“Toby was on time, polite, efficient, and explained everything in language I could understand. I had one question that my previous service company could not answer. Toby answered it after a brief exam of the equipment and eliminated five months of worry in seconds.
Excellent experience from my initial contact to the time Toby left the house. I'll see you guys for my fall tune up!”
“Outstanding company, staff, and service today for my introduction to Ground Loop. Immediate service and sales appointments scheduled by Christian and Caitlin same day as first call inquiry. Antonio performed super tech service on my HVAC unit, then confirmed consistent cool air from all vents inside. Refrigerant level good and steady. Capacitor sensor cleaned and needed that very much. Important issue for performance so the whole tech appointment was well worth it. Justin checked the flue juncture in attic at roof for evidence of leaks. No water stains there, and he brainstormed with me for many options. Helpful discussion. Now Ground Loop is my go-to and highly recommended HVAC company. Thank you so much.”
“Ground Loop installed our Water Furnace geothermal back in 2010, and we have loved it and their service ever since — including that they are always happy to work with you to tweak thing exactly how you want them. The unit works great, except on the extremely rare occasions when something breaks (like when the original compressor died in the middle of a real cold snap a few years ago) but then they immediately help you over the phone, to try to affect a work-around, and then come out real soon to do the actual repair — and they do it right the first time. Over the years, our unit has been serviced by numerous different Ground Loop techs, most VERY good; today Austin Hamel came out for a routine maintenance, and he was WONDERFUL — so very nice and helpful! The office personnel are also very nice, knowledgeable, and helpful!
If you are thinking of buying a geothermal, I bet you will love it. But be sure to get Ground Loop to install a manual over-ride switch for the electric back-up heat, as it is very expensive to run and otherwise automatically comes on if the unit has not reached your call-for temperature within a rather short while. Without that switch (which we always keep in the off position) you can not set the nighttime temperature of the bulk of your house (non-bedroom parts) back any substantial amount in the wintertime — which we enjoy the system being set to do, as that confers significant saving in energy costs.
Thanks, Ground Loop folks!”
“So far everything has been great! From the initial estimate to working with me through all of the financing I have had no issues. I was very happy that my wife and I found Ground Loop being all the way out in Laurel, MD.
Our installation was done days before the temperatures went above 85 and the house feels great, and the energy usage is so low compared to what we had with our old system. I can see this saving us so much money in the long run. Our thermostat said our system was on for almost the whole day (20 hours) on a day where the temperature outside was above 95F and the heat index above 100F. The energy usage was around 12kWh total or $2 for the entire day! The system running for the whole day is exactly what was told to us by Ted and also advertised by the WaterFurnace Series 7 model with variable speed.
Caitlin has responded to all my questions quickly and everyone on the team during the install have been so respectful and nice to work with.”
“Jason,
We have been quite satisfied with Ground Loop's responses to our calls for service, and for providing continuing periodic seasonal servicing of our two locations. On your recent service appointment, Toby was prompt for his announced arrival, thorough in his checkout of systems' operation, and left the service areas neat.”
“Easy and fast appointment, showed up on time. My technician Mason was very knowledgeable and informative, he was able to get my system up and running in a very timely manner.”
“We had our routine maintenance done with Ground Loop last Tuesday, February 4th. Our Technician was Mason who was courteous, efficient and professional. We received a call when he was about 20 minutes away and he was right on time. Thank you for continuing to offer top of the line service.”
“Ground Loop has been fantastic! Very professional. Gives great explanations. Always on time. Highly recommended!”
“I would like to thank Ground Loop for the timely response in sending a technician to determine the problem with my AC system. He was very polite, knowledgeable and efficient in analyzing the situation. Upon his completion, he indicated what had been found and that the office would forward a description of the cost and scope of work. Following approval and ordering the parts, it was only a short period of time for the system to be up and running. During the repair period, we hardly knew anyone was here. System now operating better than it has for several years.”
