Residential Geothermal HVAC

Much like any standard heating and air conditioning system, a geothermal heat pump has many of the same components and characteristics, but without the high utility bills, drafty air and loud, obnoxious outdoor equipment. Installation, however, is a different story. When it comes to geothermal HVAC system installation in Maryland (or any other state for that matter), there may be some digging or drilling involved. Careful planning is required in order to install a geothermal system correctly, which is why it’s important to use a Maryland HVAC company experienced in such projects.

Residential Geothermal HVAC Installation

Standard duct work is run from your air-handling unit placed either in the attic or in the basement of your residence. Vertical or horizontal wells are then drilled outside of the home, and polyethylene piping is inserted into the holes or trenches. All the piping joints get fused together using hot irons and routed to the inside of the home near the actual geothermal unit. Piping then enters what is called a pumping station that pushes and pulls the water through the underground loop, as well as the refrigerant loop located in the equipment. The “closed loop” is then purged with a freeze-resistant water. A thermostat is connected and heat or cooling is produced upon demand.

Types of Residential Loops

The loop pipes that carry the water and antifreeze mixture underneath the ground can be arranged in different ways. First, you have an open-loop and a closed-loop systems. A closed-loop system is filled once and the water never leaves it. An open-loop system, on the other hand, has to be connected to a large water source, such as a well, in order to continuously draw the water to be used for heating and cooling.

Second, you have a vertical and a horizontal loop systems. They differ in the way the loops are buried underneath the ground. A vertical system is often preferred by homeowners due to its compact size. A pond loop is a variation of a horizontal loop, but instead of being buried, it’s submerged in a body of water. It works the same as the regular ground loop, but is less expensive to install.
