But wouldn't be better if people would invest in better home insulation and ventilation? It would help in the winter also. I say this because since the early 90s, my father installed air conditioning in our home, but in 2020 the building was redone (the building is from 1986), and whenever I return home in the summer, I don't need air conditioning. Just lower the roller blinds and open the windows after the sun passed.
