Why is Central Air so important to many people ?The house I own now is very well built. Aside from the Attic, it stays naturally cool unless its 100 degrees.I live in SE PA.I do have window units. They keep things incredibly cool on a humid sticky day. Just one little unit cools the whole living room /dining kitchen (an area that is 35 by 40)My house is very old and it would cost around 15 k to install central air.Is it really that important to people ?
