80 degrees in my home

My home must be put in genuinely weird. I am thinking that the trees surrounded my home make for warm in addition to frigid spots, but then the Heating in addition to A/C unit is not large enough to deal with my home, or set up in the wrong spot. No matter the reason for this, I want the tepid in addition to frigid locations. In the Winter time weather, I run my furnace plan non stop. My whole room in addition to dining area are toasty warm. The space that I work in is icy cold. I thought perhaps the window in the office was not connected that tight. I bought all brand new windows and also even redrywalled that room. Yeah, that room still feels as if the furnace never will get to it. The heating device is not that far from the office at all, but what is the deal with this? In the hot season the office in addition to most of the house gets a/c access. My home office however, typically seems to be warm. It is tepid in the Winter season in addition to gets no AC in the Summer. That makes no real sense to me. I could set up ductless A/C in the home office if I wanted to. But, I own a better cooling system. The A/C should be able to deal with the whole house. I refuse to buy another Heating in addition to A/C units like portable A/C in addition to section heaters.
