Kansas HVAC Technician License: County & City Rules (No State Board)

Kansas does not issue a statewide HVAC technician license — licensing happens at the county and city level. Who actually licenses HVAC technicians and where to check, verified from official sources.

Requirements at a glance

No Kansas state license exists (nothing to apply for at the state level): Kansas issues no statewide HVAC, air conditioning, refrigeration, heating or mechanical-contractor license, and has no state contractor-licensing board. The state agency that licenses the design-and-construction professions - the Kansas State Board of Technical Professions - regulates only architecture, engineering, geology, landscape architecture and land surveying (its own site lists exactly those five 'professions'); it does not license HVAC, mechanical, plumbing or electrical trades or contractors. The one construction-trade credential Kansas maintains at the state level is a roofing REGISTRATION administered by the Attorney General under the Kansas Roofing Registration Act (K.S.A. 50-6,121 et seq.) - a registration certificate, not a competency license, and it applies to roofing only. Every HVAC/mechanical credential in Kansas is issued below the state level by a city or county under Kansas home-rule authority.
Johnson County (Kansas City metro suburbs) - Class DM Mechanical Contractor License: Johnson County Contractor Licensing (a division of Planning, Housing and Community Development) issues and tracks 11 construction-contractor license types, including the Class 'DM' Mechanical Contractor License, which 'shall entitle the holder thereof to perform only HVAC, mechanical, and refrigeration services.' A Class A, B or C general/building/residential license expressly does NOT authorize HVAC work, so mechanical contractors must hold the DM license. The license is held by the COMPANY; its Qualifying Individual proves competency by an ICC/Prometric standard exam scored 75% or better (as approved by the Contractor License Review Board) OR a Bachelor of Science in Architecture, Construction Science, Mechanical Engineering or relevant Engineering (ABET/ACCE). The company must carry general liability insurance (ACORD form listing the county's office as certificate holder) and workers' compensation if it has employees (or a notarized waiver), plus a Secretary of State Certificate of Good Standing if applicable. Fees: $100 application (new licenses only) + $225 license fee per license type; renewal $225 per type, late fee $75 applied Feb. 1. Every license ends December 31 regardless of when issued (annual, calendar-year term). Address: 111 S. Cherry St., Suite 1000, Olathe, KS 66061; 913-715-2233.
Sedgwick County & City of Wichita - MABCD mechanical trade contractor license + Master/Journeyman Mechanical trade certificate: The Metropolitan Area Building and Construction Department (MABCD) licenses contractors and certifies tradespeople for unincorporated Sedgwick County, the City of Wichita, and the small cities contracted into MABCD's jurisdiction. The mechanical (HVAC) path has two parts: the company obtains a Trade Contractor License (MABCD Form #45A/#45B), and the qualified person holds a MASTER MECHANICAL trade certificate. Individual tradespeople must be certified: 'MABCD requires that journeyman and master trades people (electrical, mechanical and plumbing) get trade certificates to work in Sedgwick County and the City of Wichita.' JOURNEYMAN MECHANICAL: one year of field experience AND one year of mechanical trade school, OR two years of field experience, AND a score of 75% or better on ICC K9G/559 Journeyman Mechanical or an IAPMO exam. MASTER MECHANICAL: a mechanical journeyman AND two years of field experience as a journeyman, OR four years of field experience, AND 75% or better on ICC K9L/556 Master Mechanical or IAPMO (MABCD does not reciprocate with state testing - only its approved ICC/IAPMO exams count). Trade certificate fee: $35. The contractor license requires a Certificate of Liability insurance of at least $300,000 general liability (MABCD as certificate holder), workers' compensation (or a notarized waiver), auto insurance (or waiver), and a Kansas Secretary of State Certificate of Good Standing (not required for sole proprietors). Certificates are valid two years; renewal requires 12 continuing-education hours per cycle (six trade-specific plus six general trade CEUs). MABCD: 271 W. 3rd, Suite 101, Wichita, KS 67202; 316-660-1840.
City of Topeka - Mechanical Contractor license (Development Services Division): The City of Topeka Development Services Division 'is responsible for issuing all contractor and trade licenses in the City of Topeka,' and 'Mechanical Contractor' is one of its published license categories (alongside electrical, plumbing, general, excavation and specialty). 'All trades are required to be licensed and pull permits to work in City of Topeka.' Competency is proven by a passing ICC certification (or approved alternative education) submitted with the application, together with a Certificate of Liability Insurance and workers' compensation (listing City of Topeka Development Services, 620 SE Madison Unit 6, Topeka, KS 66607-1118, as certificate holder; a notarized affidavit substitutes where workers' comp is not required). The licensing term runs from the date the license is processed until December 14 of that year and fees are not prorated; all licenses must be renewed each year by December 14 to avoid late fees, and a $30 reinstatement fee applies if insurance lapses beyond a 30-day grace period. Continuing education: a trade contractor's designated master or journeyman must obtain 6 hours of continuing education per year, 3 of which must be in their trade (Class A/B/C contractors need 8 hours per year). Topeka's published contractor pages block automated retrieval, so specific Topeka fee dollar amounts are omitted here rather than sourced to a non-official page - confirm current fees with Development Services.
Other Kansas cities and counties license HVAC too - check the specific jurisdiction: This record covers the three largest Kansas licensing jurisdictions (Johnson County, Sedgwick County/Wichita, and Topeka). Other cities and counties - including Kansas City, Kansas (Unified Government of Wyandotte County), Overland Park, Lenexa, Olathe, Lawrence and many others - set their own HVAC/mechanical licensing and permit rules, and some Johnson County cities administer requirements in addition to the county program. Because Kansas has no state HVAC license and no single statewide dataset, a contractor must identify the exact city or county where the work will be performed and confirm that locality's rules before bidding. Do not assume one Kansas jurisdiction's rules apply in another.
FEDERAL (everywhere in Kansas) - EPA Section 608 refrigerant certification: Separate from every Kansas city and county license: under the Clean Air Act and 40 CFR part 82, subpart F, technicians who maintain, service, repair or dispose of equipment that could release refrigerant must hold EPA Section 608 certification. This is a FEDERAL credential, held by the individual technician, and it is neither issued by nor accepted in place of any Kansas local HVAC/mechanical license or trade certificate. Holding EPA 608 does not satisfy Johnson County's DM license, a Sedgwick County/Wichita mechanical trade certificate, or a Topeka mechanical license.

