HVAC Permits
Organize HVAC permit and load-calculation inputs.
HVAC permits for furnace, AC, heat pump, and mini-split installs. Permit Junkie ties Manual J/D/S to your jurisdiction's IMC/UMC edition.
Overview
Furnace & AC swaps
Project inputs can surface Manual J/D/S, line-set, and combustion-air questions; qualified professionals remain responsible for required calculations and design.
Heat pumps
Available evidence can surface outdoor-unit, electrical-load, and line-length questions for professional and authority review.
Mini-splits
Multi-zone manifold and condensate-drainage inputs can be organized for required professional design and authority review.
Frequently asked questions
- Do I always need a hvac permit?
- Requirements depend on the authority, property, and scope. Permit Junkie can compare your project with available jurisdiction records, but unresolved or stale authority information is labeled for confirmation with the issuing department.
- How long does a hvac permit take to approve?
- Approval time varies by authority, project complexity, review workload, and corrections. Permit Junkie shows a processing estimate only when a sourced record is available; confirm current timing with the issuing department.
