Register your LLC or corporation with the New York Secretary of State. This is your first step even though New York does not require a state-level hvac contractor.
Apply for a federal Employer Identification Number (EIN) from the IRS. This is free and can be done online at irs.gov.
Since New York does not have a state-level license, check with your local city or county for registration requirements. Many cities in New York require local contractor registration or permits.
Obtain general liability insurance ($500K-$1M minimum recommended). While New York may not require it by law, most clients and project owners will require proof of insurance before hiring you.
If you have or plan to hire employees, workers' compensation insurance is required in New York. Even as a sole proprietor, consider it for personal protection.
Register for New York sales tax and any local business taxes. Set up your business bank account and accounting system.
Without a state license requirement, your reputation is everything. Consider voluntary certifications, join local trade associations, collect reviews, and maintain a professional online presence.
