Written by Brett Linton

U.S. heating and cooling equipment shipments continued to increase through June, up 6.4% from the month prior to 2.32 million units, according to recent data from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).

This is now the highest level in SMU’s history, surpassing the previous high of June 2020 at 2.28 million units. June levels are up 1.6% from one year prior, and this is the 13th consecutive month that shipments have increased on a year-over-year basis.

As a three-month moving average (3MMA), total heating and cooling shipments rose 27.2% year over year, the second highest rate seen in SMU’s 12-year history. May 2021 holds the record high 3MMA annual rate of change at 31.9%, and the record high prior to 2020 was 16.6% in February 2015. As shown in the chart below, June marks the 12th consecutive month that 3MMA shipments have increased on a year-over-year basis. 

Residential and commercial storage water heater shipments increased 8.3% year over year to a combined 913,213 units in June; 889,919 units were shipped for residential use and 23,294 units for commercial use.

June shipments of warm air furnaces totaled 327,412 units, an increase of 1.2% compared to the same month last year.

Central air conditioners and air-source heat pump shipments were down 3.4% from levels one year ago to 1,075,383 total units; 682,825 air conditioners and 392,558 heat pumps were shipped in June.
