“A very belated thank you for your magnificent job at the Lakes Region Energy Expo. Your workshop was superb and hit on everything we could have wanted. People were completely engrossed. We were thrilled not only with the numbers of people who attended, but what was most rewarding was the level of engagement. People didn’t come, look and leave. The majority stayed for much of the day! The geothermal site tour (of the home next door to the event) and knowledge that your company brought to the event was so valuable. “

— Nancy Hirshberg, Stonyfield Farms

 

“The system works great and we are very pleased with the high quality of work. We were able to lower the temp from 68 to 66 because the air circulation is so much better and there are not anymore cold spots in the room vs. our old system that we took out. Thank You for a great job!”

— Mark Emerson, Townsend, MA

 

“Just want to say how impressed we are with everything your crew accomplished today—amazing! I also appreciate how neat they have been as I know they are moving things around, as well as cutting holes in various things. Thanks.”

“I came up to NH this weekend to inspect the work – the system looks and works great. Many thanks for a job well done. I’m impressed that Ultra Geothermal’s original estimate came in on target and on price. The workmanship is excellent throughout and it is great to have the system operational. I’m pleasantly surprised that the retrofit worked so well. I’m extremely impressed and satisfied with the system and would love to talk about it to anyone interested. Again, many thanks”

“We are very happy with the geothermal installation that Ultra Geothermal has performed. I believe this is the heating for the future. If anyone in the future is looking at this option for heating and cooling I am more than happy to talk with them about this. Thank you for all your hard work, everything works great. All of the men did a great job and it looks excellent. “

“When my wife Cindy and I were investigating geothermal heating we found it to be a bit overwhelming because it’s just so different from what we were used to and we were afraid it would be a costly mistake. Now that we’ve used it for a year and see how great it is compared to every other heating system we’ve used (electric, wood and oil) we wouldn’t want other folks to be afraid and therefore make a bad decision to stick with oil or gas. I had the opportunity to work alongside Ultra Geothermal’s crew as I did the wiring. I also have records that prove the cost savings versus oil and of course my son Scott is a happy Ultra Geothermal customer also.”

— Gary Toussaint, Merrimack, NH

 

” Once again I feel good all over. I appreciate the extra effort and we feel very satisfied with the service that is provided by Ultra Geothermal. It ALWAYS holds true…the real test of integrity of a company is not just in how well everything went on the front end but what happens when you have an issue and need service. Your whole crew represents Ultra Geothermal very well in the marketplace and you should be proud to call them associates. “

— P.E., Milford, NH

 

” I just wanted you to know how impressed I was with Ultra Geothermal. Not only did you get someone over here yesterday, but the technician fixed the problem that my previous heating contractor could not fix. You service technician went out and got a new part, and voila it was fixed. I would recommend Ultra Geo to anyone. “
