite.
