Boost Your Home’s Green Power With Geothermal HVAC

Harnessing solar energy for your home is a great way to reduce your house’s carbon footprint. Solar panels are popping up on so many roofs it’s kind of become the norm. Solar energy is a trusted and reliable source of energy that powers your home. But what if there were another way to reduce your home’s carbon footprint even more in addition to solar energy? Good news, there is! Geothermal heating and air systems are a fantastic compliment to solar panels taking a large chunk of energy required to heat and cool your home off the backs of your panels. Let’s explore.

The Basics

Geothermal HVAC is not to be confused with geothermal energy. The two systems perform on the same principal; drawing energy from the earth’s core temperature. Geothermal energy is converted into electricity that powers your home. But you’ve already got your solar panels installed, so this is not the geothermal droid you’re looking for. Geothermal HVAC, however, operates only on the purpose of heating and cooling your home, making it the perfect pair for your solar energy.

Roughly 4 to 6 feet below ground, the earth’s temperature stays in the perfect range of 68 – 72 degrees fahrenheit. This core temperature does not fluctuate beyond this range regardless of what the temperature is outside your door. For the purposes of regulating a houses temperature, technology takes advantage of this constant. A series of pipes are laid underground in the moderate temperature zone. The pipes are laid out to form a loop around the house. Some plans lay the pipes vertically, some lay them horizontally, and some include a well creating an open loop system. The water from the well is pulled up, passed through a heat exchanger where it’s raised or lowered to your desired temperature that then runs the loop of the house until it is reinjected back into the pump; and so the process goes in perpetuity.

Geothermal HVAC uses electricity to run the pump, but that’s it. The rest of the system runs independently and the earth’s temperature does the brunt of the work. There are no fossil fuels or chemicals used in any of the steps either.

The Benefits

What makes geothermal HVAC so much better than traditional heating and cooling systems comes down to logistics. Traditional systems have a unit outside the home that pulls in air from the outside and runs it through its complex system to convert hot air to cool and vice versa, depending on the season. Now think about it. If you live in a warmer climate, that means your AC unit is working incredibly hard to convert 100+ degree air down to 72 degrees. That’s a 30 degree conversion for months at a time. You surely see the spike in utilities during periods of extreme heat and cold.

This is why switching to geothermal HVAC is a no-brainer. Instead of that massive temperature conversion, this system only has to convert by a few degrees, meaning it doesn’t have to work as hard to regulate your home’s climate. Homeowner’s who have made the switch report a savings of half what they usually spend on heating and cooling their home.

The benefits don’t stop there, either. Maintenance for these systems is minimal. Water is used for the system, but aside from any repairs you may encounter, once the well is filled, the water doesn’t need replacing. On average, in a 10-15 year timespan you’ll only have a few repairs needed to the pump or heat exchange. And because all the work is happening underground, you’ll barely even notice when it kicks on to run, it’s that quiet. So while the price tag of this new system will run you up into the $10,000 – $15,000 range, with the savings you’ll see in your electricity bills geothermal HVAC pays for itself within a matter of years.
