There is way less mold and we are so much happier
When my boyfriend and I moved down south we thought central air conditioning was not necessary. We lived in the north our whole lives and had never owned a cooling system. The southern weather is much hotter and starts earlier. So we decided that getting some form of cooling would be a good idea. My boyfriend and I bought window air conditioners. One for the bedroom, one in the kitchen and one in the living room. With three cooling devices all working together, the house should be cold enough. Well we were wrong on that. The southern weather does get really hot, but the real pain is the humidity. The window cooling devices had trouble with the heat, but the humidity lingered in our house. Combining the pitiful cooling and warm, moist air from outside was bad. Condensation formed on the AC devices, on our walls and around the baseboards. I was constantly cleaning up mold and stropping future bacteria growth. The house was not the right temperature and running those devices was so much in electric bills. We finally chucked the cooling units to the curb and got central air conditioning. Wow, what difference with the whole home being cooled. Also the air conditioning is naturally drying out the air and taking care of the humidity. There is way less mold and we are so much happier. If someone came to the north and only used space heaters, they would be in for a rude awakening. I guess this is what happened to us only with AC in the south.
