A & A Air Services works side by side with Somerset Well Drilling to complete all Geothermal projects. From big to small, A & A Air Services can handle it all. Because we specialize in Geothermal, we have state of the art equipment, and installers to ensure that the jobs are completed in a professional and timely matter.  A & A Air Services is also a top installer of Custom Radiant Floor Heating Systems. This can be used in conjunction with a WaterFurnace geothermal system.


How does Geothermal heating and cooling system work?

  • Outdoor Temperatures fluctuate with the changing seasons but underground temperatures don’t. Four to six feet below the earth’s surface, temperatures remain relatively constant year-round. A geothermal system, capitalizes on these constant temperatures to provide “free” energy. In winter, a series of fluid fills underground pipes called “loops” absorbs stored heat and carries it indoors. The indoor unit¬† compresses the heat to a higher temperature and distributes it throughout the building. In the summer, the system reverses, pulling heat from the building, carrying it through the loops and depositing it into the cooler earth.

Why is geothermal different from your ordinary heating system?

  • Geothermal doesn’t burn fossil fuel to generate heat, it simply transfers heat from the earth to provide a more efficient, affordable and environmentally friendly method of heating and cooling. Typically a small amount of electricity is used to operate the geothermal unit’s fan, compressor and pump. Geothermal consists of a geothermal unit, a loop field and duct work.

Efficiency of Geothermal:

  • Geothermal is over 5 times more efficient in the heating mode and more than twice as efficient in the cooling mode compared to the most efficient ordinary system. Because of the way geothermal operates, it provides four to five units of energy for every one unit of power used.

Benefits Of Geothermal:

  • Lower operating cost: Compared to conventional heating and air conditioning systems. Homeowners realize savings of up to 60% in the heating mode.
  • Safe: Geothermal requires NO natural gas, propane or oil to operate, which means there is no combustion, flames or fumes.
  • Clean: Because geothermal has no fumes, there is a higher level of indoor air quality when compared to a gas furnace.
  • Quiet: Unlike conventional heating and air conditioning units there is no noisy outdoor unit to disturb your outdoor environment. Waterfurnace geothermal units are designed for “whisper quiet” operation, similar to your refrigerator.
  • Reliable: Unlike conventional heating and air conditioning units, geothermal units are installed indoors, so they are not subject to wear and tear caused by rain, snow ice, salt air and debris. Geothermal units are proven to be very reliable and require less maintenance.
  • Flexible: Geothermal systems are installed in homes from the cold climate of northern Canada and Alaska to the heat of Florida and Texas. Whether your home is new or old, large or small a geothermal system will deliver the level of heating and cooling that your family needs. Geothermal systems can be installed in virtually any application by a certified licensed heating and air conditioning specialist.

State and Federal Grants for Geothermal Installations

  • Delaware: Delmarva Power and Delaware Electric Co-Op offer a grant up to $5000.00 (depending on tonnage) for a qualifying geothermal system.
  • Maryland: The Maryland Energy Administration offers a grant up to $3000.00 for a qualifying geothermal system. Delmarva Power in Maryland offers a $500 rebate for geothermal installations.
  • The Federal Government is offering a 30% Federal Tax Credit on the total cost of installation of a qualifying Geothermal System.
