Energy Efficient Gas Furnace

Most new furnaces display an annual fuel utilization efficiency afue rating which is a measure of fuel efficiency.

Energy efficient gas furnace. A standard efficiency furnace provides 80 annual fuel utilization efficiency afue. Trane 90 gas furnaces over 90 afue. Modulating gas heat and variable speed blower provide precise comfort quiet operating sounds and high energy savings. Preferred series variable speed gas furnaces experience outstanding wintertime comfort and energy savings from bryant preferred series gas furnaces.

The r98v s value comes from a modulating design and a variable speed blower. Fully communicating controls offer advanced diagnostics to exchange system information and to ensure optimal performance and efficiency. Furnaces have become more energy efficient over the years. The prestige series r98v rheem s most efficient gas furnace has an afue rating of up to 98 7 percent making it the most efficient model we came across during our research.

In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust. That means a full 90 of the fuel you pay for is converted into cozy heat you can use. High efficiency furnaces offer 90 or more afue. Trane 90 furnaces deliver at least 90 efficiency far exceeding the government minimum standard of 80 afue for new furnaces.

A gas furnace made in the early 1970s typically has an afue of about 65 percent. The lowest efficiency allowed by law for new gas furnaces. Almost all of the best high efficiency gas furnaces below have the added benefit of being listed on the energystar highest efficiency gas furnaces of 2020 selection. Upgrading your furnace or boiler from 56 to 90 efficiency in an average cold climate house will save 1 5 tons of carbon dioxide emissions each year if you heat with gas or 2 5 tons if you heat with oil.

These days 95 afue is a common rating among new gas powered furnaces. Our highest efficiency furnaces with our best comfort features. The ultra quiet performance and consistent airflow from these units can reduce hot and cold spots throughout the home. They also offer enhanced summer humidity control.

Energy efficiency upgrades and a new high efficiency heating system can often cut your fuel bills and your furnace s pollution output in half.
