Do you have a furnace that makes loud noises? Some property owners are not worried when their furnaces make loud noises, and unfortunately, some individuals get accustomed to the sounds. This can lead to their furnaces breaking down, which can be an inconvenience in an extremely cold winter. One way to reduce the chances of this happening to you is to ensure that you keep furnace maintained. The following are sounds that furnaces can make and what causes them.
Rattling can be caused by loose parts. It can also happen if a furnace is situated on an unleveled floor. Another potential problem is an issue with your ducts. The HVAC contractor can inspect the furnace and replace the damaged ducts if needed.
Clogged filters and dirty burners can cause booming sounds. These two issues can cause serious issues such as carbon monoxide leaks and the need for repairs. For example, dirty burners can damage heat exchangers, which can result in more extensive repairs.
Screeching sounds occur when there are issues such as the blower wheel hitting against other parts of the furnace. Another potential issue is that the motor in your furnace is malfunctioning. Either of these parts may also be broken, which is why it is a good idea to get a professional to inspect it.
Clicking or Ticking Sounds
Clicking or ticking sounds can occur due to a faulty flame sensor. An ignition system that is damaged can also cause this issue to occur. Issues between the gas valve and pilot light can also cause this phenomenon to occur. There are a few other issues, such as a broken flame sensor, that would need to be replaced. Due to multiple things being able to contribute to this issue, it is important to get a professional diagnosis from an HVAC contractor. Always keep in mind that the parts in your furnace all work together for proper operation. You may hear intermittent clicking or ticking sounds, but if it occurs every time you turn on the appliance, there is likely a serious issue that should be handled by a professional.
An HVAC company is a good resource to use when you're learning about furnace maintenance. They can also teach you how to change your furnace filter, as dirty filters can cause fires and result in poor energy efficiency. Repairs are likely to be more expensive than general maintenance, so contact a contractor immediately when you think something has gone awry with your furnace.
