Did you know more than 50 percent of your home’s energy costs are related to heating and cooling? That’s why it’s so important to have an energy-efficient HVAC system.
Furnace efficiency standards were last updated to 80 AFUE in 2015. AFUE, or annualized fuel utilization efficiency, determines how effective your furnace is at transforming natural gas into heat. An 80 AFUE rating means your furnace will expend about 20% of the fuel it uses while producing heat.
In 2022, the Biden Administration proposed new energy-efficiency standards for residential gas furnaces that would substantially decrease emissions, save customers money and stimulate sustainability.
This proposal is projected to:
- Save Americans $1.9 billion annually.
- Cut down on 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 suggested rule would demand all new gas furnaces to be 95 AFUE. This means furnaces would transform nearly all the gas they use into heat.
With these facts in mind, you may be asking yourself "what happens to my existing furnace"? As of now, nothing, as the proposed rule will not go into effect until 2029 at the earliest and will not affect furnaces that are already in use.
But if you’re going to be needing furnace replacement in Macon soon, highly energy-efficient furnaces are now available. Discover how these furnaces can help you save on energy bills now.
Guide to Condensing Furnaces
How Condensing Furnaces Work
A condensing furnace is a kind of heating system that uses a secondary heat exchanger to capture wasted heat from the furnace's exhaust gases. This curbs the volume of energy wasted, enhances energy efficiency and lowers carbon-monoxide emissions. It also requires less natural gas to create the same rate of heat in comparison 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 the condensing option's use of a secondary heat exchanger to collect any wasted heat from its exhaust gases, while the latter does not.
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 proper maintenance and regular service. If your heating system doesn’t have regular furnace maintenance, it may struggle with performance and ultimately fail earlier than anticipated.
Why Condensing Furnaces Cost More
Typically, condensing furnaces are more expensive than non-condensing furnaces. This is because of their increased efficiency and the additional hardware needed to capture any wasted heat from its exhaust gases. The extra energy savings can usually balance out the price of purchase, however, so ultimately, it may be worth investing in a condensing furnace.
Guide to Variable-Speed Furnaces
Variable-Speed Furnaces: What They Are and How They Work
A variable-speed furnace can switch its fan speed dependent on the heating needs of your [[location]] home. It runs at a slower speed until it detects a temperature decrease and then fires up to supply more heat. This type of system is much more efficient than conventional furnaces, as it only utilizes the amount of energy needed to heat your home, which results in a net savings each month on your utility bill.
Many of the variable-speed furnaces are condensing furnaces, although a few are available in non-condensing models with lower AFUE ratings. In order for a furnace to be classified as a condensing furnace, it must be 90 AFUE or higher.
Do Variable-Speed Furnaces Run Constantly?
A variable-speed furnace doesn’t run all the time. In fact, it runs at different speeds according to the temperature in your [[location]] home and the amount of energy it needs to maintain that temperature.
When too much energy is needed to maintain your chosen temperature level, the furnace will shift up to a higher speed in order to keep up with demand. Doing this will ensure more efficient heating and cooling in your home while also providing quieter operation.
Guide to Two-Stage Furnaces
Two-Stage Furnaces: What They Are and How They Work
A two-stage furnace is a type of heating system that utilizes two different stages of operation — low and high. On the low stage, the furnace performs at a reduced capacity to help maintain a preferred temperature inside your home more efficiently. During the high stage, the furnace will operate at full capacity to meet demands for increased warmth or cooling. With a two-stage furnace, you can achieve enhanced energy efficiency and consistent temperatures in all areas of your home.
While two-stage furnaces are exceptionally efficient, not all versions are condensing furnaces.
Does a Two-Stage Furnace Function All the Time?
A two-stage furnace does not continuously run. In the low stage of operation, the furnace performs at reduced capacity in order to retain a preferred temperature more efficiently within your home. When more warmth or cooling is needed, the unit will switch to its high stage and run at full capacity. Because of this, two-stage furnaces are capable to help reduce energy costs as it is not operating continually.
Comparing Two-Stage and Variable-Speed Furnaces
Two-stage furnaces have two stages of operation, low and high. During the low stage, the furnace works at reduced capacity as a way to sustain a desired temperature within your home. When more warmth or cooling is necessary, the furnace will change over to its high stage and operate at full capacity.
Variable-speed furnaces can work at a variety of speeds in order to uphold a desired temperature more accurately within your home. As such, variable-speed furnaces offer greater savings on your utility bills, because it has more options in terms of functionality.
Differences Between One- and Two-Stage Furnaces
One-stage furnaces have a single stage of functioning and operate either at full capacity or not at all. In other words, the furnace will run constantly in order to maintain a desired level of comfort within your home.
Conversely, two-stage furnaces have two stages of operation, low and high. Within the the low stage, the furnace runs at reduced capacity in order to maintain a desired temperature more efficiently within your home. When a greater demand for warmth or cooling is needed, the furnace will change over to its high stage and operate at full capacity.
