Through The Wall Air Conditioner Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Midea is the best-performing through the wall air conditioner brand in July 2026, moving 12,000 units across 4 ASINs for 76.9% of Top 10 volume. Profile follows with 1,000 units (6.4%), ahead of GE on 900 units (5.8%).

With 6 brands splitting the Top 10 and 89.1% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $134.40 to $394.00, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0DK639ZH9 booked 900 units at $134.40. On the growth side, B0CHZ5M5JB leads positive momentum with ▲ 600.0% MoM growth on 700 units, with B0F8XBV7VG close behind at ▲ 200.0% MoM on 300 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
