When it comes to selecting a new furnace, many homeowners fall victim to common misconceptions about efficiency ratings and performance. At Paradigm Plumbing, Heating & AC, we regularly encounter customers who are confused about what these numbers really mean.

The Big Myth: Higher AFUE Always Means Lower Bills

One of the most persistent myths we encounter is that simply installing a furnace with the highest AFUE (Annual Fuel Utilization Efficiency) rating will automatically result in the lowest possible heating bills. While AFUE is important, it’s just one piece of the puzzle.

Here’s what really matters:

  • Proper system sizing for your home
  • Quality of installation
  • Home insulation levels
  • Ductwork condition and design

The Real Story

A 95% AFUE furnace installed in a poorly insulated home with leaky ductwork might actually cost more to operate than a 90% AFUE unit in a well-insulated home with sealed ducts. The key is looking at your heating system as part of a whole-home approach.

What This Means For You

Before investing in a furnace replacement, consider these factors:

  • Have your home’s insulation evaluated
  • Request a ductwork inspection
  • Consider a comprehensive home energy audit
  • Factor in local climate conditions

At Paradigm Plumbing, we believe in providing honest, practical advice about heating systems. While high-efficiency furnaces are excellent investments, they’re most effective when installed as part of a holistic approach to home comfort and energy efficiency.

Remember: The most efficient heating system is one that’s properly sized, expertly installed, and regularly maintained. Don’t let misleading myths about efficiency ratings lead you to overlook these crucial factors in your heating system’s performance.
