Is Geothermal Heating and Cooling Right for Your New Jersey Home?

👤 Robbins Team 📅 February 2, 2026

Energy bills across New Jersey keep climbing higher and higher. Homeowners are exploring geothermal heating and cooling as a way to slash costs while staying comfortable year-round. But is it the right choice for your home?

Since 1910, Robbins Water Service has helped South and Central New Jersey homeowners make smart decisions about heating, cooling, and water systems. As licensed Master Well Drillers with over a century of local experience in Burlington County, Atlantic County, Gloucester County, and many more, we know what works and what doesn't.

This guide answers your most important questions about geothermal systems, from how they work to what they cost.

🎯 Key Takeaways

  • Energy Savings: 30-60% lower bills vs. traditional systems
  • Cost: $30,000-$60,000 total installation
  • Payback: 5-10 years through energy savings
  • Lifespan: 50+ years for loops, 20-25 for heat pump
  • Best For: Homeowners staying 5-10+ years

What Is Geothermal Heating and Cooling?

Geothermal systems use the earth's constant 50-60°F underground temperature to heat and cool buildings efficiently. Underground pipes circulate fluid that absorbs heat from the ground in winter or deposits heat into the ground in summer.

Here's the simple version: Instead of creating heat by burning fuel or fighting extreme outdoor temperatures, geothermal moves existing heat to where you need it. This transfer process uses far less energy than conventional heating and cooling.

When we drill wells and install loop systems of underground piping. We use a water-based solution that is circulated continuously through the piping. Absorbing warmth in winter, and depositing heat in summer. A heat pump inside your building then distributes the conditioned air throughout your space.

What Are the Types of Geothermal Systems?

There are two main types: closed-loop and open-loop systems.

Closed-Loop Systems (most common for new residential installs):
A sealed network of pipes circulates a water-antifreeze mixture continuously. Closed-loop can be installed vertically (drilled deep) requiring less room then horizontal systems (trenched across your property).

Open-Loop Systems:
Pumps groundwater from a well, extracts thermal energy, then returns water to the aquifer through a return well. Highly efficient with adequate, clean groundwater.

Which system works best depends on your lot size, soil conditions, water table, and local regulations. With 114 years of drilling experience in South Jersey geology, we can evaluate your property and recommend the right approach.

What Are the Benefits of Geothermal?

  1. Energy savings of 30-60% vs. traditional oil, propane, or electric systems
  2. Exceptional lifespan: underground loops last 50+ years, heat pumps 20-25 years
  3. One system handles both heating and cooling year-round
  4. Minimal maintenance with fewer mechanical components
  5. Quiet operation with equipment mostly underground
  6. Zero direct emissions and improved indoor air quality
  7. Lower long-term costs despite higher upfront investment

For New Jersey homeowners, that 30-60% savings often translates to $1,500-$3,000+ in annual energy bill reductions. The system moves heat rather than creating it, requiring just 1 unit of electricity to move 3-4 units of heat energy.

How Much Does Geothermal Cost in New Jersey?

Total installation: $30,000-$60,000 for an average sized residential system (drilling, equipment, installation).

The good news: Most homeowners recoup this investment in 5-10 years through energy savings.

Cost Factors:

  • System size (based on your heating/cooling needs)
  • Loop type (vertical, horizontal, or open-loop)
  • Soil and geological conditions
  • Property space available for drilling
  • Existing ductwork condition

Return on investment: With $1,500-$3,000 annual savings depending on sizing of the location, payback typically occurs within 5-10 years. After that, you enjoy lower energy bills for decades.

How Long Does Installation Take?

Timeline: 1-2 weeks total

  • 3-5 days for drilling and loop installation
  • 1-2 days for heat pump installation and connection

New construction is typically faster than retrofits. Our modern equipment and experienced team work efficiently to deliver fast, high-quality results.

How Long Do Geothermal Systems Last?

Underground loops: 50+ years
Heat pump: 20-25 years

This far exceeds traditional furnaces and AC units (15-year average). The underground piping is virtually maintenance-free. You may replace your heat pump once or twice in your lifetime, but the loop could serve your home for half a century or more.

What Should You Consider Before Installing?

Key considerations:

  • Higher upfront cost (offset by tax credits and long-term savings)
  • Adequate property space for drilling or trenching
  • 5-10 year stay in your home to see full ROI
  • Experienced contractor with both drilling and geothermal expertise

Property requirements vary by system type. Vertical systems need less surface area but must be drill 150-400 feet deep. Horizontal systems need a lot more yard space but don't need to be drilled. Our South Jersey expertise helps us assess your property honestly and recommend the best system for your situation.

Is Geothermal Worth It?

Yes, if you:

  • Plan to stay in your home 5-10+ years
  • Currently heat with expensive oil, propane, or electric
  • Are you building new or replacing an aging HVAC system
  • Have adequate property space
  • Value long-term savings over lower upfront cost

With 30-60% energy savings and a 50+ year lifespan, most homeowners see positive ROI within a decade. The combination of occasional federal tax credits, energy savings, and minimal maintenance makes geothermal one of the smartest long-term home investments.
