Central Air Conditioning

Central AC is a cooling system that uses a refrigerant to absorb heat, making an area cooler. The central air conditioning unit cools and dehumidifies air before pushing it through a home's ductwork with a series of fans. These cooling units are typically combined with a furnace system.


  • The ductwork system used by a central air conditioning unit can also distribute heat from a furnace.
  • Works quickly to spread cool air through an entire home.
  • The filter used in a central AC system can remove pollutants and allergens from the air.


Air conditioners manufactured in the 1970's use 30-50% more energy than today's models. Efficiency of AC units is measured in SEER (seasonal energy efficiency ratio). Older systems typically have ratings of 6 SEER or less, while central air conditioning units made today must have a minimum of 13 SEER. The higher SEER rating, the more energy savings an AC unit will provide over the course of its lifetime.

Geothermal Cooling

Geothermal cooling uses a pump powered by an underground looped piping system. A hot refrigerant circulates in the loop where the ground absorbs the heat. The cooled refrigerant then reaches a ground-source pump where air is concentrated and sent through a home's ductwork. Geothermal ground pumps work by relying on the steady temperature of the earth at about 6 feet below ground.


  • Geothermal systems can also be used for heating and hot water.
  • With one of the highest efficiency rates of heating and cooling systems on the market today, geothermal cooling can lead to increased savings on utility bills.
  • Geothermal units are durable and reliable. Being underground keeps them protected even longer and makes them one of the quietest heating options.


Geothermal cooling creates cool air from renewable resources thus reducing dependency on expendable energy sources. Geothermal cooling systems save money in both operating and maintenance costs, and energy savings typically exceed initial investment in as little as three years.
