Furnaces are robust machines that can make a lot of noise. Although some noises are a normal part of their run cycle, there are concerning sounds you need to be aware of that spell trouble for you and your heating system. Here are some sounds that should ignite your concern.
Furnace Sounds and What They Might Mean
• A loud bang or pop occurs when the furnace turns on – A popping, booming or banging noise when your oil or gas furnace turns on is not normal. It may indicate that the system’s burner is having trouble reaching a temperature hot enough to ignite the fuel. This causes fuel to build up for longer than it should. When it finally ignites, the excess fuel or oil pops, creating the loud noise. It’s crucial to have your furnace examined to avoid a potential fire hazard and prevent your system from experiencing a critical failure.
• Your furnace rattles and rumbles – A rattling or rumbling noise may indicate there is loose debris, faulty ductwork or a broken fan blade in your heating system. You might believe you can pinpoint the source of the problem and fix it yourself, but it’s best to have a professional furnace technician do it for you. Furnaces have complex parts, and you may end up unexpectedly damaging your system or hurting yourself if you attempt a DIY approach.
• You hear a repetitive clicking noise – A repetitive clicking noise may mean there’s an issue with the ignition or heat exchanger. Although it might only require a simple furnace tune-up, it’s best to avoid trying to fix either one of these components by yourself. Call a professional to perform a tune-up for you and diagnose your system.
• A loud squealing noise is emitting from your furnace – A high pitched squealing or screeching noise radiating from the bellows of your furnace might mean your belt-driven motor is loose or damaged. Your belts and shaft bearings may need to be lubricated. Again, it’s best to have a professional HVAC technician lubricate your belts for you.
