When Should You Replace Your Furnace?

It’s always a big decision for a homeowner whether to repair or replace a heating system. Certainly, we cannot generalize all furnaces with the same answer. Here are some tips that might help you decide when to replace your furnace. Various signs indicate that it is time to replace your old furnace with an energy-efficient one, such as sudden temperature changes, high operating costs, and loud noises.

Signs Your Furnace Needs To Be Replaced

  • Unusual noises while it is operating at standard levels: Various noises may signal that your old furnace needs to be repaired or replaced. Noises like rattling, popping, humming, or screeching indicates that it is time to get your furnace replaced.
  • The temperature fluctuates in the house: Having sudden temperature changes within a single room or house is a clear sign that you should hire a licensed contractor to perform the repair. However, noticeable temperature shifts may indicate that a new furnace needs to be researched. The efficiency of old furnaces that are over 15 years old drops gradually, and their ability to distribute heat evenly decreases over time.
  • Heating repair costs and high utility bills: It is harder for a furnace to evenly distribute heat in your home when it has reached its peak lifespan of 15 years. The energy bill will spike each month dramatically due to this. Consider the total cost of your next repair when deciding when a furnace replacement is necessary. Whenever the cost of repairing your system exceeds that of putting in a new furnace, the system needs to be replaced.
  • A layer of soot is building up near the registers of the furnace: If your ventilation is inadequate, you may have soot or dust lingering in your bathroom, kitchen, or bedroom. Dry air caused by smoke and dust can damage wood flooring, couches, chairs, and shelves. When plants die, the air within the house is low on moisture. An old furnace that produces a lot of carbon dioxide will produce excessive dust and soot throughout the house.

Soot buildup is often seen near furnace vents and grilles. A register is an air duct cover that regulates airflow. If dirt or soot surrounds the furnace registers, there is likely something wrong, and it may be time to replace your furnace.

  • A yellow flame instead of a blue flame appears in a furnace: When your furnace is new and efficient, the flame will be pure blue in color. Your old furnace may be producing carbon monoxide if the flames coming from the burners are yellow. An improper combustion process may also cause yellow flames or a gas leak.
