Our Geothermal Installation Process


Screen Shot 2016-03-15 at 3.18.45 PMThe first step to finding out if installing a high-efficiency geothermal system is right for you, is to call us for a FREE, no obligation, in-home estimate.

  1. We will come do a heat loss/heat gain Manual J Calculation. With the use of sophisticated software, we can determine a properly sized system for your home. This is done on every estimate that we do for our Maryland customers. It’s extremely important, because properly sizing a geothermal system is the key to maximum energy savings and comfort. Simply using the same sized system that you currently have is not a determining factor to proper equipment selection.
  1. We will then provide you with a detailed proposal including a total cost with all of the available tax credits and local incentives.
  1. The drilling or loop installation will start next. This can anywhere from a couple days to a week depending on the size of the system.
  1. Once the loops are installed we begin to change the system over, removing and recycling the existing equipment and installing the new geothermal heating and cooling system. Changing the system can take a couple of days on average.
  1. After installation, we will have a post-installation meeting to go over the system operation and tax credit/local incentive(s) paper work.

As you can see switching to geothermal does not happen overnight. However, choosing the right Maryland geothermal contractor will make the experience pleasant and as unobtrusive as possible!

A Major Source of Energy Is Right under Your FeetTax Incentives for Choosing Geothermal

Your own backyard has the potential to be your source of heating and cooling comfort. Now you can get safe, reliable, energy efficient heating and cooling from one piece of equipment. Geothermal energy represents the leading edge of heating and cooling technology. It moves heat energy to and from the earth to heat and cool your indoor environment. And compared to ordinary systems, geothermal technology can save you 30% to 60% on your monthly energy bills. Geothermal is the safest, cleanest, most reliable space conditioning system you can buy

Geothermal Systems Provide Four Times the Efficiency

A geothermal system uses the Earth’s thermal properties in conjunction with electricity to provide unprecedented efficiency. For every unit of electricity the system uses, it
provides four units of heating energy, giving a geothermal system a 400% efficiency rating on average. These numbers can translate into real savings on your utility bills year-round.

Geothermal Systems Use Thermal Energy from the Earth

Geothermal energy is an unlimited resource. The lot surrounding a suburban home or other building contains a vast reservoir of low temperature thermal energy, typically 10 times that required over an entire heating season. This resource is constantly resupplied by the sun, the surrounding earth, and heat rejected while cooling during the summer. The universal definition of geothermal is “…pertaining to the heat of the earth.” By using the earth to provide up to 50% of a building’s total heating and cooling needs, GHP systems are truly geothermal energy made practical.

Geothermal Vertical Loop


A vertical loop is the ideal choice for a geothermal heat pump when available land surface is limited. Well drilling equipment is used to bore small-diameter holes from 100 to 400 feet deep.

Geothermal Horizontal Loop


Horizontal loops are typically used when adequate land surface is available. Depending on the geothermal system needs and space available, pipes are placed in trenches that range in length from 100 to 400 feet.

Open Loop


Open loops are also referred to as Well Water Loops, and in ideal conditions, an open loop installation can be the most economical type of geothermal system. An open loop configuration uses groundwater from a well as a direct energy source.

Geothermal Pond Loop


Also called a Lake Loop, this method is a very economical way to install when a large body of water is available for use near the geothermal heating and air conditioning system. Coils of pipe are placed on the bottom of the pond or lake to capture and exchange the geothermal energy.
