There are drafts in the house

Last week, I kept complaining about the draft that was in my laptop room.  He had the Heating plus A/C company out during the warm season plus they told us that there was no energy loss in the room.  I begged to differ with them. I told him the people I was with and I needed to get the Heating plus A/C company out here when the people I was with and I were having high winds in the Wintertime.  He rolled his eyes plus mumbled as he walked away from me, but he called the Heating plus A/C company. My spouse doesn’t spend any time in my laptop room. He has no plan what I am talking about. When the Heating plus A/C company arrived, they went right to the laptop room.  They immediately found a cold spot plus it was coming from behind the built-in cottageets. They investigated this, thinking that there was no reason for there to be an air leak coming from there. The cottages were installed when the condo was built, which was long before the people I was with and I lived here.  I told my spouse that if the people I was with and I had to, I was going to rip out the cottages to find where the cold was coming from. The people I was with and I were paying for heat plus the people I was with and I shouldn’t be losing it. When the Heating plus A/C tech went to the basement plus looked at the floor underneath my room, they found the problem hastily.  There was an air vent that led into my laptop room, however there was no Heating plus A/C pipes to lead to the air vent. Since the people I was with and I didn’t have AC, there was no air coming up in the warm season, however during the Wintertime, the open air vent was a direct line for all of the cold air that came into the house, when the door opened.
