How Tennessee homes are heated
Electricity is the main heating fuel in 1,072,710 of Tennessee’s 1,890,569 owner-occupied homes, or 56.7%, in the Census Bureau’s table B25117 for 2020-2024. Only five states have a higher electric share. Utility gas covers 36.5%, bottled, tank or LP gas 4.5% and wood 1.4%.
| Heating fuel | Owner-occupied homes | Share | Source |
|---|---|---|---|
| Electricity | 1,072,710 | 56.7% | ACS 2020-2024, B25117 |
| Utility gas | 689,927 | 36.5% | ACS 2020-2024, B25117 |
| Bottled, tank or LP gas | 84,572 | 4.5% | ACS 2020-2024, B25117 |
| Wood | 26,966 | 1.4% | ACS 2020-2024, B25117 |
| Fuel oil, kerosene, solar, coal and other fuels | 9,324 | 0.5% | ACS 2020-2024, B25117 |
| No fuel used | 7,070 | 0.4% | ACS 2020-2024, B25117 |
Counting renters as well, 63.7% of the state’s 2,824,277 occupied homes heat with electricity in table B25040 (2020-2024 ACS). Buyers look at the fuel mix because it fixes the replacement path: an electric home usually swaps one heat pump or electric furnace for another, while a gas home pairs a furnace with a separate cooling unit. None of these shares measures where requests come from.
Tennessee heating and cooling needs in degree days
Tennessee ran hotter than normal in 2025. NOAA’s Climate at a Glance cooling degree day series records 1,571 for the year against a 1991-2020 average of 1,416, which placed the state 12th of the 48 with a statewide series.
Heating need was lighter than usual: 3,549 heating degree days in 2025 compared with a 1991-2020 average of 3,754 in the heating series. Even so, the heating total is more than double the cooling total, so Tennessee systems work hard in both seasons, which suits heat pumps that both heat and cool.
About the figures: a degree day is the gap between a day’s mean temperature and 65°F. The 2025 numbers are January-December sums from the NCEI statewide series, and the averages are the means of the annual values for 1991 through 2020 in the same series.
Tennessee HVAC contractor licensing
This section is general information, not legal advice. It summarizes official sources as of October 8, 2026; check the current text of each rule before relying on it.
Tennessee licenses contractors through the Board for Licensing Contractors in the Department of Commerce and Insurance. HVAC work sits in the mechanical group of the board’s classification outline (checked October 8, 2026):
- CMC (full mechanical): covers all mechanical subcategories and requires a trade exam.
- CMC-C: HVAC, refrigeration and gas piping, plus solar HVAC (geothermal). A trade exam is required.
- CMC-J: fuel gas piping and systems, with no trade exam.
- CMC-H: pneumatic temperature controls, with no trade exam.
The board’s contractor license page (checked October 8, 2026) adds that a subcontractor working for another contractor must be licensed for HVAC or mechanical work when that portion of the project is $25,000 or more, counting materials, equipment and labor. The outline repeats the point: mechanical subcontractors on work over $25,000 must hold a contractor license. Refrigerant handling also requires federal technician certification under EPA Section 608.
Tennessee owners and renters in HVAC terms
Tennessee has 1,890,569 owner-occupied homes and 933,708 renter households among 2,824,277 occupied homes, per table B25003 (ACS 5-year 2020-2024). Owners are about two in three households, and they are the people who pay for a full system replacement; renters usually report a failure to a landlord, who then hires the contractor.
Building age, the energy code and climate zone details are covered on Tennessee window replacement leads rather than repeated here.
Status of Tennessee’s home energy rebate programs
TDEC’s Office of Energy Programs acts as Tennessee’s state energy office. Its Home Energy Rebate Programs page (checked October 8, 2026) describes two federally funded programs: HOMES, for whole-home efficiency retrofits, and HEEHR, which covers upgrades of HVAC and appliances from existing electric equipment to more efficient electric equipment for low- and moderate-income households.
The same page says the U.S. Department of Energy gave Tennessee a conditional award in January 2025, that the state must receive full approval and complete contracting before launch, and that households cannot yet access these rebates. It also warns residents about offers claiming to be part of the programs before they open.
