Tips

  • New-construction HVAC in Parker is more rigorous than a simple permit — it requires full Manual J/S/D documentation and both rough and final duct-testing, not just an equipment permit.
  • A model that has already passed the Town's required testing can be built repeatedly without re-testing, as long as the installation doesn't deviate from the approved mechanical plan.
