What the numbers say about ductless mini-split in Iowa
Iowa logged 5,491 population-weighted heating degree-days over October–March (NOAA CPC state series), 157% of the CONUS figure of 3,500, which is why this page runs ductless mini-split 14.7 hours a day against the national 9.4 — 5.3 hours more. At Iowa’s October 2025–March 2026 average rate of 13.1¢/kWh that makes it the 16th most expensive of the 20 cold states for ductless mini-split: $703 for the 182-day winter, against Nebraska’s $552 and Maine’s $1,886. MidAmerican Energy Co, Iowa’s largest utility with 632,436 residential customers, averages 11.0¢ — $590 for the same hours — while Adjustment 2024 at 13.0¢ comes to $698, a $107 spread on identical use. Per million Btu delivered, this unit at the NEEP median COP of 2.17 costs $17.69 against $10.84 for natural gas at Iowa’s winter average of $1.03/therm, which is the whole-house comparison the Iowa heating page works through. Iowa’s winter-average rate (13.1¢) sits 2.89¢ below its July 2026 reading of 15.99¢; the season figure uses the winter average because that is when ductless mini-split runs.

How we calculated this
Worked for ductless mini-split in Iowa: 2,000 W ÷ 1,000 × 0.1310 $/kWh = $0.26 per hour; hours per day = 9.4 × (5,491 ÷ 3,500) = 14.7; 2,000 ÷ 1,000 × 14.7 × 182 × 0.1310 = $703 for the winter. Rate: EIA Electric Power Monthly 5.6.A (October 2025–March 2026 average); degree-days: NOAA CPC state population-weighted HDD, October 2025–March 2026, against the CONUS total; utility prices: EIA-861 2024.Sources: U.S. Energy Information Administration (EIA) electricity rates · DSIRE incentive records · public IRS/OBBBA guidance.
