Ten Summers of Cooling Bills in Laramie
At $0.169 per kWh, about 22% below the national average of $0.217, Wyoming electricity sets how fast efficiency pays for itself. A 1.62% yearly rise in Wyoming electric rates, the decade trend, is built into every ten-year number on this page.
Hover or tap any year to see what each rating costs to run that season. Rates rise 1.62% a year, the WY ten-year trend.
2026 = this season at WY's current rate. Each later year compounds the historic 1.62%/yr rise; costs rounded up to $10.
At that rate, a 16 SEER system in Laramie uses about 2,802 kWh a season, roughly $480 a year; a worn 9 SEER unit would cost about $840.
Upgrade Payback Finder: Your Old AC vs a New One
Pick the unit you have and the one you are considering. Figures are for a 3.5-ton system at Wyoming electric rates ($0.169/kWh, rising 1.62% a year).
| Installed price of the new system | $8,210 |
| Electricity saved, first year | $310 |
| Saved over 10 summers (rates rising) | $3,280 |
| Payback | 22.6 years |
| Net after 10 summers | -$4,940 |
Savings alone fall short: 9 to 14 SEER is still $4,940 behind after 10 summers in WY.
If the old unit still works, the full install price is the cost of the upgrade. If it has to be replaced anyway, compare the extra price over a 14 SEER bid with the extra savings.
Leaving a 9 SEER Unit Behind in Laramie

Matching the System to Laramie Weather
The sizing for Laramie (about 41.3° N) uses Wyoming averages: climate region 1, summer afternoons near 84°F, winter lows near 11°F. Winter is the long season in Laramie. The AC works a few warm months, while the heating side runs for most of the year.
Climate zones run from 1 (cool) to 5 (hot); Wyoming is in Zone 1.
Dry air in Laramie means nearly all of the AC's capacity goes into lowering the temperature.
Cheyenne is the nearest guide city to Laramie, roughly 45 miles to the east.
When both the furnace and the AC in a Laramie home are near the end, doing them in one visit saves a second labor charge. Treat 42,000 BTU as the starting estimate. Insulation, window area, shade and air leaks can move the right size either way, which is what a Manual J load calculation measures.
Ductwork and Space in a Laramie Install
No ducts in your Laramie home? Ductless mini-splits add cooling without opening walls and ceilings. Short drives and simple access help explain why Laramie prices sit at or below the Wyoming average.
For one finished attic or an addition, a single-zone mini-split usually costs less than extending the ducts.
Picking the Right Month in Laramie
Furnace calls fill Laramie schedules all winter, so late spring and early fall suit cooling work best. A permit and inspection document that the Laramie install meets code, which helps when the house is sold.

Quick Answers
Figures below use Wyoming averages; energy prices as of October 2026.
Does a heat pump heat for less than natural gas in Wyoming?
No, natural gas still wins in Wyoming: 72,342 BTUs per dollar against 60,535 for a heat pump at COP 3. The break-even power price is about 14.2¢ per kWh, and the Wyoming average is 16.9¢. A more efficient heat pump narrows the gap.
Is electricity in Wyoming expensive compared with other states?
Wyoming pays 16.9¢ per kWh on average: 22% under the national figure of 21.7¢ and the 14th cheapest of 51. Cooling bills rise and fall with it.
Is a cold-climate heat pump needed in Wyoming?
Yes, plan on one. Winter lows in Wyoming average about 11°F statewide, where a standard heat pump loses much of its output. Cold-climate models keep heating below zero; size for the coldest nights.
What does a heat pump save over electric baseboard in Wyoming?
Roughly two-thirds of the bill at COP 3. With the Wyoming average at 16.9¢ per kWh, baseboard heat costs about $49.56 per million BTU and a heat pump about $16.52.
What is the best season to replace an AC or furnace in Wyoming?
The shoulder seasons, spring and fall, ahead of need. Winter lows near 11°F statewide mean heating work should wrap up by early fall. Crews are busiest in the first hot week and the first freeze, and a forced emergency swap leaves no time to compare bids.
Is it smart to replace the furnace and AC together?
When both are aging, generally yes: one visit, one labor charge, and a matched coil and condenser, which the efficiency rating assumes. If one is fairly new, price each job on its own.
