I’m in my 40s, single and I make a lot of money. I need things to spend my money on that I enjoy. Recently I decided to add an addition onto my home. I added a whole other room and just made it my library. I had tons of old book collections that I wanted displayed. I got the old fashioned library bookcases to hold them. I even made a window seat that I can sit and read while looking outside. The room is now my favorite one in the house. The issue is that when the room was added on, I forgot about HVAC. I have a central heating and cooling system that utilizes ductwork to give whole home temperature. I did not have the air ducts extended and installed in the library. So now I am out of luck for climate control. I can’t use my current HVAC unit, I would have to buy and install a different one. I can’t go without HVAC in my library either. The books are very susceptible to poor air quality. It doesn’t matter if the indoor air quality is dusty, more so if there is moisture. Too much moisture in the indoor air quality will cause water spots and mold. My books would all be ruined. A dehumidifier would work, but installing one with an air conditioner would be better. I have been loosely thinking of getting a ductless air conditioner for the room. I then could set up the humidifier to work with the AC. In the summer I could sit in the window seat with the sun pouring in and it wouldn’t be an issue at all.
