Catching a malfunctioning furnace before it completely fails gives you the chance to repair or replace your furnace before you’re left in the cold. Here are five common signs of a malfunctioning furnace.
Higher-Than-Normal Heating Bills
If you have been using your furnace like usual but have noticed your monthly heating bills increasing substantially, a failing furnace may be to blame. Malfunctioning furnaces are less efficient at heating than normal, causing them to use more energy to maintain the same temperature.
Patches of Cold Air
If your furnace isn’t able to heat your home evenly and you are experiencing cold spots, a malfunctioning blower fan may be the cause. Your furnace’s blower fan is responsible for distributing warm air throughout your house, and an issue with the blower fan’s motor may leave it unable to perform correctly.
Pops, squeaks or other strange noises coming from your furnace can be a sign that some part within the unit has loosened or come off altogether. Addressing the issue may be as simple as tightening or replacing the loose part.
Dust Throughout Your Home
An increase in the amount of dust throughout your home can be a sign that your furnace’s filtration systems are breaking down. As part of the process to heat your home, your furnace pulls in dirty air from outside and filters it. Changing your furnace’s filters should be part of your quarterly maintenance, but if doing so doesn’t resolve your dust issue, the blower fan and ductwork that are also part of your furnace’s filtration system may be failing.
Yellow Pilot Light
If your furnace operates on natural gas, you have probably noticed the blue color of the pilot light. A change in the color of the flame from blue to yellow can indicate a malfunction or even a dangerous carbon monoxide leak. If you notice a yellow pilot light, immediately turn your furnace off and call a technician.
