  • Our Mission

    Ground Energy Support strives to provide high quality data and objective analyses to support the ongoing development of ground source heat pump technology.
  • What customers say:

    • Your system has been absolutely crucial in helping me monitor problems as they occur, right at my fingertips. Doing without it would be like driving a car without any gauges. - Pete W., Homeowner
    • It is interesting to follow the data and understand what the system is doing. …Love this information, wish I had known about it before – I am really glad I installed it. – Steve H., Homeowner
    • I look at it every day! -- Paul B., Homeowner
    • I did not know that my oil heat circulator was cycling on every 6 hrs until this monitoring showed me that. Why add heat 4 times a day in summer?! I turned it off after GES alerted me to what was happening.” Pete Tavino, P.E., IGSHPA Instructor
    • I have been checking the GxTracker, and noticed that the total heat rejected was less than it should be. I checked it out and the machine was a little low on refrigerant so I recharged it. I checked the website and system efficiency improved by almost 40%, cool! -- John S., Geothermal Professional
    • We just ran the AC for first time last night … Pretty cool to see all the data! -- Greg M., Homeowner
    • Well, more “kudos” to Ground Energy Support. I just got a call from my installer who will address this issue. Again, thanks so much for everything. --Joseph P., Homeowner