Legal basis

Kansas does not license HVAC technicians at the state level.

Kansas does not license HVAC. There is no statewide HVAC, air conditioning, refrigeration, heating or mechanical-contractor license, no state contractor-licensing board, no state exam and no state fee schedule - so there is nothing to apply for at the state level. The state agency that licenses the design-and-construction professions is the Kansas State Board of Technical Professions, and its own site lists exactly five regulated professions - architecture, engineering, geology, landscape architecture and land surveying - none of which is HVAC, mechanical, plumbing or electrical work. The only construction-trade credential Kansas maintains at the state level is a roofing REGISTRATION run by the Attorney General under the Kansas Roofing Registration Act (K.S.A. 50-6,121 et seq.); it is a registration certificate rather than a competency license and it covers roofing only - there is no equivalent state registration or license for HVAC. Kansas HVAC licensing is therefore delegated to cities and counties under Kansas home rule, and the positive proof of that runs the other way, from the local programs that expressly claim the work.

The three largest jurisdictions each license mechanical/HVAC work, but in different shapes, so the credential you need depends on where you work. JOHNSON COUNTY (the populous Kansas City suburbs) licenses the COMPANY: its Contractor Licensing division issues a Class ‘DM’ Mechanical Contractor License that ‘shall entitle the holder thereof to perform only HVAC, mechanical, and refrigeration services,’ and it makes clear that a Class A, B or C general/building/residential license does NOT authorize HVAC. The company’s Qualifying Individual proves competency with an ICC/Prometric standard exam at 75% or better (or a relevant BS degree), and the company carries general liability insurance and workers’ compensation (or a waiver). Fees are $100 application plus $225 per license type, every license expires December 31, and an employed technician working for the licensed company needs no separate county license.

SEDGWICK COUNTY AND THE CITY OF WICHITA license through the Metropolitan Area Building and Construction Department (MABCD), and here INDIVIDUALS are certified in addition to the company: ‘MABCD requires that journeyman and master trades people (electrical, mechanical and plumbing) get trade certificates to work in Sedgwick County and the City of Wichita.’ A journeyman mechanical certificate takes one year of field experience plus one year of mechanical trade school (or two years of field experience) and a 75%-or-better score on ICC K9G/559 Journeyman Mechanical or an IAPMO exam; a master mechanical certificate takes a journeyman plus two more years as a journeyman (or four years of field experience) and 75% on ICC K9L/556 Master Mechanical or IAPMO. The trade certificate is $35, the trade contractor license requires at least $300,000 in general liability insurance, and certificates run two years with 12 continuing-education hours per cycle (six trade-specific and six general). MABCD’s jurisdiction reaches unincorporated Sedgwick County, Wichita, and the small cities contracted into it.

