I have a very new and heating & a/c plan in my home, and i spent a lot of money on it as well! For the last three or four months it has worked pretty well, until recently, however recently I had discovered a major problem with the air flow of the heating & a/c unit, but my hallway for some reason was getting a bunch of heat moved into it! I have unquestionably had the a/c on a bit lately as it has been a little warm outside, why my hallway was getting heating instead of cooling was beyond me. I realized right away there may have been something wrong here. This is the exactly moment when I called the heating & cooling supplier that installed the Heating, Ventilation, & A/C system. I told them what was going on. Then, they looked at my history & told myself and others that I had heating & cooling zone control. I did not even understand what in the hell they were talking about! They went on to explain, that the plan I got can make uncommon areas of the apartment uncommon temperatures, however after this, I then noticed that I had an additional control component on the wall of the hallway! That control component was not even running. This was why it appeared that I was getting heating in the hallway. I thanked and hugged the heating & a/c supplier for unquestionably explaining all of this to me. I felt pretty close to a real idiot to be at that point. With that being said, at that point, I flipped on the control component in the hallway, & now it was cooling off. I will not make that error in judgement ever again!
