Geothermal Heating and Cooling Services for Franklin & Wake Counties

House With Underground Coils

Homeowners in Franklin and Wake Counties are always looking for more efficient ways to heat and cool their homes. Some of the most efficient and reliable systems on the market today are geothermal heating and cooling systems. If you're ready to take your home or business to the next level, the geothermal HVAC experts at Alford Mechanical can help.

How A Geothermal Heat Pump Works

Air-source heat pumps work by exchanging heat with the outside air. In the winter, the heat pump collects heat from the outside air and brings it into the building; in the summer, the system collects heat from inside and pumps it outside. These systems are fairly efficient in relatively mild weather, but they can run into problems on very hot or very cold days.

A geothermal heat pump uses the same cooling cycle, but instead of using the air, it uses an underground coil to exchange heat with the ground. Geothermal heating and cooling systems take advantage of the much more stable temperatures inside the Earth to keep your home at a steady temperature even on extremely hot or cold days.

Types of Geothermal Heating and Cooling Systems

There are three main types of geothermal systems, based on the shape of the underground loop.

  • Horizontal Loops: These loops are buried fairly shallowly and take up a fair amount of space, requiring a larger property. They are less expensive to install but can also be more sensitive to fluctuations in the outside temperature. Horizontal loops are usually preferred for residential projects.
  • Vertical Loops: The underground loop digs deep into the ground, taking up very little space on the surface level. Vertical loops are more expensive to install because of the amount of excavation needed, but they provide extremely efficient climate control. They are generally preferred for commercial projects and in urban areas.
  • Water-Source Loops: These types of loops can be used if you have a pond or other water feature on your property. They are potentially the most efficient of all, though this depends on the depth of the water.

Going Geothermal? Trust Alford Mechanical

Geothermal heating and cooling is a powerful long-term investment in your home. The above-ground components are built to last 25 years with minimal maintenance, and the underground loop is good for 50 years or more. To make sure that investment is a strong one, you need a trusted HVAC contractor to install the system.
