The trade is 41% less concentrated than the U.S. as a whole, so a consistent outbound program reaches facility teams that are not tired of contractor calls. 13.3 larger HVAC-buying buildings per contractor puts San Diego 14 of 100 markets, and 3 of 11 in California. That is more room per contractor than most metros, so systematic prospecting tends to find accounts nobody is working.
