Many years ago when central heating and air conditioning was first coming around and becoming a known thing, some people said that it would not last because of how expensive it was.
When central heating and air conditioning first came around, only businesses and the very rich could afford to even have central heating and cooling.
However, sometime in the 1990’s they jacked the prices of central HVAC units down so that the average working class person could afford them. And this was the turning point in heating and cooling history that ensured that central heating and air conditioning systems were most definitely here to stay forever. Of course of the years with the advancement of heating and cooling technology there has been many developments in central heating and air conditioning that have made the HVAC systems much better and much more powerful. They even have zoned HVAC systems which is alternately known as HVAC zone control. That is where you can have different thermostats in every room in your home and have the temperatures be different all over. This is an expensive type of heating and air conditioning system. However I have faith that some day these too will go down in price and be a common option for the average working class consumer to chose from when they are looking to buy a brand new and up to date central heating and air conditioning system unit. What does tomorrow hold? Who knows, but all I do know is that central heating and air conditioning is here to stay!
