This is what we need to do

I love my grandparents, and I admit that their old farm house has a unique sense of charm to it, but I don’t enjoy the inconsistent indoor air quality.  It doesn’t matter what season it is, you can’t expect to have the same air temperature from room to room at any given time. When the inevitable winter freeze arrives in November, the gas furnace and wood stove run in tandem.  The areas downstairs near the stove and in the rooms with air vents close to the air handler for the furnace are nice and toasty. But walk anywhere upstairs and you feel like you’ve walked outside. My grandparents have grown accustomed to this problem and get by on a space heater setup in their upstairs bedroom and an additional one running in the adjacent bathroom.  But the walk from the bedroom door, through the hallway, and down the stairs to the warm first floor is particularly frigid. I did some research on ways to improve my grandparents’ HVAC system to make it more efficient and have better heat distribution in the winter and cool air in the summer. I read that you can install dampers in ventilation systems that control how much treated air is sent to each individual room.  For instance, if more of your heart is getting lost in the room closest to the furnace on the duct layout, dampers can be installed ahead of the vents in those nearby rooms. The dampers block additional heat from leaving the ducts in those location so it can continue traveling to the rest of the house. Now that their ventilation system is upgraded, my grandparents have a much warmer upstairs. There’s still a bit of a temperature discrepancy because of the poor insulation in their old house, but the improvement is huge.
