Should Round Lake Beach switch to a heat pump?
Here in Round Lake Beach, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Round Lake Beach would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Running costs here land $269 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Round Lake Beach's numbers say wait.
The climate behind Round Lake Beach's payback figure
Degree days tell the story here: Round Lake Beach racks up 5324 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 777 cooling degree days on the cooling side. -0.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -11°F on file. Worked through the model, that's a seasonal COP of 2.68 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Round Lake Beach — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The month-to-month numbers for Round Lake Beach
Electricity use for heating alone comes out to about 5,030 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,085 a year. Round Lake Beach's gas rate of 11.25 per Mcf, applied to the 55 Mcf a year the furnace burns, puts its running cost near $816 a year, against 19.06¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $7,540 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Round Lake Beach heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $1,676 a year comes back this way, enough that the 4.8-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Round Lake Beach ranks in this dataset
Ranked against the other 3206 cities covered, Round Lake Beach comes in at 465 for heating severity — 1 would be the coldest place in the dataset — and 1469 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Round Lake Beach's 2.68 seasonal COP and payback figure. Round Lake Beach's -0.9°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
