These Are the Most Efficient Furnaces During the Winter

Gas furnaces have come a long way. In the 1970s, the top Annual Fuel Utilization Efficiency (AFUE) rating was 65%. New models now achieve as high as an 97% AFUE rating, representing near-total efficiency. Some features that enable these modern furnaces to be highly energy efficient include variable-speed blowers, two-level heating capacity, and secondary heat exchangers. Listed below are some of the most efficient furnaces on the market.

Lennox SLP99V Series

Lennox is a leading manufacturer of gas furnaces. Its premier SLP99V furnace has an unrivaled 99% AFUE rating. That means it more or less converts all the energy it uses into heat for your home. The unit runs at variable speed, which minimizes the sound produced as it kicks on or off in your home.

Lennox SLP98V Series

The Signature SLP98V gas furnaces have AFUE ratings ranging from 97.4% to 98.7%. With modulating heating and variable speed blowers, these systems provide high energy savings, precise comfort, and quiet operating sounds.

Carrier 59MN7 Infinity Series

Carrier’s Infinity 98 Series furnaces achieve AFUE of 97.2% to 98.5%. Their modulating gas valve output ranges from 40% to 100% for precise comfort. The variable-speed blowers and inducer motors make the units run at lower and quieter speeds.

Ruud U98V Series

The furnaces in the U98V Series have efficiency ratings of 98.1% to 98.7%. Their modulating gas valve allows them to operate at 40% to 100% capacity. For full functionality, you should use these Ruud furnaces with the EcoNet Control Center.

While highly efficient furnaces cost more than similarly sized systems with lower AFUE ratings, you may recoup the extra cost with your energy savings over the lifetime of the furnaces.
