Hollis, NH Homeowner Has Concerns
While it may be normal for your heating system to make some sounds when it turns on, excess noise or a sudden new sound may be indicative of a problem. A banging or whistling noise coming from the furnace is out of the norm and should be addressed by an HVAC professional. Rumbling, or sounds when the furnace is off, are also clear indicators that service is needed. Some of the most common reasons for heating system noises include clogged air filters, a loose blower fan, worn-out fan belt, or a problem with the fuel ignition.
A homeowner in Hollis had noticed that there was an unusual noise coming from his home’s furnace when it was running. Concerned, he contacted the team at Joyce Cooling & Heating Inc..
Recognizing What Are Normal Sounds for Your Furnace
A slight whooshing sounds when the furnace first turns on or a gentle roaring is normal as the air begins to pass through the home. If the rumbling is loud or continues even after the furnace has turned off, there may be a problem with the burner. This problem can be caused by extra fuel in the combustion chamber after the furnace has completed the heating cycle. This can lead to high levels of carbon monoxide in the home and should be addressed immediately.
A humming noise coming from the furnace, or a whirring noise, is generally not a cause for alarm. Particularly in new furnaces, the transformer might make this noise as it adjusts. If this sound continues throughout the heating cycle, and not just at the beginning, there may be a problem with the motor. A louder than normal humming can also be a sign that there is a problem with the fan, and it will need to be replaced.
In general, if you are suddenly hearing unusual noises, or if you have noticed the sounds coming from your furnace have recently become much louder, it is a good idea to have an HVAC technician look at the unit. The homeowner in Hollis had a Joyce Cooling & Heating Inc. Technician check his heating unit. The technician was able to identify the cause of the problem, a worn-out fan belt. Replacing this part and performing maintenance on the unit corrected the issue and the heating system is now running seamlessly.
