Geothermal Cooling Installation

Install an Energy Efficient Cooling System in Your Menomonee Falls Home


With the rising costs of oil and natural gas, homeowners are finding it more expensive to run their air conditioning systems, and welcome a cheaper central air conditioning alternative. Geothermal energy uses the earth’s natural temperature to heat and cool your home. No matter how hot the temperature is outside, the temperature below ground in Wisconsin stays consistently around 50 degrees because of the earth’s ability to absorb and retain the sun’s energy. A geothermal cooling system is able to tap into this free energy to cool your home.

How it Works

A geothermal heating and cooling system consists of 3 main parts: an underground earth loop, a heat pump, and the earth. Geothermal cooling works by using the earth’s natural temperature to extract heat from inside your home and redirect it back into an underground earth loop, or to preheat the water in your hot water tank.

How much does Geothermal AC installation cost?

When considering a geothermal cooling system, it’s important to understand the initial investment is undoubtedly more expensive than a conventional central air conditioning system. However, the monthly energy savings will quickly help you recoup the costs. In fact, recent studies by the EPA show that homes utilizing geothermal pumps cutback energy costs by up to 70%. Use the Geothermal Savings Calculator to see how much you could save on air conditioning bills by replacing your existing cooling system with a geothermal energy system.

Factors impacting the cost of installing a geothermal cooling system include the type of soil you have, type of loop, and quality of installation:


The presence of rocks and the thermal transfer capacity of your soil can impact the payback and cost of installing a geothermal cooling system. It’s of the utmost importance that you work with a reputable HVAC contractor who specializes in geothermal energy.

One of the most important factors our geothermal experts look at is the thermal transfer capacity of your soil. If your soil is conducive for heat transfer, you’ll get a higher return on investment because a geothermal heat pump depends on the system’s ability to transfer heat away from your home efficiently during the cooling process.

Rocky land makes installation increasingly more difficult because the presence of rocks can interfere with drilling for the looping pipes.

Type of Loop

The type of earth loop will impact the cost to install a geothermal cooling system. While all types of systems effectively link to the geothermal heat pump, the main difference in functionality is how the systems use the water underground. Our geothermal experts will help you decide if an open loop with reinjection, open loop with surface draining, vertical closed loop, or a horizontal closed loop geothermal system is best for your home; a vertical ground loop is most common because it requires minimal space.

Quality of Installation

It’s true you get what you pay for. Hiring a licensed HVAC company like Capital Heating & Cooling who specializes in geothermal HVAC systems will cost more than hiring a company who does not specialize in geothermal energy. However, with the increasing popularity of geothermal energy, it’s imperative to work with a top HVAC company who has proven experience installing geothermal cooling systems. Since proper training and licenses are required to pull permits and engineer the best customized geothermal heating and cooling plan for your home, hiring an underqualified HVAC company could result in improper installation.

Tax Incentives & Financing Available* for Geothermal Cooling Systems

In addition to providing tips on how to save money on your air conditioning bills, there are tax incentives available to incentivize you to install an eco-friendly geothermal cooling system. Installing a geothermal heating and cooling system qualifies you for a onetime tax credit of 30% off the total cost of the ground loop or ground water geothermal heat pump. The tax credit is available through December 31, 2016 and to qualify, your geothermal system must meet or exceed EnergyStar requirements.

Qualified Geothermal Cooling Systems:

  1. Use the ground or ground water as an energy source to cool your home
  2. Meet the requirements of the Energy Star program which are in effect at the time the equipment is installed. (Ask a Capital Heating & Cooling comfort consultant for details.)

To file for the tax credit, homeowners can complete the Renewable Energy Credits subsection on their tax return forms.

Capital Heating & Cooling also offers geothermal financing plans with approved credit* allowing you to make payments over time.

*Financing subject to credit approval and terms.

What are the benefits of Geothermal Cooling?

Geothermal cooling is becoming increasingly popular due to its small carbon footprint and big energy savings. The main benefits of a geothermal cooling system are the long term savings you’ll see each month with lower air conditioning bills, and a sense of good knowing you’re cooling your home using a system that doesn’t pollute our environment.

How to Choose the Right HVAC Company to Install Your Geothermal Cooling System

Due to the increasing popularity of geothermal HVAC systems, many Milwaukee HVAC companies are jumping on the bandwagon and claiming to “do geothermal.” While we applaud the movement towards more green solutions, this leaves homeowners vulnerable to their learning curves. For over a decade Capital Heating & Cooling has specialized in geothermal HVAC installations, repair and maintenance. A qualified geothermal HVAC company should:

  • Have experience installing geothermal systems
  • Be knowledgeable about geothermal energy
  • Be licensed and insured
  • Employ NATE Certified Installers
  • Have written guarantees to back their installation work
  • Offer annual maintenance plans
