US shipments of heating and cooling equipment slipped in September for a third consecutive month, according to the latest data from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). Shipments declined 2.6% month on month (m/m) in September, after having fallen 10% m/m in August. The monthly pace marks the third-slowest shipment rate year to date.
Historically, shipments are strongest in early summer and weakest around the turn of the year, driven by seasonal air conditioner and heat pump volumes.
AHRI's data shows September shipments totaled 1,687,240 units, down 2.6% m/m but up 7.7% year over year (y/y) (Figure 1, left). From August to September, shipments of warm air furnaces, A/C, and heat pumps declined, while water heater shipments rose. Compared with a year earlier, only air conditioners and heat pump shipments were higher.
