Every contractor asks the same question when they’re short-staffed: is it worth paying a staffing agency, or should I just post the job and handle it myself? It’s a fair question. The agency fee is visible and immediate. The DIY costs are spread out, harder to track, and easy to undercount.
Here’s the real math.
The True Cost of DIY HVAC Hiring
Most contractors calculate DIY hiring cost as: job board post ($400) + 15 hours of their own time. That’s underestimating by a factor of four.
Direct costs:
- Job board posting (Indeed, ZipRecruiter): $400–$800 per posting
- Background check and drug screen: $80–$150 per candidate
- Skills assessment or trade test administration: $100–$200 if you use a service
Time costs (at your billable rate):
- Writing and managing the posting: 3–5 hours
- Screening resumes and applications: 5–15 hours depending on volume
- Phone screens: 1–2 hours per candidate, typically 8–12 candidates
- In-person interviews: 2–4 hours total
- Reference checks: 30–45 minutes per finalist
- Offer negotiation and paperwork: 2–4 hours
At $75/hour (a conservative owner/manager rate), that’s $1,500–$2,500 in time before a single person starts.
Then add the failure scenarios:
- A bad hire who washes out at 60 days means you restart the whole process
- A vacancy that runs 3–4 weeks while you’re hiring means delayed project delivery or overtime costs for your current crew
For a journeyman HVAC tech at $60,000/year, a 3-week vacancy can cost $3,000–$8,000 in overtime, missed bids, or subcontractor markups.
The Real Cost of an HVAC Staffing Agency
A typical placement fee is 18–25% of first-year base salary. For a journeyman HVAC tech at $60,000, that’s $10,800–$15,000.
That fee typically covers:
- Candidate sourcing and outreach
- Resume screening and application management
- Trade-specific technical screening
- Credential and license verification
- Background check and drug screening
- Reference calls
- Interview coordination
- Offer negotiation support
- Replacement guarantee if the hire doesn’t work out (90 days at reputable firms)
Time-to-fill: a good trades staffing firm delivers interview-ready candidates in 24–48 hours, versus 3–6 weeks for DIY.
The Break-Even Analysis
| Cost Factor | DIY | Staffing Agency |
|---|---|---|
| Direct recruiting costs | $600–$1,200 | $0 (included) |
| Your time cost | $1,500–$2,500 | ~$200 (interviews only) |
| Vacancy cost (3 weeks) | $3,000–$8,000 | $0–$500 (filled in 48hr) |
| Bad hire replacement | $5,000–$10,000 risk | Replacement guarantee |
| Total realistic range | $5,100–$21,700 | $10,800–$15,000 |
The DIY path looks cheaper at the top of the range. At the realistic average — factoring in vacancy time and one bad hire every 3–4 placements — the agency is cheaper or equal, and delivers in a fraction of the time.
When DIY Makes Sense
There are situations where handling hiring yourself is the right call:
- You have a deep referral network in your local trade community and placements consistently come from word of mouth
- Your hiring timeline is 4+ weeks and you can absorb a slow search without project impact
- You’re hiring for a role you’ve filled before with a clear candidate profile and no urgency
When a Staffing Agency Pays for Itself
- You need someone in the next 2–3 weeks
- Your last hire didn’t work out and you’re replacing a key position
- You’re entering a new market or trade type and don’t have local candidate networks
- You’ve tried posting twice and haven’t found the right person
