Common Signs Your Furnace Might Not Make it Through the Winter

For Little Rock homeowners, the onset of fall means taking the time to slow down and prepare for the winter months that are ahead. This can be in the form of boosting air sealing and insulation, but it’s often necessary to also take a close look at the current health of your furnace. It’s not at all uncommon for people to think their furnaces are prepared to deal with the winter months, only to experience a breakdown on the coldest day of the year. Clearly, there’s got to be a better solution, and the team at SEAL is ready to help.

Is your furnace going to make it through the winter, or is it time to bring in a professional to ensure that everything is operating properly? Here are a handful of “warning signs” to look for, all of which may point to a furnace that’s on its way out.

Low Rumble

If you have an oil-burning furnace and tend to hear a low “rumbling” sound during operation, it’s time to take a closer look. Rumbling may be the result of oil that has gotten into the combustion chamber, resulting in fumes that can be sent throughout the home. Many people mistake a low rumble for being a normal part of furnace operation, but it may be a real problem that requires furnace repair or maintenance.

Rattling/Rocking Noises

This is a common issue that plagues furnaces throughout Arkansas, and it can be difficult to pinpoint exactly what the problem is at face value. Rattling and rocking noises that occur on a regular basis may be the result of something as simple as a loose cover panel on the furnace, but there could be more at play. These types of noises could indicate that your heat exchanger is cracked, which means that toxic air may be infiltrating the home. Either way, it’s essential to work with a professional to ensure that nothing major is happening.

Scraping/Squealing Sounds

No one wants to have to endure scraping and squealing sounds in their home, but they’re quite common in furnaces that are near the end of their lifespan. Scraping sounds typically result from ball bearings that have worn out, while squealing usually means a frayed or split belt. In either scenario, it’s best to turn your furnace off and call a professional.

Flickering/Yellow Pilot Light

Take a look at the pilot light on your heating system. In most cases, it should be lit blue. If it’s either yellow or is flickering, excess carbon dioxide may be to blame. Adjusting the burner light screw may help, but if it doesn’t, you’re likely in need of a replacement.

Failing to take action when your furnace is suffering can lead not only to a less comfortable home, but also to a dangerous home, if carbon monoxide is leaking from your unit. Ready to protect your family? Contact us today to learn more or to schedule an appointment!
