More than a dozen HVACR manufacturers announced or implemented price increases effective June 1 or later in June 2026, adding another layer of cost pressure on distributors and contractors already absorbing tariff-related surcharges, A2L equipment transition costs, and rising refrigerant prices.
The June round of price increases was reported by ACHR News and covers a range of product categories that fall outside the major equipment lines — insulation, valves, duct sealants, motors, pumps, water heaters, filtration products, flexible duct, tape, and controls — segments where pricing action is often a leading indicator for broader equipment cost movement, since these materials feed directly into contractor job costs and distributor inventory expense lines.
The June 2026 Price Increase List
Among the manufacturers announcing adjustments for June 2026: Airex announced an increase of 2% to 8% on applicable products effective June 1. Armacell, the elastomeric foam insulation manufacturer, announced a 7% increase on all flexible elastomeric foam insulation products effective June 1. Design Polymerics, a duct sealants and coatings supplier, announced a 3.5% increase on select duct sealants, specialty coatings, and adhesives, along with a 5% increase on its DP 1090 product, effective June 1. DiversiTech implemented a 1% increase effective June 1. Emerson Nidec Motors implemented a general price increase effective June 1, with a second round taking effect June 27. Jones Stephens announced a 10% increase on poly and rubber insulation effective June 1. Pro-Flex announced a set of adjustments with varied rates by product category, including 6% on CSST and fittings, approximately 8% on MDPE gas pipe, and 5% on rigid anodeless risers, with some categories seeing decreases.
The Context: A Year of Compounding Costs
The June increases arrive on top of a first-quarter 2026 round of price actions that itself came on top of a wave of increases in late 2025 and early 2026. For distributors managing inventory and contractors quoting multi-week or multi-month projects, the frequency and breadth of adjustments across both equipment and accessory categories makes maintaining accurate cost-in pricing a continuous operational challenge. The June 2026 round is particularly notable for its concentration in insulation and flexible duct products — materials used in virtually every residential and light commercial HVAC installation — meaning the increases flow directly into the cost of routine work rather than only affecting specialized applications.
The broader tariff environment driving many of these adjustments remained in flux through late June 2026. The Trump administration's Section 232 proclamation reducing tariffs on residential HVAC systems and components from 25% to 15%, effective June 8, provided some relief on the equipment side, but accessories, insulation, and piping products face their own tariff exposures through steel, aluminum, copper, and polymer input costs that are not always captured in the same derivative product categories that the HVAC equipment adjustment covered.
What the Construction Cost Data Shows
The price increases are taking place against a backdrop of sustained construction input cost inflation. An Associated Builders and Contractors analysis of April 2026 Bureau of Labor Statistics Producer Price Index data found that construction input prices increased 1.7% in April versus March, and 6.2% over the first four months of 2026 — more than the 4.8% increase recorded across the entirety of the prior three years. ABC chief economist Anirban Basu said much of the April increase is traceable to soaring oil prices, with tariff-affected materials including iron and steel posting particularly large monthly gains. For HVAC contractors whose accessory and material purchasing is tracked against monthly supplier price lists rather than locked-in annual contracts, that input cost acceleration feeds directly into project margins on existing quoted work that cannot be repriced before completion.
HARDI has advised distributor members to monitor each manufacturer's effective dates carefully and to track price adjustments by product category, since staggered effective dates mean that a jobsite estimate prepared in late May against then-current pricing may be materially wrong if accessory orders are placed in late June after new rates have taken effect. Contractors building multi-week or multi-month project quotes should consider whether their contract terms include material escalation provisions that would allow repricing if supplier costs increase after a bid is submitted, as the frequency of mid-year price adjustments in 2026 has made fixed-bid project structures with no adjustment mechanism a source of meaningful margin compression risk.
