Do I need a permit for a hvac project in Oklahoma?

Replacement timelines: central AC swap 1 day; furnace swap 1–2 days; full split-system replacement 2–3 days; heat-pump install 2–4 days (longer in cold-climate states needing supplemental electric strip heat). Add 1–2 weeks lead-time for utility-rebate paperwork pre-approval. Oklahoma permit-review timelines and contractor availability can add 1–2 weeks during peak season (spring and early summer). Booking in late fall or winter often shortens the schedule.
