Any experience comments welcome. |
We had an enclosed lanai BUT it was "conditioned" by having two vents added to the existing AC duct work. I thought the electric bill was still fine. We even kept the doors to the main house open. We only had to close those main doors a few times during the year on very hot or very cold days. We moved from that house and have an enclosed lanai and would just add additional duct work if we needed it. However, we just leave the doors open to the main house and the lanai stays comfortable.
My thought would be try the "leave the doors open" approach and see how that works. If still not comfortable, run ductwork (probably two vents would do it). The vents can be adjusted to allow for more or less air volume. I think the additional vents would not be cost prohibitive if you felt like a mini-split was necessary in the future. At least get the estimates.
