5 Signs Your Furnace Has Reached the End of Its Lifespan

A home furnace can last for a long time, but it does not last forever. Instead of dealing with subpar heating in your home, learn how to recognize the end of life for your furnace. Early recognition will prevent the need for emergency services and will ensure you have proper heat to get through the whole winter.

You do not need to be an HVAC technician to recognize some of the more common end-of-life signs. When you notice one or more of the signs, you have the opportunity to look into furnace replacement options. Check out some of the signs to be aware of.



On average, a furnace can last around 20 to 30 years. While you may not celebrate the furnace's birthday each year, you have some easy ways to find out the age. The first is to look for visual clues around a furnace.



HVAC technicians may write the installation date on a furnace label or on a wall next to the furnace. If nothing is there, then check the furnace manual to see if it has the installation date. One of the last options is to look for the model number. When you search for the model number online, you can often find the year the furnace was originally manufactured.

If your home feels like a biosphere with different climates, then this could be due to poor performance from a furnace. As a furnace reaches end of life, the output of heat may not be consistent in homes. Door and window drafts can make a difference in heating, but when those differences are really dramatic from room to room, the furnace is typically to blame.

In many homes, you can hear exactly when a furnace turns on. During the winter, you may notice the furnace turns on more frequently than it should. When a furnace is near end of life and cannot provide the same heat efficiency, its ends up working harder to supply less heat.



Not only is the constant operation of the furnace distracting but can create a large increase in heating bills. If you feel like the furnace turns on often, keep track for a couple of hours and report your findings to an HVAC technician for further evaluation.

Repairs and maintenance are essential for keeping a furnace running strong, but at some point, you have to learn when to toss in the towel. If you constantly have to repair your furnace, then you may have to switch your heat investment. Instead of paying for more repairs, consider a full furnace replacement instead.



The figurative bandages to keep the furnace running will only last so long, and a replacement will ensure your furnace operates smoothly. A new furnace may also include warranty coverage to take care of any repairs in the future.The body content of your post goes here.

When people age, some of the more common signs are grey hair and wrinkles. When a furnace ages, visually signs are often present with rust and corrosion. Use a flashlight to physically examine the furnace, including the outer case, inlet pipes, and areas behind the furnace. Rust and corrosion will only spread within the furnace and create more problems.

If you see major signs of rust, you may want to dispose of the whole furnace and find a new replacement that has no rust issues.
