I live in West Texas, sort of dry, in a home built in 1969.
Central air/heat is all electric (no heat pump)and about twenty years old. I need to rework the whole house as to energy efficiency. I found this site, thank goodness. This whole area is confusing and getting good advice is a little difficult. I have two questions that I need help with:
1. What elements of the house (windows, doors, attic, ductwork) do you see as most critical? I am particularly wondering about the attic and ductwork issue. Also, is window replacement essential? (it is expensive).
2. Is it a no-brainer that the central unit needs to be replaced for simple cost-efficiency matters. It is working okay. Cooling is the big issue down here, but winter bills for the electric heat can get expensive though it's a short season.
Thanks so much,
