How Furnace Efficiency Standards Will Change in 2023

March 02, 2023

Where you aware that more than 50% of your home’s energy costs are associated to heating and cooling? That is the reason why it’s critical 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 creating heat.

In 2022, President Biden recommended new energy-efficiency standards for residential gas furnaces that would substantially decrease emissions, save users money and stimulate sustainability.

This proposal is expected 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 mandate all new gas furnaces to be 95 AFUE. This means furnaces would convert nearly all the gas they use into heat.

So, what does all of this mean for your existing furnace in 2023? For the time being, not much, as the proposed rule wouldn’t go into effect until 2029 at the earliest and does not affect furnaces that are already in use.

But if you’re going to be needing furnace replacement in Thedford soon, highly energy-efficient furnaces are ready and available. Discover 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 capture wasted heat from the furnace's exhaust gases. This curbs the amount of energy wasted, increases energy efficiency and lowers greenhouse gas emissions. It also involves less natural gas to generate the same rate of heat 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 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 varies on the brand, model and other factors. In most cases, a condensing furnace should last between 10-20 years with appropriate 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 Are More Expensive

Typically, condensing furnaces are more expensive than non-condensing furnaces. This is because of their increased efficiency and the extra components required to capture any wasted heat from its exhaust gases. The additional energy savings can frequently counterbalance the price of purchase, however, so in the long run, it may be worthwhile 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 adjust its fan speed based on the heating needs of your [[location]] home. It runs at a slower speed until it detects a temperature decrease and then ramps up to produce 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.

The majority of 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 Continuously?

A variable-speed furnace doesn’t operate all the time. Instead, 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 essential to maintain your chosen temperature level, the furnace will increase to a higher speed to handle the 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 in order to maintain a chosen temperature inside your home more efficiently. During the high stage, the furnace will operate at full capacity to fulfill demands for increased warmth or cooling. With a two-stage furnace, you can realize much better energy efficiency and uniform temperatures throughout your home.

While two-stage furnaces are highly efficient, not all versions are condensing furnaces.

Does a Two-Stage Furnace Operate All the Time?

A two-stage furnace should not run constantly. In the low stage of operation, the furnace performs at reduced capacity in order to maintain a desired temperature more efficiently within your home. When additional warmth or cooling is needed, the unit will flip to its high stage and operate at full capacity. For this reason, two-stage furnaces are able to help reduce energy costs as it is not operating constantly.

Differences Between Two-Stage and Variable-Speed Furnaces

Two-stage furnaces have two stages of operation, low and high. During the low stage, the furnace runs at reduced capacity to help uphold a desired temperature within your home. When more warmth or cooling is necessary, the furnace will switch to its high stage and operate at peak capacity.

Variable-speed furnaces can work at several speeds in order to keep a precise 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. This means that the furnace will always run in order to maintain a desired temperature 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 desired, the furnace will shift to its high stage and operate at peak capacity.
