Here is my setup: 2400 sqft two story home with high ceilings in living room with balcony overlook in the game room upstairs
One 6 ton unit outside. Dual zones that uses a dampner. Controlled by two google nest thermostats. Main intake is upstairs in game room, secondary intake is downstairs. Change both filters regularly.
Lately, the upstairs will not cool properly all of the time. It will kick on the unit outside, inside blower comes on, but no air coming to the upstairs vents. It does this and the outside unit short cycles after about 90 seconds.
Downstairs runs and cools just fine.
It seems as though its just the dampner gets stuck, but the strange thing is, if I run the upstairs intake with no filter, it doesn't do this. But I can't do that for fear of damaging the system. Could it be the filter is causing its just enough loss of enough air to full open the dampner? And if so, other than running it without the filter, what can I do? If I leave it off for about an hour, it seems to help as well.
