Geothermal Heating Cost
As more homeowners in San Mateo, CA, look for energy-efficient and sustainable HVAC options, geothermal heating systems are gaining serious attention. Known for their incredible efficiency and long lifespan, geothermal systems can reduce your heating and cooling costs by up to 70%.
But one of the first questions homeowners ask is: how much does geothermal heating cost?
In this guide, we’ll break down the average cost of geothermal heating installation, the factors that influence pricing, and how long it takes to see a return on your investment.
What Is Geothermal Heating?Geothermal heating (also known as a ground-source heat pump system) uses the steady temperature of the earth to heat and cool your home.
While the air temperature in San Mateo fluctuates with the seasons, the ground temperature a few feet below the surface remains consistent year-round—around 55°F to 60°F.
A geothermal heat pump transfers heat between your home and the ground using a network of underground pipes called ground loops. In winter, it absorbs heat from the earth and moves it indoors. In summer, it reverses the process, removing heat from your home and transferring it into the ground.
This natural exchange of heat makes geothermal systems incredibly energy-efficient and environmentally friendly.
Average Cost of Geothermal Heating InstallationOn average, homeowners in California can expect to pay between $18,000 and $35,000 for a complete geothermal heating and cooling system.
Here’s a breakdown of the typical cost range by home size:
Home Size (sq. ft.) Average Cost (Installed) 1,000 – 1,500 sq. ft.$15,000 – $22,000
1,500 – 2,500 sq. ft.$22,000 – $30,000
2,500 – 4,000 sq. ft.$30,000 – $45,000While the initial cost is higher than traditional HVAC systems, geothermal heating offers long-term savings through reduced utility bills and minimal maintenance.
Factors That Affect Geothermal Heating CostSeveral factors influence how much you’ll pay for a geothermal installation:
1. Type of Ground Loop SystemThere are four main types of geothermal loops:
2. Soil and Rock ConditionsThe ease of drilling or trenching significantly impacts cost. Hard or rocky soil conditions require specialized equipment and can raise installation prices.
3. System Size and EfficiencyLarger homes need bigger geothermal systems with higher capacity heat pumps, which increase cost. However, high-efficiency geothermal units can provide greater long-term savings.
4. Ductwork ModificationsIf your home’s existing ductwork needs resizing or sealing, this can add $1,000 to $3,000 to the total project cost.
5. Incentives and RebatesThe federal clean energy tax credit offers a 30% rebate for homeowners installing a qualifying geothermal system through 2032. California may also offer local rebates through energy efficiency programs.
These incentives can significantly reduce your out-of-pocket cost—often by $5,000 to $10,000.

Factors That Affect Geothermal Heating CostSeveral factors influence how much you’ll pay for a geothermal installation:
1. Type of Ground Loop SystemThere are four main types of geothermal loops:
- Horizontal Loops – Installed in shallow trenches; less expensive but require more land.
- Vertical Loops – Ideal for smaller yards; drilled deep underground and slightly costlier.
- Pond/Lake Loops – Use a nearby water source for heat exchange (rare in urban areas).
- Open-Loop Systems – Use groundwater directly; very efficient but depend on water quality and local regulations.
2. Soil and Rock ConditionsThe ease of drilling or trenching significantly impacts cost. Hard or rocky soil conditions require specialized equipment and can raise installation prices.
3. System Size and EfficiencyLarger homes need bigger geothermal systems with higher capacity heat pumps, which increase cost. However, high-efficiency geothermal units can provide greater long-term savings.
