We have a new townhome which is 3 stories and roughly 1900sqft. There are 2 units - one for the upstairs (bedrooms) and one for the bottom two floors. We're in Georgia so its been hot and humid lately.
We keep the AC set to 72. The downstairs is fine, no problems at all. The upstairs is a problem. The unit is constantly running, and not only can it not maintain the temperature (it was 74 at midnight last night, with outside air temps in the mid to high 70's), but it is VERY humid. You can feel a noticable difference when walking up the stairs from the middle floor.
Any ideas? Was this just a poorly designed system? Thanks.
