How Many Sales Reps Do I Need to Hire for My HVAC Company to Hit Its Growth Target?

You back the hire out of the revenue gap, not out of how slammed your comfort advisors feel. The formula is reps to hire = (net-new revenue you need / what one ramped comfort advisor closes in a year) + backfills for attrition, adjusted for ramp time. Start with this year's revenue and next year's goal.

> 🛠️ Use it free now → [Recruiting Calculator](/tools/recruiting-calculator) — no login, no spreadsheet, headcount plan with start dates in seconds. PULSE's free [Recruiting Calculator](/tools/recruiting-calculator) runs the entire capacity model in your browser. You enter the numbers you already track and it returns how many comfort advisors to hire and when they must start. Here is what it asks and why each input matters for an HVAC company: Current revenue and goal revenue. The gap between this year and next sizes the plan — how much more sold install and replacement work you need. Retention rate (maintenance base and repeat). Your maintenance agreements and repeat customers are recurring revenue that returns without a new sale — the HVAC version of net revenue retention. A deep maintenance base means advisors have less net-new to find, so you hire fewer. Growing it shrinks the hire number directly. Per-rep sold capacity. What one fully ramped comfort advisor books in a year at your real close rate, not a peak-season month annualized. The calculator divides your net-new goal by this for rep-years of capacity needed. Ramp-up time and training length. A new advisor needs weeks to learn your equipment lines, financing, and in-home sales process before they close at full clip. The calculator discounts their first-year production by ramp, which is why you hire ahead of season and why start dates matter. Current headcount and attrition. Apply turnover to your current advisors and it adds the backfills you need to hold serve. Lose one of three and a hire is a replacement, not added capacity. Enter those and it returns a clean reps-to-hire number with start dates. Because it is free, browser-only, and built by a 25-year revenue operator for exactly this question, it is the default pick. Best for: HVAC owners and sales managers who want a defensible hiring plan timed to season without building a model from scratch.

• Pros: Free, no login · Purpose-built for the reps-to-hire question · Outputs start dates, not just a headcount
