Question

Furnace efficiency is measured by

O a. Energy Efficiency Ratio (EER).
b. Annual Fuel Utilization Efficiency
(AFUE).
O c. Heating Seasonal Performance
Factor (HSPF).
d. Season Energy Efficiency Ratio

Answer 1

Furnace efficiency is measured by the Annual Fuel Utilization Efficiency (AFUE).

Step-by-step explanation:

Furnace efficiency is measured by the Annual Fuel Utilization Efficiency (AFUE). AFUE is a measure of the amount of fuel that is converted into usable heat by a furnace over an entire heating season, represented as a percentage. A higher AFUE rating indicates a more efficient furnace.
