" . . .  I only recommend 'DX' Geothermal to my clients.  I won't  do water loops, they just don't work.  The Geo Group is my company of choice.  When my clients are happy, I'm happy.  From engineering to installation to customer service , can't ask for more than that"

 ". . . We did a gut renovation on our 4800 sq. ft home.  In selecting a new heating and cooling system, we wanted a heating and cooling system that was environmentally friendly, long lasting and easy to maintain. After thoroughly researching the geothermal space, we turned to our contractor who recommended the Geothermal Group.   We met with Paul Auerbach and quickly entrusted him with the project. 


From the the proposal through engineering, design and installation, the  Geo Group proved themselves highly professional and masters of their craft.  They were extremely responsive to both the builder and us.  More importantly, when unexpected issues arose, they responded with creativity and stayed within budget.   Along the way, I had many questions and Paul always made himself available to answer them. 


It's been nearly 2 years since the system came on line, it's performed beyond my expectations.  The indoor comfort can't be beat.  As an added benefit, the cost of heating and cooling is not only less than projected, but with our solar panels, it's minimal. With the federal and  state incentives, investing in geothermal system makes financial sense. But the system's ultimate success and your level of satisfaction, depends crucially on who designs and installs it. I recommend the Geothermal Group wholeheartedly.

" . . .  In 2010 Paul and his team installed 2 DX Geothermal Systems in our 1850's home.  We're delighted to be early adopters of geothermal.  We continue to appreciate the comfort and savings that come with having geothermal. Like all mechanical devices, things happen and  failures occur. The Geo Group has always come through to take care of any issues.  Last summer the Geo Group arranged to change out an old air handler which was installed prior to the geothermal systems.  The Geo Group took are of everything, and in addition, secured incentives that covered 50% of the cost.

" . . . We're one of the very few homeowners who have both a water loop system and a DX system at our home. The main house has a water loop system and the guest house has a DX system designed and installed by the Geothermal Group.  The DX system "kicks ass", It's far better!"

Bergen County

Our family made a decision to reduce our carbon footprint at our home in Bergen County, New Jersey.  The home, originally built in 1931, was due for a new heating and cooling system.  We had 2 boilers and 2 natural gas hot water heaters and numerous interconnected systems - burning thousands of therms of gas a year.

Our research brought us to the Geothermal Group.  We spoke to them about the potential of converting our home from natural gas to geothermal. They pre-engineered the project for a water loop geothermal system.  Gave us a price and started  the project.  They made complicated work look easy - bringing in a project manager and specialized teams for each of the various systems.  Part of the project scope was to maintain radiant in our kitchen and family room, and keep the Nest thermostats . . . no problem.

Our existing heating was operational until the new systems were ready to be turned on - we were never without heating or cooling.  The systems have been in place for only a 3 months and we already feel a difference in the air quality and comfort.  On top of reducing our carbon footprint, the projections show savings of 25% with the geothermal over gas.  Customer service has been extremely responsive during and after the job was complete.  We were so pleased, we also contracted them for our vacation home.  We highly recommend the Geothermal Group.

" . . . In 2019 our family wanted to convert from oil to a more climate  friendly system.  Our existing systems were old and ready to be replaced.  We hired the Geothermal Group, highly recommended professionals, to design and install the systems.  Having seen other geothermal systems installed, we were prepared for the drilling ripping up our side yard. To our surprise, the Geo Group came in with a precision drill and were done inside of a week, with minimal yard upheaval.   Geothermal has been a joy for us.

In 2011 I was designing a new home in Westchester.  As a family with small children we wanted to “go green” and were recommended to Paul and his team.  The installation went without a hitch and since  start-up in 2013 the system has already paid for itself.   It costs  less than $1300 a year to heat and cool the house. The comfort is amazing during all seasons.

“ . . . We had a really bad situation with a geothermal company in the Hudson Valley that failed to start work on a job after receiving a substantial deposit from us.   As we were in the midst of construction, delays are costly.  When it was apparent the original contractor wouldn’t perform, I contacted Paul Auerbach.  He brought in his team and saved the project. It’s hard to find a company with better professional ethics.   We’ve since worked on several jobs with them including a major project in New Preston and always recommend them to colleagues.  I won’t do a geothermal project with anyone else."

" . . .We were lucky to discover Paul Auerbach after another contractor failed to deliver.
In building a new house from the ground up (2010/2011) we hoped to engage in at least some element of green construction, but we were getting cold feet.  I ran across an old high school friend who said, "don't give up on geothermal".  So, confidence in Paul and my friend's push sent us forward with Paul's DX system.  As with most endeavors there have been quirks, but Paul has always been there for us.  Long after the system is in Paul answers every email and phone call promptly.
We love the quality of the air.  Its clean!  Never too hot or too cold.  We would definitely embark on this adventure again."

“ . . . We have a 6,000 sq. ft home in Westchester and wanted to switch from oil to geothermal.  This was difficult given the heating and cooling system was already in place.  The Geo Group was able to design a system that integrated seamlessly with the existing ducting system and kept features we wanted, like radiant.   The air conditioning and heating is a huge improvement over our original systems.  They provide excellent service and quality work. Always a can-do attitude in a timely fashion.” ​

James C. - Plumbing, Heating & HVAC Salisbury, CT

" . . . I’ve been in the HVAC business for over 35 years and seen my share of geothermal system disasters installed by hackers who didn’t have the technical savvy to do the job right. We’ve been involved with several systems ripped out and replaced with boilers and conventional central air.   I learned my lesson with geothermal until we met Paul and the team at The Geothermal Group. 
These folks are the most professional geothermal engineers and technicians I’ve worked with.  Paul Auerbach knows the technology and designs the systems so they work.  As a plumbing contractor I personally prefer the DX copper technology but these guys do it all.  Water based and DX system
