Majors and Comfort Conditioning Appliances

Index reflects monthly factory unit shipments of major and comfort conditioning appliances as reported by AHAM, ARI, and GAMA, including APPLIANCE magazine estimates. Due to a change in reporting procedures at GAMA, totals for cast iron gas boilers, steel gas boilers, cast iron oil boilers, and steel oil boilers will no longer be reported monthly, and will instead be reported on a quarterly basis.