“Ground Loop just completed a geothermal installation in our home. From start to finish we could not be more pleased. Ted Evans came out to our home and explained the system and installation process. He then examined the site, measured the house and presented us the quote. All of our many questions were answered at that time. After the wells were drilled Ground Loop began their installation which took approximately 2 days as promised. All of their employees were very knowledgeable, professional, and respectfully. They were very detail oriented, and the final outcome reflects that. The county inspectors were on site the other day. During the inspection on of them commented to me that he was not just glossing over the inspection. He takes the inspection very seriously, but he knows from experience that when he is coming out to look at an installation by Ground Loop, he’s not going to have a problem. Things will be done right.
Highly Recommended”
Ground Loop has been very responsive to my needs in terms of scheduling. Also, they have arrived on time and are good at communication. I consider the ability to stay in touch with any service provider important and am pleased with their attentiveness.

“Ground Loop, and in particular, Toby and Scott, get 5 stars for finally resolving what had been many years of frustrations regarding my geothermal cooling upstairs. The system installation, and its bi-annual maintenance, had been performed by another company. I had complained for several years about the upstairs cooling not being able to maintain at the thermostat setting during the hot summer days. They offered a variety of ideas, including the installation of a new air handler (an expensive non-fix), none of which improved the cooling. My builder suggested Ground Loop for a second opinion. Toby immediately observed multiple compressor leaks as well as poor pressure readings. Mind you, the system had just been inspected 2 months earlier by the installation/maintenance company. Scott made recommendations and oversaw the work. Finally, my upstairs is maintained at the thermostat setting for the first time in many summers. These guys are professional and knowledgable, and communication has been great! Highly recommend!!”
“Ground Loop to the rescue! We called on a Sunday because our AC unit had locked up. Jason came to our home the next morning at 8am to take a look at our unit and he had us back up and running within 30 minutes! He was professional, knowledgeable and very responsive to our need for AC, with the summer heat and with a severe asthmatic child in the home. We also knew we needed to upgrade our unit, as our home is older and we have baseboard heating units that are quite costly, to run, in the winter months. After speaking with Jason about our concerns and hearing the pros/cons of replacing just the a/c unit or getting a combo unit (A/C & central heat), we decided to purchase a combo unit and are looking forward to more cost-effective electric bills. We are awaiting the delivery/installation of our new combo unit, but the original unit that Jason came to fix has kept us cool since it was fixed! We cannot recommend Ground Loop enough and will make sure we tell all of our family and friends that this company cannot be beat!”
“Dear Mr. Cullum, I want you to know how extremely impressed I am with the people I’ve met from Ground Loop from Ted in Sales, to Emilie, Justin who came out to do the initial assessment, Joe the lead man and the two members of the crew who installed the unit. I have had many work crews at my house over the years and none were as professional, courteous, and competent as yours. You can take great pride in the culture of excellence and respect for customers that you have instilled in your team members. They are terrific and I will remain a GREAT fan of Ground Loop.
Most sincerely and gratefully
Mrs. Smith”
We had our neighbor recommend your company for our geothermal repairs. We had the pleasure of Shawn arrive promptly on the morning of August 5, 2020. He was polite and informative. He fixed the problem with our geothermal system very quickly.
“Ground Loop Installed a new two speed HP with a zone control and an Aprilaire 5000 air filter. I love it! It’s much more comfortable and I would never go back.”
“From the initial estimate appointment, through the install, and both maintenance visits they were on time or early. They completely cleaned up at the end of each workday. After 18 months of use, I have no complaints and I’m saving approximately 40% per month on my BGE bill. I highly recommend using Ground Loop for your HVAC work.”
“We used Ground Loop with great results to service the geothermal system in our previous home. We moved to a different place with oil heat that went through a $500 tank every 6 weeks this past winter. I contacted Ground Loop to help figure out why, as this was an open-ended task that required an experienced technician.