THE CITY OF TOPEKA licenses through its Development Services Division, which ‘is responsible for issuing all contractor and trade licenses in the City of Topeka,’ publishes a ‘Mechanical Contractor’ license category, and states that ‘all trades are required to be licensed and pull permits to work in City of Topeka.’ Applicants submit a passing ICC certification (or approved alternative education), a Certificate of Liability Insurance and workers’ compensation; the term runs to December 14 each year (no proration), and a trade contractor’s designated master or journeyman must complete 6 continuing-education hours a year, 3 of them in-trade.

Other Kansas localities - Kansas City, Kansas (Unified Government of Wyandotte County), Overland Park, Lenexa, Olathe, Lawrence and many more - regulate HVAC work under their own codes and permit rules, and some Johnson County cities layer their own requirements on top of the county program. This record covers the three largest jurisdictions and says so; identify the exact city and county of the job and confirm before bidding.

Finally, and separately from every Kansas license: EPA Section 608 certification is FEDERAL. Under the Clean Air Act and 40 CFR part 82, subpart F, anyone who maintains, services, repairs or disposes of equipment that could release refrigerant must be Section 608 certified. It applies everywhere in Kansas, it is held by the individual technician, and it is not a substitute for - or a component of - any city or county HVAC/mechanical license or trade certificate.

What it’s called

Kansas does not license HVAC technicians or contractors at the state level; a search for a ‘Kansas HVAC license’ maps to a LOCAL (city or county) credential. Depending on the jurisdiction that credential is a ‘mechanical contractor license’ (Johnson County calls it the Class ‘DM’ license; the City of Topeka lists a ‘Mechanical Contractor’ license) or a ‘mechanical (HVAC) trade certificate’ for individual journeymen and masters (Sedgwick County / City of Wichita, through MABCD). Common informal names - ‘HVAC license,’ ‘AC license,’ ‘air conditioning license,’ ‘mechanical license’ - all resolve to one of these local credentials, and the word ‘refrigeration’ appears in Johnson County’s DM scope. Separately, EPA Section 608 refrigerant-handling certification is a FEDERAL credential, not a Kansas or local HVAC license, and is commonly confused with one. There is no statewide Kansas HVAC license to search for.

Who does NOT need a license — exemptions

Kansas licenses no HVAC occupation at the state level, so the operative carve-outs are local and differ by jurisdiction - there is no single statewide exemption list. Three patterns from the largest jurisdictions: (1) EMPLOYEE / COMPANY-LICENSE STRUCTURE - Johnson County licenses the contracting COMPANY (the Class DM Mechanical Contractor License) and its Qualifying Individual, so a technician employed by that licensed company needs no separate county license; by contrast, Sedgwick County/Wichita (MABCD) and Topeka require individual master/journeyman tradespeople to hold their own trade certificates even when the company is licensed - so ’employed technicians are exempt’ is TRUE in Johnson County but NOT a safe assumption in Wichita or Topeka. (2) HOMEOWNER work - Sedgwick County MABCD does not simply exempt homeowners: it ‘requires homeowners to pass electrical, plumbing, water heater and mechanical exams if a homeowner wants to do specific work on his/her owned and occupied home,’ so even an owner-occupant doing his own mechanical work faces a competency exam there; other jurisdictions set their own homeowner rules. (3) ROOFING vs HVAC - the one Kansas STATE registration (roofing, via the Attorney General) has its own statutory exemptions and does not touch HVAC. Because exemptions are set ordinance-by-ordinance, an HVAC contractor must read the specific city/county code where the work will be performed; this record states what the three largest jurisdictions publish and does not generalize a single Kansas-wide exemption.

Where to get licensed

There is no statewide Kansas board to call. Identify the city and county where the work will be performed, then go to that locality’s licensing authority.

IN THE KANSAS CITY SUBURBS (Johnson County): apply to Johnson County Contractor Licensing for a Class DM Mechanical Contractor License (111 S. Cherry St., Suite 1000, Olathe, KS 66061; 913-715-2233). Have ready your Qualifying Individual’s ICC/Prometric exam result (75%+) or a relevant BS degree, general liability insurance naming the county’s office as certificate holder, workers’ compensation (or a notarized waiver), and a Secretary of State Certificate of Good Standing if applicable. Budget $100 application + $225 per license type; the license expires December 31. Some Johnson County cities have additional requirements - confirm with the city too.

