GEOTHERMAL HEAT PUMPS
Below ground is a secure, renewable source of energy. Why not reap the rewards of an asset you already own through a geothermal heat pump system?
The EPA states, “Geothermal heating systems have the lowest life-cycle cost of all heating and cooling systems available”.
How They Work:
Geothermal heat pump systems, also known as ground source heat pumps, use heat from the largest solar collector in the world, the Earth itself!
Using advanced geothermal technology, we tap into the earth's natural heating and cooling properties through an underground loop system to consistently and evenly distribute warm air or cool air throughout your home every season of the year.
Why Choose a Geothermal Heat Pump System?
- They last longer than traditional heat pumps: Geothermal Heat Pumps tie into existing duct work like a traditional heat pump, but last longer as they have no outside exposure
- Highly Efficient, No Carbon Emissions:
Winter - A geothermal system extracts heat from the earth. The process is highly efficient, self-contained and produces no carbon emissions.
Summer - heat is extracted from the house and deposited in the ground, with even greater efficiency, using the same equipment.
- Savings: Significant monthly returns are realized upon installation of a geothermal system, particularly for larger homes and homes that heat with oil, propane, and natural gas. The chart below shows the average reallocation of heating and cooling loads after conversion to a geothermal system.
Geothermal systems provide clients with up to 75% savings over traditional heating means, and add up to 40% savings on hot water costs.
The system consists of a geothermal heat pump unit inside your home which would be roughly the size of your existing furnace and a series of pipes buried underground on your property.
Our geothermal specialist are skilled in selecting and installing the geothermal loop system best suited for your home or business regardless of the weather and soil conditions in your area.
Horizontal loops are the most common type of loop system, and are commonly used in rural areas due to the land space needed for installation. An excavator will dig several trenches about six feet deep in the ground, each one up to 300 feet long. Our green geothermal pipe is placed in the trenches which are then backfilled with soil.
Vertical loops are primarily used in urban areas because they require little land space for installation. A specially designed geothermal drilling rig bores vertical holes into the ground each ranging from 180 to 540 feet deep. Our green geothermal pipe is inserted into each vertical bore and then the holes are filled with bentonite grout.
Pond or Lake Loop
On properties that have a nearby lake or pond that is appropriate in size and eight feet deep, a loop system can be submerged at the bottom of the body of water. A single trench is excavated from the home to the water and typically two pipes are inserted into it. These two pipes connect to several green geothermal pipes that are submerged at the bottom of the lake or pond.
Open loops are most commonly used on rural properties that have existing high capacity water wells. Ground water is withdrawn from an aquifer through a supply well and pumped into the heat pump, while discharged water from the heat pump is redirected into a second well and back into the same aquifer.

Don’t take our word for it.... This is what our customers say!
“It’s been a great winter; I’ve been burning wood for 30 years, what a break it is to finally not have to haul. It’s so economical! I’m spending less on power, than what I would have on wood. It even draws enough heat at -24C, without turning on the auxiliary heat. The Previous winter, we were away 3 weeks and our power bill was $475.00, this year we were away for 6 weeks our bill was $180.00... for 6 weeks! You shouldn’t be able to build a house today without a heat pump or a geothermal system.”
