Where you aware that more than 50 percent of your home’s energy costs are linked to heating and cooling? That is the reason why it’s critical to have an energy-efficient HVAC system.
Furnace efficiency standards were last revised to 80 AFUE in 2015. AFUE, or annualized fuel utilization efficiency, determines how effective your furnace is at turning natural gas into heat. An 80 AFUE rating means your furnace will lose about 20% of the fuel it uses while creating heat.
In 2022, President Biden proposed new energy-efficiency standards for residential gas furnaces that would substantially decrease emissions, save users money and stimulate sustainability.
This proposal is anticipated to:
- Save Americans $1.9 billion annually.
- Lower carbon emissions by 373 million metric tons and methane emissions by 5.1 million tons over the next 25 - 30 years, the equivalent of what 61 million homes emit each year.
Starting in 2029, the proposed rule would require all new gas furnaces to be 95 AFUE. This means furnaces would convert 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 won't go into effect until 2029 at the earliest and doesn’t affect furnaces that are already in use.
But if you’re going to be needing furnace replacement in Laguna Niguel 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 type of heating system that uses a secondary heat exchanger to trap wasted heat from the furnace's exhaust gases. This reduces the amount of energy wasted, enhances energy efficiency and lowers carbon-monoxide emissions. It also involves less natural gas to produce the same rate of heat when compared to other types of furnaces.
How Condensing Furnaces Differ from Non-Condensing Furnaces
The primary difference between a condensing furnace and a non-condensing furnace is the condensing option's use of 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 depends on the brand, model and other factors. Generally speaking, a condensing furnace will last between 10-20 years with appropriate maintenance and regular service. If your heating system doesn’t have regular furnace maintenance, the equipment may have a significantly shorter life span.
Why Condensing Furnaces Are More Expensive
Usually, condensing furnaces are more costly than non-condensing furnaces. This is the result of their increased efficiency and the additional components essential to capture any wasted heat from its exhaust gases. The added energy savings can frequently counterbalance the expense 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 change its fan speed subject to the heating conditions of your [[location]] home. It performs at a slower speed until it senses a temperature decrease and then fires up to provide more heat. This type of system is much more efficient than standard furnaces, as it only utilizes the amount of energy needed to heat your home, saving you money in the long run.
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. Instead, it runs at different speeds based on the temperature in your [[location]] home and the amount of energy it requires to keep that temperature.
When too much energy is necessary 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. During the low stage, the furnace performs at a reduced capacity as a way to maintain a preferred temperature within your home more efficiently. During the high stage, the furnace will run full throttle to meet demands for additional warmth or cooling. With a two-stage furnace, you can realize enhanced energy efficiency and consistent temperatures in all areas of your home.
While two-stage furnaces are highly efficient, not all versions are condensing furnaces.
Does a Two-Stage Furnace Function 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 retain a preferred temperature more efficiently within your home. When additional warmth or cooling is needed, the unit will flip 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 constantly.
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 to help uphold a desired temperature within your home. When a greater demand for warmth or cooling is needed, the furnace will switch to its high stage and operate at full capacity.
Variable-speed furnaces can run at multiple speeds in order to maintain a more accurate desired temperature within your home. Through this ability it can also help reduce energy costs as it is not constantly running on full power like many two-stage furnaces are required to do.
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. As a result, the furnace will run constantly in order to maintain a desired level of comfort within your 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 a desired temperature more efficiently within your home. When additional warmth or cooling is needed, the furnace will switch to its high stage and operate at peak capacity.
