These guys are more interested in selling new equipment than providing a service. Not helpful at all, the "service man" was more of a salesman than a technician. He had no tools and I had to provide mine. Ended up doing the job myself for a total cost of $60. Their advice was "it is an old unit just replace the whole thing for $5500. Did I tell you about our financing options?". Do not call these people. I certainly won't.
