Heating and cooling systems -- also called HVAC systems -- have come a long way in recent years. Advances in HVAC system design have produced many furnaces, air conditioners and humidifiers that can save energy and improve air quality. These advances can help lower energy bills and create a more comfortable environment.
Advanced Energy Efficiency
If you're looking to replace a furnace or other HVAC systems, look for one with a high efficiency rating. Many furnaces have energy efficiency ratings of 92 to 94 percent, a far cry from the 78 to 80 percent efficiency models common 10 years ago. There also are furnaces with advanced HVAC controls, such as built in humidifiers and air cleaners to improve the air moving through the home.
Many of these products fall under the government's Energy Star rating system, meaning they meet strict guidelines for energy efficiency. Energy Star air conditioners, for example, can help reduce energy costs by 30 percent when compared with models used 10 to 15 years ago.
The Importance of Air Flow
As you shop for HVAC systems, also pay attention to how duct work is connected, as any leaks in the ducts can affect the air moving through the system. Also consider any home repairs that can help boost energy efficiency--caulking, repairing or replacing windows and doors as needed.
The way you use energy also is important. Do you use a set back thermostat and try to ensure your temperatures are comfortable while still being energy efficient? Do you perform routine maintenance, such as inspecting and tightening all electrical connections that flow into the HVAC systems?
There have been many advances in HVAC controls and systems in recent years. By pairing new equipment with needed home maintenance, you can go a long way toward a more energy efficient and comfortable house. |