IN WICHITA / SEDGWICK COUNTY: apply to MABCD (271 W. 3rd, Suite 101, Wichita, KS 67202; 316-660-1840). The company needs a mechanical Trade Contractor License; the qualified person needs a Master Mechanical trade certificate, and journeymen and masters working the trade need their own certificates. Requirements include the ICC or IAPMO mechanical exam at 75%+, documented field experience (and trade school for the shorter journeyman path), at least $300,000 general liability insurance, workers’ comp and auto insurance (or waivers), and a Kansas Secretary of State Certificate of Good Standing. Trade certificate fee is $35; certificates run two years and require 12 CEUs (6 trade-specific + 6 general) per cycle. MABCD requires an appointment for its licensing office.

IN TOPEKA: apply to the City of Topeka Development Services Division (620 SE Madison Unit 6, Topeka, KS 66607-1118) for a Mechanical Contractor license. Submit a passing ICC certification (or approved alternative education), a Certificate of Liability Insurance and workers’ compensation. Licenses run to December 14 each year (no proration), and the designated master or journeyman must complete 6 hours of continuing education a year (3 in-trade). Confirm the current fee schedule with the division.

FOR EVERY OTHER KANSAS CITY OR COUNTY (Kansas City/Wyandotte County, Overland Park, Lenexa, Olathe, Lawrence and the rest): contact that locality’s building or development-services office directly - this record does not cover them and no statewide rule fills the gap.

EVERYWHERE IN KANSAS: if your work involves refrigerants, get EPA Section 608 certification. That is a FEDERAL credential (40 CFR part 82, subpart F), held by the individual technician, and it is separate from every Kansas license above.

Frequently asked questions

Does Kansas require a state HVAC license?

No. Kansas issues no statewide HVAC, air conditioning, refrigeration or mechanical-contractor license and has no state contractor-licensing board. The state board that licenses the construction professions - the Kansas State Board of Technical Professions - covers only architecture, engineering, geology, landscape architecture and land surveying, not the HVAC/mechanical trades. The only state-level construction-trade credential is a roofing registration run by the Attorney General, and it covers roofing only. The HVAC credential you need is issued by the city or county where you work.

Where do you actually get an HVAC/mechanical license in Kansas?

From the local jurisdiction. In the Kansas City suburbs, Johnson County Contractor Licensing issues a Class DM Mechanical Contractor License. In Wichita, the Sedgwick County MABCD licenses mechanical trade contractors and certifies master and journeyman mechanical tradespeople. In the capital, the City of Topeka Development Services Division issues a Mechanical Contractor license. Other Kansas cities and counties (Kansas City/Wyandotte County, Overland Park, Lenexa, Olathe, Lawrence and more) have their own rules - always confirm with the specific locality before bidding.

Does an individual technician need a license, or just the company?

It depends on the jurisdiction, which is a key Kansas trap. Johnson County licenses the COMPANY (the Class DM license); a technician employed by that licensed company needs no separate county license, and the company’s Qualifying Individual satisfies the exam/education requirement. Wichita/Sedgwick County (MABCD) is different: individual journeyman and master mechanical tradespeople must hold their own trade certificates in addition to the company’s trade contractor license. Topeka likewise licenses trades and expects a designated master or journeyman. Check whether your locality certifies individuals, the company, or both.

What experience and exams do the big Kansas jurisdictions require for HVAC?

Johnson County accepts an ICC/Prometric standard exam at 75% or better (or a relevant Bachelor of Science degree) for the Class DM license. Wichita/Sedgwick County requires, for a journeyman mechanical certificate, one year of field experience plus one year of mechanical trade school (or two years of field experience) and 75% on ICC K9G/559 Journeyman Mechanical or an IAPMO exam; a master mechanical certificate adds two more years as a journeyman (or four years of field experience) and 75% on ICC K9L/556 Master Mechanical or IAPMO. Topeka accepts a passing ICC certification or approved alternative education. All three require liability insurance, and Wichita and Topeka require continuing education to renew.

Do I still need EPA 608 certification in Kansas?

Yes, if you handle refrigerants. EPA Section 608 certification is a federal requirement under the Clean Air Act (40 CFR part 82, subpart F) for anyone who maintains, services, repairs or disposes of equipment that could release refrigerant. It applies everywhere in Kansas, it is held by the individual technician, and it is separate from - and does not satisfy - any city or county HVAC/mechanical license or trade certificate.
