New tariff changes could shift Home Depot HVAC pricing and supply

Home Depot stores selling HVAC equipment are likely to feel the tariff shift where it matters most, on price tags, supply timing and the questions customers ask in the aisle. The U.S. cut the rate on certain residential heating, air conditioning and ventilation equipment from 25 percent to 15 percent, and some foreign-produced equipment can qualify for a 10 percent rate if its steel or aluminum content meets a strict U.S. melt-and-pour threshold.

The change took effect June 8, after a June 1 proclamation and a June 2 update from the Air Conditioning Contractors of America. The White House said the tariff adjustments are temporary and run through December 31, 2027. It also said the lower 10 percent rate applies only if capital equipment contains at least 85 percent U.S. melted-and-poured or smelted-and-cast steel or aluminum by weight.

For associates in Pro, appliances and installation-related roles, the practical effect is not abstract. HVAC pricing and availability can move quickly when trade rules change, especially for customers trying to compare a replacement unit, a full install or a contractor quote. ACCA’s tariff resource center said tariffs are already affecting HVAC supply chains and contractor customer conversations, with steel, aluminum and copper feeding into compressors, coils, cabinets, refrigerant lines and electrical components.

That makes sourcing questions harder to dodge at the sales floor. ACCA said most HVACR equipment relies on those metals, and it identified Mexico as the largest single exporter of HVACR products to the United States. In a store setting, that can mean more questions about where a unit was made, how long replenishment will take and whether a customer should buy now or wait for pricing to settle.

The backdrop is a broader metals campaign that has already raised the stakes. In April 2026, ACCA and HARDI warned that revised Section 232 metals rules could push HVAC equipment costs higher, and HARDI said late-2025 Mexico import data pointed to an effective tariff rate of roughly 8 percent under prior conditions. ACCA asked the administration for an exemption or a 90-day delay so manufacturers could adjust supply chains, underscoring how quickly the policy changes were moving.

The White House framed the June action as part of a wider Section 232 effort that also covered aluminum, steel and copper, including earlier April 2 duties of 50 percent on products made of those metals, 25 percent on derivative products and 15 percent on a subset. For Home Depot, the key question is whether distributors can reprice, restock and reset enough to keep the HVAC aisle moving without leaving associates to explain a market that is shifting underneath them.
