Ground Loop Heating and Air Conditioning, Inc., is a third-generation family-owned heating and air conditioning business specializing in WaterFurnace geothermal systems. What started as a small sheet metal company in Maryland is now one of the most established geothermal companies in the entire country.
According to the U.S. Department of Energy's Energy Star program, leaky ducts in attics or crawlspaces can account for 20 percent or more of a home's heating and cooling energy losses. This results in higher utility bills for you and difficulty keeping your house comfortable. Run your system, and check all the ducts and joints you can access.
Most people immediately think of furnaces when opting to heat their homes. However, boilers provide a highly effective heat option, have a long life, can reach high heating efficiencies, and some types require little or no pumping energy. Boilers are an important part of a central heating system. They're a continuous closed loop of pipes carrying heated water (or steam) throughout your home.
You may have heard about ductless heating and cooling systems, but do you know about their advantages? The most common HVAC systems are central air conditioners and heat pumps that use ducts to deliver conditioned air throughout a building. Ductless systems are more flexible than traditional systems, because ductless systems don't use ductwork.
Gas-burning fireplaces are becoming increasingly popular. With the flip of a switch, you can sit back and enjoy a cozy, warm fire without the effort and messiness of real logs or smoke and fumes. Gas fireplaces burn with up to a 90 percent efficiency rating, meaning almost no pollution. Good for you, your home, and the environment.

Excellent, professional service. Had a 4 ton ground loop involving two 400 foot wells installed in 2009, including domestic hot water heating, with great installation and service/ support over the past 12 years.
This system helped our family conserve resources, and the earth as well, as we have stayed comfortable.
Thank you to the Groundloop team!

We have used Ground Loop for 16 years. They installed Geothermal heating in our home while being built and also radiant floors throughout the home. Ground Loop upgraded our system a few years ago. It is extremely efficient. Response is very good when we have an issue or a question. We would recommend this company.

They contacted us to let us know they didn't work on a certain thing and that they forwarded our information to another company that did the work. Thank you Ground Loop for helping us!

I have recently had the pleasure of hiring Justin Bowman to work on my geothermal system. Let me just say
I have never met a man at such a young age be so competent, knowledgeable and able to take customer service
To a whole new level. Previously I had two different companies supposedly maintaining my system. Little did
I know just how incompetent they were. My system had only been working at 25% capacity, the settings were not
set properly, and my system always ran poorly since being installed. Thankfully I found Justin who saved
the day. He knew exactly what the problem was and what to do
