Do Not Ignore These Noises From Your Furnace

Ignoring the sounds coming from your furnace can be a costly mistake. Even if the noises are low-pitched, bearable and not at all disruptive, it doesn't mean you should leave that sound alone. It could be a warning sign of a malfunction or issue that has yet to become serious.

From hissing and ticking to clanking and thumping, furnaces can make a number of strange noises. It is important not to ignore furnace noises as they can indicate problems that may lead to costly repairs or create unsafe conditions in your home. Some furnace noises are perfectly normal, such as during start up or shut down, but unexpected sounds can often be indicative of deteriorating parts in the furnace. It’s best to have furnace issues checked by one of our technicians to review the source of the noise and assess any concerns quickly and safely.

Different Furnace Noises and Their Cause

As mentioned previously, furnaces make different sounds depending on the cause of the noise. Strange sounds can be a worrying sign that something is wrong with your furnace and you should have it checked out right away. A furnace humming sound is usually caused by a healthy furnace but may also be due to loose parts, improper wiring, and blocked filters. On the other hand, if you hear loud banging or clanging noises coming from your furnace, this could indicate a problem with the blower motor or fan blade. Scraping noises could be caused by corrosion or debris buildup while squeaking and squealing noises are most likely caused by worn-out bearings in the furnace motor. If you notice any of these furnace noises, it’s essential to contact one of our qualified HVAC technicians for an assessment. Neglecting these warning signs can lead to dangerous situations like furnace breakdowns and even carbon monoxide poisoning.

Booming Sound Coming From The Furnace

A booming sound coming from your furnace can be concerning, and sometimes it can indicate a serious issue. While sometimes it is just the result of minor adjustments occurring under the hood of your furnace, other times it could signal something more serious like an overheating motor. This type of sound should never be ignored as failing to attend to a faulty heating system can cause significant damage to the unit or even create a hazardous environment if flue gases are not exhausted properly. Therefore, if booming sound has started emitting from your furnace, it’s best to call a professional HVAC technician right away to investigate and fix any problems before they become a greater issue.

Furnace Is Making Clicking Noises

There may come a time when you hear a clicking sound coming from your furnace. This clicking is usually caused by an issue with the ignitor, which is an electrical device that is responsible for starting up the gas in order to create heat. If not taken care of right away, the clicking sound could turn into an unwanted repair or replacement bill. That’s why it’s best to have one of our heating repair technicians inspect your furnace after you hear any clicking noises; diagnosing and fixing the problem early can often be cheaper than allowing it to worsen over time.

Chirping Noises Coming From The Furnace

Your furnace chirping? You will don’t want to overlook it. Chirping is often a symptom of a more serious problem with your furnace, such as worn out bearings, warped mounting plates, wheel misalignments, and other potential causes. A chirping sound might also mean that the belt on your blower is loose and needs to be tightened, which can be done effectively by one of our highly experienced technicians. If these underlying issues aren’t addressed in a timely manner, you may find yourself dealing with more costly repair work and discomfort due to malfunctioning equipment.

This is why we recommend getting to the root of the chirping as soon as possible by giving us a call. This is key for keeping your heating system in working order.

Furnace Is Making Rattling Noises

A rattling sound coming from your furnace is not something to ignore. If you are hearing rattling, screeching, or humming noises coming from the appliance, it’s likely caused by a loose part inside the unit. This can be especially dangerous if the rattling comes from near the burner area, as it could indicate a loose gas line which can pose a serious health hazard. It’s best not to attempt fixing these issues yourself and instead call us for an inspection if you hear rattling sounds coming from your furnace. The technician will identify the issue and replace any necessary parts in order to stop the rattling and keep your system running smoothly and safely.

Squealing Noises Coming From The Furnace

If there is squealing coming from your furnace, it may be cause for serious concern. This squeal can be a sign of a malfunctioning belt in the blower motor. If this is the case, the squeal will continue for as long as you run your heating system, creating an uncomfortable noise that no one wants to deal with. The squealing can also indicate something worse; a bearing failure in your motor, which can lead to larger problems down the line. If ignored, this problem could lead to costly repairs or even complete replacement of your furnace. Make sure to give us a call right away if you hear squealing coming from your furnace so you can make sure it’s running smoothly and efficiently before it becomes too serious.
