Thank you for your help. In 2010 we installed $10,600 worth of windows. at the time $1500 was the energy credit, which was nice. In 2020 we purchased Heating & Air conditioning unit at $9,440. My question, is the $1500 my forever life time credit or are windows capped at $200 and $500 credit for Heating and Air conditioning leaving $300 credit for this year. Or is that wishful thinking?
