Would you believe more than 50 percent of your home’s energy costs are associated to heating and cooling? This is why it’s essential to have an energy-efficient HVAC system.
Furnace efficiency standards were last updated to 80 AFUE in 2015. AFUE, or annualized fuel utilization efficiency, calculates how effective your furnace is at converting natural gas into heat. An 80 AFUE rating means your furnace will waste about 20% of the fuel it uses while generating heat.
In 2022, the Biden Administration recommended new energy-efficiency standards for residential gas furnaces that would substantially reduce emissions, save customers money and promote 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 recommended rule would demand all new gas furnaces to be 95 AFUE. This means furnaces would transform nearly all the gas they use into heat.
Considering these guidelines, you might be asking yourself what does that mean for my existing furnace? As of this writing, very little, 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 East Bernard soon, highly energy-efficient furnaces are ready and available. Learn 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 decreases the volume of energy wasted, enhances energy efficiency and lowers CO2 emissions. It also involves less natural gas to generate the same rate of heat when comparing it to other types of furnaces.
How Condensing Furnaces Differ from Non-Condensing Furnaces
The biggest difference between a condensing furnace and a non-condensing furnace is that the former uses a secondary heat exchanger to capture any wasted heat from its exhaust gases, while the latter does not.
The life span of a condensing furnace will depend on the brand, model and other factors. In most cases, a condensing furnace will last between 10-20 years with sufficient maintenance and regular service. If your heating system doesn’t have regular furnace maintenance, the unit may not last as long.
Why Condensing Furnaces Cost More
Typically, condensing furnaces are more pricey than non-condensing furnaces. This is because of their increased efficiency and the additional hardware necessary to capture any wasted heat from its exhaust gases. The added energy savings can usually counterbalance the price of purchase, however, so long term, it may be worth investing in a condensing furnace.
Guide to Variable-Speed Furnaces
Variable-Speed Furnaces: The What's and How's
A variable-speed furnace can regulate its fan speed based on the heating needs of your [[location]] home. It operates at a slower speed until it senses a temperature decrease and then increases speed up to provide more heat. This type of system is significantly more efficient than standard furnaces, as it only uses the amount of energy necessary to heat your home, which results in a net savings each month on your utility bill.
Most variable-speed furnaces are condensing furnaces, although some 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. Rather, it runs at different speeds according to the temperature in your [[location]] home and the amount of energy it needs to keep that temperature.
When too much energy is required to maintain your preferred temperature level, the furnace will shift up to a higher speed to manage that demand. When this happens, you can expect 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 within your home more efficiently. During the high stage, the furnace will operate at full capacity to satisfy demands for greater warmth or cooling. With a two-stage furnace, you can experience much better energy efficiency and consistent temperatures throughout your home.
While two-stage furnaces are extremely efficient, not all versions are condensing furnaces.
Does a Two-Stage Furnace Run All the Time?
A two-stage furnace does not continuously run. In the low stage of operation, the furnace performs at diminished capacity in order to retain a preferred temperature more efficiently within your home. When more warmth or cooling is needed, the furnace will switch to its high stage and run at full capacity. As such, two-stage furnaces are proven to help reduce energy costs as it is not operating continuously.
Comparing Two-Stage and Variable-Speed Furnaces
Two-stage furnaces have two stages of functionality, low and high. During the low stage, the furnace runs at reduced capacity to help uphold a desired temperature within your home. When a greater demand for warmth or cooling is necessary, the furnace will switch to its high stage and operate at peak capacity.
Variable-speed furnaces can operate at a variety of speeds in order to maintain a precise temperature 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 operation and operate either at full power or not at all. This translates to higher energy bills because the furnace will be on at all times in order to maintain a desired comfort level within your home.
Conversely, two-stage furnaces have two stages of operation, low and high. During 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 necessary, the furnace will switch to its high stage and operate at full capacity.
