As the years go by, we often notice that our furnaces don’t perform quite as well as they did when new. But do furnaces actually get less efficient with age, or is it simply a matter of perception? The short answer is yes—furnaces do become less efficient over time. Understanding why this happens and what signs to look for can help you know when it might be time for an upgrade.
Why Furnaces Lose Efficiency with Age
Over time, the internal components of a furnace experience wear and tear, which gradually impacts performance. Key parts like the heat exchanger, blower motor, and burners begin to wear down, making it harder for your furnace to produce and distribute heat effectively. As these parts age, they require more energy to operate, meaning they need more fuel to provide the same level of comfort they once did.
In addition, newer furnace models are designed with more advanced technology and higher energy efficiency ratings than older units. Even if your older furnace was efficient when it was first installed, it may no longer be competitive with current energy standards.
Signs Your Furnace Is Losing Efficiency
If your heating bills have steadily increased over the years, this can be a strong indicator that your furnace is losing efficiency. Other signs include frequent repairs, inconsistent heating, or longer running times to reach the desired temperature. These issues can mean your furnace is working harder than it used to, using up more energy and costing you more.
How Long Can You Expect Your Furnace to Last?
On average, furnaces last between 15 to 20 years. However, as they near the end of their lifespan, efficiency drops significantly. Regular air filter changes and routine maintenance by the pros can help extend the life of your furnace and slow down the loss of efficiency, but at a certain point, replacing it with a newer model can offer better performance and energy savings.
