Geothermal heating has two main selling points:
- It has a much lighter strain on the environment than fossil fuel burning systems
- It’s relatively maintenance free
It’s hard to argue against the first point as a series of loops underground that harness the constant temperature of the Earth and turn it into a sustainable way to heat your home is much better than most alternatives. The second fact, though, is debatable because although the tubes deep underground will likely never need servicing, there are some common heat pump problems that will be encountered over the years, particularly dealing with the above-ground portion.
Here are five common heat pump problems and how to fix them:
