I have an connected lanai that is all screened, this should be an awesome room in the house; Instead it is a hot, sticky mess.
The screens let in all the muggy, moderate air in the summer, and closing the screens makes it hotter when the sunshine comes in.
In the Wintertide the cold seems to linger there. The space is basically unUSAble. It is wide, long plus has a wonderful view. I would appreciate the lanai to be a labor out room or at least hang out space for our family. I need to find some way to have superior weather conditions control, eventually I assume 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 plus cooling plus only labor in that a single space. I could have superior cooling when the tepid sunshine comes through the windows in the summer. I then could change it to quality heating when the Wintertide cold comes in. The space could be used all year with good Heating plus A/C equipment. I don’t assume it will be too extravagant after the initial Heating plus A/C installation. Anytime I use the space I will turn the Heating plus A/C on; When not in use, I can simply power it down plus let it be tepid or frigid cold. A smart thermostat would make it so I don’t even have to walk in the room to do it too.
