Best Air Balancing in Cleveland OH

Installed a furnace for us in closing of house. Leaked water when AC on from day one where new furnace connects to duct. Furnace somehow was also disconnected from generator on install. I called and told them first summer and was told nothing they can do because it was not their duct. Clearly, it is because of new piping drainage and hook up but they would never be accountable. It now leaks massively. Actual owner Smylie seems very nice came out and rigged electric to furnace when power was out yet claimed it must of always not been connected to generator. He however seems to have very incompetent employees. Furthermore, we tried to use this company for plumbing and each time a guy comes out and then nothing. We have been told that guy quit so a new guy is needed. Stay far away from this company.
