Common Furnace Sounds Explained
One of the most persistent myths in home heating is that any unusual sound coming from your furnace signals an expensive repair bill in your future. At Lambert Heating & Air Conditioning, we’re here to put your mind at ease by explaining why this isn’t always the case.
Understanding Normal vs. Abnormal Sounds
Many homeowners throughout Sioux Falls and surrounding communities panic when they hear their furnace making noise. The truth is, some sounds are completely normal during operation:
- Expansion and contraction sounds (mild popping)
- Gentle humming from the blower motor
- Brief clicking when the system starts or stops
- Soft whooshing from air movement
When to Actually Worry
However, certain sounds do warrant professional attention:
– Loud banging or metal-on-metal scraping
– Continuous squealing
– Rumbling after the blower turns off
– Excessive vibration
Preventive Maintenance is Key
Regular maintenance can prevent most serious issues before they develop into costly repairs. Many concerning sounds can be eliminated with simple solutions like:
– Tightening loose panels
– Lubricating moving parts
– Cleaning burners
– Replacing worn belts
Remember, being proactive about furnace maintenance isn’t just about preventing noise – it’s about ensuring your system runs efficiently throughout our harsh South Dakota winters. Don’t let myths about furnace sounds keep you up at night. When in doubt, have a professional technician evaluate the situation for peace of mind.
