White House Cuts Section 232 HVAC Tariffs From 25% to 15% Through 2027

Tariffs on imported residential HVAC equipment dropped from 25% to 15% on June 8, after a presidential proclamation signed June 1 expanded the reduced Section 232 rate to cover air-conditioning machines, parts of air-conditioning machines, evaporator coils, and heat pump components built predominantly for residential use. The cut is temporary, running through December 31, 2027.

That's a 10-point swing on equipment contractors are buying right now, at the front edge of cooling season.

The proclamation adds the HVAC subheadings to Annex III of the Section 232 derivative tariff structure, the same mechanism the administration used to trim rates on agricultural and mobile industrial equipment in the same order. Heating, Air-conditioning and Refrigeration Distributors International estimated the HVAC reduction alone is worth nearly $2.3 billion in consumer savings, ACHR News reported.

What the Tariff Reduction Actually Covers

The relief targets the steel and aluminum derivative duties that have been stacked onto finished residential systems and their key components. Evaporator coils made the list, which matters because coils are among the most aluminum-intensive parts in a split system and have carried the full 25% derivative rate since the metals tariffs expanded. Parts of heat pumps for air-conditioning machines are covered too, according to a client advisory from C.H. Robinson.

The order also loosened the domestic-content test. Products previously needed 95% U.S.-melted metal content to escape the derivative tariff. That threshold is now 85%, which should let more North American-assembled equipment qualify for preferential treatment.

Commercial-grade equipment didn't get the same break. The baseline 25% rate still applies to most derivative imports outside the newly listed categories, and a few products, steel racks among them, were actually added to the tariff list in the same proclamation.

Will Contractors See Lower Prices?

Don't expect the 10 points to show up on your distributor invoice next week. Wholesalers are sitting on inventory they landed at the 25% rate, and equipment pricing over the past 18 months has been driven as much by the A2L changeover and copper costs as by metals tariffs. We covered that dynamic when ACCA pushed back on the Section 232 expansion, and the math hasn't changed. Tariffs are one input among several.

Still, this is the first real tariff relief the residential side has seen since the derivative list ballooned, and it lands during the highest-volume buying months of the year. Contractors quoting replacement systems into 2027 should at least see increases slow. Our earlier reporting on how tariffs feed repair demand found that homeowners react fast when replacement quotes jump; the reverse trip takes longer.

The reduction expires December 31, 2027, at which point covered products revert to the prior rate regime unless the administration extends it. Customs and Border Protection is expected to issue guidance on the new content calculations and classification questions in the coming weeks. Watch the July price sheets, that's where you'll learn whether manufacturers pass the savings through or keep the margin.
