If you intend to hold onto the property, or are just inclined to do your rehabs correctly, get a unit that is properly sized for your ducting and sq footage.FHA HVAC equipment that is oversized for the installed ducting is prone to shorter life span due to short cycling and potential cracks in the heat exchanger since the ducting will not allow the proper amount of air to be moved across the exchanger.
