Back when i was a teenager, my friend’s parents had central air conditioning in their home. Every time i would go to visit them it was shocking to go from the hot humidity in the outside air into the freezing cold treated air of a house with central air. It turned out refreshing to feel the sweating on my cheeks immediately dissipate at the touch of that cold, highly purified air. They had the temperature set so low i always froze when I was in their house. That is not enjoyable when it’s 85 degrees outside. All I can think about if it is warm is how warm it is, and I never want to be cold. Central air is fantastic when it’s hot out. Having the power to make your house as cold as you would like can be magical. I enjoy the warm summer season so much that I don’t want to be shivering in a sweater when the sun is out and I realize that winter is inevitable. Having your HVAC system running all the time like they did, must call for a lot of maintenance and repairs as well as high energy usage. The HVAC system in your home should make your life in your house more pleasant. Obviously some people prefer cooler temperatures over hotter ones, but I am not that type of person. What I look for in the air conditioner is something that will cool down my house, but not to the point that it is cold. Comfort is certainly key on the subject of heating and cooling your household. If you like to be cold, a central air conditioning system on full blast is probably the path to take.
