MSNBC Reports on the growing interest in Geothermal energy:

Foley Mechanical Inc. is a company who has always made it a priority to evolve with modern HVAC services. In the past we embraced the movement away from R-22 refrigerant and began to install Puron units, a change that helped to protect the ozone. We are now introducing a new technology to our service that will continue to aid us in becoming more environmentally conscious. The new Carrier Geothermal Puron Split System Condensing Units (50yds) are factory matched and ARI rated with much of the indoor products that we have been installing for the past 10 years. This new and exciting product can allow for the installation of Geothermal Technologies in applications that were never before thought possible. With the addition of a NIM (Network Interface Module) we can even integrate a geothermal unit with a new or existing Carrier Infinity System.

Geothermal Basics
Almost everywhere the earth temperature from 10 feet to 200 feet remains relatively constant. A Geothermal system consists of pipes buried shallow in the ground, or in the case that space does not allow in vertical bores. In the summer the Geothermal Heat Pump removes the heat from your home or building and stores it in the ground. In the winter the Geothermal Unit essentially returns the heat that was transferred to the ground from the summer months back into your home. The excess capacity that is inherently available is deposited into a hot water storage tank. This description is only for a very small example, for the Geo-exchange resource that is available.

Residential Projects
Foley Mechanical designs ground coupled heat exchangers based upon our client's needs. Long term reliability is of utmost importance. Economics and payback on investment follow closely behind. We can take a look at your property and determine whether an open loop, closed horizontal, or vertical closed bore field is necessary.

Financing
Many avenues are available for financing this type of work. Please do not hesitate to contact us at our office for the financing opportunities we offer.

Larger Projects
A test well provides the information we need for local geology. The results of the testing provide information about soil thermal conductivity, diffusivity and resistivity. Our team of designers uses this data to determine bore field depth, location, number of penetrations, and amount of grout needed. The urgency of a test bore can not be over emphasized.

Grout
Foley Mechanical Inc. only uses Geo-Pro thermally enhanced grouting products. Geo-Pro is responsible for pioneering thermally enhanced products for the Geo Exchange industry. During this process they have raised the awareness of the importance of thermal conductivity within the vertical bore annulus. Geo-Pro Thermally Enhanced Grout builds the most efficient bridge between our Carrier Geothermal Equipment and an infinite source of free energy in a vertical bore.

Equipment
Foley Mechanical Inc. has remained loyal to Carrier Corporation, the inventor of air conditioning, for most of our equipment needs. Carrier Corporation is our provider for Geothermal equipment as they remain to be the world leader in technology and local factory support. Their product line is the most diverse available, they pioneered the "Freon Free" product back in 1996 and have been upgrading it many times since then. No other manufacturer has been able to develop a product more efficient and reliable, all competing manufacturers have had to follow in the shadow of Carrier's success. Carrier Corp is part of the United Technologies (UTX NYSE) family of companies and remains the world technological leader in the HVAC industry.
