Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Air conditioning rose 5.7% over the last 12 months, but all of its main inputs rose faster: cold rolled steel sheet and strip +36.9%, copper and brass mill shapes +30.0%. That cost pressure may still pass through to prices.

A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Air-Conditioning and Warm Air Heating Equipment Manufacturing (BLS series PCU333415333415), published by BLS. Base Period: the index value published for September 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
Covers the cooling-equipment share of a data-center build, alongside the transformer and switchgear series.
Split the contract by what is being built: towers, fiber, data centers, or core network equipment. Towers, fiber and data centers have no single official price index for the finished project, so use a weighted composite of real cost inputs. Data centers have the best coverage: transformers (PCU335311335311) and switchgear (PCU335313335313) both have real, live BLS indices.
Escalake tracks US PPI — Air-Conditioning and Warm Air Heating Equipment Manufacturing, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
