Cleanest, Safest, Most Reliable HVAC Systems
Geothermal Heat Pumps give homeowners and companies the ability to reduce their carbon footprint while taking advantage of the most energy efficient heating and cooling system on the market. What makes a Geothermal Heat Pump so efficient is their use of the earth’s geothermal energy. The earth actually acts like a solar collector and stores heat deep in the ground. This stored heat, which remains a constant 55 degrees, can then be harnessed and used to heat and cool homes and buildings of all shapes and sizes. A homeowner using a Geothermal Heat Pump can expect efficiencies that are 400 – 500% higher than those of the most efficient traditional heating and cooling system. As a result, these homeowners will experience long-term savings with the added benefit of hot water.
Geothermal Heat Pumps are one of the cleanest, safest ways to heat and cool a structure. They operate on 100 percent electricity. This means that no carbon monoxide, carbon dioxide or other greenhouse gases will be emitted. Greenhouse gas emissions associated with the use of geothermal heat pumps are 55 to 60 percent lower than those from a standard air-source heat pump.
How Geothermal Heating & Cooling Works
Rather than generating heat, a geothermal system transfers heat from one place to another. The heat exchanger, commonly referred to as the geothermal loop, is buried in the ground and circulates a water solution through a series of pipes. This solution captures the stored solar warmth and delivers it back to the geothermal system located in the house. The geothermal unit then transfers the solar heat throughout the house using standard forced air ductwork or radiant floor heat to deliver comfortable indoor temperatures during the winter.
The same geothermal unit and underground loop system will reverse this cycle during the cooling season to provide air conditioning. The system removes heat and humidity from the air, then transfers and deposits that heat back into the earth through the same loop system.
The heart of geothermal technology is the geothermal loop system and by installing a geothermal loop system, it’s like getting a 70% discount on energy for the life of your home.
There are four basic types of geothermal loop installations; horizontal, vertical, pond and open. Three of these types – horizontal, vertical and pond – are closed-loop systems. Closed-loop systems use a continuous loop of polyethylene pipe as a heat exchanger. Horizontal and vertical systems are installed in the ground while a pond/lake system is installed in a body of water.
The fourth type of geothermal system is an open-loop and uses groundwater from a conventional well as a heat source in Winter and a heat sink in Summer. There is no significant difference in operating cost and efficiency between open- and closed-loop systems.
Here at Rabe Hardware, we’ll help you select the proper loop system based on a site survey and by conducting a detailed energy analysis of your home.
The Geothermal Benefits are Unmatched
Geothermal heating and cooling systems are quickly becoming the #1 choice for homeowners and businesses everywhere because the many benefits these high efficiency systems provide. Thousands of Geothermal purchasers have chosen to enjoy the following advantages of geothermal over a conventional furnace and air conditioning system.
Lower Utility Bills
The most efficient gas furnace has an efficiency rating of 98%. Geothermal delivers a 400% efficiency rating. That means for every 4 units of energy that are delivered, 1 unit of electrical energy is consumed. Geothermal systems transfer heat versus burning fuel to create it. This efficient use of energy transfer results in significantly lower operating costs.
Longer Life Cycle
Geothermal systems typically have a lifespan of 15-20 years rather than a 7-10 year lifespan on a conventional furnace and air conditioning system. The ground loop of the geothermal system (the pipes buried in your yard) is made up of polyethylene pipe, the same pipe which is used in city gas lines, and they have a lifespan up to 50 years.
Clean & Safe
Unlike other comfort systems, geothermal doesn’t emit any carbon dioxide, carbon monoxide, or other greenhouse gasses. There is no combustion in a geothermal heat pump; therefore there is no chance of carbon-monoxide poisoning – and by adding high efficiency air cleaners, a high level of indoor air quality can be achieved.
Geothermal heat pumps are very quiet and can be compared to that of a refrigerator. Not only are geothermal systems extremely quiet, but you can also forget about hot and cold spots. With geothermal your indoor air temperatures will remain at consistent levels and you’ll see an improvement in air purification and dehumidification versus conventional systems.
By using a modest amount of electricity and not burning fossil fuels, we can significantly reduce our impact on the environment. Versus a traditional system, a standard 3-ton residential geothermal system produces approximately one less pound of carbon dioxide for every hour of use. Over 20 years, that’s like planting 120,000 acres of trees or taking 58,000 cars off the road!
Bonus Hot Water
Offering more than comfortable living, geothermal systems even have the capability of capturing reclaimed heat during heating and cooling modes to heat domestic water. This application can reduce the water heating cost of a four-person household by as much as 50-60 percent!

What Our Customer’s Have to Say
Thanks for doing such a good job. Everyone was conscientious about their quality of work. I gave your name and number to several people who liked what they saw and I told them you were fair and honest to work with. I hope you get some additional business from this. Thanks again.–Ted Finch (Cedar Rapids,IA)
I love the Geo! If by chance I would build again, you would my first call for all geothermal, plumbing and electric. The people at Rabe Hardware are the nicest, hardworking people I have ever worked with. You guys have been great with my Mom & Dad and that means a lot to me. You have a five star business. No more buying propane or cutting wood for me! Thanks again.–Kelly Posusta (Douds,IA)
My wife and I wanted to pass along a big Thank You to you and your company. We couldn’t be more happy with what we have. From start to finish the process was extremely smooth. The first time I met with Jake to talk about the Geothermal I was really clueless about the entire system but Jake broke it down into simple terms and in the end there was no doubt in our minds that we were going to go with the Geothermal system. The scheduling process was smooth as was the communication with the guys on the jobsite. Coming from a homeowner who was acting as the General on his own home, this was very helpful. They were all very easy to talk to and were very accommodating to our requests, not to mention they were clean and picked up after themselves. Thank you again for everything, we sure appreciate it.–Matt & Alicia Hayes (Cedar Rapids, IA)
Matt was very knowledgeable, helpful and great to deal with–especially appreciate Rabe accommodating our needs to get the old AC unit disconnected so we could do some landscaping before the install the next day. The 3 guys who did the install were great too, efficient and thorough in cleaning up, etc, and showing us how to use the new thermostat. Thanks so much!–John & Dawn Stoakes (Dysart, IA)
We would like to thank every person at Rabe Hardware for the pleasant and professional work we received in the installation of heating, plumbing, and electrical contracting. We constructed a new home in 2005, after visiting with Jake Rabe. We took his suggestion and installed a Geothermal unit. The unit surpassed all expectations, both in comfort and low operating cost. Help with electrical and plumbing installation was great. The products are quality, the staff super and service exceptional. It was a very good experience.–Denny & Wendy (Keystone, IA)
I love my air conditioner!! I wish I would have had it installed sooner. It runs so quietly and boy does it cool things down quickly. The guys from Rabe were fantastic. Very professional and friendly. One of the parts was wrong so they had to make a trip to get the right one and then it got to be about 4 and I asked if they were done for the day and they said, you don’t have air yet, so they stuck around and finished up the job instead of coming back the next day. The next day a tech came out to check the AC to make sure everything was working properly and then a few days later I received a follow up call asking how everything was working. The guys at Rabe’s are great!!– Stephanie Hofmaster (Newhall, IA)
