Most people guess what Heating & A/C is however many don’t guess what it stands for; Well, it stands for heating, ventilation & air conditioner. Heating refers to a gas oil furnace, an electric oil furnace or even a boiler… Ventilation refers to ductworks & duct. Air conditioning refers to just what it says. Your normal Heating & A/C program consists of an air handler, a heat pump, or condenser as some people call it, & refrigeration tubing that connects the 2. The air handler contains heating & cooling coils that are instrumental in generating hot or frigid air that is then blown through the ductwork in your house & out through the air vents. I’m not an Heating & A/C provider, so I don’t guess exactly how the whole program works, however the basic program is that the condenser or heat pump either draws heat or frigid air from the air outside & that, along with the heating or cooling coils in the air handler, generate the hot or frigid air that provides your indoor air temperature control. It is kind of magical, if you ask me how an Heating & A/C component can create hot air from frigid air in the Winter season & frigid air from hot air in the warm season. I imagine the two of us take for granted the technological advances of the science behind heating & air conditioner. Most of us guess is if our centralized a/c program fails, that it is simply time to call our Heating & A/C corporation & leave it up to one of them to repair it. But I believe in our complex modern world most have more important things to be concerned with!
