The air quality on the top floor of our house is just not fantastic lately, and i do not know what is going on up there, however I suppose that there might be something wrong with our ventilation system, then at first, I thought that it was a concern with our oil furnace, then but our oil oil furnace is relatively up-to-date and the rest of the house stays hot all the time the way that it is supposed to. It’s just the upstairs that seems to be having concerns this winter; When I called our local heating and cooling company to ask them what they thought the concern might be, they said that they would have to come out and take a look at it, however that it sounded like all of us were having trouble with our air duct and not with our oil oil furnace. I did not want to do it, however I went ahead and made an appointment with them because something has to be done. Our kids all sleep on the top floor of our house, and it is honestly chilly cold up there. If it was closer to Springtime, then I easily would have just let it go! However, usually the weather does not start heating up around here until the middle of May, every one of us have very long winters around here, and the rapidly increasing temperatures are still honestly cold outside, however that means that the upstairs of our house is freezing, especially at night whenever everyone is trying to sleep. I am hoping that it is a self-explanatory repair and they just need to do some air duct sealing or something like that.
