Should I leave interior doors in Douglas open or closed during heating and cooling?

Considering that air-conditioning systems inside our homes are closed-loop systems, they are made to move a particular amount of air throughout the house. Shutting bedroom doors results in the increase of air pressure in those rooms. The air-conditioning unit forces air in, but is unable to have it back out. This can cause the machine to force conditioned air right out of the bedroom beneath the door and through crevices or drip across the windows, wall plates, and ceiling fixtures, attracting this way hot attic or outside air by way of similar crevices and air leaks in the rest of the house.

How does an air conditioner (AC) work in Douglas?

Air conditioners carry out two essential works: heat removal and moisture removal, even in places, where there are monsoon months with higher-than-normal moisture concentrations. The lower the dampness level, more comfortable you will feel at a given temperature. As your hot indoor air is drawn up over the filter, it moves over a very cold coil wherein the heat and moisture are removed. If you've observed a PVC pipe running off your roof that drips water, that's the moisture removed away from the home.
