HVACPermitGuide exists to answer one question that millions of US homeowners search every year: do I need a permit to replace my HVAC? The answer is genuinely complicated โ it depends on your state, your county, your project type, and whether you're hiring a contractor or doing it yourself. The current information landscape offers fragmented contractor blogs, siloed county government PDFs, and lead-gen platforms that obscure the answer behind forms.
We publish free, primary-source-verified permit guides for every US state โ with county-level depth where it matters most โ so homeowners can get a clear answer before spending $5,000โ$15,000 on HVAC work.
We cite state statutes (KRS 198B), administrative regulations (815 KAR 8:070), and published building department fee schedules โ not other websites.
Key fees and processes are verified by phone with the relevant building department before publication. We don't guess or extrapolate.
Every page carries a last-verified date. When requirements change, we update. Outdated information on permit requirements causes real financial harm to homeowners.
We don't sell leads, run contractor directories, or take advertising from HVAC companies. Our only revenue is Google AdSense and Amazon Associates.
We are not attorneys, contractors, or code officials. We state this clearly and recommend direct verification with building departments for final answers.
Our deepest coverage is the Northern Kentucky / Cincinnati metro โ where we have the strongest direct verification network. Boone County and Hamilton County guides are fully verified.

We believe in transparency about revenue. HVACPermitGuide earns money two ways:
Neither revenue stream influences our content. We have never received payment to recommend any contractor, jurisdiction, or HVAC product brand.
