Tennessee mini-split cost guide

Much of Tennessee is climate zone 3 / 4. Electricity here runs 14.47 cents per kilowatt-hour, so a typical 12,000 BTU system costs about $431 a year to run. One rebate program below can cut the installed price. Installed prices are mostly national — labor is the part that varies locally.

Equipment, materials, electrical work and permits are priced the same everywhere. Only the labor line is adjusted to this state, which is why these ranges sit close to the national ones.

Code Notes

  • Tennessee mechanical permit fees are local. Nashville provides a municipal data point: its gas/mechanical permit fee schedule has a $75 minimum permit fee and an HVAC replacement or alteration line priced at $32 per 100,000 Btuh or fraction. Actual permit scope and fees are decided by the local authority having jurisdiction.
