Portable AC with Heat Pump function
Instead of building your own heat pump you can buy portable AC units with this feature. I have Amcor 12000BTU portable unit (ALD12000EH) that we use wintertime to heat up our bedroom. (So other part of the house isn't heated much while sleeping.) This did reduce our combined gas and electric bill significantly. The only downside is that the unit is rather noisy... but you get used to it.
