Why Wisconsin’s Climate Favors Geothermal Systems

Burlington winters are hard on conventional equipment. Outdoor air temperatures can drop well below 0°F. These conditions cause air-source heat pumps to lose efficiency rapidly as they work against the cold. Geothermal systems sidestep that problem entirely. A few feet below the frost line, ground temperatures in southern Wisconsin remain stable in the low-to-mid-50s°F year-round, regardless of what’s happening above the surface.

That thermal stability is what makes ground-source systems a strong match for this climate. In heating mode, the system draws warmth from the earth rather than frigid outdoor air. In summer, the process reverses. Heat extracted from your home dissipates into the cooler ground, providing efficient cooling even during humid Wisconsin summers. The result is consistent performance through seasonal extremes that challenge other system types.

How a Geothermal System Works

A geothermal system has two main components: a ground loop and an indoor heat pump. The ground loop is a network of buried pipes filled with a water-based solution that circulates continuously, picking up heat from the earth in winter or releasing it in summer. That fluid carries thermal energy to the indoor heat pump, which transfers it into your home’s distribution system.

Because the system moves heat rather than generating it through combustion or electric resistance, geothermal heat pumps can deliver more usable energy than the electricity they consume. This ratio is measured as the coefficient of performance (COP). A single geothermal system can replace both a furnace and a central air conditioner, handling year-round comfort from one integrated unit.

Geothermal System Types We Install

Not every property calls for the same loop configuration. H.J. Faust, Inc. installs the full range of geothermal system types, and the right choice depends on your lot, soil, and proximity to water.

• Horizontal Loop: Pipes laid in trenches, common for residential properties with adequate yard space
• Vertical Loop: Pipes drilled deep into the ground, suited for lots with limited surface area
• Pond or Lake Loop: A coiled closed loop placed at the bottom of a qualifying water body
• Geothermal Radiant: Pairs the ground-source heat pump with in-floor radiant heating for even, low-temperature distribution

In Wisconsin, this work must be performed by a licensed heat exchange driller. Lot size, topography, soil conditions, and proximity to water all shape which loop type fits a given property.

Is Geothermal Right for Your Burlington Property?

Geothermal systems tend to offer the strongest return for property owners planning to stay long term. Higher upfront installation costs are offset by lower operating expenses over a system life that can span several decades. Properties with existing ductwork are often straightforward candidates for geothermal integration. Homes without it may require modifications or alternative distribution approaches.

We start every evaluation with a thorough inspection before making any recommendation, and we won’t suggest more than your property actually needs. Our team can assess your lot size, soil type, topography, existing HVAC infrastructure, and heating and cooling load before recommending a system type. As a design-build contractor, we handle new construction, full replacements, and system upgrades as part of our end-to-end HVAC capability.

Our Geothermal Services in Burlington

We cover the full geothermal lifecycle, from initial design through long-term maintenance. Our team handles system design and installation, heat pump replacement and upgrades (including controls and thermostat modernization), and repairs for existing geothermal equipment, including short cycling, circulation issues, uneven temperatures, and control problems.

What sets our technicians apart is training depth. Every mechanic comes up through our structured Internal Apprenticeship & Development Program, a multi-year curriculum pairing classroom instruction with hands-on fieldwork under direct senior mechanic supervision. Beyond that foundation, every field and office employee attends a minimum of four training sessions per year. We also service all major HVAC brands alongside Lennox systems, so if you have an existing geothermal unit from another manufacturer, we can work on it. If something goes wrong at 2 a.m. in January, our 24/7 emergency service means you’re not left waiting.

Annual Maintenance for Geothermal Owners

We recommend one spring check-up and one fall check-up each year for geothermal systems. Our Annual Maintenance Agreement formalizes that schedule and adds meaningful value: a 30-point inspection, both a furnace check-up and an air conditioner check-up, priority scheduling, no overtime charges for after-hours calls, and a 10% discount on all parts and labor when repairs are needed.

Wisconsin Incentives for Geothermal Systems

Several savings opportunities may be available to Burlington homeowners installing a geothermal system in 2026. Eligibility and amounts are subject to change, so verify current terms before making decisions.

Focus on Energy: Wisconsin’s Focus on Energy program currently offers a geothermal heat pump rebate of $1,000 for customers with natural gas service or $750 without. Applications must be submitted within 60 days of installation and no later than August 31, 2026. Burlington homeowners served by We Energies apply through Focus on Energy directly.

HEAR Program: The Wisconsin Home Electrification and Appliance Rebates (HEAR) program may provide up to $8,000 for qualifying households below 150% of area median income. HEAR rebates can be stacked with Focus on Energy rebates, which may meaningfully reduce the net installation cost for eligible homeowners.

Our Geothermal HVAC Service Area

We provide geothermal HVAC services throughout Burlington and the surrounding region, including Waterford, WI, Lake Geneva, WI, and communities across Walworth County, Racine County, and Kenosha County.

FAQs on Geothermal HVAC Systems

How Does Geothermal Compare to an Air-Source Heat Pump in Wisconsin Winters?

Air-source heat pumps lose efficiency as outdoor temperatures drop. That's a real limitation in Burlington winters that can push well below 0°F. Geothermal heat pumps draw from stable ground temperatures rather than outdoor air, so their performance isn’t affected the same way by extreme cold. For Wisconsin homeowners, that consistency is one of the primary reasons to choose geothermal over air-source.

Is Installation Disruptive to My Yard?

Ground loop installation does require excavation or drilling, but the disruption is temporary. We restore the landscape to its original condition as much as possible after work is complete. Vertical loop systems involve the smallest surface footprint. Horizontal systems require more open yard area but are typically the more cost-effective option where space allows.

How Long Does a Geothermal System Last?

Indoor heat pump components typically last 20 to 25 years with proper maintenance. The underground ground loops are significantly more durable. They can last 50 years or more. That longevity makes geothermal a strong long-term investment for homeowners planning to stay in their property.

How Much Does Geothermal Cost in Burlington?

Geothermal installation costs vary based on system type, loop configuration, soil and property conditions, and home size. There’s no single number that applies to every situation, which is why a site-specific assessment matters. Higher upfront costs are typically offset over time by lower operating expenses compared to conventional heating and cooling. Contact us for a free, no-obligation quote.

Can I Replace My Central AC with a Geothermal System?

Yes. A geothermal system handles both heating and cooling, so it can replace your central air conditioner and your furnace in a single installation. If your home already has ductwork, integration is often straightforward. We can assess your existing infrastructure during the consultation to identify the most efficient path forward.
