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

March 02, 2023

Would you believe more than 50 percent of your home’s energy costs are related to heating and cooling? This is why it’s critical to have an energy-efficient HVAC system.

Furnace efficiency standards were last modified to 80 AFUE in 2015. AFUE, or annualized fuel utilization efficiency, calculates how effective your furnace is at changing natural gas into heat. An 80 AFUE rating means your furnace will lose about 20% of the fuel it uses while producing heat.

In 2022, the U.S. government proposed new energy-efficiency standards for residential gas furnaces that would significantly lower emissions, save consumers money and encourage sustainability.

This solution is projected 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 demand all new gas furnaces to be 95 AFUE. This means furnaces would change 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 now, not much, as the proposed rule will not 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 Branchville 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 kind of heating system that uses a secondary heat exchanger to collect wasted heat from the furnace's exhaust gases. This decreases the amount of energy wasted, enhances energy efficiency and lowers greenhouse gas emissions. It also involves 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 primary difference between a condensing furnace and a non-condensing furnace is the condensing option's use of a secondary heat exchanger to gather 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. 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, the equipment may not last as long.

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 required to capture any wasted heat from its exhaust gases. The additional energy savings can often counterbalance the price of purchase, however, so ultimately, 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 adjust its fan speed subject to the heating needs of your [[location]] home. It performs 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 conventional furnaces, as it only consumes the amount of energy required to heat your home, and thus, saves you money on your utility bill.

Most variable-speed furnaces are condensing furnaces, although some 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 Constantly?

A variable-speed furnace doesn’t operate 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 necessary to maintain your desired temperature level, the furnace will increase to a higher speed to manage that 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

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 runs at a reduced capacity as a way to maintain a preferred temperature in your home more efficiently. During the high stage, the furnace will run at maximum capacity to fulfill demands for increased warmth or cooling. With a two-stage furnace, you can realize enhanced energy efficiency and steady temperatures throughout your home.

While two-stage furnaces are very 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 runs at diminished capacity in order to maintain a preferred temperature more efficiently within your home. When additional warmth or cooling is needed, the unit will switch to its high stage and operate at full capacity. As a result, two-stage furnaces are capable to help reduce energy costs as it is not operating continuously.

Contrasting 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 in order to uphold 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 sustain 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. Consequently, the furnace will be on at all times 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. 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 shift to its high stage and operate at peak capacity.
