One of my 3 geothermal heat pump/condenser units has failed. Original installation was in 2011, in my primary residence. I'm evaluating whether to fully replace it with a new, 2024 model, or spend about half that cost to repair it. My current situation is I have two heat pumps operable. If I either replace the third unit, or repair it, is either ( or both?) considered an improvement from my current situation, whereby I choose again to go geothermal? And therefore make me eligible for the 30% tax credit?
Thanks
