What Is A Good Efficiency Rating For A Furnace

In addition although the fleet efficiency of one brand might exceed that of another this does not necessarily indicate that any particular model of furnace marketed under the first brand out performs.

What is a good efficiency rating for a furnace.

You can identify low efficiency furnaces by the use of a continuous pilot light. This premier furnace boasts an efficiency rating of up to 99 that means it essentially converts every last bit of energy it uses into heating the home. Its top of the line models are as good as it gets. Precise comfort technology allows the furnace to keep the temperature held exactly where you want it.

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. The lowest efficiency allowed by law for new gas furnaces is 78 percent and some new models achieve 97 percent near total efficiency. Lennox slp99v variable capacity gas furnace series. Unfortunately older systems may not have a rating or the information may have been removed.

Why we chose it efficiency. Most new furnaces display an annual fuel utilization efficiency afue rating which is a measure of fuel efficiency. This is the ratio of the cooling output of an air conditioner over a typical cooling season divided by the energy it uses in watt hours. While some homeowners prefer to install a furnace with standard afue rating to save money on initial furnace replacement costs it s often a good idea to opt for higher energy efficient brands if your budget allows.
