I have been doing a bunch of research into geothermal recently and this doesn't seem to match with what I have seen. But it probably also varies a lot by location and such. They appear to still be about twice as efficient as an air to air one, and have less parts and maintenance (no outside unit to deal with). Yes the initial install is a lot higher because of the drilling but that should last for decades. In the US there is also 30% rebate at tax time which helps cut the costs down a bunch too.

You're looking to spend at least $30k if you need a vertical system, probably a lot more. And from what I understand, they ground loops inevitably don't reach their expected lifespan, so you'll be drilling new holes sooner than later. If you live in a very cold climate, I suppose with tax credits it could make some sense. For most people, AC + Natural gas is the cheapest way to go.
