Compare Local Knoxville Estimates →Census measures use Knoxville city, Tennessee (incorporated place; GEOID 1600000US4740000) as a statistical proxy for Knoxville. This is not a NumeralQ service boundary.

Annual sums of NOAA/NCEI 1991–2020 monthly base-65°F normals at KNOXVILLE MCGHEE TYSON AP, TN US (station USW00013891). This is station-point context, not a value for every address.
23.7% utility gas 74.9% electricity
Shares of occupied housing units in Knoxville city, Tennessee reporting each as their primary heating fuel, not equipment or address-level service.
58.9% built before 1980
A descriptive estimate for housing units in the accepted Census geography; it does not identify HVAC system characteristics.
52.3% one-unit detached
A descriptive share of housing units in the accepted Census geography, not a measure of equipment or installation conditions.
NOAA station record: KNOXVILLE MCGHEE TYSON AP, TN US (USW00013891); 35.8181, -83.9858; elevation 293.2 m. Station-to-routing-point distance: 3.685 km. Nearest station, by Haversine distance to project routing point, among NOAA 1991-2020 monthly-normal station files with complete HDD65 and CDD65 for months 01-12; tie-break by station ID.
HDD65 and CDD65 are annual sums of 12 monthly base-65°F values from the 1991-2020 normals. They describe the station point, not a market average.
Accepted Census geography: Knoxville city, Tennessee; incorporated place; GEOID 1600000US4740000; ACS 2024 5-year (2020-2024).
ACS percentages are derived point estimates. No ratio MOE is calculated for the derived shares; the published category estimate/MOE and denominator are shown above.
B25034’s aggregate MOE is an approximation from component MOEs, not a separately published table value.
Scope: NOAA HDD65/CDD65 is one station-based climate evidence family; the Census tables form one ACS evidence family. ACS values describe reported housing-unit measures for the named statistical geography, not an individual property.
Overall project costs in Knoxville run roughly 6% below NumeralQ's national planning baseline, giving local homeowners a cost advantage versus major metro markets.
| System Type | Installed Cost (Knoxville) | Lifespan |
|---|---|---|
| Central A/C Unit Only | $3,290 – $7,050 | 15–20 years |
| Gas Furnace + A/C Split System | $6,580 – $14,100 | 15–25 years |
| Heat Pump System (full) | $7,520 – $16,920 | 15–20 years |
NumeralQ applies a city multiplier to its national planning baseline; it does not use live Knoxville labor-rate data. Get itemized quotes from licensed local contractors for project-specific accuracy.
Model midpoints for a typical project size use the city multiplier applied to the national planning baseline. They are not contractor quotes.
In Knoxville, TN, the typical hvac replacement cost project costs $6,580–$14,100 (typical project range). With a humid with mountain-influenced weather climate, Knoxville is below the national average, making it one of the more competitive markets in the region.
Our estimates apply a national planning baseline adjusted by a city-specific market multiplier — producing a local cost range for typical project scope. Not crowdsourced averages.
In Knoxville, the typical hvac replacement project runs $6,580–$14,100 (typical project range). Knoxville prices are below the national average, offering competitive value in the local market. Get at least 3 itemized written bids — pricing variation between contractors for identical scope typically ranges 20–40% in any local market.
Compare the home’s load, available fuel, and equipment documentation, equipment documentation, and the full installation scope. Actual energy use and costs depend on the property, selected equipment, usage, and utility terms; this page does not forecast household bills.
Tennessee requires a Home Improvement License (HIC) for projects over $3,000 in value involving residential remodeling or construction. Confirm active general liability insurance (minimum $1M) and workers' compensation coverage. Get written proof of both before work starts.
Refrigerant regulation changes (R-22 phase-out, R-410A transition) added $300–$800 to average system costs in 2024–2026. Systems using R-32 or R-454B are the new standard.
