Hello,
I am new to this group. I have a problem with the heat in my house and cannot turn it off. I have 5 zones. One zone will not cool down. I don't have a leak. I have had a plumber, leak detection service, and now heating group (HVAC)working on this. New flow valves, new circulation pump. With thermostat at 50, room is 80. We are tearing our hair out. Seems like if one zone is calling for heat, this zone heats up. Believe they checked the wiring. We cannot get under house to see whether it is piped incorrectly.
Any thoughts appreciated.
