What Impact Will New Furnace Efficiency Standard Have in 2023 and Beyond

March 02, 2023

Where you aware that more than half of your home’s energy costs are linked to heating and cooling? This is 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, measures how effective your furnace is at changing natural gas into heat. An 80 AFUE rating means your furnace will expend about 20% of the fuel it uses while creating heat.

In 2022, President Biden offered new energy-efficiency standards for residential gas furnaces that would greatly lower emissions, save customers money and stimulate sustainability.

This proposal is expected to:

  • Save Americans $1.9 billion annually.
  • Reduce 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 suggested rule would require all new gas furnaces to be 95 AFUE. This means furnaces would change 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 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 Troy soon, highly energy-efficient furnaces are ready and available. See how these furnaces can help you save on energy bills now.

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 reduces the amount of energy wasted, increases energy efficiency and lowers carbon-monoxide emissions. It also involves less natural gas to create the same amount of heat in comparison 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 that the former uses a secondary heat exchanger to capture any wasted heat from its exhaust gases, while the latter does not.

Equipment Lifespan

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 sufficient maintenance and regular service. If your heating system doesn’t have regular furnace maintenance, the unit may have a significantly shorter life span.

Why Condensing Furnaces Require a Higher Investment

Typically, condensing furnaces are more costly than non-condensing furnaces. This is the result of their increased efficiency and the extra hardware required to capture any wasted heat from its exhaust gases. The extra energy savings can often counterbalance the cost of purchase, however, so long term, it may be worth investing in a condensing furnace.

Guide to Variable-Speed Furnaces

Variable-Speed Furnaces: What Are They and How Do They Operate

A variable-speed furnace can adjust its fan speed based on the heating needs of your [[location]] home. It performs at a slower speed until it detects a temperature decrease and then increases speed up to supply more heat. This type of system is significantly more efficient than conventional furnaces, as it only utilizes the amount of energy necessary to heat your home, and thus, saves you money 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. To allow 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 stay on all the time. In fact, it runs at different speeds based on the temperature in your [[location]] home and the amount of energy it needs to sustain that temperature.

When too much energy is essential to maintain your chosen temperature level, the furnace will increase to a higher speed in order to keep up with demand. This allows for 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

As the name suggests, a furnace with two levels of operating (low or high) is called a two-stage furnace. On the low stage, the furnace performs at a reduced capacity as a way to maintain a chosen temperature in your home more efficiently. During the high stage, the furnace will run at maximum capacity to meet demands for greater warmth or cooling. With a two-stage furnace, you can realize improved energy efficiency and consistent temperatures throughout your home.

While two-stage furnaces are exceptionally efficient, not all models are condensing furnaces.

Does a Two-Stage Furnace Run All the Time?

A two-stage furnace won’t run all the time. In the low stage of operation, the furnace performs at diminished capacity in order to maintain a planned temperature more efficiently within your home. When a greater demand for warmth or cooling is needed, the unit will flip to its high stage and operate at full capacity. As such, two-stage furnaces are capable 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 functionality, low and high. During the low stage, the furnace works at reduced capacity to help uphold a desired temperature within your home. When a greater demand for warmth or cooling is desired, the furnace will shift to its high stage and operate at full capacity.

Variable-speed furnaces can operate at a variety of speeds in order to uphold a desired temperature more accurately within your home. So, if you have more options for temperature-settings, you also have more flexibility for heating you home, which also means more savings on energy bills.

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 translates to higher energy bills because the furnace will be on at all times 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 additional warmth or cooling is desired, the furnace will switch to its high stage and operate at maximum capacity.
