Your technician Joe came out yesterday to check over one of our units that is acting up. He is the nicest, most professional guy ever. Took the time to listen to what we were experiencing and then thoroughly go over the whole system. Explained everything that he found; what the options are and why; called to see what the lead time is and when he could get us on he schedule etc. Definitely has that quality which makes the client feel comfortable when he's coming into your home to go over a major system.
