Register Your Business Entity (Day 1)
Before getting any license, choose your business structure and register it with your state.
- Sole Proprietor โ Simplest, no filing required. But all liability is personal.
- LLC โ Recommended for most. $50-$200 filing fee. Protects personal assets. File with your state's Secretary of State.
- S-Corp โ Better for high-income businesses (saves self-employment taxes). More complex to set up.
- EIN โ Get this free at IRS.gov after forming your entity. Takes 5 minutes.
Get Your Local Business License (Week 1)
Every city and county requires a business operating license. This is your legal permission to do business at a physical address.
- Go to your city or county clerk's website โ search "[your city] business license."
- Most are $25-$200 and can be filed online.
- If operating from home, also apply for a home occupation permit (required in most jurisdictions).
- Renew annually โ most expire December 31st.
Get State-Required Licenses (1-3 months)
Depending on your hvac business type, you may need state-issued professional licenses or certifications.
- Search "[your state] hvac business license" to find the specific state board.
- Some licenses require passing an exam โ allow 4-8 weeks of study time.
- Some require proof of insurance before the license is issued.
- Many states have a centralized business portal โ search "[your state] business one-stop."
Get Business Insurance
Insurance isn't a license, but it's often required before getting licensed and before clients will hire you.
- General Liability โ Covers third-party injuries and property damage. $300-$1,500/year.
- Professional Liability / E&O โ Covers claims of negligence or bad advice. Essential for consultants and professionals.
- Workers' Comp โ Required in most states if you have employees.
- Get quotes from Hiscox, Next Insurance, or State Farm's business insurance.
Open a Business Bank Account + Register for Sales Tax
The final compliance steps before taking your first paid client.
- Open a separate business checking account (Chase, Mercury, or Relay are popular choices).
- Register for sales tax in your state if you sell taxable products or services (free to register).
- Set up accounting software (QuickBooks, Wave, or FreshBooks) to track income and expenses from day one.
Contractor licensing is highly state-specific. California, Florida, and Texas have strict licensing requirements with exams. Some states (like Wyoming) require only a business license. Always verify with your state contractor board.
