Geothermal or Ground Source Heat Pumps

Geothermal or ground-source heat pumps (GSHPs) are energy-efficient systems that use the stable temperature of the earth to heat and cool buildings.

What is Geothermal?

Geothermal (or ground-source) heat pumps use the steady temperature underground to keep your home comfortable year-round. Instead of burning fuel, they move heat—drawing warmth from the ground in the winter and sending excess heat back underground in the summer. The result is an incredibly efficient, reliable system that works in every season.

Benefits of Geothermal for Homes

#1 Year-round Comfort

Cozy in winter, cool in summer.

#2 Ultra-efficient

Uses stable ground temperatures, often more efficient than air-source systems.

#3 Lower Environmental Impact

Runs on electricity, slashing your carbon footprint.

#4 Potential Energy Savings

May reduce heating and cooling costs over time.

#5 Quiet and Low-maintenance

No noisy outdoor unit and minimal upkeep.

#6 Long Lifespan

Underground piping can last 50+ years with proper installation.

Is Geothermal Right for Your Home?

Not every property is a perfect fit, but many are! Factors to consider include:

Land/yard space

You’ll need enough room for the underground piping loops (vertical or horizontal).

Soil and geology

Ground conditions affect installation feasibility and cost.

Existing system

Geothermal can sometimes integrate with your current ductwork or radiant heating system.

Budget & incentives

While the upfront cost is higher, tax credits, rebates, and long-term savings can make it worthwhile.

A qualified installer can evaluate your property and help you decide if geothermal is the right solution for your home.

Homeowners switching to heat pumps from inefficient systems that run on fuel oil, propane, or traditional electric resistance can save close to $1,000 per year.
