GA-CAC Salary Guide 2026: Complete Earnings Analysis

TL;DR
  • The Class II license is "unrestricted," meaning no BTU ceiling limits the commercial work you can bid.
  • System Design carries 55% of the exam weight - the domain most tied to design-build billing rates.
  • Five years of required experience, including commercial work above 175,000 BTU heating/60,000 BTU cooling, already builds your resume before you're licensed.
  • The $110 application fee is a small fraction of the long-term value an unrestricted license adds to your career.

How the GA-CAC License Shapes Earning Potential

Georgia's Conditioned Air Contractor Class II (Unrestricted) license doesn't come with a published salary chart from the Georgia Construction Industry Licensing Board, and any site that tells you otherwise is likely borrowing numbers from an unrelated credential that happens to share the "GA-CAC" acronym. What the Board does publish is something arguably more useful for a serious tradesperson: the exact scope of work, experience thresholds, and technical domains that determine what kind of jobs you're legally allowed to sign your name to. Earning potential in this trade follows scope of work, and scope of work is exactly what this license controls.

This guide breaks down the earnings logic of the Class II license by connecting it to the concrete facts of the credential itself - the exam structure, the experience requirements, and the renewal obligations - rather than inventing numbers that don't exist in the Board's materials. If you want the full mechanics of the exam first, start with the overview of what GA-CAC certification actually is and the complete requirements breakdown.

Why This Matters: A Class II Unrestricted license removes the tonnage and BTU ceilings that limit lower-tier or restricted licenses. That single fact is the biggest earnings lever in this credential - it determines which contracts you can legally accept.

Why "Unrestricted" Matters for Your Paycheck

The word "Unrestricted" in the license name isn't marketing language - it's a legal scope designation from the Division of Conditioned Air Contractors. Contractors and technicians who hold restricted licenses are typically capped on system size or building type. The Class II Unrestricted credential removes those caps, which means license holders can pursue commercial installation, maintenance, and repair contracts on large systems without needing a second contractor to sign off on the bigger jobs.

In practical terms, that scope difference is what allows an unrestricted license holder to bid on hospital HVAC retrofits, large multi-tenant office buildings, or industrial conditioned-air systems - work that pays differently than single-family residential service calls precisely because of the complexity, liability, and equipment size involved. The exam itself reflects this: it requires reference-permitted, code-based competency across the 2024 Georgia Gas and Mechanical Codes with Georgia amendments and the 2023 NEC, not just basic residential troubleshooting.

Key Takeaway

Your earning ceiling is tied directly to license scope. An unrestricted Class II credential is what unlocks larger commercial contracts - the exam is simply the gatekeeping mechanism for that scope.

How Each Exam Domain Translates Into Billable Skill

The GA-CAC Class II exam is organized into four domains, and each one maps to a category of paid work in the field. Understanding this mapping helps explain why certain domains carry more exam weight - they also tend to carry more complexity, and complexity is what commercial clients pay for. For a full breakdown of each domain's content, see the complete guide to all four content areas.

Domain 2: System Design (55% - the largest domain)

This is both the heaviest domain on the exam and the skill set most closely tied to design-build and consultative work. Contractors who can perform accurate heat-loss/gain calculations and duct design using Manuals J, D, N, and Q are the ones capable of speccing entire systems - not just installing what someone else designed.

  • Load calculation accuracy directly affects change-order risk on commercial jobs
  • Duct design competency (Manual D) reduces callback and re-work costs
  • Design-capable contractors are positioned for larger commercial bids

Domain 1: Regulations, Laws, and Administrative Functions

Knowledge of Georgia licensing law, code compliance, and administrative procedure is what keeps a contracting business legally operating - and legally billing. Mistakes here create liability, not income.

  • Understanding Board rules protects your license and your contracts
  • Code compliance knowledge reduces inspection failures on commercial jobs

Domain 3: Installation

Installation competency, including the required lead-mechanic experience on systems exceeding 175,000 BTU heating and 60,000 BTU cooling, is the hands-on skill that commercial general contractors specifically look for when subcontracting mechanical work.

  • Lead-mechanic-level installation experience is a prerequisite, not optional
  • Large-tonnage installation experience differentiates Class II holders from entry-level techs

Domain 4: Maintain and Repair System

Service and repair work is often the steadiest revenue stream in the trade because it's recurring. EPA Section 608 Type II and Type III certification is required for this domain's real-world application.

  • Service contracts generate repeat billing, unlike one-time installs
  • Refrigerant handling certification (EPA 608) is non-negotiable for this work

Your Five Years of Experience Are Already an Earnings Asset

Before you can even sit for the exam, Georgia's current Class II law requires five years of full-time qualifying experience, broken into specific categories:

  • Two years of commercial supervisory experience
  • One year as a service technician or service supervisor
  • Two years of installation as a lead mechanic, with at least one commercial year on systems exceeding 175,000 BTU heating and 60,000 BTU cooling

This structure matters for earnings analysis because it means Class II candidates aren't entry-level workers studying for a credential to break into the trade - they're already supervisors, lead mechanics, and service leads by the time they qualify to test. The exam and license formalize a level of responsibility the candidate has typically already been performing. That existing supervisory and commercial track record is, functionally, an earnings asset independent of the license itself - the license simply makes that experience portable and legally recognized for unrestricted contracting.

Applicants also submit experience affidavits and references and pass a criminal background check as part of Board approval, which happens before scheduling is even possible. For the full eligibility breakdown, see the GA-CAC requirements guide.

