Understanding Furnace Efficiency
Furnace efficiency affects the cost of heating your home and the comfort
of your living spaces. The efficiency of any heater is measured by its
AFUE, or Annual Fuel Utilization Efficiency. AFUE is a ratio of the efficiency
with which a furnace converts incoming energy into heat—a higher
AFUE rating means greater efficiency.
- Today, new combustion furnaces must have an AFUE of 78% or greater, but
older furnaces may have AFUE ratings as low as 65%. This is why it can
be extremely beneficial to consider upgrading an older furnace, even if
it appears to be working well. Even when it is functioning perfectly,
a furnace with an AFUE of 65% will always cost more to operate than a
new furnace with an AFUE of 78% or higher.
- To be classified as a high-efficiency furnace, a heater must have an AFUE
rating of 90% or higher. Currently, combustion furnaces are available
with AFUE ratings up to 98.5%, while electric furnaces can reach AFUE
ratings of 100%.
- Regardless of whether you specifically want a high-efficiency furnace,
purchasing a new furnace with the highest AFUE rating you can comfortably
afford will offer the greatest energy savings over the lifetime of the
furnace, which can range from 10-20 years with the right furnace maintenance

Fuel: It’s often easiest to purchase a new furnace that uses the same
fuel source as your old one. However, it’s also worth considering
the projected cost of fuel in the future; you may be able to save money
or improve efficiency by switching to another type of fuel.
Size: Furnaces are available in varying sizes and capacities. Choosing a furnace
that is neither too large nor too small for your home is the key to heating
your space effectively for greater comfort at lower cost.
