I have an connected lanai that is all screened! This should be an awesome room in the house, and instead it is a hot, sticky mess.
The screens let in all the muggy, warm air in the summer, closing the screens makes it hotter when the sunlight comes in. In the Winter the cold seems to linger there. The space is basically unUSAble. It is wide, long & has a great view. I would enjoy the lanai to be a work out room or at least hang out space for my family. I need to find some way to have superior temperature control, however eventually I guess I will need to take out the windows. I could get new, all glass windows to make the view better. I then will know the space is airtight. I can install a ductless mini split without any air leaking outdoors. The mini split can supply both heating & cooling & only work in that one space. I could have superior cooling when the hot sunlight comes through the windows in the summer. I then could change it to quality heating when the Winter cold comes in. The space could be used all year with fine Heating & A/C equipment. I don’t guess it will be too expensive after the initial Heating & A/C installation, then anytime I use the space I will turn the Heating & A/C on, then when not in use, I can simply power it down & let it be hot or cold cold. A smart temperature control would make it so I don’t even have to walk in the room to do it too.