Weighing the $110 Application Fee Against Career Investment

The Class II licensure-by-examination application fee is $110. On its own, that number tells you little - but in context, it's a small transactional cost compared to the years of qualifying experience, EPA certifications, and Board-approved heat-loss/gain and duct-design training (Manuals J&D and N&Q) candidates must already hold before they're even eligible to pay it. For a full pricing breakdown covering every cost component beyond the application fee itself, read the GA-CAC certification cost breakdown.

Cost Perspective: The $110 fee is the smallest financial commitment in the entire licensure path. The larger investment is time - five years of qualifying experience, EPA Type II/III certification, and Board-approved design training - all of which build earning capacity independent of the exam itself.

It's also worth noting that after two failed attempts, Georgia requires a Board-approved review course before a third exam attempt is permitted. That's a real cost consideration worth planning around, which is why a structured first-attempt strategy - outlined in the GA-CAC study guide for passing on your first attempt - has value beyond just the exam fee.

Who Hires Class II Licensed Contractors

Because the Class II license is unrestricted, holders are positioned for a wider range of employers and contract types than a restricted-scope license would allow. This includes:

  • Commercial mechanical contracting firms bidding on large-tonnage installation and retrofit work
  • Design-build HVAC firms that need staff capable of Manual J/D/N/Q-compliant load and duct calculations
  • Service and maintenance companies handling both residential and large commercial refrigerant systems under EPA 608 Type II/III authority
  • General contractors who need a licensed mechanical subcontractor of record for commercial projects

Continuing Education and Long-Term Income Stability

Earnings analysis isn't just about the day you pass the exam - it's about staying licensed and employable over time. Georgia Class II licenses renew by November 30 of odd-numbered years, and license holders must complete four CE hours per year, or eight hours per renewal cycle. This isn't a heavy burden compared to other licensed trades, but it's a recurring obligation that keeps your unrestricted scope active. Letting a license lapse means losing the very scope advantage that separates Class II earning potential from restricted-license work.

Key Takeaway

Your unrestricted scope only stays valuable if the license stays active. Budget CE hours (4/year, 8/renewal) into your ongoing professional routine, not just your initial exam prep.

Factors That Move Your Earning Ceiling

Rather than fabricate a salary chart, it's more accurate - and more useful - to look at the structural factors the Board itself has built into this license, and how each one plausibly affects the type and size of work you can pursue.

FactorWhat It ControlsEarnings Relevance
Unrestricted Class II scopeNo BTU/tonnage ceiling on eligible jobsOpens large commercial contracts unavailable to restricted licenses
System Design domain mastery (55% of exam)Manual J/D/N/Q-based load and duct design competenceQualifies you for design-build and consultative roles, not just install labor
Commercial installation experience (175,000 BTU+ heating / 60,000 BTU+ cooling)Lead-mechanic-level large-system experienceSignals readiness for high-value commercial bids
EPA 608 Type II & Type III certificationLegal authority to handle refrigerants across system typesRequired for recurring service and repair contract work
Active CE compliance (4 hrs/year)Ongoing license validityProtects continued eligibility for unrestricted contract work

Getting From Exam Day to Payday

The path to actually using this license commercially runs through the exam itself: two 3-hour 30-minute sections, 100 scored questions plus 20 unscored beta questions, computer-based and multiple-choice, with a minimum final scaled score of 70 required to pass. Only approved references may be used during testing - the 2024 Georgia Gas and Mechanical Codes with Georgia amendments and the 2023 NEC for exams scheduled May 1 through December 31, 2026 - and only permanent tabs, highlighting, and underlining are allowed in those references. Photocopies and handwritten notes are prohibited.

Knowing exactly what score you need and how the scaled scoring works removes a lot of exam-day anxiety; see the GA-CAC passing score breakdown for specifics. If you want a sense of how challenging candidates generally find the exam relative to their trade experience, the GA-CAC difficulty guide and pass rate analysis are useful companion reads. And because System Design carries more than half the exam's weight, it deserves proportionally more of your prep time - a scheduling point covered in depth in the GA-CAC study guide.

Once you're licensed, the practical next step is putting the unrestricted scope to work - bidding jobs, pursuing commercial contracts, and building the service base that turns a license into income. You can sharpen your exam readiness anytime using the practice testing tools on the main GA-CAC practice test platform, which mirrors the reference-permitted, multiple-choice format you'll see on exam day.

Bottom Line: This license doesn't come with a published salary table, but it comes with something more durable - an unrestricted scope of work, a heavily weighted design competency, and a renewal structure that rewards staying current. Those are the real levers behind long-term earning potential in this trade.

Frequently Asked Questions

Does the Georgia Construction Industry Licensing Board publish an official GA-CAC salary chart?

No. The Board publishes licensure requirements, exam structure, and renewal rules - not salary data. Earning potential is best understood through the license's unrestricted scope of work rather than a published pay scale.

Why does the Class II Unrestricted designation matter for earnings?

"Unrestricted" removes BTU and tonnage caps on eligible work, allowing license holders to pursue large commercial installation, maintenance, and repair contracts that restricted licenses cannot legally accept.

Which exam domain is most tied to higher-value work?

System Design, which makes up 55% of the exam, covers heat-loss/gain and duct-design competency using Manuals J, D, N, and Q - skills that qualify candidates for design-build and consultative commercial work.

Is the $110 application fee the biggest cost in pursuing this license?

No. The application fee is relatively small compared to the time investment of five years of qualifying experience, EPA Type II/III certification, and Board-approved design training required before you're eligible to apply.

What happens if my license lapses?

Licenses renew by November 30 of odd-numbered years with four CE hours required per year, eight per renewal cycle. Failing to renew means losing the unrestricted scope that supports higher-value commercial work.
