How we got these numbers
National benchmark costs from RSMeans, Angi, Fixr, and HomeGuide are adjusted for Minnesota 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. Minnesota's RPP is 1.0 (national baseline = 100) and its BLS labor adjustment factor is 1.04. 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(Minnesota) = 1.0 · BLS adj = 1.04

COMMON MISTAKE
Oversizing short-cycles the system and wastes money.
- 2
Recover the old refrigerant legally and disconnect power and gas.
- 3
Set the new condenser and furnace and connect the line set.
- 4
Pull a vacuum, charge the refrigerant, and verify the gas and electrical connections.
