Been using these folks for a decade for repairs & tune-ups, except when I had an HO warranty as they don’t do HO warranty work. They only sell, maintain, & repair Trane A/C Heating units. They have a plumbing dept. as well. Prices are reasonable… maintainance agreements are available which gets you 15% off repairs and priority service. Staff &Technicians are professional, courteous, and dependable. Trane is number one according to Consumer Reports… take it from me .my Trane unit continues to amaze people as it is 20 years old and I have only had 3 minor repairs.
