The Investment Case
More Than HVAC — It's Infrastructure
Geothermal creates a generational legacy. Future inhabitants enjoy low-cost, sustainable comfort for decades — and your home's value reflects it.
$15K–$30K
Added Home Value
Homes with geothermal systems command a premium. The "green halo" attracts buyers looking for lower operating costs and modern infrastructure.
50–100 yrs
Built to Last Generations
The ground loop is permanent infrastructure with a 50–100 year lifespan. It stays in place for generations, so future heat pump replacements cost less — and it appreciates as labor, drilling, and material costs rise.
Hedged
Against Gas Spikes
Natural gas prices can spike — electricity is steadier. Going all-electric with geothermal removes your exposure to fossil fuel price swings.
20–25 yrs
Heat Pump Life
Twice the lifespan of conventional furnaces. And when it's time to replace, costs are dramatically lower — the ground loop stays in place.
Geothermal doesn’t burn anything to make heat. It moves heat the ground already has.
That is why one unit of electricity comes back to you as three to six units of heating — and why the ground keeps delivering it on the coldest day of the year, when outdoor air has the least heat left to give.

Typical ranges for Chicago-area conditions. Your result depends on your building, your loop and your equipment.
Total Cost of Ownership
Cheaper to Own, Year After Year
Sticker price isn't the whole story. When you account for energy savings, fewer repairs, and longer lifespans, geothermal is the lowest total-cost-of-ownership HVAC choice for a Chicago home.
Lower Monthly Bills, For Decades
Energy savings of up to 70% compound year after year. Combined with ComEd's Space Heating rate, total monthly utility costs drop dramatically — and stay low as gas prices climb.
Fewer Service Calls
No combustion, no outdoor condenser exposed to weather, and far fewer moving parts than a furnace + AC pairing. Less to break means less to fix.
Cheaper Replacement Cycles
Heat pumps last 20–25 years (twice a typical furnace). When replacement time comes, you only swap the indoor unit — the ground loop stays in place.
A 50–100 Year Asset
The ground loop is permanent utility infrastructure. Spread across its full lifespan, the per-year cost of comfort is lower than any conventional HVAC system.
