Form the business and get an EIN.
The Ohio Construction Industry Licensing Board issues the HVAC Commercial Contractor; the business that invoices Ohio customers is a separate decision. A sole proprietorship is the default, an LLC keeps business liability off your personal assets, and either needs an EIN before the first payroll. Settle it before the license number goes on an estimate.
Bond: none required by the state.
Ohio does not require a surety bond for this license — The OCILB does not require a surety bond for HVAC contractor licenses at the state level. Local jurisdictions may impose bond requirements.
Carry the insurance the license requires.
Ohio requires general liability insurance for this license. Minimum $500,000 contractor liability insurance required, with OCILB listed as certificate holder. Workers' compensation required through Ohio BWC for all employers with employees (monopolistic state fund). Contractor insurance requirements→
Set up quoting, scheduling and invoicing before the first call.
Your first customers will ask for a written estimate and expect to pay by card on site. Most one-truck HVAC technician businesses run that on field-service software; Housecall Pro is the one we link because it is built for this size of company and this link carries 20% off your first 12 months.
