Overall I am extremely happy with the services offered by Ground Loop Heating and Air Conditioning. I have an older home (built in 1928) and it still had steam radiators and no air conditioning besides window units. This was a very large job, involving retrofitting the home with ductwork to heat and cool every room, remove the old boiler unit, and install the geothermal unit and ground loops. To complicate matters, the home has a completely fenced yard that limited grounds access to dig the loops, and the city permit office has constrictive rules on where you can dig the holes in reference to other properties.
The estimator/project manager, Jason, was very easy to communicate with and I always felt he was being upfront with me on the status of the project. His office staff was also very communicative and even helped with the rebate process to ensure I received all the possible rebates. Great Stuff!
The installers were professional and did extremely quality work. The city inspector even commented on how well the ductwork was installed. There was an electrical sub-contractor (I didn’t catch the name), but they were efficient and professional.
There was also a sub-contractor that dug the wells, Allied well drilling. Their employees were professional and courteous, but it did not seem that the on-site personnel were empowered to make decisions. This did lengthen the timeline of the project.
That is not to say this was a perfect project, but I can say empathically that Ground Loop went above and beyond to complete the project with no increase in price, despite several unforeseen issues..
All in all I was very happy, but I do have some things to consider if you are considering a geo-thermal system :
The project went well over the projected timeline. While this was not an issue for me (if a bit frustrating), if that is an issue for you, you may want to negotiate some timeline penalties with them before you sign a contract.
Most of the delays came from changes in the layout of where the wells were supposed to go. It went from 02 wells to 08 wells, dramatically increasing the time required. You may want to consider having the sub-contractor confirm your local regulations and placement of the wells prior to signing a contract.
If you have not had a core sample done (who has?) be aware that there is no way to predict the material makeup of the ground 300 feet down. This may necessitate a change in equipment or drilling method which will add time. It is a necessary evil, and can’t be avoided unless they can use their full size well rig on your property. They couldn’t on mine, and it caused issues. In retrospect, if I could have moved a shed or some fencing, I should have. Be flexible.
Lastly, be prepared to have your yard torn up. It rained a lot during the install, and they needed water in the drilling process, so my yard is beat up, but again, this is the nature of the work. If this is an issue for you, they offer hand raking and restoration at additional cost. If you don’t want to put in some work after they are done, you should opt for that option.
The end result however is fully functioning system that is very inexpensive to run (the other day it never got above 35 and it only cost $3.89 to operate). I am very happy, and could not recommend these folks more highly. If I had to choose again, I would make the same call.

geothermal heating and air conditioning system and had wanted to upgrade my
home for many years. After our recent extra
cold winter and spending thousands of dollars on expensive heating oil, and faced
with an impending failure on my 19 year old air conditioning system, I decided
that this year was the right time. I
contacted a number of area HVAC installers as I performed my due diligence,
finally selecting Ground Loop, a company in business since 1991 that does
geothermal systems exclusively. I never
regretted that decision.
I have been around a while, and have decades of experience
with various contractors. Ground Loop
not only exceeded my expectations, they did truly outstanding work at a very
competitive price. This was a large job
and the installation involved drilling two 400 feet deep vertical wells in my
back yard and connecting them to a state-of-the-art geothermal system
manufactured by Waterfurnace in my basement and replacing my entire hot water
system (which also used heating oil) as well as all electrical and plumbing
work and removing my inside oil tank and the external a/c compressor. There were many unique challenges including
the fact that I live on a very steep hill, with limited access to the area
where the wells were drilled.
Jason Cullum, the Ground Loop Project Manager, worked
closely with me throughout the entire process and staged the work to ensure
that I would have heat and hot water at all times. He also installed the hot water components of
my choice, necessitating special trips to the supplier that I had
selected. The sub-contractors selected
by Ground Loop (drillers, electrician, and plumber) were all first-rate as part
of the process. The Ground Loop
installers, project foreman Butch Lawrence and Brian Serra, were professional
and seasoned, with many years of experience.
They also were courteous and friendly, explaining everything to me as
they proceeded. They even pointed out
some existing issues such as loose ductwork and repaired it. An outlet was installed to take advantage of
the extra electrical wire that previously had serviced the oil-fired hot water
heater. While they were sealing the hole
left from the heating oil tank, they also sealed an unrelated wiring hole. These guys truly went the extra mile always. Clean-up was fastidious.
All of this work was accomplished in the predicted time
frame ? several days for the drilling and several more days for the geothermal installation
? at a price that was thousands of dollars less than their nearest competitor. I would recommend this company to anyone contemplating
this technology and I look forward to many years of working with Ground Look to
maintain my geothermal equipment.

Ground Loop broke ground a week before Thanksgiving in 2013 and was pretty much done with the installation a week before Christmas. In total, I counted 18 business days for the interior install plus 4 days for drilling the wells. Now, if you read all that Ground Loop did for us and kept in mind that there was a holiday in between, I would say that the installation went by pretty quickly.
From the start, the main reason why I liked Ground Loop and chose them (after interviewing 3 other potential providers) was I liked the project manager- Jason. The main thing I liked about Jason was he was willing to work with our desires. For example, no other provider wanted to touch twinning the 2 systems that were originally in our house together. But Jason came up with a plan to make it work. That's the way he is- always finding a way to make things work.
I would also like to note that while all providers were competitive on cost, Ground Loop was actually slightly more expensive on the bottom line by like $2,000 (keep in mind the total cost and see that this is less than a 5% difference). BUT, I felt the value of the work that Ground Loop performed was more than what the other providers were willing to bid. I already mentioned the twinning of the 2 systems, but as further examples, only Ground Loop was willing to add extra returns and supplies at no extra cost. Also, while the other providers were quoting me for buying and installing a whole-house dehumidifier, Jason agreed to let me buy the humidifier of my choice and then have them install it at no additional charge.
As some of you have noticed, it has almost been a year since Ground Loop completed installation. So why wait until now to review? Well, with Ground Loop, they give you 2 free maintenance check-ups in the first year after installation. I just had my second maintenance check and I am happy to say that everything is still working fantastically. The only maintenance required was a firmware upgrade of the system as well as a procedure to increase the pressure in the ground loops. Both were done well and without issue.
The last thing I will note is a point of improvement that Ground Loop could make- attention to detail. Over the course of the year, I noticed 2 things that I had to have Ground Loop come back to my home to remedy. The first has to do with the ground loop's point of entry into the basement. Basically, those entry points were not sealed and so one warm spring day when all the snow outside was melting, I found that the entry points were leaking water from the outside! The second item has to do with the dampers that are used for zone control. At the time of install, the dampers should have been insulated (according to the installation manual) but since they were not, a whistling sound could be heard in the vents.
In both cases, I called up Jason and he graciously took ownership of these issues and had his crew come back out to remedy the problems. I am happy to report that the leaking problem has gone away and I no longer hear whistling in the vents. The motto here is, Ground Loop works until they get it right. But I think it goes without saying that it would be best if Ground Loop can get these details right on the first try. Just from observing the dampers having to be taken out, insulated and put back in, I think it is clear that it would have saved a lot of time and trouble had the insulation taken place before installation.
Overall, I am very pleased and know for a fact that I have saved tons of money on my electric / heating / cooling bills. Just to give you an idea, all the homes in my neighborhood are the same size. My largest heating bill last winter was $330. My neighbor's was over $700!!! BGE rates our home as one of the most efficient homes in our surrounding area. We are 20% more efficient than our most efficient neighbors in the summer cooling months. What can I say but WOO-HOO!!!
