Pardon the super-off-topic post, but I'm having this issue at my house, and I thought the collective experience on the board could help figure it out.
About 18 mos ago, we bought a new-construction house in Orlando. I think one of the bedrooms may have one or more windows that are not keeping a seal and is releasing cold/ warm air or letting in warm/ cold air (or a compbination of both).
This upstairs bedroom has four windows. This room - and only this room - always seems to run warm, no matter how the a/c was set and despite how much we played with the ceiling vent cover. We even had the a/c company come out, and they didn't find anything wrong and couldn't figure out why it ran warm. We don't have this issue with either of our two bedrooms upstairs or any other room/ space in the house.
During Hurricane Ian, we heard gusts of wind (sort of a whistling sound) coming from upstairs (where this room is located). And, there were a few times where we heard a loud gust, and, when I went upstairs, each time the attic entry cover had been blown ajar. (The attick entry cover is is about 3 - 4 feet from the bedroom doorway and about 15 feet from the nearest window in that bedroom. The cover had sort of been blow upwards towards the attic and off, so that some insulation dropped down.)
During this recent cold spell, this bedroom has been running very cold.
Our builder - naturally - has been slow, noncommunicative, and reluctant to come out and fix any of our issues (despite their promises to the contrary).
Does this sound like a window seal issue to you? If so, do you have a sense of how difficult it would be to repair it?
