We all prefer the warm comforts of our homes during the winter, though the Vegas desert has mild winters compared to some. However, we often get caught up in these comforts and ignore the haunting sounds of protest our furnace makes. Since fixing it can be a nuisance, it is easy to deny that something may be amiss with our heaters when they start making an odd sound. It is important that you never neglect these signs of furnace disrepair. For instance, if you hear a rattle it can be something as benign as an easy-to-fix loose panel, or on the other hand it can lead to a hazardous carbon monoxide leak because it is a cracked heat exchanger. You need to call in a professional in the event hear anything outside of the normal cycling of your furnace and air whooshing through your vents. Today, we at Hal Mechanical would like to elaborate further on these furnace noises that are cries for attention.
Furnace Makes Banging Sound or Boom Noise
A dirty burner is the general cause for the banging and booming you hear from the furnace. Though it may sound nonthreatening, it can be dangerous. Due to dirt and build-up, the noise you’re hearing is caused by a delay in ignition. As a result, the system builds with gas and a small explosion occurs inside the furnace when it ignites. A cracked heat exchanger leads to carbon monoxide leaks if not addressed. Because there is too much room for error that can lead to costly consequences, it is highly recommended that you do not clean the burner yourself. It is in your better interest to call in a pro, especially when you are dealing with natural gas.
Furnace Making Clunking Noise
You probably are hearing metal-on-metal when you hear the clanking sound that resembles metal-on-metal. A serious problem with the furnace’s blower wheel is typically the cause of this noise. To prevent further damage to the wheel, you need to turn off your furnace and contact a pro right away if this is the case. The longer the damage carries on the pricier it becomes to repair.
Rattling in Furnace Vents
Rattling could be something as simple as a loose panel that needs to be tightened as we mentioned, but don’t assume. For instance, a broken heat exchanger can be the cause of the rattle. Other concerns can include issue with your blower or a lack of airflow from a dirty and clogged up air filter. Both for heater performance and for your safety, requires professional attention right away, no matter this issue.
Furnace Screeching & Squealing Noise
The blower motor in your furnace isn’t working as it should, can be indicated through loud screeching noises. The heat produced by your furnace won’t even be able to circulate warm air around your living space successfully due to a malfunctioning or broken blower motor. The fix is that you need to lubricate the blower motor. The fan not working can also be the issue. It is essential that a professional HVAC technician visits your home in order to get a proper diagnosis. Once the issue is properly diagnosed, the problem can be properly rectified.
