Geothermal Heating and Cooling

Closed Loop Geothermal JobGo Green with Geothermal

Have you heard of Geothermal? It's amongst the leading cutting-edge green energy technologies available today. Geothermal is changing the way residents and business owners in New Hampshire are efficiently heating and cooling their homes and businesses.

It's not as new as you think

You may be surprised to find out we've been installing Geothermal systems for over 15 years. The difference is that back then it was kind of a novelty and today it's becoming more common all the time now that it has become more affordable for the average homeowner.

What kind of buildings are candidates for geothermal? All new construction or existing stand alone homes, condo communities, commercial buildings, and schools. The conversions are relatively simple, especially if you already have forced hot air. You won't find a more efficient way to heat and cool a home. The heat is comfortable, moist and temperatures are constant. Your indoor air quality will be improved and you don't use any fossil fuel.

Geothermal is how you go green.

  • George Craggy

    Jonathan, I wanted to drop a couple of lines to tell you how satisfied and happy that I chose Capital Well Co. for my water needs. From your lead man Steve to your drill people, your plumbing guy and your guy on the back hoe. Everyone that cast a shadow on my door threshold were polite, professional and willing to take the time to explain and answer my questions; which were many . Jon, it was my pleasure to meet you today and pleased that you came by for a follow up visit and explain how the heater works. SO...if I get a chance to tell everyone that needs a new well, I definitely will. It is apparent there is no "I" in your team . Thank you everyone.
  • Richard Meaney

    Mr. Swain, Thank you so much for the service Capital Well provided at my home today. I left a message with you at the behest of Ed Monty. I received a prompt phone call from Greg to arrange for a service call and to discuss what might need to be done. Promptly at (actually a few minutes before) the scheduled time, Bobby showed up to perform the service. Bobby was excellent at explaining the service, why some things were needed and how the well and pump worked, and answered all of my questions to my satisfaction. All in all, this was a very positive experience for us. Thanks to you and the people at Capital Well for prompt, courteous, and efficient service.
