Geothermal Heating and Cooling Installation in Michigan

Efficient Heating and Cooling With Geothermal Systems

Geothermal systems provide year-round heating and cooling by transferring heat between your home and the ground below the surface. Because underground temperatures remain relatively stable throughout the year, geothermal heat pumps can deliver reliable comfort even during Michigan winters. Dunham Service provides geothermal heat pump installation Michigan homeowners explore when they want long-term efficiency and dependable heating and cooling. As a Michigan Mechanical Contractor with EPA certification, the company installs and services geothermal systems for homes throughout Nashville, Hastings, Charlotte, and surrounding Barry County communities.

How Geothermal Heating and Cooling Works

Geothermal systems use underground piping called a loop system to transfer heat between the home and the earth.

Frequent Cooling Repairs

Winter Heating

During winter, the geothermal heat pump extracts heat from the ground and transfers it into the home.

Summer Cooling

In summer, the process reverses and heat from the home is transferred into the ground.

Stable Underground Temperatures

Because underground temperatures remain consistent year-round, geothermal systems can operate efficiently across Michigan’s seasonal climate.

This approach allows geothermal systems to provide both heating and cooling using the same equipment.

Types of Geothermal Loop Systems

Different geothermal installations use different loop configurations depending on property size, soil conditions, and available space.

• Horizontal Loop Systems
  Horizontal loops are installed in trenches across the property and are commonly used when land area is available.
• Vertical Loop Systems
  Vertical loops are drilled deep underground and are often used when property space is limited.
• Closed Loop Systems
  Closed loops circulate fluid through underground piping to transfer heat.

Selecting the right loop configuration depends on site conditions and system design requirements.

Is Your Property a Good Fit for Geothermal?

Several factors determine whether geothermal installation is suitable for a home.

Available Yard Space

Some installations require adequate space for trenching or drilling.

Soil and Ground Conditions

Local soil composition and groundwater conditions influence loop system design.

Existing HVAC Infrastructure

Geothermal heat pumps typically integrate with existing duct systems or hydronic heating setups.

A site evaluation helps determine whether geothermal installation is feasible for the property.

Geothermal systems still require routine HVAC maintenance to operate efficiently over time. Dunham Service provides geothermal service and repair for homeowners who want ongoing support after installation. Routine service helps maintain system performance and identify developing issues before they impact heating or cooling reliability.



Typical geothermal maintenance includes:

• Inspecting the geothermal heat pump
  
• Checking system pressures and circulation
  
• Verifying airflow and system performance
  
• Inspecting electrical components and controls

Installing a geothermal heating and cooling system involves several stages that help ensure the system is designed and installed properly.
