Form the business and get an EIN.
The Iowa Plumbing and Mechanical Systems Board issues the Journeyperson / Master HVAC-Refrigeration; the business that invoices Iowa 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.
Post the bond.
Iowa requires a $5,000 surety bond. HVAC contractors must obtain a $5,000 surety bond. Master contractors must also maintain $500,000 liability insurance. How contractor bonds work→
Carry the insurance the license requires.
Iowa requires general liability insurance for this license. HVAC contractors must maintain $500,000 general liability insurance and workers comp (if employees). Must maintain a permanent place of business. Contractor insurance requirements→
Set up quoting, scheduling and invoicing before the first call.
