When preparing for the drastic parts of the year north being Winter & south being warm season. There is a lot of preparation that takes locale that is similar & then there are things that vary greatly. One of the things that is similar is that either up north or down south you must make sure your HVAC program is running properly before the most critical parts of the year such as below frigid rapidly increasing temperatures & snow or hottest area of the warm season; Making sure that you have it serviced & took care of throughout the year helps. In the north you must make sure you have fire wood chopped if you have a fireplace & gather items for when you are snowed in, and down south you must make sure you have your hurricane rations together & plenty of water in case you can’t get out of the house after a storm… Either way you look at it there is preparation for either north or south & it doesn’t have to be a chore if you do a little at a time. Whether you are using a oil furnace or an A/C 1 of the most crucial things is to make sure it gets took care of & that if it has a filter that the filter gets changed once a month & make sure there is gas or oil for the oil furnace. If you keep those things current & done throughout the year then there will less of emergency troubles down the road. So it doesn’t really matter if you live up north or down south being prepared is vital to both.
