How to get licensed
- 1
Meet the prerequisites
Meet the eligibility requirements set by the issuing board. No minimum age or criminal-background-check requirement is stated on the board's official licensing page for Low Voltage/Limited Technician licenses. Applicants must document 2 years (4,000 hours) of qualifying work experience via notarized employer letters or the official work-verification form, and must be employed by a Wyoming-licensed Low Voltage/Limited Contractor to perform this work. A valid government-issued ID and a personal (non-employer) email address are required to apply. [1]

Complete approved training
Complete 4000 hours of training. Wyoming has no statewide license for general HVAC mechanical/installation/refrigerant work — that is regulated only locally (e.g., Cheyenne and Casper each run their own mechanical contractor/journeyman licensing). The only state-level HVAC-related credential is the Limited Technician – HVAC (LM-H) license from the Department of Fire Prevention and Electrical Safety, officially defined as 'limited electrical work for heating, ventilating and air conditioning systems limited to electrical work on the load side of the equipment disconnect.' It requires 2 years (4,000 hours) of documented qualifying work experience (notarized employer letters or the official employment-verification form) — not a classroom training-hour requirement or an accredited program, so approvedProgramRequired is false. It does NOT cover ductwork, refrigerant handling, gas piping, or general mechanical HVAC work. [1]

Wyoming Limited HVAC Technician Examination (ICC Exam #600)
Pass the Wyoming Limited HVAC Technician Examination (ICC Exam #600) (fee: $115). 40 multiple-choice questions, open book, 2-hour time limit. Content: general knowledge/theory/load calculations, feeders/branch circuits/conductors, wiring methods (load side of disconnect to equipment/motor), control circuits (incl. thermostat wires), equipment grounding/bonding, and HVAC equipment/motors (load side of disconnect) — largest content share (about half the exam). Exam scope confirms the license covers only electrical wiring to HVAC equipment on the load side of the disconnect, not mechanical/refrigerant work. [2]

Submit your application
Submit your application to Wyoming State Fire Marshal's Office, Electrical Board (Department of Fire Prevention and Electrical Safety). Typical processing time: The board's licensing page states application processing 'can take 5 business days to process each step' of the multi-step application/exam-eligibility/licensing workflow (depending on volume), and that the 'available for payment' email for the initial license can itself take several business days during high-volume periods..

Receive your license
Once your application is approved, Wyoming State Fire Marshal's Office, Electrical Board (Department of Fire Prevention and Electrical Safety) issues your Limited Technician – HVAC (LM-H) — electrical wiring on HVAC equipment only for Wyoming.
Fees
| Fee | Amount |
|---|---|
| Application fee [1] | None specified |
| License fee [1] | $100 |
| Renewal fee [1] | $50 |
| Wyoming Limited HVAC Technician Examination (ICC Exam #600) [2] | $115 |
| Limited HVAC Technician exam fee (PearsonVUE/ICC Exam #600) [1] | $115 |
Per the board's licensing page, after passing the exam an applicant uploads the passing letter to obtain the initial Limited Technician license for $100.00; renewal is $50.00 every 3 years. No separate pre-exam 'application' fee distinct from the $100 initial-license fee was found for this license category, so application is left null. A 2.5% credit/debit processing fee (min. $1.00) applies to online payments per Wyo. Stat. § 9-4-217(h).
Renewal & continuing education
Renew every 3 years.
The Limited Technician – HVAC license is valid for 3 years and renews on July 1st of every third year, for a $50.00 renewal fee. The board's licensing page states a 16-hour continuing-education requirement (8 of which must be NEC-specific) for Journeyman and Master Electrician renewals, but states no CE-hour requirement for Low Voltage/Limited Technician licenses (including Limited HVAC Technician); left null rather than assumed.
Reciprocity
No reciprocity or endorsement route was found.
The board's licensing page states that Low Voltage/Limited Technician licenses (including Limited HVAC Technician) 'can only be obtained through examination.' Wyoming's electrician reciprocity agreements with other states apply only to Journeyman and Master Electrician licenses, not to Limited Technician categories. No interstate licensure compact covers this occupation, and Wyoming is not a member of any HVAC-related compact.
