If you’re planning to upgrade your home’s HVAC equipment, understanding how to use the labels can help you compare different models and brands to find the most energy-efficient option.

Furnace efficiency is measured by AFUE, short for Annual Fuel Utilization Efficiency. It’s a simple percentage that gives consumers a basis to compare energy efficiency among similar makes and models of furnaces at a glance. AFUE isn’t the only element that impacts your efficiency and operating costs. Other factors include the airtightness of your home, the amount of insulation, and how many hours a day you typically run the furnace.
Heat exchanger, R-values, CFM and AFUE – what do all of these HVAC terms mean? Learning the terms and acronyms that heating and cooling professionals use will help you communicate better with your HVAC contractor and gain a better understanding about products and their efficiency.
There are many factors that contribute to the lifespan of gas furnaces, including the quality of the furnace, installation quality, how hard it works, and regular maintenance as per the manufacturer’s recommendations. On average, a furnace will last somewhere between 15 and 20 years. Unfortunately, many furnaces simply give out at the end of their lifespan without a great deal of warning. Therefore, if your gas furnace has passed the 15-year mark, it is a good idea to begin researching replacement options.
When it comes time to buy a new furnace, heat pump or air conditioner, it’s helpful to prioritize communicating with your HVAC contractor. Understanding a few common heating and cooling concepts will help you select the best type of equipment for your home and budget.
