Recommended exam prep
Formal prep pays for itself against a $100+ retake. Many states examine contractors on two separate papers — the trade exam and a business and law exam — so we list the course covering both first, with trade-specific depth after.

Form the business and get an EIN.
The Department of Safety and Professional Services issues the HVAC Qualifier / HVAC Contractor; the business that invoices Wisconsin 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.
Carry general liability insurance.
Wisconsin does not set a general liability minimum for this trade, but most permits and commercial customers ask for proof of GL cover. Workers' compensation is required once you hire employees. 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.
