I remember when air conditioner was slow to change.
When I was a kid, there was pretty much only a single kind of cooling system, and that was window cooling systems.
I remember when all of us got our first window cooling system unit, and it was amazing! The two of us all gathered around it care about all of us did our fireplace in the winter, and all of us just loved the cooling effect, then a long time later, all of us l earned about central heating and cooling. It took a long time, but all of us eventually upgraded the window cooling systems with a central cooling system. It was incredible to us kids because all of us could just go about our normal lives nnd be coolut having to cram together in front of the tiny cooling system blower. The series of ducts and cooling system air vents seemed ingenious to me, and honestly it still amazes me that some person with a correct brain thought of itâ€¦ NOw, though, correct aged central heating and cooling has been upgraded by Heating, Ventilation & A/C with zone control; Heating and cooling that comes with zones is all the rage, but in fact, there is a lot of other Heating, Ventilation & A/C technology that has improved energy efficiency and comfort levels, as well. Anyway, I am now flabbergasted by this zoning system! My brothers both have Heating, Ventilation & A/C with zone control in their respective houses. They use a single Heating, Ventilation & A/C unit, but the HVAC duct has something called dampers. The dampers are set up to have different zones, and they can adjust the control device settings to different temperatures for the different areas. It’s amazing, and I am sure a single day Heating, Ventilation & A/C technology will improve so much more, that it will seem aged school.
