Heat Pump Payback in Round Lake Beach, IL
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. $5,500 is what Round Lake Beach would pay extra to go electric rather than replace the furnace and AC with the same again. 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 low of -11°F in the 2024 station record. 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 yearly running costs in 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 the current furnace-and-AC running cost near $816 a year, against 19.06¢ per kWh for electricity. With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $9,540 behind.
The break-even point in Round Lake Beach
The heat pump would become the cheaper option in Round Lake Beach if electricity fell to 13.3¢/kWh (from 19.06¢) or gas rose above $16.11 per Mcf (from $11.25). At today's prices a cheaper quote cannot rescue the gas comparison in Round Lake Beach, since there is no yearly saving to recover it from.
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 6-year payback clears the $10,000 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.
