More than 20 HVACR manufacturers announced price increases effective across the month of July 2026, extending a year-long trend of multi-wave pricing actions that has made month-by-month price list management a standing operational requirement for distributors and contractors throughout 2026.

The July round follows a particularly heavy June, which itself followed January, April, and May rounds that collectively established 2026 as one of the most sustained multi-wave pricing environments the HVAC channel has experienced. The July adjustments span coils, motors, flexible duct, venting products, filtration, valves, PEX products, controls, and unit heaters — a cross-section of product categories that feeds into virtually every residential, light commercial, and commercial HVAC installation.

The July 1 Increases

Among manufacturers announcing increases effective July 1: Air Products & Controls announced item-by-item adjustments varying by product. Allstyle Coil Company announced a 3.5% increase on its product line. Diversitech announced item-by-item changes. Duravent Group announced a 7% increase across its full product portfolio, including products under the Duravent, Amerivent, and Builder's Best brands. JB Industries announced a 7.5% increase on brass access valves, capillary tubing, and fittings, along with a 10% increase specifically on vacuum pump oil. Johns Manville announced a 6% to 8% increase. Jones Stephens announced a 3% to 10% increase on select PEX products. Modine and Modine Unit Heaters announced a 0% to 9% increase varying by product category. Tutco announced a 10% increase. White-Rodgers Controls announced an unspecified increase.

Mid-July and Late-July Increases

Later in July: Advanced Distributor Products announced up to 3% on copper air handlers and up to 5% on copper evaporator coils, effective July 5. Aspen Manufacturing announced a 5% to 6% increase effective July 6. Fujitsu announced a 7% increase effective July 6 — the first Fujitsu pricing action in the current 2026 wave, adding the Japanese ductless equipment manufacturer to the list of major brands with active price adjustments in the U.S. market. Modular Metal Fabricators announced an 8% increase on all flex duct effective July 6. Nidec US Motors announced a 3% to 6.5% increase effective July 6. Quietflex Manufacturing announced a 6% to 8% increase effective July 6, having pushed back its original June 12 effective date to July.

Rectorseal announced up to 3% effective July 6. Supco announced an average increase of 3% to 5% effective July 6. Centrotherm announced a 7% increase effective July 12. Vybond announced a 6% increase on all HVACR products effective July 13. CertainTeed announced a 6% increase effective July 20.

Cumulative June-July Picture

The July round arrives on top of June's two-wave sequence. The June 1 wave included Airex (2% to 8%), Armacell (7% on all flexible elastomeric foam insulation), Design Polymerics (3.5% to 5%), Diversitech (1%), Emerson Nidec Motors (effective June 1 and June 27), Jones Stephens (10% on poly and rubber insulation), and Pro-Flex (up to 20% on some categories). The June second wave included Quietflex (6% to 8%, pushed to July), Taco Pumps, Filtration Manufacturing (3% to 7%), Mueller Streamline H&C Flex (8%), Owens Corning (6%), Parker Hannifin Filtration (TBD), AO Smith Water Heaters (7%), and Shurtape (2.5% to 7%).

For distributors managing inventory pricing and contractors quoting multi-week projects, the combined scope of June and July adjustments across insulation, flexible duct, filtration, motors, pumps, water heaters, valves, coils, venting, and tape means that a jobsite estimate prepared at the end of May against then-current pricing tables may now be materially incorrect across several line items. HARDI has advised distributor members to apply current pricing tables — not prior-month invoices — for all project quotes with July or later installation dates.

Tariff Relief Has Not Offset Ongoing Material Cost Pressures

The Trump administration's Section 232 tariff reduction for residential HVAC systems and components to 15% effective June 8 provided structural relief on the equipment side, but the accessories, insulation, duct, and component categories covered by the July price increase wave have their own tariff exposure through copper, aluminum, steel, and polymer input costs that are not always captured in the same derivative product categories as the residential equipment adjustment. For the July increases specifically, manufacturers citing tariff-related input costs as a driver for their adjustments noted that equipment-level tariff relief does not automatically reduce cost pressure on the accessory and component product lines that feed into the same installation work.
