When you have two people living in a beach home that have truly peculiar ideas of what temperature on the control unit constitutes being comfortable, it can be hard when you can only set one temperature within a home, then somebody’s preferences win out over the other’s preferences, it’s that easy, and or, alternatively, there is a constant confrontation over control of the control unit. Me and my husbandy used to have that problem to some degree. We were not aware that there was a easy solution, and that easy solution was zone controlled heating and a/c. It turns out that you can indeed compartmentalize your beach home in terms of the Heating and A/C, and set peculiar hot and cold temperatures for peculiar zones of the home. Special air dampers that restrict, increase, or redirect airflow make this a opening. Once the dampers are installed, you can install separate control units for the peculiar parts of your homeâ€¦ Now, the only time the temperature on the control unit is called into question is when myself and others and my husbandy are making a point of spending time together in the same room. At the least, with zone control heating and air, we can both be quite comfortable when we are having our own private time. Not to mention the fact that we no longer have to heat or cool an entire home when we want to be comfortable in a unique room, however for example, if I am in my study writing on the ipad, and my husbandy is out with his mans, I can turn up the heating or air in the study and have the rest of the home shut down! Pretty convenient, huh?
