Most Efficient Furnace 2018

The energy star most efficient 2020.

Most efficient furnace 2018. The r98v s value comes from a modulating design and a variable speed blower. While trane boasts impressively high efficiency across its entire lineup of furnaces it s worth noting that ruud has two of the most state of the art models around with energy star naming the u97v and u98v two of its most efficient furnaces for 2018.

This is one of the more efficient single stage furnaces available. A mid efficiency furnace will have an 80 to 85 afue rating while a high energy efficient unit can get up to 90 to 97 afue rating. Unlike the two stage units this gas furnace along with many other rheem models is. The lowest efficiency allowed by law for new gas furnaces is 78 percent and some new models achieve 97 percent near total efficiency.

These furnaces are more affordable though don t offer quite the same climate control. Their modulating gas valves allow the furnaces to run anywhere from 40 to 100 capacity.
