No. Geothermal systems are virtually maintenance free. When installed properly, the buried loop will last for generations. And the other half of the operation - the unit's fan, compressor and pump - is housed indoors, protected from the harsh weather conditions. Usually, periodic checks and filter changes are the only required maintenance. (Note: Water Furnace has developed a geothermal unit - the ES Split - that is so rugged and quiet, it can be placed outdoors when that's the best solution).
