Both of us live in a more than one story home that has more than four kitchens. Four of the kitchens are upstairs on the minute story, but the master kitchen is on the lower floor in the southwest corner. For some reason, the heating and air conditioner vents in the master kitchen just don’t seem to put out as much heating and cooling as any of the other air vents scattered throughout the rest of the house. At first, I thought that maybe every one of us had a blockage in a single of the ventilation vents. I thought that maybe an animal had built a nest in there, or possibly there was a sizable dust ball or a piece of insulation blocking the air flow from the heating vents. But after I took the covers off of the ceiling vents and the air ducts, I couldn’t find anything in either a single of them. That made me wonder if it wasn’t absolutely a problem with the ventilation ducts; maybe it was a problem with our heating and air conditioner plan itself. But our spouse said that made no sense since the rest of the home was doing just great with the same exact Heating and Air Conditioning system. That tighten it down to a single thing. The master kitchen was built on the first floor of the house, which was built almost a hundred years ago. The minute floor addition was only added in the last twenty years. I started to suspect that the reason every one of us weren’t getting much heating or cooling in the master kitchen wasn’t because our furnace and a/c weren’t working properly – or that the vents were blocked. Perhaps the heating and air conditioner were working just great but the insulation in that part of the home was the problem!
