How we got these numbers
National benchmark costs from RSMeans, Angi, Fixr, and HomeGuide are adjusted for Alabama using two federal datasets: the Bureau of Economic Analysis Regional Price Parity (RPP) index and the Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics. Alabama's RPP is 0.9 (national baseline = 100) and its BLS labor adjustment factor is 0.87. Higher RPP means goods and services cost more relative to the national average; the BLS factor scales contractor labor rates to local wage levels. We blend these two adjustments, weighted 40% RPP, 60% BLS labor, to produce the ranges shown above.
adjusted_cost = national_benchmark × (0.4 × RPP/100 + 0.6 × bls_labor_adj)
RPP(Alabama) = 0.9 · BLS adj = 0.87

Build sequence
- 1
Size the system to the home with a load calculation.
COMMON MISTAKE
An oversized unit short-cycles and wastes the efficiency you paid for.
- 2
Set the outdoor unit on a level pad and mount the indoor coil or air handler.
- 3
Run and connect the refrigerant lines, then evacuate and charge the system.
COMMON MISTAKE
Refrigerant handling requires EPA certification and is the main reason this is a pro job.
- 4
Make the electrical connections and install the thermostat.
- 5
Commission, test heating and cooling, and verify the charge and airflow.
