This style of furnace requires you to relight the pilot if it goes out.

The lowest efficiency allowed by law for new gas furnaces is 78 percent and some new models achieve 97 percent near total efficiency. Up to 97 3 afue energy star certified and state of the art modulating valves which increases efficiency even more. 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. You can identify low efficiency furnaces by the use of a continuous pilot light.

High efficiency furnaces offer 90 or more afue. Unfortunately older systems may not have a rating or the information may have been removed.

It may also be called a seasonal energy efficiency rating. The total price of a new furnace depends on the brand efficiency and installation costs. Precise comfort technology allows the furnace to keep the temperature held exactly where you want it. Most new furnaces display an annual fuel utilization efficiency afue rating which is a measure of fuel efficiency.

A standard efficiency furnace provides 80 annual fuel utilization efficiency afue. In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust.
