I have an AquaPro1100 and it just died. I need a qualified repair person in the Fairfield County/Westchester area, just outside New York. I had an HVAC person working on it and it seems they don't know how to fix it. Something to do with the heat exchanger leaking. The technicican didn't have the specialized tools to deal with the titanium heat exchange part, apparently. (And this is a top HVAC repair outfit, by the way. Been in business for 50 years.) AquaPro is not really being very helpful -- the outfit they authorize to do their warranty work in my area has gone out of business! Any suggestions greatly appreciated.
