Additionally, we’ll let you in on where you can find the best professional furnace repair in Kalispell, MT.
Rattling and Rumbling
When your furnace is making an unusual rattling and/or rumbling noise, it is probably due to a loose component. This most commonly occurs in the blower motor, hot surface ignitor, heat exchanger, or gas burners. This situation increases the risk of carbon monoxide poisoning. If the rattling and rumbling persists after a couple of tries, it’s time to contact a professional HVAC technician immediately.
Screeching and Squealing
High-pitched squealing noises are an indicator of a problem with the furnace’s blowing motor. This could mean a damaged or loose belt, but the issue could be more complex. In any case, contacting a certified HVAC professional is highly recommended.
Thumping and bumping noises like from a broken washing machine spinner, may be caused by a small gas explosion that happens due to a delay in ignition. Gas often gets built up in a combustion chamber when the burners in your furnace do not ignite on time. Do not attempt to fix a gas burner without a licensed professional. Taking apart the heat exchanger or burners can lead to a gas leak in your home.
If your furnace is making a scraping or scratching noise, this can be due to a problem with the bearings within the surface blower. This could also mean that the blower wheel may have come loose. In case the problem is with the bearings, you should note that regular lubrication is necessary for them to maintain proper function. In either case, contacting a professional HVAC technician for immediate repair is advised.
Popping and Banging
If you notice a loud popping noise when your furnace is activated, the cause of this problem is inflation in your air ducts. This could be due to the warm air that collides with the cold air ducts, which causes the metal to enlarge, producing a popping noise. Another cause of the noise may be contaminated gas burners in your furnace. Sediment will start to collect on the burners over long periods of time. If not cleaned out with annual maintenance, this causes gas accumulation and the potential to cause breaks and holes in your heat exchanger. A certified professional should be contacted immediately.
