So I own a house built in 1985 and the HVAC just went out. I’m active duty military and looking to maximize value of what people consider valuable when buying a house around here as I won’t be in this house much longer. Here is my situation….

I bought the house and it was all electric. I have since had gas installed when I had my hot water heater upgraded to a gas tankless. My question is…. Is it worth it to upgrade to gas heat vs heat pump. I have a dual zone system and the upstairs of the house would need to stay heat pump but I can get gas installed for about $4k more. Will I see the return on investment in this area when I go to sell later this year?

Additionally, the only other “need” I would consider on the house is replacing the original windows. Is replacing the windows a good return on investment as well or just let it ride? There are 12 windows on the house plus a large bay window.

Thanks in advance for the insight if you all can help.
