I replaced my gas heating with a heat pump and ground loop last year. Removed my water heater and HVAC, for two 500 feet deep holes in the ground. Electricity bill is low, and gas bill is gone. You can receive tax breaks from federal, state, and local utility companies (in the US) too. While I do recommend it, you may need to wait for an available drill if the terrain under your property is difficult to dig through.

How much were the holes? Do you know temperature at that dept?

  I recently paid $12/ft for the drilling plus a bit more for excavation to connect them together and run to the house. Temp is 52f from our loops. Supposedly very consistent once below the frost line (6ft or so). All depends on the region you are in.

  Excluding all the bells and whistles, as well as the incentives. The ground loop and heat pump package comes to $48k. However, I paid significantly less than that even with all of the additions. As the incentives and discounts reduced it by about ~14k. The tax credits are ~13.5k, which won’t be realized until this upcoming tax season.

This is where I need to be eventually. I'm hesitant because I'm worried that I won't find any competent installers in my area and I'll end up with leaks, polluted well water, etc... Any troubles with the ground loop so far?

  No issues whatsoever with the ground loops. They will supposedly outlive the lifetime of the home according to the installer (~120 years). Only issue I’ve had at all is with the thermostat, which is an Ecobee Pro. While these smart thermostats are okay, they seem to mess up some of the more basic requirements of a thermostat, compared to the older dumb models. For context, the system went live in January, all permits cleared in November. So about a year of use.
