Annual sums of NOAA/NCEI 1991–2020 monthly base-65°F normals at BIRMINGHAM AP, AL US (station USW00013876). This is station-point context, not a value for every address.
43.2% utility gas 54.3% electricity
Shares of occupied housing units in Birmingham city, Alabama reporting each as their primary heating fuel, not equipment or address-level service.
71.6% built before 1980
A descriptive estimate for housing units in the accepted Census geography; it does not identify HVAC system characteristics.
58.0% 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: BIRMINGHAM AP, AL US (USW00013876); 33.5656, -86.745; elevation 187.5 m. Station-to-routing-point distance: 8.003 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: Birmingham city, Alabama; incorporated place; GEOID 1600000US0107000; 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 Birmingham are approximately 9% below NumeralQ's national planning baseline — one of the more affordable markets in the region.
| System Type | Installed Cost (Birmingham) | Lifespan |
|---|---|---|
| Central A/C Unit Only | $3,185 – $6,825 | 15–20 years |
| Gas Furnace + A/C Split System | $6,370 – $13,650 | 15–25 years |
| Heat Pump System (full) | $7,280 – $16,380 | 15–20 years |
NumeralQ applies a city multiplier to its national planning baseline; it does not use live Birmingham 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 Birmingham, AL, the typical hvac replacement cost project costs $6,370–$13,650 (typical project range). With a humid subtropical climate, Birmingham is significantly 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 Birmingham, the typical hvac replacement project runs $6,370–$13,650 (typical project range). Birmingham prices are significantly 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 cooling load and humidity-control needs, 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.
Alabama requires general contractors to be licensed by the Alabama Licensing Board for General Contractors (ALBGC) for projects over $50,000. 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.
