A prospecting guide for commercial mechanical contractors in the St. Louis, MO-IL metro: which buildings to target, where they are, who signs, and how Abstrakt books the meetings.
Ask Ava anything about the information on this page.
The St. Louis metro has 2,405 larger buildings in HVAC-buying categories, led by manufacturing plants (814), and 225 nonresidential plumbing and HVAC contractors working them. Start in St. Louis County, St. Louis city and St. Charles County, where 82% of them sit.
These are the 10 industries Abstrakt's SDRs call for HVAC work, with how many of each are in the St. Louis metro and who to ask for. No HVAC-buying category is markedly over-represented here, so the list should follow size and fit rather than one dominant industry. Colleges and universities and hosting and data processing companies are thinner than the national mix, so treat them as selective targets.
Locations are establishments with 20 or more employees (U.S. Census Bureau, County Business Patterns 2023); property management and similar companies are counted in full, whatever their size. Change and concentration: U.S. Bureau of Labor Statistics, Quarterly Census of Employment and Wages, private ownership, 2026 Q1.
Buildings per contractor: St. Louis and nearby markets
225 nonresidential plumbing and HVAC contractors are based in the St. Louis metro. That is 1 fewer than a year ago. When a contractor closes or sells, its customers go looking for a new one. The trade is at about the national concentration. 10.7 larger HVAC-buying buildings per contractor puts St. Louis 38 of 100 markets, and 1 of 2 in Missouri. That sits mid-pack: real room to grow, but the best accounts are contested. If you can serve Indianapolis and Louisville, they have more larger buildings per contractor than St. Louis.
