I've been looking around this forum and some others as well, and I hope I find some knowledgeable advice here. I just purchased a home w/o AC and with floor furnace. so we want to update all of it because it can get super hot and mildly chilly. The house is about 1200sq. How big of a/c and heating unit should I look for? Also, disregarding location, how expensive can it get to get this project completed? I'm pretty handy, but I think this job will be over my head to finish properly.
Thanks in advance!
