Furnace Rebates and Tax Credits in Tennessee (2026)
What expired, what is real right now, and which programs Clarksville homeowners should actually look into. No invented amounts, no stale credits.
Read This Before You Count on a Credit
Incentives for heating upgrades change often, and outdated advice is everywhere online. This page covers only programs we could verify as real, with exact sourcing. If a program's details could not be confirmed, we say so instead of guessing. That matters because the biggest federal incentive for furnaces just went away.
What expired: the federal 25C credit
Congress terminated the 25C Energy Efficient Home Improvement Credit for property placed in service after December 31, 2025. There is no federal tax credit for a furnace installed in 2026. Equipment installed by the 2025 deadline can still be claimed on the 2025 return via Form 5695. If a contractor is still advertising the 25C credit for new installs, that information is stale.

Programs That Are Real Right Now
TVA Home Uplift
Free home energy upgrades averaging around $10,000 per home for income-eligible customers of participating local power companies. Upgrades can include a new or repaired HVAC unit, plus insulation, air sealing, and appliances. Income qualifications apply, and the home must not have had similar TVA-funded upgrades in the last 20 years. Application line: 1-888-986-7262. One caveat for Clarksville: we have not verified whether CDE Lightband participates, so call CDE Lightband to confirm current participation before counting on it. Details: energyright.com.
TVA EnergyRight Rebates
Rebates for qualifying HVAC systems, duct and air sealing, insulation, and tune-ups, installed through TVA's Quality Contractor Network. Terms are set by each local power company, so they vary. Important for furnace owners: at least one TVA co-op requires the replacement heating unit to use electricity as its primary heat source, which can exclude gas-furnace replacements. Verify the current CDE Lightband terms by phone before you plan around a rebate.
THDA Weatherization Assistance
Tennessee's Weatherization Assistance Program is administered by THDA and delivered through community agencies covering all 95 counties, including Montgomery County. Households at or below 200% of the federal poverty level can qualify for free upgrades determined by a certified energy audit: air sealing, duct sealing, insulation, and heating or cooling system repair or replacement where the audit justifies it. Priority goes to elderly, disabled, and high energy-burden households. Source: thda.org.
LIHEAP Utility-Bill Help
LIHEAP is real, federally funded help with utility bills, also administered through THDA. What it is not: a repair program. It pays your energy supplier directly and does not pay HVAC contractors or cover furnace replacements. Benefit amounts change by program year, so check current figures with the administering agency rather than trusting last year's numbers.
How to Use This With Your Project
If your furnace is limping along and you are weighing replacement, check the programs above before you sign anything. Some require pre-approval or a specific contractor network, and applying after the work is done can disqualify you. When we quote a replacement, we will tell you which programs our customers have used and what we know about current terms, and we will point you to the utility or agency to confirm. We will not quote you a rebate amount we have not verified.

Rebate Questions
Rebates & Credits FAQs
Is the federal furnace tax credit still available in 2026?
No. Congress terminated the 25C Energy Efficient Home Improvement Credit for equipment placed in service after December 31, 2025. Equipment installed by that date can still be claimed on the 2025 return via Form 5695, but there is no federal credit for 2026 furnace installs. Be skeptical of any contractor still advertising it.
What is TVA Home Uplift and who qualifies?
TVA Home Uplift provides free home energy upgrades averaging around $10,000 per home for income-eligible customers of participating local power companies. Upgrades can include HVAC repair or replacement, insulation, and air sealing. Eligibility is income-based and the home must not have had similar TVA-funded upgrades in the last 20 years. The application line is 1-888-986-7262.
Does CDE Lightband offer furnace rebates right now?
We have not been able to verify current CDE Lightband residential rebate amounts or whether CDE Lightband participates in TVA Home Uplift. Call CDE Lightband directly to confirm current participation and any rebate offerings before counting on them. We will never quote you a rebate amount we have not verified.
Can a rebate or assistance program cover a full furnace replacement?
Sometimes, through the right program. TVA Home Uplift can include a new or repaired HVAC unit for qualifying households, and the THDA Weatherization Assistance Program can cover heating system repair or replacement when its energy audit justifies it. TVA EnergyRight rebates vary by utility, and at least one TVA co-op excludes gas-furnace replacements, so check the current terms with your utility first.
