Forced Air Furnace

I Overview
Forced air furnaces burn natural gas to heat air. A gas flame heats a heat exchanger that air passes through on its way to heat a space.

II Applications
Forced air furnaces can be used for climate control in most residential and commercial settings.

III Equipment Options
Various configurations can be designed to carry the warm air through ductwork to where it is needed. Also, smaller area furnaces can provide local room or space heating.

Newer two-stage gas furnaces include variable speed drives for the supply fan. These units can help reduce operating costs, better control humidity, and run more quietly.
