Install an Additional HVAC System
Most sunrooms don’t have dedicated climate control systems, and that is why they aren’t always usable once the weather cools off. Instead of trying to redirect your duct system and add new vents to the sunroom, you might want to install its own heating and cooling system. A ductless mini-split unit is a particularly good option for smaller rooms that don’t have enough insulation. One of those units should be able to increase the temperature inside your sunroom by multiple degrees in a matter of moments.
Update Your Furniture
Using metal or plastic chairs in your sunroom might not be a bad option during the summer, but that furniture is going to be frigid once the weather starts to cool off. If you have noticed that your current chairs seem particularly cold, then you might want to switch to wicker chairs. A high-quality wicker chair is going to be comfortable, easy to maintain, and very durable. Those chairs also come in a wide variety of styles and colors, and you are sure to find a set that complements the rest of your décor.
Upgrade the Windows
Your sun room’s first line of defense against the elements is its windows, and low-E glass windows are usually the best option for any structures that are in cold climates. At the very least, you should consider adding low-E coating or some other type of insulating film to all of the windows. That extra layer of insulation could increase the temperature inside the sunroom by multiple degrees.
(Low-e stands for 'low emissivity', which results in improved energy and efficiency of windows.)
Put Up Thick Curtains
Even high-efficiency windows are going to allow some heat to escape, and that is why you might want to put up thick blinds as well. Those strips of fabric are going to minimize heat loss and greatly improve the overall efficiency of the room. They can also easily be taken down once the weather starts to warm up.
Another simple upgrade that is going to make your sunroom more comfortable during the winter is a heavy rug. Many sunrooms have nothing more than concrete floors, and your feet are probably going to be freezing if you don’t put some type of carpeting down.
