    My friends have 2 mini split heat pumps that could not keep their 1600ft² cool. So they bought 2 $100 window units from home depot. Their energy use dropped $300/mo. Or at least, the energy equivalent. They’ve got solar and dont pay for their electricity.

    The window units use less energy and keep their home cooler.

      The magic of an inverter system only happens at lower load. If they’re undersized, they run full tilt at minimum efficiency.
