Those of us with forced air heating and cooling never get it comfortable in all the rooms in the house. Some are too warm, as the sun streams in, and some, farthest from the air handler, get barely a breath out of the vents. And closing the door to an unused bedroom may only make things worse.
Now there may be a smart product to solve that: sensors and adaptable vent covers direct heating and cooling where it’s wanted.
If you get one of these systems, let us all know how it works.
