Our whole home promise to you means that we will approach energy efficiency within your Durham home as a whole, and not only focus on a single aspect. This approach means that we will put together a comprehensive plan that will achieve the greatest possible improvement in energy conservation.

In homes or buildings with aging heating and air conditioning systems, most often the greatest efficiency gains can be made by updating these to more modern ENERGY STAR® High-SEER systems. Beyond that, there are several other ways to significantly improve your energy efficiency.

Insulation & Air Ducts

A great deal of conservation can be achieved by improving systems that help retain heat inside the home. The first of these is adequate insulation. Whether you opt to improve your insulation using traditional materials such as fiberglass, cellulose, or cotton; or the latest in expanding spray foam insulation, the savings achieved by not allowing the temperature to escape from inside your home will be significant.

Leaky air ducts are another common cause of energy loss. We can significantly improve their function by a completely sealing them, which will result in a more even temperature throughout your home.


Weatherization is the systematic process of protecting your building from the elements of weather like precipitation, wind and sunlight all the while reducing energy consumption and improving efficiency. Weatherization works hand-in-hand with insulation to help maintain a comfortable indoor temperature.

Radiant Barriers

There are three ways that heat can transfer from one environment to another: conduction, convection, and radiation. Insulation and weatherization address the first two. A radiant barrier is the most effective way to resolve the third. The barrier serves to reflect heat on one or both sides, preventing the transfer from indoors to outdoors or vice versa.

Window Replacements And Lighting

A building’s windows are often the greatest culprits for heat loss. Replacing windows to more modern and energy efficient ones will help greatly improve your home’s efficiency.

Traditional incandescent lights waste up to 90% of the electricity they consume. Coming up with more energy efficient lighting solutions is yet another great way to greatly improve your carbon footprint.

In this era of global warming and other environmental emergencies, there has never been a better time to take action to make your home or building more energy efficient. Call the experts at Green Horizon One Hour Heating & Air Conditioning® by dialing (919) 646-3639 to schedule your free energy efficiency consultation in Durham.
