Pay off & care for AC at old home

I am Alin S I have Rett Syndrome and Cerebral Palsy and am homebound. Although I moved out of this house for now due to my parents dog and other issues of developmental nature and need for space. The house is intended to be given to me when they no longer can use it. So we did it ourselves, because the old system failed before funds could be raised. My parents are now struggling to make payments on a high end system that is currently helping their poor respiratory health and when I acquire that home will hopefully still be there working for me. Let's raise funds to finish paying it off and ensure optimal care of this vital piece of equipment to my original home.
