Form the business and get an EIN.
The Mississippi State Board of Contractors issues the Mechanical Contractor (Commercial Major / Specialty / Residential); the business that invoices Mississippi 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.
Mississippi does not require a surety bond for this license — No statewide surety bond required by MSBOC. Local municipalities may require bonds.
Carry the insurance the license requires.
Mississippi requires general liability insurance for this license. General liability: minimum $300,000 per occurrence and $600,000 aggregate. Workers compensation: required if 5 or more employees. Contractor insurance requirements→
Register locally.
Many Mississippi municipalities require a separate local HVAC license or permit in addition to the MSBOC contractor license. Check with your local building department.
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.
