Today, we\u2019re going to start from the bottom up\u2013we want to give you the necessary information to get a high-quality furnace.<\/span><\/p>\n

What’s the Difference Between an 80% and 95% Furnace?<\/span><\/h2>\n

Let\u2019s start off by defining the difference between an 80% efficiency furnace and a 95% efficiency furnace.\u00a0<\/span><\/p>\n

We want to start things off by mentioning the AFUE rating. The AFUE (or Annual Fuel Utilization Efficiency) rating is a tool used to measure a furnace\u2019s efficiency. If you have an 80% AFUE-rated furnace, it means 20% of the energy produced by natural gas is expelled as exhaust. While 80% AFUE-rated systems were more common in the past, there are systems with up to 95% AFUE ratings available today.<\/span><\/p>\n

This might be obvious, but a 95% AFUE-rated furnace is more efficient than an 80% system. For some people, it may initially seem that the choice between the two is obvious. You want a system that\u2019s more efficient, right?\u00a0<\/span><\/p>\n

The answer is actually: not always. The efficiency isn\u2019t the only thing that\u2019s different between these two systems. The way these two systems work is also vastly different. An 80% furnace vacuums in the air from the surrounding area to produce warmth. This is also known as open combustion. A 95% furnace sucks air in from the outdoors in a sealed combustion system. In certain circumstances, an 80% AFUE rated system might suit a home\u2019s needs better than a 95% AFUE rated system can.\u00a0<\/span><\/p>\n

Other Important Factors That Impact Furnace Efficiency<\/span><\/h2>\n

Your furnace\u2019s AFUE rating isn\u2019t the only thing that\u2019s going to factor into your furnace\u2019s efficiency. If efficiency is high on the list of things you want from your heater, then you should also consider the type of heater you\u2019re choosing regarding stages and speeds.<\/span><\/p>\n

For example, lots of homeowners choose single-stage furnaces. These systems only have one setting and that\u2019s on or off. When your heater is on, it runs on full blast. A two-stage furnace can offer you another stage. It\u2019s has on (100% capacity), a slow speed (65%), and off.\u00a0<\/span><\/p>\n

Now let\u2019s discuss modulation. A furnace with a modulated gas valve is similar to a two-stage furnace. It operates at a variety of capacities to match your fluctuating heating needs.\u00a0<\/span><\/p>\n

We say all this to say that there are no absolutes in furnace efficiency. A variable speed 80% AFUE rated furnace is likely to be more efficient than a single stage 95% AFUE rated furnace. This is why you should discuss your options with us.\u00a0<\/span><\/p>\n
