“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.”

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!”

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.

Your customer service was wonderful. It was refreshing to talk to an actual person so quickly when I phoned your company. I was very happy with your company from start to finish. My only regret is that I didn’t find your company sooner. However, you have our business in the future.

“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”

“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.”

- Matthew E.

They are awesome! They did a wonderful job for us and we would refer this company to anyone.
