While winter does not officially begin until December 21, in many ways, it feels like it's already here. If your heater has been working overtime to keep the house comfortable, you may worry about it breaking down right when you need it the most. The guide below lists signs of impending furnace malfunction to be on the lookout for, so that you can arrange for heating repair before your family is left out in the cold.

Common Signs of Furnace Malfunction

1. Unusual Noises

A furnace should run smoothly with a minimum of noise. Grinding, clattering, or squeaking, especially if they are new, require attention. These sounds could indicate that parts have loosened or are rubbing together and the longer you let it go, the more costly it is likely to be.

2. Dust

If you notice increased dust on the furniture or if the members of your household start sneezing without being sick, the furnace's filter is probably clogged. However, if you try changing it yourself and it doesn't resolve the problem, call a heating repair specialist.

3. Uneven Air Temperature

If there are cold areas in your home where the heat doesn't reach, there is likely an issue with the blower fan. Call your HVAC service to check the effectiveness of the system and make any necessary repairs.

4. Higher Heating Bills

Increased heating costs may mean the furnace isn’t running effectively and, therefore, must operate more often to keep the desired temperature. However, the causes for this could be many and require diagnosis by a heating repair specialist. Carbon monoxide can be a by-product of an inefficient or malfunctioning furnace, so having your system serviced and winterized each year is a good idea.

5. Yellow Flame

If you have a gas furnace, check the pilot light. It should be blue. If the flame is yellow, this is a sign that the unit is malfunctioning and could be emitting carbon monoxide. Turn the system off and call a heating repair technician right away.
