I live up north where there are 4 distinct seasons every year, however hands down Winter is typically the most extreme. Even the most intense summer time heat waves in this region have nothing on the sheer insanity of the cold snaps every one of us get throughout January & January. I have a wood stove & find myself going through several cords of wood in the full Winter season just to heat our small little house. That’s quite a big volume of wood to have piled in your garage for 4 weeks out of the year! This gets me through Winter until the snow thaws & the sunlight intensity starts to rise as the sun’s rotational angle begins to shift again. Most of our friends & neighbors neglect to use air conditioning 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 bills in the summertime if it means preventing destructive mold growth in our 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 Heating & Air Conditioning plan in the quality of the air that you breathe into your lungs every hour of every day. Your air conditioner filter alone catches a considerable amount of dust & pollen that would otherwise circulate in your air & collect in your lungs. Add-ons enjoy air cleaners, 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 clean indoor air.
