Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings The Company is involved in various claims and legal proceedings incidental to its normal business activities. When a potential loss from a proceeding or claim is considered probable and the amount can be reasonably estimated or a range of loss can be determined, a loss contingency is recorded. The Company also provides disclosure when it is reasonably possible that a material loss will be incurred. Although the outcome of such claims and proceedings cannot be predicted with certainty, the Company vigorously defends its position in all such matters. The Company is not aware of any known contingencies, claims or lawsuits that will have a material effect on its financial position, results of operations or cash flows other than those described herein. Insurance The Company carries various insurance policies to address identified risks of loss including cyber, general liability, worker’s compensation, automobile liability and professional liability risks. As of March 31, 2026 and December 31, 2025, a liability for known and expected but not yet reported claims of $2.9 million and $2.6 million, respectively, was reflected in Accrued and other current liabilities on the Condensed Consolidated Balance Sheets. The determination of such claims and expenses and the appropriateness of the related liability is continually reviewed and updated by management. The Company is self-insured for its medical coverage. The Company is responsible for the first $0.3 million of claims for each participant enrolled in the medical coverage plan. Any claims exceeding $0.3 million are covered through a stop-loss insurance plan. A liability for expected but not yet reported claims in the amount of $2.8 million and $3.2 million was reflected in Accrued compensation and benefits on the Condensed Consolidated Balance Sheets as of March 31, 2026 and December 31, 2025, respectively. Surety As a requirement under certain contracts, various Legence subsidiaries procure performance and payment bonds through surety underwriters. As a condition for having surety companies write bonds on Legence subsidiaries’ behalf, Legence enters into indemnification agreements with the surety companies. Total outstanding bonds were approximately $1,562.4 million and $561.5 million as of March 31, 2026, and December 31, 2025, respectively. Customer Guarantees As part of its normal course of business, the Company offers guaranteed energy savings to customers under certain contracts. As of March 31, 2026 and December 31, 2025, total guarantees were $299.8 million and $307.4 million, respectively. Historically, the Company has not incurred material losses in connection with these guarantees. Further, management is not aware of any changes in the ability of the Company to meet these guarantees and does not expect to incur significant losses related to these guarantees in the foreseeable future.

As of March 31, 2026 and December 31, 2025, the Company had $30.7 million and $5.7 million, respectively, in standby letters of credit primarily related to surety bonds and the deductibles of insurance policies.
