I have an older home that lacks any type of ductwork, the walls are constructed of plaster which is horrible to tear down, and it crumbles and makes a large, dusty mess. Plus, the studs in the interior walls are turned sideways to gain more living space. This makes for especially narrow walls, which won’t accommodate traditional ductwork. For a long time, my spouse and I got by with many types of area furnaces and portable cooling systems. The people I was with and I weren’t ecstatic with this, then window cooling systems look really horrible. They are aggravating to install and cumbersome to store when not in use. Instead of whole-home cooling, the people I was with and I were living with a couple of cold cold rooms combined with a bunch of hot and sticky areas. During the Wintertime, the area furnaces couldn’t keep up on absolutely cold mornings. We’d huddle under heated blankets and just about freeze to death. I also sad about safety concerns and hated the ugly extensions cords stretched across the floor. I didn’t realize that there were whole-home solutions available that wouldn’t require a major renovation project. I finally did some research and came across 2 different options. There’s high velocity Heating and A/C systems which use very narrow diameter, versatile ducts. The ducts are able to be snaked into existing walls and fitted around obstacles such as electrical wires and plumbing pipes. The high velocity plan pushes air at a very high rate of speed to bring the room to a comfortable level abruptly. The other option is a ductless multi-split heat pump which links a single outdoor compressor with up to eight indoor air handlers. The ductless plan requires only a more than two inch-hole through exterior walls to mount each air handler. The people I was with and I chose the ductless heat pump, and the entire plan was up and running within a couple of mornings with very little disruption to our home.
