Starting a mechanical contracting business is one of the most powerful long-term career moves for experienced steamfitters, HVAC technicians, and mechanical professionals. Many skilled tradespeople eventually reach a point where they want to move beyond working for someone else and begin building their own company.
In Pennsylvania, particularly in the Pittsburgh region, mechanical contracting businesses continue to grow due to infrastructure upgrades, industrial expansion, healthcare facilities, universities, and energy modernization projects.
This guide explains how to start a mechanical contracting business, what licenses and insurance are required in Pennsylvania, typical startup costs, and how union training can provide a long-term advantage.
What Is a Mechanical Contracting Business?
A mechanical contracting business typically installs, services, and maintains:

Before starting a business, strong technical experience is essential.
Most successful mechanical contractors begin as:
