The cost of the system and installation is huge.
The necessity of adding a traditional system as a back-up for those extra cold days.
The repairs on a system like this are expensive.

The geothermal heating source, its usually an active or somewhat active magma chamber. Below all that hot water is something heating it up, and that something can erupt-- like volcanoes in Iceland or heating vents which occur near and in Yellowstone, which is believed to be a Supervolcano.

Price used to be the only con. Now with energy prices its hard to believe that this heating/cooling type hasn't caught on.
I have heard that in very cold winters you STILL need to supplement it with another heater, but still the savings would not change. I also heard that the heating and cooling is more uniform, meaning no cold/hot spots.

The main cons are the high initial cost and the possibility that you may need additional conventional heating/cooling to fully meet your needs. Geothernal heating/cooling also may or may not be feasible depending on the geology of your location.

three cons:
1. they cost a lot
2. they are difficult or impossible to install in some situations (not enough yard, inpenetrable soil, etc)
3. you still have to have conventional heating/air conditioning systems but they don't have to do as much work to maintain chosen temperature
