Most larger hvac repair jobs in Peoria need a permit and inspection; repairs often do not. Here is what to check before work starts.
Check the official Peoria permit portal: https://www.peoriaaz.gov/government/departments-divisions/planning-community-development/building-safety. Replacements, re-piping and new installs typically need a permit; simple repairs usually do not. Ask the contractor in writing who will handle filing and inspection, and whether those fees are included.

Licence and certification requirements depend on the work and jurisdiction. Ask which requirement applies, then verify the provider at the official lookup before work begins.
