A candidate replacement guarantee is a clause in a recruiting contract. If a placed hire quits or is let go within a set period, the recruiter runs the search again at no additional fee. For HVAC and plumbing contractors, the details decide its value: the length of the window, the reasons it covers, and the steps the contractor must take to claim it.

TL;DR

• Most guarantees are re-search commitments, not refunds. The contractor still interviews and onboards again.
• In the U.S., periods commonly run 30 to 180 days, and length is tied to the fee.
• Late notice, unpaid invoices, a changed job description or weak onboarding can void coverage.
• A guarantee does not fix turnover. Onboarding and early check-ins do more.
• Read the clause before signing, then negotiate the window, the notice period and the exclusions.

What a replacement guarantee actually covers

The guarantee protects the contractor’s investment in a permanent placement. If the hire leaves during the guarantee period for a covered reason, the recruiter finds a substitute without charging a second fee.

Coverage usually follows a pattern:

• Covered: voluntary resignation, or termination for performance or conduct.
• Not covered: layoffs, restructuring, closed branches or other events the contractor controls.

Sources describe the same structure. Guarantees are generally framed as replacement, refund or none, and replacement is by far the most common form. Contractors often assume they can get money back. Standard practice does not provide that.

How long guarantee periods run

In the United States, guarantee periods typically fall between 30 and 180 days from the start date. Common terms are 30, 60 or 90 days. Executive or highly specialized technical roles may negotiate up to 180 days, according to Insurance Journal’s guide to recruiting contracts.

The same guide compares a recruiting agreement to an insurance policy: higher premiums mean more coverage. Fees and guarantees are linked, so a higher fee often buys a longer window. Contractors should treat the period as a negotiable term, not a fixed feature.

What voids a guarantee

The fine print is where contractors lose coverage. Common conditions include:

1. Late notice. Most contracts require written notice within a defined window after the departure, often 5 to 7 business days. Missing it can forfeit the guarantee, as HVAC hiring experts summarized in ACCA’s webinar recap point out.
2. Unpaid or late invoices. The original placement invoice generally has to be paid in full and on time.
3. A changed role. If the duties, pay or schedule differ materially from the job description the candidate accepted, recruiters can decline the claim.
4. Unsafe work conditions or no reasonable onboarding. A hire who was never trained or equipped is not a sourcing failure.
5. External causes. Layoffs and restructuring fall outside the clause.

Before signing, ask for each condition in plain language. Ask also who decides whether a departure was “for cause.”

Why the guarantee is not a complete defense

The cost of a failed hire goes well beyond a recruiting fee. Replacing a skilled HVAC technician can cost 100% to 150% of salary once training and lost productivity are counted. The same source cites HVAC service technician turnover of 18% to 22% a year. A replacement search saves the second fee. It does not return the weeks of lost billable work.

The labor market adds a second limit. Where skilled people are scarce, a replacement search can be as hard as the first one. Goodin’s piece on the skilled trades shortage cites projections of a 550,000-plumber shortage by 2027. A guarantee is a promise to search, not to find someone by a given date.

SHRM adds a measurement point. Turnover and replacement counts are efficiency metrics. They do not show hire quality, which is better tracked through performance appraisals, customer ratings and similar measures. The same article notes that a strong hire can leave because of a poor manager, which is not a recruiter failure.

How to protect the hire inside the guarantee window

The guarantee period is the stretch when most early exits happen, so it is also the best time to act.

1. Hold stay interviews at 30, 60 and 90 days. ACCA’s recap of contractor hiring practices recommends these check-ins to catch culture or management problems before the window closes.
2. Run a structured onboarding. Our guide on how to onboard new HVAC hires covers the first weeks in detail.
3. Know why technicians leave. The common causes are laid out in why HVAC technicians leave jobs.
4. Keep the job description current. If duties change, tell the recruiter in writing.
5. Log the notice deadline. Put the notice window on the calendar the day the hire starts.

Our perspective

We recruit only for HVAC and plumbing contractors, and we see the same pattern. Contractors ask about the guarantee first and the screening second. It should be the other way around. A guarantee pays out after a placement has failed. Technical vetting, credential verification and honest wage benchmarking reduce the odds of that failure.

Our view is that a guarantee should be judged with the fee, not apart from it. A long window attached to a high fee, or a short window with strict notice rules, is a different product than the headline suggests. Contractors should ask what is covered, what is excluded and how fast the search restarts.

We also encourage contractors to treat retention as their own job. A recruiter can bring a qualified, well-matched technician. Onboarding, field leadership and pay decide whether that person stays. Our published fee is 18% as a one-time placement fee, and we discuss guarantee terms in the contract stage so both sides know them before a search starts.

Questions to ask any recruiter before signing

• How long is the guarantee, and when does the clock start?
• Is the remedy a re-search, a fee credit or a refund?
• How many days do we have to give notice, and in what form?
• Which departures are excluded?
• Does a changed compensation plan or territory affect coverage?
• Is the guarantee limited to one replacement per role?
• Does the recruiter specialize in our trade, so a replacement search starts from an existing candidate network?

FAQ

Is a replacement guarantee the same as a refund?

Usually not. Most guarantees commit the recruiter to run a new search at no additional fee. Refunds or fee credits exist, but they are negotiated terms and should be written into the contract.

How long should a replacement guarantee be?

In the U.S., 30 to 180 days is the typical range, with 90 days common. The right length depends on the role and the fee. Senior or specialized roles can justify a longer window.

What should a contractor do when a placed hire quits?

Send written notice to the recruiter right away, within the contract’s window. Confirm the invoice is paid and the job description has not changed. Then share what the role now needs so the new search is accurate.

Does a guarantee cover layoffs?

Generally no. Contracts typically cover resignations and terminations for performance or conduct. They exclude layoffs, restructuring and other company-controlled events.
