Is a higher efficiency furnace always better? Back
If you live in a colder climate (frequent dips below 30 degrees) a high efficiency furnace is worth considering.
A 93% furnace consumes about 16% less gas than a standard 80% efficient furnace. However in warmer southern climates the limited operating time may not justify the price increase.
Another important consideration is installation and serviceability. 93% furnaces are more complex than standard efficiency furnaces and if they are not common in your climate the service technicians in your area may not be familiar with proper installation and service procedures.
Very moderate climates such as Florida, Texas, and Southern California will normally use standard 80% efficient furnaces.
If you live in a warmer area and desire the comfort and performance enhancing features offered by 2-stage, variable speed furnaces then consider one of our Ruud or Goodman standard efficiency 80% furnaces but select one of the variable speed, 2 stage models.