Tennessee counties by owner-occupied homes
The ten counties with the most owner-occupied homes, with the share of those homes heated by utility gas and by electricity, from the ACS 5-year 2020-2024 county tables B25003 and B25117. The table is a housing profile and makes no statement about where leads come from.
| County | Owner-occupied homes | Heated by utility gas | Heated by electricity | Source |
|---|---|---|---|---|
| Shelby | 196,379 | 58.4% | 39.8% | ACS 2020-2024, B25003 and B25117 (county) |
| Davidson | 171,526 | 44.8% | 52.8% | ACS 2020-2024, B25003 and B25117 (county) |
| Knox | 131,117 | 42.8% | 54.1% | ACS 2020-2024, B25003 and B25117 (county) |
| Hamilton | 98,531 | 38.9% | 58.1% | ACS 2020-2024, B25003 and B25117 (county) |
| Rutherford | 83,895 | 30.5% | 65.9% | ACS 2020-2024, B25003 and B25117 (county) |
| Williamson | 72,671 | 61.7% | 34.4% | ACS 2020-2024, B25003 and B25117 (county) |
| Sumner | 56,545 | 48.4% | 46.9% | ACS 2020-2024, B25003 and B25117 (county) |
| Montgomery | 54,302 | 24.2% | 71.5% | ACS 2020-2024, B25003 and B25117 (county) |
| Sullivan | 49,708 | 11.3% | 84.2% | ACS 2020-2024, B25003 and B25117 (county) |
| Wilson | 45,547 | 40.2% | 54.9% | ACS 2020-2024, B25003 and B25117 (county) |
Only two of the ten lean toward gas: Williamson, at 61.7% utility gas, and Shelby, home to Memphis, at 58.4%. At the other end, Sullivan in the northeast corner heats 84.2% of its owner homes with electricity, in the same county data (2020-2024 ACS).
Reading the Tennessee numbers for HVAC coverage
Three points follow from the Tennessee data for a buyer deciding where and what to cover:
- Electric systems lead. 56.7% of owner homes on electricity in the 2020-2024 ACS means heat pump and electric furnace work covers more than half of Tennessee owner housing.
- Both seasons count. 3,549 heating and 1,571 cooling degree days in 2025 in the NCEI series put real load on both the heating and the cooling side of a system.
- Gas clusters in two counties. Shelby and Williamson are the only top-ten counties where gas leads, so a buyer with gas furnace crews has a narrower Tennessee map than one that services heat pumps.
The points describe climate and housing only, using the official sources linked above, and say nothing about the number or location of Tennessee HVAC requests.
What Tennessee HVAC buyers filter on
Tennessee HVAC buyers filterFilterA rule that decides which leads a buyer is offered, based on fields such as vertical, sub-type, state, ZIP code, homeownership or accident details. Glossary on the same kinds of fields as other home services buyers. In Tennessee they line up with the facts above like this:
- Project type: for example install, replace or repair, for heating or cooling. A heat pump replacement touches both, which is common in an electric-heat state.
- Homeowner status: about two in three Tennessee households own their home and decide on a new system.
- Timeframe: a no-heat or no-cooling call now, or a replacement the owner is still pricing.
- ZIP code: for example the gas-heated Memphis and Franklin areas versus the electric northeast.
When HVAC opens, Tennessee buyers will set these filters per campaign, down to the ZIP code, as on Summit’s other home services leads. Once HVAC opens, HVAC leads will be exclusive by default, with shared delivery on request. See the complete field list on the sample HVAC lead.
Where buyers filter in Tennessee
Most Tennessee HVAC contractors cover the ZIP codes within driving range of one metro area. The Census Bureau’s July 1, 2025 estimates rank these six largest; five of them cross a state line, so their figures are for the whole metro area. Once HVAC opens, buyers will be able to set coverage on any ZIP code, inside these areas or outside them.
- Nashville-Davidson--Murfreesboro--Franklin: 2,197,416 (July 1, 2025 estimate)
- Memphis, TN-MS-AR: 1,341,412 (July 1, 2025 estimate, whole metro area)
- Knoxville: 968,137 (July 1, 2025 estimate)
- Chattanooga, TN-GA: 594,530 (July 1, 2025 estimate, whole metro area)
- Clarksville, TN-KY: 349,001 (July 1, 2025 estimate, whole metro area)
- Kingsport-Bristol, TN-VA: 314,834 (July 1, 2025 estimate, whole metro area)
