What is two-stage cooling?

When an air conditioner uses two-stage cooling, it means that there are two levels of operation. This lets the system work most effectively since there is one level for milder weather and a second for harsher weather that demands the system work harder. Two-stage cooling also enables slight 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 improved humidity control.
