Need a HVAC Contract in Oklahoma? AroundWire Can Help

In Oklahoma, HVAC contracts—whether for installation, repair, or maintenance—are governed by a combination of state statutes, administrative rules, and local ordinances. Contractors must hold an active Mechanical Contractor license issued by the Oklahoma Construction Industries Board, and all technicians are required to have appropriate journeyman or apprentice certifications. Contracts typically mandate proof of general liability insurance (often with minimum coverage around $500,000) and workers’ compensation insurance for all employees. Prevailing wage laws generally do not apply except on certain public projects. Detailed scopes of work, clear timelines, and itemized pricing are standard, with payment terms commonly structured as progress payments tied to milestones or completion of work phases; retainage (typically 5-10%) may be withheld until final inspection and acceptance. State law requires prompt payment for undisputed invoices on public projects, usually within 30 days. Contractual risk factors include strict adherence to building and energy codes (notably the adopted International Mechanical Code and International Energy Conservation Code), and liability for non-compliance or defective work is a primary concern. Indemnification and hold harmless clauses are common. Dispute resolution often favors negotiation and mediation before litigation; some contracts may specify arbitration. Oklahoma statutes limit certain contract terms, such as “pay-if-paid” clauses, and require clear change order processes. Contractors should also be aware of municipal permitting requirements and possible bonding obligations for larger public jobs.
