Expert advice
A geoexchange system is an important installation and investment; therefore it is essential that you get good advice before making a purchase. The specialized team of AubinPelissier can guide you in the right choice of technologies for your needs. With extensive experience in geoexchange installations, we have the know-how to make your system the best it can be.
Certification
AubinPelissier has been trained and certified by the Canadian GeoExchange Coalition (CGC) in the design and installation of geoexchange systems for small buildings. This is your guarantee of our competence, and it also provides you with access to energy-efficiency grants from Hydro-Quebec and Natural Resources Canada.
How geoexchange works
The geoexchange heat pump is an energy transfer system that draws energy from the ground to heat or cool a building. There are two ways of doing this: (1) a closed loop system buried in the ground, either horizontally or vertically, containing a heat-conducting liquid; or (2) an open loop that draws up groundwater from an underground source.
Vertical closed system 
A geoexchange heat pump works in conjunction with other distribution systems to regulate the temperature in a residence. It can be harmonized with a forced air system or with radiant floors. The energy from the ground can also be used to preheat your hot water tank.
Superior energy efficiency
Energy stored in the ground is available and accessible. By recovering it, you can considerably reduce your home’s energy consumption. This makes geoexchange the most efficient technology on the market.

Costs
Buying and installing a geoexchange heat pump does cost more than traditional heating and air conditioning systems. The cost is dependent on a number of factors: size of the residence, length of pipes to be installed, depth of digging, etc.
However, a geoexchange heat pump consumes about 60% less energy than electric baseboard heating systems. So in most cases, the investment pays for itself within 15 years, even without grants.
