What to do about it: Call the building department in each county where you set outdoor units and ask in writing whether 210.8(F) is enforced, including on permits already open. Add a line to proposals and work orders saying GFCI protection is required where the code is enforced and that nuisance-trip callbacks on a protected unit are billable. Ask your distributor which UL 943C high-frequency GFCIs each equipment maker approves for each model before you stock any, and file the answer with the job. Confirm your electrician or subcontractor is pulling the permit, tell customers in writing before install, and re-check once the Standards Council rules.

The index climbed from 359.5 in April to 375.9 in August, about 4.6% in four months, with no down month. It measures what materials cost to buy, not what you bid. If proposals written in the spring have not moved with it, the difference comes out of margin. Ask suppliers which index their surcharges follow. Source: FRED / BLS: PPI construction materials index

Why it matters: Since January 1, 2026, newly installed residential and nonresidential air conditioning in Washington must use refrigerant below 750 GWP, which rules out R-410A. EPA's revised technology transitions rule lets eligible pre-2025 R-410A equipment be installed until stock runs out, but state officials said on September 25 they are not currently planning to align. R-410A inventory you can place in most states you cannot place there. Washington also runs a refrigerant management program: systems with 50 pounds or more in a single circuit and refrigerant at 150 GWP or above must repair leaks within 14 days of discovery, with extensions to 45 or 120 days, and keep records five years.

Why it matters: ACHR reported on September 18 that Carrier lifted its read on the residential market to roughly 7.5 million units against an earlier 6.5 to 7 million, with 9.2 million as the 2024 baseline, and that it picked up about 30 basis points of residential share. Commercial is the stronger book: global commercial HVAC orders rose more than 50% in the first half, total backlog is a record $8 billion, and data center revenue is tracking near $2 billion this year and at least $3 billion next. Trane has already taken two residential increases of up to 5%, effective April 1 and July 1. Residential volume is recovering off a low base, so price is carrying revenue, not units.

Why it matters: The unanimous vote makes Appendix M of the Uniform Plumbing Code usable statewide as an alternative to the fixture-unit sizing tables in Chapter 6 of Colorado's adopted plumbing code, and Contractor counts Colorado as the twelfth state to allow it, after California, Hawaii, Montana, Nevada, New Jersey, New Mexico, North Dakota, Oklahoma, Oregon, Washington and Wisconsin. The method models peak demand statistically from modern fixtures instead of decades-old assumptions, which generally sizes mains and risers smaller. Smaller diameters cut copper and PEX takeoff, fitting counts, labor hours and hot-water stagnation. It is voluntary, so run it on your next multifamily bid before a competitor does.

Why it matters: USTR's final notice added 10% on imports from 17 economies that have forced-labor import bans or commitments, including Canada, Mexico, India, Indonesia, Malaysia and the UK, and 12.5% on the rest, including China, Vietnam, Thailand, Brazil and Turkiye, effective 12:01 a.m. on July 24, 2026. Articles already subject to Section 232 metal duties are exempt, as are raw materials and goods without adequate domestic supply. Contractor's August 7 read puts fixtures, valves, fittings, pumps, controls and motors in scope. Price this at the part number, not the category: ask each supplier which SKUs carry the new duty and which fall under the Section 232 carve-out before you re-quote.

Five of the seven lines land between 4.3% and 6%, so one blended assumption will underprice the outliers. Jones Stephens spans 5% to 15% by product group, and NTI put 30% on oil and wood heating products from September 3. Reprice from each manufacturer's own letter, group by group, not from a house average. Source: Supply House Times: PHCP-PVF Price Increases: September 2026

Why it matters: The Bureau of Industry and Security notice would extend Section 232 metal duties to 14 more derivative categories, among them electric conductor cables under HTSUS 8544.49.2000, 8544.49.3040, 8544.49.3080 and 8544.60.4000 at 25%, heat exchange unit parts under 8419.90.3000 at 25%, and filled steel propane, oxygen and propylene containers at 50%. Comments were due 21 days after publication on August 6. The notice sets no effective date and says nothing about how implementation will be announced, so the duty can land with little warning. Get country of origin and HTSUS codes for every cable, cord set and flex you stock, and ask distributors in writing whether open quotes hold if these lines are added.

Why it matters: The awards run through the Grid Resilience and Innovation Partnerships program under a Speed to Power initiative called SPARK, with recipients adding $3.35 billion of cost share for $5.25 billion of work. Beyond 1,500 miles of reconductored or rebuilt transmission, grid-enhancing technologies are slated for nearly 21,000 miles. This is utility transmission and distribution work, not building work, but it draws large conductor, connectors, hardware and line crews from the same regional pools you bid against. Expect longer lead times on large-gauge conductor and tighter crew availability in the 26 award states, and lock wire pricing and subcontract labor for 2027 jobs now rather than at bid time.

Why it matters: The Federal Register notice of September 16 finalized subsidy rates of 82.03% for Solarspace Technology (Laos) and for all other producers and exporters, and 153.67% for Vietnam Sunergy on adverse facts available. Critical circumstances were affirmative for VSUN and all others, so suspension of liquidation reaches 90 days before the preliminary determination, to November 28, 2025; for Solarspace the finding was negative and suspension begins February 26, 2026. The ITC must vote on injury within 45 days, and a negative vote terminates the case and refunds deposits. If modules you bought after late November 2025 came through Laos, confirm this week who your purchase contract names as importer of record.

Why it matters: Judge Mary McElroy of the U.S. District Court for the District of Rhode Island held that the One Big Beautiful Bill Act, signed July 4, 2025, gave EPA no discretion to end already-obligated grants, writing that Congress's clear intent was that EPA continue to administer them. The $7 billion sits inside the $27 billion Greenhouse Gas Reduction Fund; the awards were obligated by the September 2024 deadline and are available for five years. Residential installers who bid into a state Solar for All program should call the state energy office or grantee now for a restart schedule, and should not book the revenue or hire against it until any appeal is resolved.

The current-conditions index read 65.8 in August, up from 63.0 in July, while the six-month outlook fell to 68.4 from 73.9. Respondents credit grid and data center orders and blame policy uncertainty for the softer forward view. Both readings sit above 50, so distributor order books should hold through the fourth quarter.

Why it matters: EPA's sector table, last updated August 28, puts three separate January 1, 2027 installation dates in front of refrigeration contractors: remote commercial ice machines and remote refrigerated food-processing equipment lose specific high-GWP refrigerants, data center cooling drops to a 700 GWP ceiling, and supermarket systems fall to 1,400 GWP. Industrial process refrigeration above minus 30 Celsius is already at 150 GWP for charges of 200 pounds or more and 300 GWP below that. The date attaches to installation, not manufacture, so equipment still crated on January 1 is stranded. Put a firm install date in writing on every ice machine and food-processing order you place this quarter.

Why it matters: Contracting Business set out on September 10 what A2L compliance actually costs to install. Equipment with duct connections must carry a refrigerant detection system that shuts the unit down or ventilates the space when it senses a leak; systems holding four pounds of refrigerant or less are exempt. Total charge, isolation valves, exhaust, and the type and location of the air handler all decide whether an installation passes, and the International Building Code and International Fire Code are still being amended to match. Price the detection system, its wiring and any ventilation interlock as separate line items, and confirm with the local inspector which code edition is in force before you quote an A2L job.

What to do about it: You don't need a security program. You need multi-factor authentication on email and your accounting login, and one rule everybody follows: nobody changes bank details on the strength of an email or a call — you ring the number you already had on file and confirm. That covers most of it, and costs nothing. The part it doesn't — how the systems are set up — is the day job of our parent company, CyberSainya.
