My 14 year old ac unit went kaput. Definitely gonna replace it but was looking into the new energy tax credit and was told that in order to qualify, a new furnace would need to be installed as well since my current furnace is 80%.
As my furnace is also 14 years old, this might be a good time to change it out although it currently works fine. I would probably move the existing furnace to my detached garage and use it there. Am I required to update my furnace also in order to get the tax credit?
