Having a furnace to provide your home with heat is an essential convenience needed to help you perform your daily activities in the midst of an unyielding winter.
However, furnaces are not made to last forever. Time will come when they will show a decline in performance and display signs that you need a replacement. It won’t be cost effective to continue using an inefficient furnace as it uses more fuel to keep your home warm. Also, an old furnace has a tendency to break down and a need for frequent repairs.
While it is true that buying a new furnace is a major piece of investment, it also plays an important part in letting your family live in a comfortable home environment. In addition, a new furnace is more economical to operate as it uses less energy and does a better job of providing consistent heat throughout your home.

This article highlights the Lennox Merit® Series ML180 Gas Furnace.
Should You Replace Your Furnace?
Depending on usage and how your unit is maintained, the average lifespan of a furnace is typically between 15 to 20 years. If your existing furnace is around that age, getting a new one might make more sense than trying to keep your old, inefficient unit.
Old furnaces tend to work harder to provide your home with the heat it needs. This often leads to overheating and the failure of certain parts. Furnaces pick up most breakdowns during the last two years of their lives. Another sign to watch out for is when you need to wait to get a replacement part. As your furnace gets older, finding replacement parts gets harder.
If you have to always adjust the thermostat because you feel that some rooms are warmer than others, you may need to look into getting your furnace replaced. That’s because older furnaces are unable to properly distribute the heated air throughout the home.
If your furnace is working properly, it should create a blue flame with only very little yellow at the tip of the flame’s inner core. If the flame is mostly yellow or orange, it may be a sign that it creates carbon monoxide. This suggests a major, potentially dangerous issue. Two possible causes of this problem are too much gas and not enough air. Either way, you need a professional to look into the problem and give you necessary recommendations.
