too cold downstairs/too warm up
I am having trouble regulating the temperature in my two-story home. Getting the upstairs area to a comfortable temperature means freezing out the downstairs. Even with ceiling fans, it gets pretty warm upstairs. I had originally closed off most of the ducts downstairs to help regulate the temp. better, but my Dad says that can cause damage to the duct system. Is there a low-cost solution to this problem? Any advice would be greatly appreciated.
