The energy efficiency of natural gas furnaces continues to improve as technology advances. Once, standard furnaces had an AFUE rating of 70, which means the furnace would convert 70% of its fuel source (natural gas) into direct heat, losing 30% to exhaust. Today, many standard furnaces have 85 AFUE, and special high-efficiency furnaces can score in the high 90s. That’s an enormous change in efficiency that can mean significant savings for a household over the winter.
If you’re considering a new furnace installation in Ellensburg, WA or elsewhere in our service area, we recommend you look into high-efficiency furnace models. They cost more than mid-efficiency furnaces, but the long-term savings will help these furnaces pay for themselves in a few years.
If you’re curious about what allows high-efficiency furnaces to use so much less power to do the same job, follow us below.
