I have a legitimately terrible and unanticipated effect that happens to the mirror in our powder room in my master bath.
This happens every single time our central heating plus cooling system plan seems to have turned on, when the cooling system or the heating comes on, our master bath mirror ends up fogging up! It is kind of love when you are in a super long and hot shower with the door closed.
The mirror does this typically without any provocation! When it first started happening I thought I was losing our mind or something was going on, however, it was clear when me or our partner did not just take a shower. It took about a month and a half to figure it out, however but after that I noticed it was when the overhead air vents started pumping out the heat or the cooling system. I don’t remember that it ever did this before. The reason for it was also unquestionably odd, in the end. It turned out that there was something else going on. It seemed to me that there was some kind of steam coming out of the air vent. We eventually figured this could be a disappointing issue so we called the local heating plus cooling system dealer. They sent out 1 of their certified heating plus dedicated certified cooling system specialists. When they looked at everything around the house they found that there was some kind of small issue with the air ducts in our home. The outside air was combining with the air from the high powered central heating plus cooling system unit. This is what was causing the unwanted steam! The answer was to get the air ducts plus the air duct sealed properly. This was going to cost us some extra cash obviously. But in the end it was something we had to do.
