Choose the furnace that best aligns with your priorities, whether it’s cost-efficiency, environmental concerns, or long-term savings.

Furnace Efficiency Ratings
Understanding furnace efficiency ratings is key to selecting the right heating system for your home. These ratings tell you how effectively a furnace converts fuel into heat, affecting both your environmental footprint and your utility bills.
Here’s a breakdown of what these ratings mean and how to use them to choose a furnace.
Annual Fuel Utilization Efficiency (AFUE)
The AFUE rating measures the percentage of fuel converted into usable heat over a typical heating season. For example, a furnace with an AFUE rating of 90% converts 90% of the fuel to heat, while the remaining 10% is lost through exhaust or leaks.
 
How Does It Affect You?
The higher the AFUE rating, the more efficient the furnace is. This efficiency can significantly reduce your fuel consumption and your heating bills. Additionally, higher efficiency often correlates with reduced emissions, making your home greener.
Understanding AFUE Ratings

80% AFUE: This rating is often found in older or basic models. While more affordable upfront, they are less efficient and cost more to operate than higher-rated units.
90% to 95% AFUE: Furnaces with these ratings are considered high-efficiency. They use advanced technology to reduce fuel waste and can save you money in the long run, especially in colder climates where the furnace runs frequently.
Above 95% AFUE: These are among the most efficient furnaces available. They use cutting-edge features like secondary heat exchangers and sealed combustion to achieve superior efficiency. Ideal for environmentally conscious homeowners and those in very cold regions.

Choosing the Right AFUE Rating for Your Home

Consider Your Climate: If you live in a colder area, investing in a higher AFUE rating can lead to more significant savings on heating bills.
Balance Initial Cost vs. Long-term Savings: Higher efficiency furnaces typically cost more upfront but can offer substantial savings over their lifespan. Calculate potential savings in fuel costs against the initial investment to find a cost-effective option.
Evaluate Environmental Impact: For those looking to minimize their carbon footprint, a furnace with a high AFUE rating will use less fuel and emit fewer greenhouse gases.
