Accutemp installed some of the first geothermal heat pumps on Vancouver Island between 1980 and 1985. At that time air-to-air heat pumps were not as efficient and geothermal heat pumps made sense. A geothermal heat pump requires a substantial amount of civil work to be completed either by way of drilling holes in the ground or digging trenches. The drilled hole or trenches are then filled with a special resin polyethylene pipe. Special glycols then provide a means of heat transfer from the ground to the pipe to the glycol. Geothermal heat pumps are very efficient to operate. However, the cost of the groundwork makes the overall system very expensive compared to a good quality air-to-air heat pump. On average the investment in drilling the holes or digging the trench range $15,000 to $20,000. When added to the cost of equipment the geothermal heat pump system can be cost prohibitive. On that basis, Accutemp recommends investing in high quality air-to-air heat pumps and no longer installs geothermal.
