With the weather only set to get colder over the next few months, an efficient and effective furnace doesn't just keep people comfortable, but safe. However, because these systems are often expected to work overtime in the winter, they are also at increased risk of a malfunction or breakdown. The guide below lists signs that your heater needs replaced.

How to Know If Your Furnace Is Nearing the End

1. Old Age

A typical furnace runs for 15 to 20 years, so any major problems that occur in that interval mean that no amount of repair work is likely to save it. Be on the lookout for signs of aging, including never reaching the desired temperatures or loud noises. In the latter case, it's likely that an internal part, such as the heat exchanger, or blower, has degraded.

2. Dust Everywhere

If you’re reasonably diligent about cleaning your home, it may be surprising to find many surfaces still coated with dust. The culprit is often a decaying furnace. The heating system is meant to filter particles from the air before warming it up. However, if you've remembered to clean out your filter every month or two, and your family members are still sneezing and coughing from dust, it usually means the blower fan is no longer up to the task. 

3. Yellow Flame

The color of the furnace’s burner flame is another useful indicator of the heating system’s health. It should always be blue, but if it turns yellow, your unit may be generating carbon monoxide. That tends to happen as furnaces get older and break down; however, it can pose a severe risk to your family's health.
