My 2 story house has a single zoned A/C (and heat). It is not a problem now with four people living in it (2 parents, 2 kids). My kids are leaving for college this September. Most of the time, my wife and I will be downstair during the day, and upstair for sleeping at night.
What is the CHEAPEST (material and labor) way to hack the system so we can cool/heat only the needed portion of the house? Has anyone attempted this? Thanks.
