I have worked with AAA Plumbing LLC since 2009 as then-Chair of the Board of Trustees of First Ecclesiastical Society of East Haddam, Connecticut/First Church of Christ Congregational in East Haddam. At the time, we had AAA design and install a replacement system for an outdated steam system for the 1794 Meetinghouse. A design criteria is that it needed to be able to be shutdown completely, just like the steam system, as there is no water in the Meetinghouse part of the building. Two Unico System air handlers were added and connected to the newer boiler in the then 7-year old addition that had plenty of capacity to handle it. The solution was perfect and very quiet, although some missed the occasional clanging of the old steam pipes. I have since had service work performed on the Unico System air handler in my 1834 residence. Very pleased with all experiences and are my "go to" HVAC contractor.
