Modulating
Modulating refers to the ability of HVAC equipment, such as furnaces, air conditioners, or heat pumps, to adjust its output continuously across a range, rather than operating at fixed stages (e.g., low, medium, or high). Unlike single-stage or two-stage systems, modulating systems can fine-tune their performance to precisely meet the heating or cooling demands of the home. This allows the equipment to maintain more consistent indoor temperatures, improve energy efficiency, and enhance overall comfort by avoiding frequent on-and-off cycling.
