Can I keep my existing ducts for a variable‑speed heat pump without re‑sizing?

Yeah, maybe, but only if your ducts are big enough for the new heat pump. These pumps push air slower to save energy, so small or leaky ducts can mess things up. It’s best to double-check with a duct test before you use the old ones again.

Yes you can depend on how it still works
