5 Unusual Signs Of Impending Furnace Problems

Sometimes it's easy to tell when your furnace needs maintenance. The usual warning signs are so obvious that it's hard for most homeowners to miss. However, not all warnings are as noticeable as the typical bad odors or loud noises. There are plenty of warning signs that are so subtle that they're easy for the average homeowner to miss. The following article highlights a few of these subtle and unusual signs of furnace trouble on the horizon.

1. Yellow Flames

On a gas- or oil-fired furnace, a bright blue flame is the symbol of good furnace health and efficiency. If the flame is a yellowish color or the flame itself flickers constantly, it's an indication that the furnace isn't burning its fuel as efficiently as it should. Dirty burners and fuel supply problems are a common cause of a yellowish or flickering flame, although high carbon monoxide levels caused by faulty venting can also cause this issue.

2. Excess Moisture

If you see heavy amounts of condensation on your windows or exterior walls, then it's also a likely sign that something is amiss with your furnace. Insufficient airflow caused by a faulty blower motor, a clogged air filter or faulty vents can lead to condensation problems elsewhere in your home.

3. Animal Activity

You'd be amazed at how much damage rodents can do to your home, especially when it comes to mechanical systems like your home's heating equipment. Mice, rats, squirrels and other rodents can chew through wires, urinate on sensitive circuitry and leave droppings behind, causing your furnace to malfunction without any outward signs of trouble. If you're actively dealing with a rodent problem, there is a good chance it could affect your furnace.

4. Constant Thermostat Adjustment

You shouldn't have to constantly fiddle with the thermostat just the find your ideal level of comfort. If you do, then there is a good chance something is wrong with the thermostat or the furnace itself. Defects and old age can cause thermostats to go out of spec, resulting in inaccurate temperatures. There is also the possibility of your furnace not being able to keep up with your home's heating demands.

5. Steadily Rising Utility Bills

If the cost of powering your home steadily creeps upward, your furnace may have something to do with it. Heating and cooling accounts for nearly half of a typical home's utility expenses. A faulty furnace can cause your utility costs to skyrocket if not addressed quickly. 

If you notice any of these issues in your home, consider contacting a local furnace repair company.
