Geothermal Heating & Cooling installation and service
Need your geo serviced?
No problem. We have years of experience with geothermal. We have also been trained by Waterfurnace to expertly maintain and repair your unit. Contact us today for a repair, a service, or to set up a maintenance agreement. That’s where we come out once or twice a year to keep your unit running at peak efficiency.

Simply put, a geothermal unit is a heat pump that uses the fairly constant temperature of the ground to its advantage.
A standard heat pump sits outside, using the outdoor air temperature to heat or cool your home. A geothermal system is more efficient because it uses water that is pumped through a loop. If it is summer, the geothermal unit will pump heat from your house into the loop, where it is dissipated through the ground. If it is winter, then it pumps heat from the loop into your house. Since ground temperature is consistently about 50 degrees, the unit will not have to work as hard as a heat pump that is sitting outside in 10 degree weather. To provide even more efficiency, WaterFurnace Series 7 units come with variable speed compressors and fans, so the unit only works as hard as is necessary, reducing power consumption.
There are four types of geothermal loops to choose from. Confused? Don’t worry. We’ll help you choose which loop is best for your home.
A horizontal loop is placed within trenches. Although the depth of the loop can vary, we generally dig about 6 feet deep. The length of the loop greatly depends upon load (or house size), but a good size portion of open land is always needed. A horizontal loop is a good choice if you live in the country, especially since trenching is cheaper than drilling a well.
An open loop is the most efficient way to run your geothermal system. Water is pumped from a well through the geo unit, and then dumped into another well. It is important that your water source is fairly pure. If your water has a lot of impurities, the impurities will slowly destroy the equipment; either by corrosion or mineral deposits.
A vertical loop is the most common. A well is drilled to the required depth, then the loops are dropped down this well. This is less destructive to the lawn, and requires much less space than the horizontal loop.
So how does all of this save you money?
Geothermal’s efficiency source is two fold. First, the ground temperature below the frost line is relatively constant. 45-50 degrees fahrenheit. This temperature being a lot closer to our desired 72°F means the unit dosn’t have to work as hard to pump heat into or out of your home.
Second, dirt, oddly enough, is a better thermal conductor than air. Actually, air is a good insulator, not a good conductor of heat. The reason we use it to cool stuff off is because it’s around us. If we were fish, HVAC would be way more efficient. 😁 Don’t believe me? Unfortunelty, I can’t quantify the fish thing, but, per engineeringtoolbox.com, air, at sea level and at 77°F, has a thermal conductivity of around 0.0151 Btu/(h ft F). Dry earth is at around 0.867. Soil conditions will vary this amount, not to mention groundwater will greatly increase this number.
A geothermal system is a great way to provide in-floor radiant heat. If you are interested in the comfort that an in-floor radiant system provides, we would be happy to explain all of your options to you.
Now, if only there was some way to calculate the savings to show you how much you could actually save…… Wait, there is!

But, be careful who you get to install your geo system.
Unfortunately, some contractors will install geothermal units without being properly trained. While their upfront cost may be less than others, a poorly designed system will cost much more in the long run. We have been specially trained by Waterfurnace not only on loop installation, but on how to size a loop/unit to a house.
