Did you know that more than one-half of your home’s energy costs are needed for your heating and cooling? That’s why it’s critical to have an energy-efficient HVAC system.
Furnace efficiency standards were last revised to an Annual Fuel Utilization Efficiency (AFUE) rating of 80% in 2015. This rating system calculates how effective your furnace is at natural gas into heat. An AFUE rating of 80% means your furnace loses about 20% of the fuel it uses while generating heat.
In 2022, President Biden revealed new energy-efficiency standards for residential gas furnaces that would significantly lower emissions, save consumers money and stimulate sustainability.
These revised standards are estimated to:
- Save Americans $1.9 billion annually.
- Cut carbon emissions by 373 million metric tons and methane emissions by 5.1 million tons over three decades, the equivalent of what 61 million homes emit each year.
Starting in 2029, the updated rule would demand all new gas furnaces to feature AFUE ratings of 95%. This means furnaces would combust nearly 100% of the gas into usable heat.
Considering these guidelines, you might be asking yourself what does that mean for my existing furnace? As of now, not much, as the proposed rule won't go into effect until 2029 at the earliest and does not affect furnaces that are already in use.
But if you are considering furnace replacement in soon, highly energy-efficient furnaces are ready and available. Find out how these furnaces can save you money on your utility bills.
Guide to Condensing Furnaces
How Condensing Furnaces Work
A condensing furnace is a style of heating system that uses a secondary heat exchanger to capture wasted heat from the furnace's exhaust gases. This limits the quantity of energy wasted, enhances energy efficiency and lowers greenhouse gas emissions. It also demands less natural gas to create the same volume of heat when comparing one to other types of furnaces.
How Condensing Furnaces Differ from Non-Condensing Furnaces
The main difference between a condensing furnace and a non-condensing furnace is condensing models use a secondary heat exchanger to collect any wasted heat from its exhaust gases, while the latter does not.
How Long Condensing Furnaces Last
The life span of a condensing furnace is dependent on the brand, model and other factors. Usually, a condensing furnace is likely to last between 10-20 years with appropriate maintenance and regular service. If your heating system doesn’t have regular furnace maintenance, the equipment may not last as long.
Why Condensing Furnaces Require a Higher Investment
Usually, condensing furnaces enhanced precision is a lot more efficient than conventional furnaces, as it only uses the minimum amount of energy required to heat your home, resulting in more savings on your utility bill.
The majority of variable-speed furnaces are condensing furnaces, although a handful are available in non-condensing models with lower AFUE ratings. In order for a furnace to be classified as a condensing furnace, it must offer an AFUE rating of 90% or higher.
Do Variable-Speed Furnaces Run Constantly?
A variable-speed furnace doesn’t run all the time. Instead, it runs at different speeds based on the temperature in your Front Royal home as well as the amount of energy it needs to reach that temperature.
When sufficient energy is demanded to maintain your desired temperature level, the furnace will shift to a higher speed to manage the higher demand. Doing this will ensure more efficient heating in your home while also providing quieter operation.
Guide to Two-Stage Furnaces
Two-Stage Furnaces: What They Are and How They Work
A heating system with two settings of operating - high and low - is called a two-stage furnace. In the low stage, the furnace performs at a reduced capacity in order to maintain the preferred temperature in your home more efficiently. During the high stage, the furnace will instead operate at full capacity to meet demands for increased heat. With a two-stage furnace, you can enjoy enhanced energy efficiency and comfortable temperatures everywhere in your home.
While two-stage furnaces are exceptionally efficient, not all all types are condensing furnaces.
Does a Two-Stage Furnace Run All the Time?
A two-stage furnace should not run constantly. In the low stage of operation, the furnace performs at diminished capacity in order to maintain a desired temperature more efficiently within your home. When a greater demand for energy is needed to sustain the set temperature, the unit will switch to its high stage and operates at full capacity. Because of this, two-stage furnaces are proven to help reduce energy costs without operating continuously.
Contrasting Two-Stage and Variable-Speed Furnaces
Two-stage furnaces have two stages of functionality, low and high. During the low stage, the furnace performs at reduced capacity in order to sustain a desired temperature within your home. When a greater demand for warmth or cooling is desired, the furnace will switch to its high stage and operate at peak capacity.
Variable-speed furnaces, meanwhile, can run at multiple speeds in order to keep a more precise temperature at home. Such precise functionality can also help reduce energy costs, as it is not constantly running on full power like many two-stage furnaces do.
Differences Between One- and Two-Stage Furnaces
One-stage furnaces have a single stage of operation and operate either at full capacity or not at all. This translates to higher energy bills because the furnace runs constantly in order to maintain a desired comfort level at home.
Two-stage furnaces, on the other hand, have two stages of operation, low and high. During the low stage, the furnace runs at reduced capacity in order to maintain the desired temperature more efficiently. When a greater demand for warmth or cooling is needed, the furnace will change over to its high stage and operate at peak capacity.
