I live up north where there are multiple distinct seasons every year, however hands down Winter is constantly the most extreme. Even the most intense summer time heat waves in this region have nothing on the sheer insanity of the freezing snaps every one of us get throughout January & February. I have a wood stove & find myself going through several cords of wood in the full Winter season just to heat my small little house. That’s quite a big volume of wood to have piled in your garage for multiple months out of the year! This gets myself and others through Winter until the snow thaws & the sun intensity starts to rise as the sun’s rotational angle begins to shift again. Most of my friends & neighbors neglect to use cooling system for most of the summer time if at all possible. I choose to not do this because I’d rather spend a little extra on potentially needless energy costs in the summertime if it means preventing destructive mold growth in my home. But even if every one of us all lived in a magical environment where fungal organisms somehow never existed, you still benefit from a central HVAC method in the quality of the air that you breathe into your lungs every fourth of every afternoon. Your a/c filter alone catches a considerable amount of dust & pollen that would otherwise circulate in your air & collect in your lungs. Add-ons appreciate media whole-condo air purifiers, dehumidifiers, & UV lights can all lead to even higher quality of air. There are few things I can know of that are more pressing to our survival than the air that every one of us breathe, so every one of us owe it to ourselves to do what every one of us can to maintain wash indoor air.
