4 Imminent Signs Your Furnace Broke Down Recently

Your furnace is one of your home's most important assets. So, when it stops working, it creates a lot of chaos for your household. Especially if you live in a cold climate.

Most furnaces last for about 15 years. But, you might want to replace them even sooner because of high energy costs. If you're thinking about replacing your furnace, you probably want to know if there is something wrong before replacement. So, what are the imminent signs your furnace broke down?

Here are some of the signs you need a furnace replacement.

1. Common Noises If Your Furnace Breaks Down

Did you know that one of the main disadvantages of high efficiency furnaces is the high chance of a breakdown? Though these furnaces are more efficient than older models, the complex design and components often cause them to break down more quickly.

If your furnace breaks down, you may notice one or more distinct noises indicating a problem. If you hear an audible popping noise, this could indicate a malfunctioning fan or a problem with the blower motor. You may also hear a loud banging or humming sound. This can be an indication of a faulty igniter or burner.

If you hear a hissing or whistling sound, this can indicate a gas leak or a problem with the gas valve. Another sound you may hear is a rattling noise, which could mean a broken fan blade.

2. Understanding Odors That Signal a Furnace Malfunction

It is important to understand odors that signal a furnace malfunction to help prevent the possibility of a major malfunction that could lead to costly and dangerous repairs. Some of the odors that signal a malfunction could be a strong chemical smell, such as burning plastic or electrical wiring, a rotten egg smell, or a foul gaseous odor.

If you detect any of these smells coming from your furnace, turn it off and contact a professional to come and inspect it.

3. Discolored Pilot Lights

Discolored pilot lights in the furnace can be a sign of a potentially serious problem. They are typically either yellow, blue, or orange and indicate a carbon monoxide issue or another component breakdown. Yellow indicates a cracked heat exchanger or damaged burner, blue illustrates a problem with the gas valve, and orange is a sign that there may be an inefficient or insufficient fuel mix.

In any case, it is important to take care of discolored pilot lights as soon as possible to avoid hazardous conditions or further damage to the unit.

4. Low-Temperature Output

If your furnace is not producing enough heat, it is likely due to a broken furnace part. Things to check first would be the condensate drain and drain pan, the thermocouple, and the air filter. Faulty ignition systems, restricted airflow, and incorrect pilot settings are all common causes of the furnace not producing enough heat.

If the issue persists, it is best to call a professional furnace repair service to come and tend to your furnace.

Watch Out for These Signs That Your Furnace Broke Down

If your furnace broke down, it is not something to take lightly. It’s important to remove the immediate safety risks and contact a qualified service technician for a proper diagnosis.

If you notice any of the signs mentioned above, do not hesitate to call for professional help. Your home, your family, and your wallet all deserve the best furnace and service available.
