Like most appliances, furnaces are noisy while they work. However, a well-maintained one shouldn’t produce a lot of noise. Loud, strange noises coming from your furnace certainly indicate a problem.
Your equipment may be making loud noises due to several issues. A broken one will produce various sounds, including popping, whistling, slamming, and scraping. This blog post will discuss several causes of unusual furnace noises.
Gas buildup
Do you hear a loud and banging sound when you turn on your furnace? This may indicate gas buildup. Never ignore this kind of noise. It might cause the heat exchanger to crack. This would be costly and unsafe. Immediately turn off the system and contact a Calgary furnace repair specialist.
It’s possible that dirty burners delayed the ignition. This allows the gas to accumulate and “explode” when the ignition does occur. Your specialist will examine and clean the burners as part of the tune-up.
Loose or damaged blower wheel
A problem with the blower wheel will create a very unsettling scraping sound that sounds like metal rubbing against metal. It might have become loose, which would explain the scratching sound. Or perhaps it has been damaged and requires a replacement.
Turn off your system right away if you hear this noise. Then, check to see whether the wheel is damaged or loose. When in doubt, get a technician to check it immediately to ensure there aren’t any major problems with your blower wheel. Over time, these problems may cause your system to noticeably deteriorate.
A malfunctioning burner
Your furnace might be noisy and dangerous if the burner isn’t working properly. Problems and a delay in ignition could occur with the heat exchanger. This result of a burner malfunction may indicate a potentially hazardous issue. Have a professional check your burners to ensure no further harm to your furnace.
Damaged blower motor
Is your furnace producing squealing and screeching noises? That suggests that there might be a problem with your blower motor. Specialists can normally fix it by lubricating the blower motor. You can fix it at home by lubricating your blower motor. Choose an appropriate furnace lubricant to ensure the best results.
Loose parts
Your furnace will typically generate rattling sounds when parts are loose. Make sure your furnace’s doors and panels are securely fastened by tightening any loose screws. It’s also possible that the furnace’s internal mechanical components have loosened over time. Before you investigate, turn off your furnace and get aid from a professional to determine which parts have come loose.
Ductwork problems
It might be very concerning if your furnace begins to make loud popping and banging sounds. Ductwork problems typically cause these. As air flows through your ductwork, it can warp and rattle due to damage or loosening. The metal may start to pop as it expands.
Call a furnace specialist to prevent more ductwork damage. In the worst situation, the entire duct system must be replaced. This can be costly and time-consuming.
The takeaway
Planning furnace maintenance with a skilled technician will help you prevent most of these scary furnace noises.
