Odd, here drilling far eclipses excavation costs. Horizontal systems just need a backhoe to install, as you only need to dig below the frost line (we also get down to about -40 in winter). Vertical drilling requires more specialized equipment and so is more costly. Vertical systems are about $10k more expensive than higher end horizontal systems.
