Frequently Asked HVAC Questions

What is modulating heating?
A high-efficiency gas furnace with modulating gas valve and variable-speed blower provides outstanding efficiency and economical heating performance. Unlike single-stage gas furnaces that operate 'all ON' or 'all OFF,' a modulating, variable-speed gas furnace is designed to minimize energy use by running at its low fan speed setting to meet the temperature you selected at the thermostat or control system. It produces the right amount of heat to help maintain a steady, comfortable temperature inside your home.
