Set by local rules
Do you need a permit for HVAC Installation in Mohave County?
In Arizona, there is no single statewide rule for a HVAC Installation; whether you need a permit is decided locally in Mohave County.
There is no statewide mechanical code, so the rule is set by your local jurisdiction, but virtually all jurisdictions require a mechanical permit for HVAC installation or replacement. A gas-to-heat-pump conversion also typically needs an electrical permit. Because Arizona leaves this to local jurisdictions, the reliable answer comes from Mohave County Planning Department. Zoning setbacks apply either way.
