License and Insurance
Hiring an HVAC contractor without checking credentials is something you only get away with until you don’t. Combustion appliances, refrigerant handling, gas lines, and electrical work each carry their own risks, and licensing exists because those risks deserve actual training. Here are 7th Degree Heating and Air’s credentials, in plain language, with the numbers you can verify.
Johnson County Mechanical License
Kansas doesn’t issue a statewide HVAC license — the trade is regulated at the county level. In Johnson County, residential and commercial HVAC work requires a Class “DM” Mechanical Contractor License, which covers heating, cooling, ventilation, and refrigeration. It’s not a permit-issuing rubber stamp; the test, experience requirements, and continuing education are real, and licenses can be looked up and verified.
- Issuing authority: Johnson County, Kansas
- License class: Class “DM” Mechanical Contractor
- License number: DM-24-11873
EPA Section 608 Universal Certification
Federal law — Section 608 of the Clean Air Act — requires technicians who handle refrigerant to be certified, with separate certifications for low-pressure, high-pressure, and small appliances. Universal certification covers all three. It also means a technician is trained and authorized to recover, recycle, and handle refrigerants properly — including the older R-22 still found in some Leawood-area systems, the R-410A that dominated through 2024, and the R-454B that took over with the 2025 transition.
- Issuing authority: U.S. Environmental Protection Agency
- Certification level: Section 608 Universal
- Certification number: EPA-608-U-457921
Insurance
We carry the insurance a working HVAC contractor should have: general liability protecting your property in the event of damage during our work, and workers’ compensation covering anyone on our team while they’re on your job. Insurance certificates and current proof of coverage are available on request — just call the office and we’ll get a certificate sent over.
Why It Matters
Licensing isn’t just paperwork. A licensed contractor pulls real permits through the Johnson County building department on installations — meaning the work is inspected and meets code, which protects your warranty and your homeowner’s insurance position. EPA certification means refrigerant is recovered properly rather than vented to the atmosphere (which is illegal and environmentally damaging). Carrying insurance means a stray accident on your property doesn’t become your problem. Asking an HVAC contractor for their credentials should never feel rude — it’s just due diligence, and any reputable company will hand them over without hesitation.
Frequently Asked Questions
- Where can I verify your Johnson County license?
- The Johnson County contractor licensing department maintains a public lookup; our license number is DM-24-11873 (Class “DM” Mechanical Contractor). You’re welcome to verify directly with the county.
- Why isn’t there a Kansas state HVAC license?
- Kansas regulates HVAC contractors at the county level rather than statewide, so the relevant credential here is Johnson County’s Class “DM” license. That’s why a contractor licensed in another Kansas county doesn’t automatically have authority here — or vice versa.
- What does EPA 608 Universal actually cover?
- Section 608 has three certification levels for different refrigeration system types; Universal covers all three. It authorizes a technician to legally purchase, handle, recover, and recycle refrigerants — which is required for any work that opens a refrigerant circuit. Hiring someone without it is a real risk.
- Can I see your insurance certificate?
- Yes. Call the office and we’ll send a current Certificate of Insurance from our carrier. We do this routinely for HOAs, property managers, and individual homeowners who ask.
- Do you pull permits when required?
- Yes. Installations that require a permit get one pulled through Johnson County, and the work is inspected. It protects your warranty, your homeowner’s insurance position, and the integrity of the install — well worth the small additional time.
