The trade is 35% less concentrated than the U.S. as a whole, so a consistent outbound program reaches facility teams that are not tired of contractor calls. 15.5 larger HVAC-buying buildings per contractor puts Seattle 6 of 100 markets, and 1 of 2 in Washington. That is more room per contractor than most metros, so systematic prospecting tends to find accounts nobody is working. Seattle has more larger buildings per contractor than the nearest markets.
