I phoned in about 11 AM. Receptionist promised a call back and it happened around noon or so. Service tech called also to tell me he was leaving and arrived 15 minutes later. He diagnosed the problem,ordered the correct pars which was available in town. It was delivered to my place and installed. Heat exchanger was cleaned thoroughly and now is up and running. The process from initial phone call was about 6 hrs. I had called another firm 4 times in a week with no callbacks on their part. Thanks for the Great Service.
