Maryland HVAC contractor license cost FAQs
Is the state license fee separate from the PSI exam fee?
Yes. You first pay PSI ($150 Master/Limited; $50 per Master Restricted specialty) to take the exam. After passing, you pay the Board’s license fee ($94.50 Master or Limited; $31.50 per Master Restricted area) when you apply/activate your license (PSI Bulletin; Board fees).
How often will I pay renewal fees, and how much?
Every two years. Under §9A‑309, HVACR licenses renew on a 2‑year cycle, expiring on the first October 1 that comes after issuance in an odd‑numbered year. Renewal fees match original issuance: $94.50 (Master/Limited) or $31.50 per Master Restricted area (statute; fee schedule).
What insurance proof do I need and does it affect cost?
To contract HVACR work, you must maintain at least $300,000 general liability and $100,000 property‑damage coverage (combined ≥ $400,000) and name the Board as certificate holder. Premiums are market‑based and vary by business; the regulation sets minimum coverage, not price (insurance rules).
Are there continuing education costs?
No Board‑mandated CE. The HVACR Board does not require continuing education for renewal, so there’s no CE fee to budget at the state level (Board education policy).
How long does it take to be licensed after passing?
PSI indicates document review can take up to one week after you submit required materials; after you pass, the Board typically mails instructions to register your license within about 10 business days (PSI Bulletin; Board FAQs).

Costs beyond the state fee: budgeting smart for Maryland HVAC contractors
Beyond the exam and license fee, most HVAC startups will budget for local permits, vehicle signage (Board‑required category/number), tools, EPA Section 608 certification, and insurance premiums.
