      Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.

      Questions4
      Do heat pumps work in Rockford winters?
      Rockford averages 12 nights a year at or below 0°F, so pick a cold-climate certified model and check its output at 5°F. The average winter low is 18°F, and the heating season adds up to 6,497 heating degree days (NOAA 1991-2020 normals).
      How much does it cost to run a heat pump in Rockford?
      A typical 3-ton central heat pump (17.0 SEER2, 9.0 HSPF2) uses about $1,974 of electricity a year for heating and $241 for cooling in Rockford, at the Illinois average of 19.0¢/kWh. The most efficient models cost less - see the rankings above.
      Is a heat pump cheaper than a gas furnace in Rockford?
      Not on heating alone at today's prices: about $1,974 a year with a typical heat pump versus $1,064 with a 95% gas furnace (Illinois averages: 19.0¢/kWh, $1.08/therm). A high-HSPF2 model narrows the gap, and a heat pump also replaces the air conditioner. Against propane, oil or electric heat it is usually far cheaper.
      What size heat pump do I need for a 2,000 sq ft house in Rockford?
      With average insulation, roughly a 5-ton system: the estimated cooling load is 27,600 BTU/h and the heating load 54,000 BTU/h. Use the size calculator for your own house, and ask installers for a Manual J calculation.
