Geothermal Repairs & Service

In 1979, Hoveln Heating & Cooling, Inc. installed its first geothermal system. In the years since then, we’ve established ourselves as the experts in geothermal installations. If you’re unsure of what geothermal is or how it works, or the initial price tag has you a bit wary, let us walk through how this energy and cost efficient heating and cooling system works.

How Geothermal Works

In a nutshell, geothermal works like your refrigerator, but harnessing Earth’s underground temperature of a near constant 55 degrees Fahrenheit. This temperature is generally found in the upper 10 feet of the Earth’s surface. A geothermal heat pump circulates a pressurized refrigerant through the system, transferring heat in and out of the home.

The Geothermal Earth Loop

Most residences use a closed-loop system of either horizontal or vertical loops buried underground. The loops are made from polyethylene pipes, similar material to plastic food storage containers found in your home. High-pressure refrigerant circulates inside the loops, transferring heat in or out of the home depending if the system is set to heat or cool. Factors that help determine how much piping the system would need include:

  • Geographic location
  • Climate
  • Soil
  • Available land

Technicians with Hoveln Heating & Cooling, Inc. use these factors and more to find a geothermal system properly sized to your home and needs.

Common Types of Geothermal Issues & Repairs

As the geothermal system experts for Central Illinois, we’ve seen our share of geothermal system repairs over the years. And though we recommend regular maintenance and service many systems, issues still crop up from time to time.

Mineral and Deposit Build-Up

If your home has hard water, you may find a build-up of calcified minerals in the heat pump open loop. Hoveln Heating & Cooling, Inc. has cleared many mineral deposits from geothermal systems since we installed our first system nearly 40 years ago.

Ground Loop Leak

A ground loop leak may seem like a major issue, but often times, a simple dye test from one of our technicians will reveal the source. Once the leak is located, the ground specifically around it is dug up, the leak repaired, and loop recovered.

Advantages of Choosing Geothermal

One word: efficiency. From saving money on utilities each month to lower energy use to heat and cool your home, geothermal systems are efficient. Geothermal boasts double the efficiency of modern, top-rated air conditioning systems and nearly 50 percent more than top-rated gas furnaces. Homeowners who have installed a geothermal system report their heating and cooling bills dropped by 30 percent to 70 percent.

Though the initial installation cost may seem like an automatic deterrent, an Air Force Institute of Technology study found it only takes an average of seven to eight years to recoup that cost. Our knowledgeable technicians and staff can help determine how long it would take for your home to recoup the installation cost. Factors weighing into this include:

  • Local utility rates
  • Excavation/drilling cost
  • Level of insulation in the home
  • System/model efficiency
  • If your state or local utility company provide any incentives for installing a geothermal system
