Ask a home services CEO what their most important KPI is and you'll usually hear revenue growth or gross margin. Ask them their technician turnover rate and about half don't know it off the top of their head. That is the number that should be memorized.
In residential HVAC, plumbing, and electrical, a tenured technician generates 30–50% more revenue per hour than a first-year tech. They close more calls, they upsell more accurately, they get fewer callbacks, and — critically — they generate customer referrals that a rotating door of new hires simply cannot.
Turnover is also the largest hidden cost line in the business. Between recruiting, uniforms and vehicle setup, licensing, and the productivity ramp of a new hire, replacing a technician costs $15,000–$40,000 depending on the trade. In a 40-tech shop with 35% annual turnover, that's north of half a million dollars per year invisible in a standard P&L — often the difference between hitting plan and missing it.
The businesses we underwrite most aggressively share a pattern: sub-15% annual technician turnover, average tenure north of five years, and a defined career ladder from apprentice to lead. Those are the compounding assets. Where we see them, we pay up. Where we don't, we discount — or we pass.
The good news for founders: technician retention is one of the few operating levers that responds quickly. A defined career path, a real training program, transparent commission structures, and a manager who treats techs like professionals typically cut turnover in half within twelve months. It doesn't take capital. It takes will.
