CRD Jobs

What "CRD Jobs" Actually Means for a Legacy Credential

When people search for "CRD jobs," they usually want to know one thing: does holding this credential open doors in the ground source heat pump (GSHP) industry? The Certified Residential Geothermal Designer credential, issued by IGSHPA, signals that a person has been trained and examined in the design of residential geothermal systems. That is a narrow, practical skill set, and the jobs that value it are narrow and practical too.

There is an important framing point up front. According to IGSHPA's January 2026 white paper on sunsetting legacy training courses and certifications, normal legacy training was reported as replaced by the end of 2025. The CRD is therefore a legacy credential. That does not make it worthless to the people who hold it, and it does not mean it disappears from resumes overnight. It does change how you should think about it: as a credential that existing holders maintain, not one that new entrants can assume they will freely earn. If you are new to the acronym itself, our explainers on what CRD is and what CRD stands for cover the identity question in detail.

Who Hires Residential Geothermal Designers

The CRD is a design credential, so the employers that care most are the ones that put a pencil to a loop field before anyone digs. Typical hiring environments include:

• Geothermal and GSHP contractors. Companies that sell, design and install ground-loop and heat pump systems for homes need someone who can size equipment and loops rather than guess.
• HVAC contractors expanding into geothermal. Traditional heating and cooling firms adding ground source offerings often look for a designer on staff or a certified person to lead the first projects.
• Drilling and loop-installation firms. Businesses that install vertical or horizontal loops benefit from in-house design knowledge when coordinating with HVAC partners.
• Utility and incentive programs. The white paper's very framing, recommendations for utility, state and provincial programs, shows that these programs are where legacy credentials still carry weight. Some programs reference IGSHPA certification as a qualification for participating contractors.
• Engineering and energy consulting firms. Firms that evaluate residential energy options may value designers who understand ground-coupled systems and their economics.
• Trade associations and training organizations. Because the credential was historically delivered with partners such as HRAI in Canada, designers with the CRD may find work in training, technical support or program administration.

Notice what this list does not claim. We are not quoting openings, headcounts or salary bands, because none were verified for this credential. For a qualitative look at earning potential and how to weigh it, see our CRD salary guide and the broader analysis of whether the CRD is worth it.

What the Work Looks Like: Mapping Duties to the Nine Curriculum Topics

The clearest way to understand what a CRD-credentialed designer does is to look at what the preparation covered. The historical IGSHPA course listing organized the material under nine headings. These are preparation-topic headings, not weighted exam domains, and they do not define an exhaustive exam blueprint. Still, they map neatly onto real job tasks. For a deeper walk-through, see our guide to all nine CRD content areas.

Those nine topics tell a hiring manager exactly what a CRD holder was trained to do. If you are assessing how demanding they are, our piece on how hard the CRD exam is breaks down what makes the quantitative topics tougher than the conceptual ones.

Job Titles Where the CRD Shows Up

The credential rarely appears in a job title by itself. It usually shows up as a preferred or required qualification inside a broader role. The table below describes how the CRD tends to relate to common positions. It is qualitative and does not reflect any verified posting data.

Legacy Status: What Hiring Managers Need to Know

Because the CRD sits in a legacy category, employers and job seekers alike should understand three realities drawn from IGSHPA's published position.

1. Existing certifications remain valid when maintained. Active CRD holders may continue renewing indefinitely, with required continuing education, as long as the certification does not lapse.
2. Lapsed credentials cannot be reinstated. IGSHPA's current FAQ states this plainly. For a working designer, a missed renewal is not a paperwork inconvenience; it can permanently end the credential.
3. The GRSD exam is a separate, optional upgrade path. Taking it does not rename or automatically replace the CRD. Treat it as a different credential decision, with its own objectives, rules and costs that should not be assumed to mirror the CRD's.

Keeping the Credential Alive: Renewal Costs and CEUs

For anyone whose job depends on holding the CRD, renewal mechanics are the most practical part of the whole picture. IGSHPA's renewal policy, with its fee structure effective January 1, 2024, offers one-, two- or three-year terms.

A few details trip people up:

• These are renewal charges, not exam fees. No initial-exam fee for the legacy CRD was verified, so do not assume any figure you see elsewhere applies.
• CEU points are not classroom hours. IGSHPA describes eight CEU points per three-year cycle. Confusing points with hours could leave you short at renewal time.
• Membership must cover the discounted term. To get the member renewal price, your membership term has to span the renewal term you purchase.
• You may not need a separate membership. If you are covered by an eligible business, community or utility membership, an individual membership is unnecessary.

For the total picture of what holding the credential costs over time, see our CRD certification cost breakdown. The member-versus-non-member gap is large enough that, for most employed designers, membership pays for itself in the first renewal decision.

Existing Holders Versus New Candidates

The job-market picture differs sharply depending on which side of the credential you stand on.

If You Already Hold the CRD

Your priority is continuity. Track your renewal date, collect CEU documentation as you go, and decide early whether employer-covered membership applies to you. Your credential is a durable asset only if it never lapses. Update your resume to say "Certified Residential Geothermal Designer (IGSHPA), active" with the renewal status accurate.

If You Are Considering Earning It

Pause and verify. New-candidate availability is on verification hold until a specific current legacy offering from the issuer is confirmed, and legacy courses are offered case by case where a utility, state or provincial program requires them. Before investing time, ask whether a program in your region actually requires the CRD. Our overview of CRD requirements and eligibility and the current-status discussion in CRD training can help you frame the right questions. You can also read our note on exam dates and scheduling to understand why a calendar listing alone is not enough evidence of availability.

Positioning Your CRD on a Resume and in Interviews

Hiring managers in this niche tend to probe practical depth. A few ways to make the credential count:

• Lead with the function, not the acronym. Write the full name, Certified Residential Geothermal Designer, so no reader confuses it with another credential that shares the letters.
• Tie it to the design workflow. Describe a project where you ran load calculations, selected a heat pump type and specified loop piping, and say what the economics looked like for the homeowner.
• Mention site judgment. Interviewers love hearing how soil or geology changed a design decision.
• State your renewal status. A line noting the credential is active signals you manage your professional obligations.
• Be candid about its legacy status. Acknowledging that it is a legacy IGSHPA credential, and noting any interest in the GRSD upgrade path, shows industry awareness rather than naivety.

For a broader view of the credential's meaning and what employers read into it, the explainers on CRD certification and what CRD certification is offer useful background to share with colleagues.

A CRD-Specific Preparation Sequence

For anyone working through the historical material, whether to refresh knowledge or to prepare under a program-specific offering, sequence matters more than raw hours. The nine topics build on one another, so study them in dependency order. Our CRD study guide goes further; this is the condensed logic.

Load calculations come before pipe design on purpose: you cannot size piping responsibly without knowing the load it must serve. Because no current legacy-exam question count, time limit or passing mark was verified, rely on the issuer's current instructions rather than any figure you find elsewhere; our pages on the passing score and pass rate explain what is and is not known. A condensed CRD cheat sheet is helpful for last-minute review, and the main practice test site offers question practice to test your recall of these topics.
