I may be in the minority, but I am one who likes the old school ways of heating and cooling my home.
I have a gas furnace which takes care of all my heating needs in the winter months of the year, and then in the summer I have a huge window air conditioning unit to take care of my downstairs area, and in the bedrooms I have regular small window air conditioning units. These all do me just fine. Also by going old school like this it makes it so that maintaining things with the heating and cooling are a lot easier and cheaper than having to go through all the headaches that come with having central heating and air conditioning systems. I do not have to ever really think about heat and a/c tune ups and check ups. The only air filter I really ever have to change regularly is in the furnace, and even that is a lot less frequent than you have to do with central heating and air conditioning systems. And the biggest perk of going old school with my heating and air conditioning is the fact that my monthly electric bills do not skyrocket and make me go nearly broke like many others I know. When you have a gas furnace and window air conditioning system units, it makes it so that not as much energy is used to keep your home warm or cool. While with a central heating and cooling system this can really hike your electric bills to sometimes five hundred dollars a month if it’s during a cold front or major heatwave. I am totally happy!
