What the numbers say about ductless mini-split in Michigan
Michigan logged 5,791 population-weighted heating degree-days over October–March (NOAA CPC state series), 165% of the CONUS figure of 3,500, which is why this page runs ductless mini-split 15.6 hours a day against the national 9.4 — 6.2 hours more. At Michigan’s October 2025–March 2026 average rate of 20.11¢/kWh that makes it the 7th most expensive of the 20 cold states for ductless mini-split: $1,138 for the 182-day winter, against Nebraska’s $552 and Maine’s $1,886. DTE Electric Company, Michigan’s largest utility with 2,067,779 residential customers, averages 20.1¢ — $1,138 for the same hours — while Great Lakes Energy Coop at 19.2¢ comes to $1,087, a $51 spread on identical use. Per million Btu delivered, this unit at the NEEP median COP of 2.17 costs $27.16 against $11.05 for natural gas at Michigan’s winter average of $1.05/therm, which is the whole-house comparison the Michigan heating page works through. Michigan’s winter-average rate (20.11¢) sits 2.94¢ below its July 2026 reading of 23.05¢; 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 Michigan: 2,000 W ÷ 1,000 × 0.2011 $/kWh = $0.40 per hour; hours per day = 9.4 × (5,791 ÷ 3,500) = 15.6; 2,000 ÷ 1,000 × 15.6 × 182 × 0.2011 = $1,138 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.
