I am always pleasantly surprised to learn about something new.
There are so many varieties of things that I never even knew. I used to think that there was only one kind of air conditioner. In my house when I was a kid, I was only familiar with the window air conditioner. Those air conditioners could plug into a regular outlet and put shoved through a window. You could cool each room of your house individually, and you could even move them around if you wanted. Later, when I went to a friends house, I noticed that their house was cold, but I saw no air conditioners. I asked them about it, and they told me that they had central air conditioning. This hooked to their vents for their furnace, and it could cool their entire house without any windows being used. Last week, I learned about a new kind of air conditioner. This air conditioner was called a ductless mini-split air conditioner. It mounted high on a wall and was out of the way. This air conditioner required a lot less installation than central air conditioners, but they were individual units in every room, which meant that you could manage the temperature. The coolest part about this air conditioner was that you could also use it as a space heater and air purifier. One I heard about this, I called an HVAC company and asked them to replace my window air conditioners with ductless mini-split air conditioners. My old air conditioners needed to be replaced, and this seemed like a great idea!
