I find this quite interesting

My spouse, Mark, and I have consistently lived way up north, along the border.  For the majority of the year, both of us deal with extremely cold weather, feet of snow, sub zero temperatures, and vicious wind chill.  Mark and I have a oil furnace installed in the house, and both of us spend a fortune on our heating bills, we’ve never bothered with central a/c.  After nearly thirty years, both of us got exhausted of shoveling snow, scraping ice, and relying on the oil furnace to keep us comfortable. We decided to invest in another house, down south, where both of us can spend the Winter seasons.  He and I soon realized that houses are quite different in the south. None of the houses we looked at had basements, however they didn’t feature insulated windows, and most of them were constructed from cement block. The house that we finally chose has a good sized yard, however the dirt is mainly sand.  There are tall palm trees and big cactuses in the garden. The most significant difference between our several homes is the Heating and A/C system. In the house down south, the system offers no heating capacity whatsoever, and the a/c unit is enormous. The component is located outside the house, exposed to the elements, and links to air duct.  I was stunned by the diameter of the air duct. The overly big air duct takes up the entire attic crawlspace. It also provides a great deal of cold air. The cooling system is capable of cooling down the entire house abruptly. The cooling component can handle tremendous heat and humidity, and maintain a comfortable indoor temperature. I have switched to worrying about electric bills due to the a/c, rather than oil bills from the furnace.
