Shipments of a/c units and heat pumps fell in November 2025 compared to the same time last year, while furnaces saw modest year-over-year gains, according to the latest report from the Air-Conditioning, Heating & Refrigeration Institute.
The report also shows residential storage water heater shipments remained relatively stagnant in the same period.
The shipment totals are indicative of the overall soft demand in the residential cooling market. As Carrier CEO Dave Gitlin said when acknowledging the slowdown: “It goes without saying that in the second half of [2025], the [residential] business experienced significant weakness. And a key question is, what will this business do next year?”
Air Conditioners and Heat Pumps
Shipments of a/c units and heat pumps have once again plummeted. The following are the totals for November 2025 compared to the same time last year:
Air conditioner units and air-source heat pumps: 379,470, down by 46.4% compared to 707,436
Air conditioners only: 181,223, a decrease of 53.7% compared to 391,531
Heat pumps only: 198,247, down 37.2% compared to 315,905
Stacked against October 2025’s shipment totals, about 8% more a/c and heat pump shipments were made compared to November. In the same vein, the a/c-only shipments from October to November decreased 11.3%, and heat pumps by 5.7%.
AHRI data shows this is the sixth consecutive month for both products to have lower year-to-date totals than in the same period last year.
Year-to-date totals compared to 2024 were:
Air conditioners and heat pumps: 7.34 million, down 19.9% from 9.16 million
