I'm evaluating two proposals for a home mini-split HP system. One proposal using Fujitsu units says I don't need backup resistance heat strips. The other proposal for a Lennox-based system insists on adding heat strips. Weather in my are seldom gets down ot the 20s, but we have plenty of days and nights in the 30s. I'm wondering if there is a difference in the technology used in Japanese brands versus that used in some American brands?
