What A High Efficiency Furnace Really Means

Doing a little research on furnaces? Planning on buying a new one in the near future? 

You’ve probably noticed a lot of them claiming to be high efficiency. But what does that really mean? 

Every furnace on the marketplace today is more efficient than the models available even just a few short years ago. They’re built using today’s knowledge and technology; of course, they’re going to be more efficient and better built. 

What A High Efficiency Furnace Really Means

Still, there are differences. You can easily find some that claim certain characteristics, while others list different benefits. How do you know what’s best?

A high efficiency furnace typically does two things well:

  • It extracts more heat out of the combustion process
  • It uses less energy to get the job done

Those two things are what manufacturers work at to build better HVAC equipment. It’s what sets today’s model apart from those from just a few years ago. 

Today’s high efficiency furnaces will have:

Electronic ignition – no more pilot lights common in older furnaces. This electronic ignition keeps the furnace ready at all times. 

Multi-stage heating – high efficiency means producing lower heat levels when it’s mild outside, and higher heat levels when the temperatures continue to fall. 

Variable speed blower – this allows your furnace to operate at different capacities, depending on how much airflow is needed. 

Sealed combustion – high efficiency furnaces draw in air from outside in order to conserve energy rather than leaving the unit open and influenced by indoor air quality. This also improves safety levels.
