Signs Of Impending Furnace Trouble

Issues with your furnace can leave you in the cold if they catch you unexpectedly. The following are some signs of impending furnace troubles. Learning to recognize these can help keep you warm this winter.

Thermostat inconsistencies

It can be frustrating when you turn up the thermostat but your home doesn't warm up sufficiently. If you start to notice that the temperature in your home doesn't match the setting, then you have a problem. In most cases, the issue is with the thermostat itself, which will only require a simple repair or replacement. Thermostat problems often surface as the need to set the temperature at a specific interval above or below the desired temperature. Other common causes are issues with the wiring or a problem with the furnace itself. These issues tend to surface as random temperature fluctuations that are hard to predict, thus making it even more difficult to find a comfortable setting for your home.

Noisy blower or fans

It's not uncommon to be able to hear the furnace pop on or the low hum of the blower and fans. It becomes a concern when the noises change or become much louder. Loud pops, clanging, squeals, and whines all indicate that something is amiss. Best case scenario is that the system needs lubrication or something is loose. In some instances, the bearings may need to be repacked in one of the moving parts inside the furnace. In more severe instances, you may need to have the blower motor rebuilt or replaced, or it may simply be time to purchase a replacement furnace. Although blower issues aren't usually dangerous, you should still turn off the furnace until you can have it serviced.

Pilot light problems

Gas and oil furnaces require a properly functioning pilot light since this is what fires the burner to produce the heat you crave. If the light is constantly going out, there could be an issue with the gas valve. Another common issue is a light that flickers or doesn't burn evenly. A properly working pilot light has a consistent blue flame. Most often, the valve has simply become obstructed, and a technician can clean it out. Occasionally there can be an issue with the valve itself, requiring replacement of the valve. Very rarely does a pilot light issue indicate that the entire furnace needs replaced, but you will need to consult with a technician to be sure. Since pilot light issues can put you at risk of fire, explosion, or carbon monoxide poisoning, it's vital that you shut down the furnace until you can have it serviced.
