What is a 3 stage HVAC system?

A 3-stage system might have “low”, “medium”, and “high”.) Like a hair dryer or a ceiling fan, they have some granularity to their output. Multistage systems are more common in larger and newer homes, and are often found in regions with very cold or very hot weather.

What is the advantage of a variable speed air handler?

What are the benefits of a variable speed air handler? More consistent cooling.
