- Homes in City of Holly Springs's Mississippi area heat with electricity 45%, propane 26%, gas 24% (U.S. Census Bureau, American Community Survey 2019-2023). The calculator starts with propane, the most common furnace fuel here; pick yours above.
- Mississippi HVAC installer wages are 20% below the U.S. median (BLS), so installed prices are scaled by 0.90.
- Energy use for heating and cooling:
- New propane furnace + new AC: 2,183 kWh and 366 gallons of propane a year for heating and cooling
- Heat pump (replaces both): 4,487 kWh a year for heating and cooling
- High-efficiency cold-climate heat pump: 3,532 kWh a year for heating and cooling
Rebates

How City of Holly Springs's rates change the answer
City of Holly Springs's electricity price for a typical home is 18% below the Mississippi average ($0.122 vs. $0.150 per kWh). A heat pump moves your heating from gas, propane or oil to electricity, so the electricity price is the biggest single factor: calculators that use a state average can get the answer wrong for your utility. At these prices, a heat pump is cheaper to run than propane heat for a typical home here.

How we calculate this
Heating and cooling need
Your home's yearly heating and cooling need comes from 1991-2020 NOAA climate normals for the nearest weather station, scaled by floor area and insulation level. If you know last winter's gas use, compare it with the therms in the energy-use list above.
Heating fuels
Choose the fuel your furnace burns: gas, propane, heating oil or electricity. Gas uses the state's average residential price over the last five winter months; propane and heating oil use the U.S. Energy Information Administration's weekly residential prices for this heating season (state, regional or U.S. average, as available), converted by heat content (91,500 Btu per gallon of propane, 138,500 per gallon of oil). An electric furnace is priced through the same electricity rates as the heat pump. The starting fuel is the most common furnace fuel in the utility's area (U.S. Census Bureau, American Community Survey).
Equipment efficiency
New gas or propane furnace 95% AFUE, new oil furnace 85%, electric furnace 100%; new AC SEER2 13.4; standard heat pump SEER2 15.2 / HSPF2 7.8; high-efficiency cold-climate heat pump SEER2 21.5 / HSPF2 10.6. Heat pump efficiency falls as it gets colder, and in cold months part of the heat comes from backup electric strips (or your old furnace, if you keep it). Existing equipment is assumed to be 15-20 years old: an 80% gas or propane furnace, a 78% oil furnace or a SEER2 9.5 AC.
Installed costs
Installed prices vary a lot, so we show a typical price and a range for a home of about 1,800 sq ft with existing ductwork, scaled for larger or smaller homes: furnace and AC together $9,000–$14,000; furnace alone $3,800–$7,000; AC alone $4,500–$9,000; standard heat pump $8,000–$15,000; high-efficiency cold-climate heat pump $11,000–$20,000; electrical panel upgrade, if needed, $1,500–$4,000. These are national figures drawn from published studies and program data (NESCAUM / Energy Solutions, Heat Pumps in the Northeast and Mid-Atlantic: Costs and Market Trends (October 2024); Rewiring America, Upfront cost of home electrification (March 2024); EIA, Updated Buildings Sector Appliance and Equipment Costs and Efficiencies (2023)). The most useful number here is how much more a heat pump can cost than a like-for-like quote and still come out ahead: get quotes for both and compare.
Labor and rebates
Half of each installed price is treated as labor and scaled by the state's median HVAC installer wage relative to the U.S. median (U.S. Bureau of Labor Statistics). Listed rebates are subtracted when the box is ticked; per-ton rebates assume about one ton of capacity per 600 sq ft. Rebates change often and have eligibility rules, so confirm with the program before you buy.
Not included
Financing, maintenance (similar for all options), local town rebates, and changes in energy prices over time.
