While modern furnaces are typically expensive, they are vastly more efficient than older heating systems such as boilers and heat pumps. The efficiency of a heating system is measured by its Annual Fuel Utilization Efficiency or AFUE. The AFUE indicates how much of the energy is converted to heat vs the energy lost because of combustion. Modern furnaces usually have a 90% AFUE and above.
When choosing what type of furnace to install in your home, you must understand what energy sources are available in your area. Seeking recommendations from a Colorado furnace repair technician is always the best option when your furnace needs replacing.
Not all furnaces are created equal and they each have pros and cons when it comes to efficiency. Here are several common furnace types to consider:
Natural Gas Furnaces
Considered the most common type of furnace used by Americans, natural gas furnaces are economical and energy-efficient. About 48% of U.S households use this type of furnace. It works by using natural gas to produce hot air that will result in temperature rise throughout the house. Gas furnaces usually last for about 25 years and require minimal home heating repair. Natural gas furnaces have an AFUE rating of 88% to 98% efficiency.
If natural gas is not available in your area, oil can be a good substitute. Oil furnaces are generally cheaper, but the fuel is less efficient than natural gas. Because it uses oil to convert heat, an oil furnace can produce deposits of soot on the surface, making it hard to clean and maintain. Oil furnaces are 80% to 90% efficient based on AFUE rating.
While purchasing an electric furnace is cheaper and more convenient to install and use, it is more costly in the long run because of its high energy consumption. Electric furnaces usually last about 10 years and have an efficiency of 95% to 100% AFUE rating.
In rural areas where electricity, oil, or gas are scarce, propane is often the best choice. Propane is contained in steel tanks and has storage stability. The newer generations of propane furnaces have 90% to 98.5% efficiency.
Most North Americans choose furnaces to warm their households. If you own one, you need to conduct maintenance to promote optimum heating performance. For all your Colorado furnace repair needs, contact Tri-City Heating & Air Conditioning, Inc. today! We also offer 24/7 emergency HVAC services.
