A working heat source is a necessity for the health and safety of the occupants in most homes, especially those in cold climates. For first-time homeowners, however, the responsibility to keep their furnace in good working order is easiest when they learn to recognize some common signs of potential repair issues that can lead to heating system failure and falling temperatures inside the living spaces of the home.
If you have just purchased your first house and would like to become better equipped to recognize the signs of potential repair issues arising within your heating system, these tips will offer you some helpful information.
Noisy fan operation
In both electric and gas furnaces, a fan that becomes increasingly noisy during its operation is providing an important signal that a repair issue may be forming. Common causes of fan noise include:
- warped or damaged fan blades
- excessively dirty blades that have become unbalanced
- worn or damaged bearings
- worn or damaged fan belts
Since a fully operational furnace fan is required to efficiently move heat throughout the home, it is important to pay attention to any fan noise and schedule appropriate repairs.
Ignition and flame issues
Gas furnaces, particularly those that are older or poorly maintained, may develop issues that can cause noticeable changes in the flame color and the speed at which ignition takes place. Healthy flames are typically blue in color or blue with a small tip of white or yellow. When gas jets and ignitions become clogged or damaged, the amount of blue may decrease while the amount of yellow increases.
Homeowners who note this type of color change or find that their furnace is taking longer than usual to ignite when cycling on should consider scheduling immediate repairs before the situation worsens.
In any case, homeowners who find that the flames of their gas furnace are yellow instead of blue may be experiencing a more serious situation. Yellow flames can mean that not all of the gas is being consumed by the fire, allowing a portion of it to remain in the home or allowing excess carbon monoxide to be released into the living spaces of the home.
In order to protect the occupants from exposure to high levels of carbon monoxide or dangerous gas fumes, it is a good idea to stop using the furnace, remove all occupants from the home, and schedule immediate heating repairs.
