Most larger hvac repair jobs in Aurora need a permit and inspection; repairs often do not. Here is what to check before work starts.
Check the official Aurora permit portal: https://www.auroragov.org/residents/community_development/building_division. 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.
