Hardware, Plumbing & HVAC Distributors

The 9,400 hardware, plumbing, and HVAC/R distributors in the US consolidate a variety of products from many different manufacturers to offer customers wide selection, reasonable prices, and a single point of contact. Distributors may sell a combination of product categories or specialize.

Construction Drives Demand

Hardware, plumbing, and HVAC distributors depend on construction projects as major sources of revenue.

Consolidation Continues

Distributors continue to expand into new industries and geographical markets or gain market share via acquisitions.

Sep 23, 2026 - HVACR Distributor Sales Rise in July

• The Heating, Air-conditioning & & Refrigeration Distributors International (HARDI) reports member distributor sales increased 6.7% in July compared with July 2025, the strongest monthly gain of 2026 when adjusted for the same number of billing days. Higher sales can improve product movement for HVAC distributors, although HARDI cautioned that unusually hot weather helped drive the result, and underlying end-market demand remains subdued. Sales for the 12 months through July increased 2.7%. Days sales outstanding, a measure of how quickly customers pay their bills, were less than 37 days and roughly unchanged from a year earlier, which HARDI said suggests market conditions are not deteriorating. The association noted housing and consumer sentiment remain under pressure from inflation and said more durable improvement would be easier to identify if inflation and interest rates eased.
• Contractor confidence turned broadly negative in the third quarter, reversing the mostly positive picture from the second quarter, according to the Home Improvement Research Institute (HIRI). Mechanical contractor confidence declined during the quarter, which may signal softer near-term conditions for distributors serving HVAC and plumbing contractors. Housing affordability improved in every US region in July compared with a year earlier, according to the National Association of Realtors (NAR). The national Housing Affordability Index rose 5.1% year over year to 103.3 and increased 1.5% from June. The West posted the largest annual gain at 8.8%, followed by the South at 6.8%, the Midwest at 4.3%, and the Northeast at 4.1%. Improving affordability is an important housing-market indicator for hardware, plumbing, and HVAC distributors, as HIRI tracks housing conditions to assess their influence on home improvement demand.
• The American Supply Association reports renewed inflation in metals, freight, energy, and other inputs is increasing supply chain cost pressure. Rising supplier and logistics costs can complicate purchasing, inventory, pricing, and margin decisions for plumbing, HVAC, and hardware distributors, particularly when it is unclear which increases will persist. Producer prices for final demand rose 0.4% in August and 5.4% from a year earlier. Transportation and warehousing services increased 1.3% during the month, while building materials, paint, and hardware wholesaling rose 1.6%. The ASA says higher costs eventually may move downstream through prices, surcharges, or changes in purchasing strategies.
• Single-family housing starts jumped 7.6% in August from July to a seasonally adjusted annual rate of 918,000, while permits for future single-family construction fell 1.8% to 878,000, according to Reuters reporting of Census Bureau data. Single-family starts were 5.2% above their August 2025 level, but Reuters noted the permit decline suggested the monthly improvement in construction could prove temporary. Higher mortgage rates remain a headwind for housing activity. Increased starts can support near-term demand for plumbing, HVAC, hardware, and other building products supplied to homebuilders and contractors. However, weaker permitting points to a less certain pipeline for future residential construction and related product orders. Distributors may need to balance inventory and purchasing decisions against current demand while remaining cautious about stocking for a housing recovery that has yet to show sustained momentum.
