I read on here that it’s a super easy to do by yourself so Im thinking of getting a kit off amazon. If anyone here has done this themselves or is familiar with the process I would appriciate any advice before I get started. If you have purchased a kit for this could you link it down below or let me know where it was purchased at. And for those of you who have done this how significant were the changes in tempature in your house? My second floor gets really hot with the AC off so I’m hoping this will help.
