Iowa HVAC License Cost

The Exam Fees

Before you hold a license, you pay two testing fees:

• $35 — PMSB exam pre-approval application (per trade discipline)
• $119 — Kirkwood Community College exam administration fee (per attempt)

That's $154 for a single successful exam attempt. If you fail and retake, the $119 Kirkwood fee applies again; the $35 PMSB pre-approval fee is separate from Kirkwood's per-attempt fee.

Individual License Fees (Prorated)

Iowa licenses run on a fixed three-year cycle — currently July 1, 2026, through June 30, 2029. Your license fee is prorated based on when you apply within the cycle, not calculated from your start date.

Full-term fees for applications filed July–December of Year 1:

• Apprentice: $50
• Journeyperson: $180
• Master: $240

Filing later reduces the cost proportionally. An application in January–June of Year 2 runs $90 for journeyperson, $120 for master. By January–April of Year 3, it's $30 for journeyperson and $40 for master.

Filing during May–June of Year 3 triggers the "hybrid rule" — you pay the remaining Year 3 prorated fee plus the full fee for the next cycle, so the license carries through the end of the following three-year term.

Contractor License and Registration

To operate a business, you file a joint application covering both the PMSB contractor license and the DIAL contractor registration. Full-term joint fee (Year 1): $400 ($250 PMSB license + $150 DIAL registration).

Paper applications add a $25 processing fee. Online filing through the DIAL portal avoids this.

The prorated schedule follows the same cycle:

Insurance and Bonding Costs

These aren't state fees — they're commercial costs, and the applicable items are part of the contractor requirements:

• $500,000 public liability insurance — Annual premiums vary by insurer, business, and claims history; obtain quotes
• $5,000 performance surety bond — Premiums vary by applicant and surety; obtain a quote
• $25,000 out-of-state bond (non-resident contractors only) — Premium runs 1–5% ($250–$1,250) depending on your credit profile
• Workers' compensation insurance — Required if you have employees. Rates vary by payroll and classification code

The Multi-License Discount

If you apply for or renew multiple licenses on the same day, the PMSB offers a 30% discount on the combined license fees. The calculation:

1. Sum all journeyperson, master, and contractor license fees
2. Multiply by 0.70
3. Add the $150 contractor registration fee (not discountable)
4. Add the $25 paper fee if applicable

Example: A new master license ($240) plus a contractor license ($250) filed together = $490 × 0.70 = $343, plus $150 registration = $493 total instead of $640. That's a $147 savings.

The discount only applies to on-time applications. Late submissions lose the discount and add $60–$100 per license in penalties.

Total First-Year Cost Estimate

For a new contractor filing a joint application in Year 1 of the cycle with a single HVAC-Refrigeration master license:

That $794 subtotal is before commercial insurance and bond premiums and excludes any multi-license discount and workers' comp (if you're a sole proprietor with no employees). Add another $250–$1,250 for the out-of-state bond if your business is based outside Iowa.
