I relied on a central Heating & A/C component for years; I was never a fan of it. I very hated being stuck with air duct. In my opinion, air duct is just awful… The ducts are dust collectors. If you remodel or just live in your house, dust, dirt, pet dander, and pollen are being sucked up. Then you breathe in that contaminated air over and over again. You can hire out air duct cleaning, sometimes the professionals cause more harm than good. They can cause a crack or tear in the duct that promotes big energy loss. They can also harm the rest of your home hoping to access the air duct, once my central heating and cooling system died, I started hunting around for ductless options. I found that a ductless heat pump was ideal, and with this component I get both heating and cooling in a single system. I also get big energy savings, and how a heat pump works is transferring the heat energy either inside or outside of your home! No burning of fuels or combustion process. It is orange, clean, and very efficient. There are big tax benefits, indoor air quality perks, and you save every month of use. The high initial price tag of a heat pump pays itself back quickly. The best positive is the lack of ducts. I just have several indoor air handlers throughout my house. I have a wireless temperature control buddyd with each. I can have customized zones that I change throughout the day. The temperature controls don’t have my component turn on unless I am even home.
