Each & every year every one of us host the extended family for the holidays. And each & every year whoever actually gets the back guest room always complains the loudest about how frosty they are in our property. It has really gotten so worrisome that there are family members who now make a thing out of drawing straws for that actual room. That hurts. This year, I even gave up my own bedroom to sleep in the frosty room over the holiday season. Space oil furnaces didn’t even help. Besides, I can’t find it easy to feel safe having those things on while I sleep. After the holidays, I called the Heating & Air Conditioning equipment folks to see if they could help me out. The Heating & Air Conditioning guy was entirely thorough. He even had a thermal gun to study the temperature in different parts of the property. The Heating & Air Conditioning pro ventured outside of the frosty room to measure the temperature to see how much of Heating & Air Conditioning treated air was going out into the night air. He did find a very small leak around the corner of a single window. It was not significant enough to cause the total heat disparity in the room however. So, the Heating & Air Conditioning tech suggested that I go online & find some room to room ventilators. They are these little fans that are inserted near the top of an adjoining wall. The fans are then able to pull or push air in or out of the room. If the room is overly cold, kind of like ours, the fans will pull in additional heated air with the fans. I did just what he said & was surprised at the results. The frosty guest room is not freezing anymore.
