Indoor air handlers and furnaces must meet fire safety clearances

HVAC systems must include programmable thermostats for temperature regulation and energy savings.

What’s the HVAC Permit Process Like?

Here’s how a typical HVAC permit process works in Tempe:

Contractor Applies: Your licensed HVAC contractor (like Einstein Pros) submits plans and the permit application to the city.
Plan Review: City reviews for compliance with codes.
Permit Issued: Work can begin once approved.
Installation: Contractor installs HVAC system per code.
Inspection: City inspector visits the site to verify proper installation.
