I hear lots of people talk about the basic necessities of man, such as: food, drinking water, shelter, etc. I feel that in our modern society, the number of basic necessities has grown to incorporate things, such as: WiFi, electrical power, running water, music, art, television, air conditioning, and more. We, as human beings, have changed very much within the last several decades. We have fantastic technology at our fingertips in every part of life. Technology can make our regular tasks so much less difficult! Part of me thinkg that the open availability of technology makes us quite a bit softer than we were a hundred years ago. After all, we now support companies who are specially focused on helping us heat, cool and ventilate our homes. My father is licensed as an HVAC technician. The basic human requirements used to center around simple things like shelter, which was a basic roof over your head. In modern day, a house wouldn’t be considered adequate without including a state-of-the-art HVAC unit. It is really wonderful how we have evolved our technological upgrades to add furnaces and air conditioning units. Our furnaces were once just fireplaces with open flames. Our air conditioners were as basic as just opening all of the windows. You will not catch me complaining, though! I think there is nothing as wonderful as the capacity to contact my HVAC provider and request service from them. They arrive at home and take care of my HVAC system whenever I need them. Current HVAC businesses now benefit greatly from our need to be reliably cool and toasty warm all year long. It is an interesting realization for me. I am totally dependent on my HVAC system, but I guess, everyone wins. My HVAC technician earns a full time income off of my temperature control needs. And also I keep warm in the winter because I have a modern and efficient furnace installed.
