A prospecting guide for commercial mechanical contractors in the San Francisco-Oakland-Fremont, CA 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 San Francisco-Oakland metro has 3,660 larger buildings in HVAC-buying categories, led by medical and dental office buildings (1,089), and 286 nonresidential plumbing and HVAC contractors working them. Start in Alameda County, San Francisco County and Contra Costa County, where 79% of them sit.
These are the 10 industries Abstrakt's SDRs call for HVAC work, with how many of each are in the San Francisco-Oakland 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 hospital campuses 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: San Francisco and nearby markets
286 nonresidential plumbing and HVAC contractors are based in the San Francisco-Oakland metro. 7 more opened over the past year, so buyers are fielding new names. The trade is 50% less concentrated than the U.S. as a whole, so a consistent outbound program reaches facility teams that are not tired of contractor calls. 12.8 larger HVAC-buying buildings per contractor puts San Francisco 20 of 100 markets, and 5 of 11 in California. That is more room per contractor than most metros, so systematic prospecting tends to find accounts nobody is working. If you can serve Stockton and San Jose, they have more larger buildings per contractor than San Francisco.

Your outsourced sales development team works the numbers above under your name. Here is the plan for San Francisco commercial mechanical contractors.
Abstrakt's records already hold 5,014 eligible HVAC targets in the San Francisco-Oakland metro. Your ideal customer profile becomes a target list drawn from those records and the 3,660 larger HVAC-buying buildings in the metro, starting in Alameda County and San Francisco County. That is about 3.3 times the 1,500-account list a Foundation program starts with, so the list is ranked Tier 1 first and worked in waves.
For HVAC, that starts with the practice administrator or office manager at medical and dental office buildings, then two or three contacts at each of the 1,020 Tier 1 sites. Calls, email and LinkedIn run together; Growth adds direct mail and intent data.
Your SDR calls San Francisco facility teams every month of the year at the same pace. What changes is the message: each account's renewal month, and the problems the building is dealing with right now. The calendar never stops filling.
Every meeting passes Right Company, Right Contact and Right Timing, and arrives with the equipment notes, the incumbent and the renewal month.
The Results Portal shows every call, email, conversation and booked meeting in the San Francisco program, around the clock.
