Tennessee's Board for Licensing Contractors requires a contractor license with the CMC-C (HVAC) classification for HVAC projects of $25,000 or more. Most smaller HVAC projects are regulated by the city or county where the work is done, and some counties require a state Home Improvement license for HVAC work under $25,000. Before hiring, verify your contractor's credentials through the board's license lookup tool. Also ask for proof of insurance and confirm who will pull the permit. See our safety tips for more on what to verify before hiring.

Check with the state energy office for current program status. Under DOE Program Notice 26-2 (effective May 29, 2026), HEEHR rebates no longer cover replacing gas or other non-electric equipment; they cover upgrades from existing electric equipment to more efficient electric equipment.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). Check your state energy office and utility for current rebate programs. See our HVAC financing options for what's still available.
