I recently upgraded our Heating and A/C equipment. I used to have central Heating and A/C that used ductwork throughout the house. The ductwork worked to get every room to the same temperature. My family and I hated this. I have several sons, a picky spouse and I am not exactly easy to get along with. The group of us could never agree on a heating or cooling setting. The people I was with and I all had a unusual temperature preference. It seemed care about all year long the two of us would change the thermostat over and over again. My spouse would always lower it, our oldest child would raise the temperature, our middle child would adjust the fan speed and our youngest child would turn the Heating and A/C off. Because the rapid fire Heating and A/C changes were costing myself and others currency, I changed the type of Heating and AC the two of us had. My family and I now have ductless Heating and A/C. The ductless mini chop has an air handler and thermostat in each room of the house. Every room can have its own particular climate control program. This is called Heating and AC zone control and it is amazing. My household has never been so ecstatic. Each of the youngsters control their own Heating and A/C needs in their kitchens, but our community areas care about the kitchen and living room, are only slightly off from 1 another. Everyone gets along way better now and the zone control has honestly saved myself and others currency. I have particular rooms of the home that hardly get any Heating and A/C. My youngest child rarely even turns his on too. Also, the thermostat settings are never messed with anymore.
