It took nearly six years but I finally figured out the cause and the solution of an HVAC anomaly that has stumped me.
The house we live in has a section in it where the heating and cooling just isn’t as effective. We noticed this pretty quickly as my daughter ended up switching to a different bedroom. We moved in the fall and by the time the gas furnace came on that winter, my daughter was always 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 area 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 bedroom. I even called the HVAC company out to see if the gas furnace and the air conditioning were messed up. The HVAC technician inspected every inch of the HVAC equipment and said it was all in tip top shape. That was good to know considering that the residential HVAC 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 part of the house had the same quality heating and air as the rest of the house.