They identified a laundry list of items, including some big ones: A large gap in some hidden ductwork that was dumping much of the air into the crawl space, undersized returns and too many closed registers that cause the burner to overheat and cycle off to cool down, they fixed a clogged condensate drain that would likely leak water to the ceiling below, and that the previous owners made the penny-wise decision to install air conditioning instead of a heat pump, so oil is used for all heating.
These defects have been present for decades, and probably cost the previous owners a mint. A $297 investment in their thorough HVAC inspection was well worth it. We will definitely be contacting them when we go geothermal in a year or two.”
“I had Ground Loop install my system a few years back and have used their maintenance program ever since. My ground loop heating and air system runs great and I love how I save over 40% versus my standard system in my previous home. Ground Loop’s employees are always polite and super knowledgeable. I plan on using their winter & summer maintenance program to ensure my system is always working properly.”
“We have been using Ground Loop for our yearly maintenance on our geothermal system for 6 years. They are thorough and very courteous. Last month we had a ductless a.c. unit installed above our garage in a storage room turned office. They were great to work with! We highly recommend them!”
They are awesome! They did a wonderful job for us and we would refer this company to anyone.
We have been customers with Ground Loop since we built our house in 2001. When it was as time to replace the old system, there was no doubt that we would use Groundloop again. Now we have the Water Furnace system, more energy-efficient and trouble-free. We have the semi-annual maintenance service and we are always satisfied with the quality of the technicians’ work and professionalism.
“The system 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.”
“From the initial estimate appointment, through the install, and both maintenance visits they were on time or early. They completely cleaned up at the end of each workday. After 18 months of use, I have no complaints and I’m saving approximately 40% per month on my BGE bill. I highly recommend using Ground Loop for your HVAC work.”
“The installation went extremely well. Only one day of digging in the yard to install the ground loops. We had two units installed in the house, one in the basement and one in the attic, which took a bit over two weeks. The Ground Loop team members were extremely knowledgeable about their products. They were very courteous and professional. They arrived on time and cleaned up any messes they made. If you want a geothermal system, Ground Loop is the company to call.”
“The state and federal government subsidies made me start to seriously consider replacing my existing HVAC system. My old system would constantly run in the summertime and the house had difficultly keeping 70 degrees when it was over 90 degrees outside. I had doubts if the engineering would be sufficient because the rule of thumb is 200 feet per ton of cooling and the system is a variable speed 3/4 ton unit. I contacted the east coast representative for WaterFurnace (maker of the HVAC unit) and they assured me that 600′ would be more than sufficient. The outside unit was removed and the new unit is in my basement. It runs so quietly that most people can not even hear it. I can barely hear the unit (less noise than a refrigerator. The unit is designed to constantly run and the house has never been cooler. The unit has not failed me and I am looking forward to the winter to see how well it performs. The air quality has also improved because the unit uses large filters (up to #13 for maximum filtering) that are easy to replace and can be ordered online. The thermostat reminds me of when it’s time to replace the filter (@every three months). Ground Loop did an excellent job in engineering, installation, and maintenance. I had an issue with the thermostat giving an incorrect humidity reading. The technician came out the next day and swapped the unit out – still didn’t fix the problem. He contacted WaterFurnace and manually adjusted the internal sensor to compensate for the problem. I have owned my home since 1993 and this is the first time the HVAC unit has worked properly. Ground Loop sized the unit correctly and installed it in my basement without any problems or concerns. I highly recommend them.”
“We looked into a geothermal heat pump system several months back and Group Loop Heating and Air Conditioning were one of the companies that responded to our queries.
Fast forward to today, and they have just finished up the installation of our new system. These guys were really professional throughout the whole process.
Out of the 4 contractors, we contacted they were the only ones who actually showed up in a timely manner, their bid was on par with the other ones we received but it was their professionalism that really got them our business.
This was a complicated project and there have been a few bumps in the road, but the reason these guys get 5 stars is how they responded to them. Once all of the county paperwork was in these guys came out and cranked out the system installation and their finishing work is really impeccable.
I am super happy with the system and the service I received from Ground Loop and I feel very comfortable recommending them to anybody!”
