How Furnace Efficiency Standards Will Change in 2023

March 02, 2023

Would you believe more than 50% of your home’s energy costs are linked to heating and cooling? That is the reason why it’s essential to have an energy-efficient HVAC system.

Furnace efficiency standards were last revised to 80 AFUE in 2015. AFUE, or annualized fuel utilization efficiency, measures how effective your furnace is at turning 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, the Biden Administration recommended new energy-efficiency standards for residential gas furnaces that would greatly lower emissions, save users money and promote sustainability.

This solution is anticipated 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 30 years, 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 convert nearly all the gas they use into heat.

With these facts in mind, you may be asking yourself "what happens to my existing furnace"? For the time being, not much, as the proposed rule won't 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 Zelienople soon, highly energy-efficient furnaces are now available. Discover how these furnaces can save dollars each month off your energy bills.

Guide to Condensing Furnaces

How Condensing Furnaces Work

A condensing furnace is a kind of heating system that uses a secondary heat exchanger to capture wasted heat from the furnace's exhaust gases. This reduces the volume of energy wasted, enhances energy efficiency and lowers carbon-monoxide emissions. It also requires less natural gas to generate the same amount of heat compared 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 the condensing option's use of a secondary heat exchanger to collect 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. Usually, a condensing furnace is likely to last between 10-20 years with appropriate maintenance and regular service. If your heating system doesn’t have regular furnace maintenance, it may not last as long.

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 additional components necessary to capture any wasted heat from its exhaust gases. The extra energy savings can often counterbalance the price of purchase, however, so over time, 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 regulate its fan speed subject to the heating needs of your [[location]] home. It operates at a slower speed until it detects a temperature decrease and then fires up to provide more heat. This type of system is significantly more efficient than traditional 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.

Many of the 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. In fact, it runs at different speeds based on the temperature in your [[location]] home and the amount of energy it needs to keep that temperature.

When too much energy is necessary to maintain your preferred temperature level, the furnace will increase to a higher speed to handle the demand. This allows for more efficient heating and cooling in your home while also offering 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 as a way to maintain a desired temperature inside your home more efficiently. During the high stage, the furnace will run full throttle to meet demands for greater warmth or cooling. With a two-stage furnace, you can realize improved energy efficiency and steady temperatures in all areas of your home.

While two-stage furnaces are extremely efficient, not all models 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 runs at reduced capacity in order to sustain a planned temperature more efficiently within your home. When a greater demand for warmth or cooling is needed, the heating system will flip to its high stage and run at full capacity. As a result, 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 runs at reduced capacity in order to maintain a desired level of comfort within your home. When more warmth or cooling is necessary, the furnace will switch to its high stage and operate at maximum capacity.

Variable-speed furnaces can work at multiple speeds in order to maintain a more accurate desired temperature 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 performance and operate either at full capacity or not at all. This translates to higher energy bills because the furnace will always run in order to maintain a desired comfort level 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 a greater demand for warmth or cooling is necessary, the furnace will change over to its high stage and operate at maximum capacity.
