I'm new to the forum. I would appreciate any input and I apologize if I'm asking something that has already been answered before. I had an issue with my climate master tranquility unit and AC. The service man found that one of the circulating pumps was unhooked and the company has no record of anyone disconnecting it. He added water to the loop and He reconnected the pump it and it is hot to the touch now. Only the one pump is hot. Is that a sign of something wrong? Also it had been 2 years since the company had been out to do anything to the unit and I'm guessing that the one pump has been disconnected for that 2 year period. Would that pump not running affect the efficiency of my furnace?
