Geothermal Ratings, A Repairman Ranks The Brands...

With our geothermal ratings, you can cut through all the sales hype and find the best value. We've already performed the research and ranked them for you. We have given each brand a rating of from 1 to 5 stars. A 5* rating means that, if we were shopping for ourselves, we would most likely choose that brand. If more than one brand has that rating, we would choose the one with the lowest price.

For your convenience, we have included the web addresses for the manufacturers. We have also included a GOOGLE SEARCH box to help you to get more information without leaving this page.

If an NA appears in the place of stars, then that brand does not have a unit available in that class or we could not find enough information about it to make an informed rating.

We have separated the units into three basic types which are split systems, packaged systems, and direct expansion systems.
