It took several years but I finally figured out the cause and the solution of a heating and air conditioning anomaly that has stumped me.
The home we live in has a section in it where the heating and cooling just isn’t as effective.
We noticed this pretty hastily as our child ended up switching to a different room. We moved in the fall and by the time the gas furnace came on that winter, my child was regularly cold. And once I sort of took notice of that end of the house, I could see just what she was experiencing. So that room sort of became a storage section and last resort guest room. Actually, there was so little heating and cooling in that room that if we had additional guests, one of us had to give up their family room. I even called the heating and air conditioning company out to see if the gas furnace and the air conditioning were messed up. The heating and air conditioning professional checked every inch of the heating and air conditioning component and said it was all in tip top shape. That was superb to know considering that the residential heating and air conditioning was replaced just prior to us buying the house. So just this past spring, I finally figured out that there were interior walls added by the previous owner. And this is what caused a disruption in the heating and cooling transmission. So I installed some room to room ventilation fans inside those walls. Immediately, that section of the home had the same quality heating and air as the rest of the house.
