Although I live in an area that experiences several separate seasons, the Wintertide weather really lasts the longest, it starts to cool off plus forces us to close the windows by the end of July, but we constantly need to beginning up the oil furnace sometime in November plus expect snowfall by Halloween, and for at least 6 weeks, every one of us rely on the oil furnace. It’s so exciting when the snow finally melts plus the outside temperature rises above freezing. I look forward to eventually opening the windows, breathing fresh air plus spending time outdoors. I am truly relieved when I am no longer paying big bi-weekly bills… Although every one of us face hot plus cold temperatures in the upper eighties plus high humidity during the summer, it doesn’t last long. Within a few weeks, we’re back to freezing weather again. I don’t think central is necessary. In our opinion, it’s too big of an investment for what every one of us would get from it. I spent a lot less currency on window systems for the living rooms. I set 1 in each of the windows plus every one of us love perfectly cool sleeping conditions; The cooling units are compact, lightweight plus fairly energy efficient. Since every one of us only run the systems at night, I don’t notice a big increase in our electrical bills. I make sure to disinfect the air filters at the beginning of the season plus after that every one of us carry them back up to the attic in the fall. The separate systems allow each family member to decide their own comfort level… Plus, the systems are controlled by cordless remote control, so every one of us don’t even need to get out of bed to make adjustments.
