If your furnace is getting older, it may start having problems soon. Knowing what to look for will allow you to get the furnace repaired quicker, which may prevent you from having to purchase a new one. Keep reading for four problems you may have.
You need to inspect the filter on your furnace regularly. If you see that it is clogged replace it with a new one. Write down the number on the filter to ensure you purchase the right one. You can find these at home improvement stores or online. If you continue using your furnace with a clogged filter, this can damage the limit switch and the furnace will not function well. Over time the problem will become much worse and result in needing furnace repair.
Problems with Pilot Light
A major part of a furnace is the pilot light, which must function properly. If you notice the pilot light is a different color, such as yellow, or that it is flickering, this means carbon monoxide levels are high in your furnace. If you notice any change to the pilot light you need to contact a furnace repair company immediately to have this repaired. It would be best to power the furnace down until they arrive, so the carbon monoxide levels do not go up high inside the room.
Over cycling means the furnace turns off and on more frequently. This can be caused by many things, such as the filter may be clogged, there could be improper airflow, or the temperature setting may be too low or too high. This can cause the furnace to go out much quicker as it will be running all the time. Your power bill will go up because of the frequent cycling. If the problem continues, contact a furnace repair company as this may also be caused by an internal component.
Blowing No Air
If the furnace is not blowing any air this can be caused by many things. First, the blower may be clogged so check this and remove any debris that you find. Look at the blower for a flashing light. If you see that it is flashing red, this means there is a much bigger problem. It could be the blower is malfunctioning and needs to be replaced.
