If it's a zoned system then yes, damper problem. Are the dampers...

near the indoor unit where you can observe them operate? Sometimes they just need a little jolt on the side to close. It could also be in the electronics, which means you're calling the original installer. If you can figure out who that was.

One unit for heat? one thermostat? ** -- bigbadbird 01/07/2022 08:09AM

One thermostat for each floor. -- ElbertoHokie 01/07/2022 08:13AM
