617 nonresidential plumbing and HVAC contractors are based in the Houston-Pasadena metro. 10 more opened over the past year, so buyers are fielding new names. The trade is 43% more concentrated than the U.S. as a whole. Facility teams here already hear from commercial mechanical contractors, and a specific reason to talk beats a generic pitch. 8.1 larger HVAC-buying buildings per contractor puts Houston 75 of 100 markets, and 2 of 6 in Texas. That is toward the crowded end, so growth here comes mostly from displacing incumbents at renewal. If you can serve Dallas, it has more larger buildings per contractor than Houston.

Tier 1 covers manufacturing plants, medical and dental office buildings and senior living and skilled nursing with 50 or more people on site.
