Winter is in full swing, and your furnace becomes the cornerstone of your home’s comfort as temperatures drop. However, increased usage can cause wear and tear, leading to potential issues and breakdowns. That’s why keeping your furnace running efficiently and reliably is essential.

In this blog post, HVAC experts from Daigle Plumbing, Heating & Cooling will discuss the top signs that your furnace may be experiencing problems and provide tips for furnace maintenance to keep your system in top shape. Whether you’re a homeowner or a renter, these signs can prevent costly repairs and ensure the safety of your home.

Unusual or Strange Noises Coming From The Furnace

One of the noticeable signs that your furnace may have a problem is unusual or strange noises. These noises can range from rattling and banging to screeching and squealing, often indicating an issue with your furnace. While some noises may be harmless and can be remedied with a simple fix, others may require more extensive repairs.

A common cause of furnace noises is a loose or damaged component. A loose blower motor or a broken belt can cause a rattling or banging noise. These components may need to be replaced to ensure your furnace functions correctly.

Ignoring unusual furnace noises can lead to more significant issues, such as a system breakdown or fire hazard. If you hear any strange noises from your furnace, it’s best to contact a professional HVAC expert to diagnose and repair the problem.

Weak or No Airflow from The Furnace

Weak or no airflow from your furnace is another sign of an issue with your heating system. When your furnace works correctly, you should feel warm air flowing through the vents. However, if you notice that the air from your vents is weak or non-existent, it could be a sign of a problem.

There are several potential causes of weak or no airflow from your furnace. One common cause is a clogged air filter. A clogged air filter restricts the airflow. It makes it more difficult for your furnace to circulate warm air throughout your home.

A blocked or damaged air duct can also cause weak airflow from your furnace. Over time, air ducts can become clogged with debris or damaged, causing a reduction in airflow.

A Yellow or Flickering Pilot Light

It is a tiny flame that ignites the gas in your furnace and should always be a steady blue flame. If you observe that your pilot light is yellow or flickering, it could indicate a few different issues.

A dirty or clogged burner is one potential cause of a yellow or flickering pilot light. When the burner becomes dirty, it can cause the flame to burn inefficiently and produce a yellow or flickering light. A dirty burner can also cause a carbon monoxide buildup.

A malfunctioning thermocouple is another potential cause of a yellow or flickering pilot light. The thermocouple is a small device that shuts off the gas supply if it doesn’t detect a flame. If the thermocouple malfunctions, it may not detect the flame correctly, causing the pilot light to flicker or go out.

Higher Energy Bills

Has your energy bill increased suddenly? Your furnace might be the culprit. A malfunctioning furnace can cause your energy bills to skyrocket. Here are some potential reasons why:

Firstly, if your furnace is not maintained correctly, it can become inefficient and consume more energy to produce the same heat. This inefficiency can cause your energy bills to increase. By having your furnace regularly maintained, you can ensure that it’s running efficiently, which can help to reduce your energy bills.

Another reason your energy bills might be higher is that your furnace might be too small for your home. If your furnace is not powerful enough to heat your home, it will have to work harder to produce enough heat, which can lead to increased energy consumption and higher bills. In this case, upgrading to a bigger furnace could reduce energy bills.

Frequent Cycling On and Off

Furnaces are designed to cycle on and off automatically to maintain the desired temperature in your home. However, if your furnace cycles more frequently than usual, it could indicate a few different issues.

One potential cause of frequent cycling is a dirty or clogged air filter. A clogged air filter can restrict the airflow in your furnace, causing it to overheat and shut off. When this happens, the furnace will turn back on once it has cooled down, leading to frequent cycling. Regularly changing your air filter can help to prevent this issue.

Frequent cycling can also be a sign of a large furnace. If your furnace is oversized, it will cycle on and off frequently, resulting in increased wear and tear and reduced efficiency on the system. So, you may need to replace your furnace with an appropriately sized model.
