What is two-stage cooling?

When a cooling systems has two-stage cooling, it means that there are two levels of operation. This lets the system work as efficiently as possible since there is one level for milder weather and one for harsher weather that demands the system work harder. Two-stage cooling also enables almost unnoticeable temperature changes so you don’t experience extreme differences in temperature. Aside from better efficiency, other benefits of two-stage cooling include quieter operation and better humidity control.
