Not sure if it's the right place to post, but here goes. Wife and I are renting a small house (says 1000sq ft of liveable space) consisting of a main room, kitchen, bathroom, and 2 bedrooms, plus a full sized basement.
The heat pump is in the basement, with only a singular 4x10" intake right next to the filter. On the main floor, there are no air intakes, only air discharge registers, and the thermostat is in the middle of the house where no registers exist.
We often find that the basement is 10 degrees cooler than the living floor, which doesn't seem like much, but there are pockets on the main floor where the temperature reaches 5-8 degrees higher/lower than our thermostat is set.
We intend to get a couple of ceiling fans to help with air circulation on the main floor, but what would be a good solution for air exchange between the basement and main floor? We were thinking of setting a box fan at the top of the stairs to force air down there.
TIA.
