When Should You Use Retained Recruitment in HVAC Hiring?

​Most businesses default to contingency recruitment.

No upfront cost, multiple agencies, quick CVs — on paper it looks like the safest option.

But in HVAC, where candidate shortages are real and the best people aren’t actively applying for jobs, this approach often creates more problems than it solves.

The reality is this:

If a role really matters, contingency recruitment is usually the wrong approach.

Here’s when retained recruitment becomes the better option — and why more HVAC employers are shifting towards it.

​

YOU SHOULD USE RETAINED RECRUITMENT WHEN THE ROLE ACTUALLY MATTERS

This sounds obvious, but it’s where most hiring strategies fall down.

If the role:

• Impacts operations

• Affects service delivery

• Influences client relationships

• Is difficult to replace

Then it’s not a “see what happens” hire.

Contingency works when: “If we fill it, great”

Retained works when: “We need to fill this properly”

​

WHEN YOU'VE ALREADY TRIED (AND FAILED) TO FILL THE ROLE

One of the clearest signals you need to switch approach:

• The role has been live for weeks (or months)

• Multiple agencies have sent CVs

• Interviews haven’t led to hires

• Candidates are dropping out

At this point, the issue usually isn’t the market — it’s the method.

Contingency recruitment becomes repetitive retained recruitment becomes targeted

​

WHEN THE BEST CANDIDATES AREN'T APPLYING

In HVAC, the strongest candidates are rarely active job seekers.

They’re:

• Already employed

• Selective about opportunities

• Open to the right move — but not browsing job boards

Contingency recruitment relies heavily on:

• Job adverts

• Existing applicant pools

Retained recruitment focuses on:

• Direct headhunting

• Targeted outreach

• Engaging passive candidates

If you want access to the top 20% of the market, you need a retained approach

​

WHEN SPEED IS IMPORTANT - BUT FAILURE IS NOT AN OPTION

There’s a misconception that contingency is faster.

It often delivers CVs quickly — but not always results.

Retained recruitment may take a more structured approach, but it typically delivers:

• Stronger shortlists

• Higher candidate commitment

• Fewer dropouts

• Better long-term hires

Faster isn’t always better if it leads to repeat hiring

​

WHEN YOU NEED MARKET INSIGHT - NOT JUST CV'S

A strong retained search should give you:

• Honest feedback on salary levels

• Insight into candidate availability

• Advice on role positioning

• Guidance on interview process

If your recruiter is just sending CVs without challenging your brief:

You’re not getting value — regardless of the fee

​

WHEN THE COST OF A BAD HIRE IS HIGH

This is the part most businesses underestimate.

A bad hire in HVAC can lead to:

• Project delays

• Contract risk

• Increased workload for existing teams

• Additional recruitment costs

Suddenly, saving a few percent on fees doesn’t matter.

The focus shifts from cost to outcome

​

WHY MORE HVAC EMPLOYERS ARE MOVING TOWARDS RETAINED RECRUITMENT

The market has changed:

• Candidate shortages are increasing

• Skilled engineers and managers are harder to attract

• Competition between employers is higher

As a result:

The “post and pray” model doesn’t work anymore. Reactive recruitment is being replaced by proactive search

Retained recruitment aligns with this shift.

​

COMMON MISCONCEPTION: "RETAINED IS MORE EXPENSIVE"

In reality:

• The overall fee is often similar

• The structure is different (staged payments)

• The delivery is significantly stronger

The real difference isn’t cost — it’s:

Level of commitment and quality of outcome

THE REAL QUESTION: HOW IMPORTANT IS THE HIRE?

This is what it comes down to.

If the role is:

• Critical

• Hard to fill

• Business-impacting

Then retained recruitment isn’t a luxury — it’s the right approach.

If it’s not:

Contingency may still be the better fit.
