Have not looked into thermal because HOA has rules against it (which a few families are fighting to get changed).
Even looked into geo-tehrmal, but the installation costs are a lot more than we can afford at this time. Even if we don;t go with the 'hybrid' solution, the furnace we are getting is more efficient than what we have - current is about 80% - though both HVAC guys we had give us quotes said that functionally, its probably less.
