Underground Heating and Cooling Systems

Temperature control systems that use the natural insulation of earth and soil are called Geothermal heating systems, and are constructed by burying the structure partly underground. This allows for an energy-efficient structure.

Uses
Geothermal temperature control is best suited for residential uses due to most houses' small amount of volume compared to its surface area. Using the ground as a natural insulator decreases the rate of leakage that often is a problem with small homes.

Insulation
The ground that surrounds an underground structure acts as a blanket in the winter, retaining heat very well, and as a cooler in the summer, shielding the structure from the sun.

Cost
The construction of homes that use underground heating and cooling is not particularly more expensive than conventional homes, as conventional homes would also typically be partly underground.

Savings
Underground heating and cooling saves money because less money needs to be invested into insulation upon construction, and more money is saved on energy bills as the temperature retention is usually higher than in conventional homes.

Conduits
With some specific geothermal designs, conduits are used along the perimeter of the house--also buried--that regulate air flow. These also help the dispersal of air of a desired temperature. Air Conditioning Repair Columbia

Tips to Compare Heating and Cooling Systems

Brands
Some name brands are more familiar than others are for furnaces and air conditioning units, such as Trane or Bryant. When comparing, look at how long a company has been in business, its track record in customer service, warranties offered, and repair issues. A website such as ConsumerSearch (see Resources) gives professional and consumer reports on the various heating and cooling systems. Knowing the likes and dislikes of other buyers can help guide you in making an informed decision on your purchase.

Efficiency
In choosing a heating and cooling system, buy one that is as energy efficient as possible within your budget. Energy Star (see Resources) can help you compare heating and cooling systems and determine which has the best efficiency in the size that you need for your home. A more efficient system means less energy use and lower heating and cooling costs for you. In the end, this could help pay for the cost of buying the heating and cooling system.

Costs
When looking at various models, make note of what they offer to compare them to different models in the same price range. One may be more expensive but provide more energy efficiency, paying for itself sooner. One model may be less expensive but have a higher rate of repair complaints from consumers. While the lowest price may look enticing, knowing what you're getting for that price is key.
