The last thing you want to hear from your furnace is loud noise. Excessive noise in heating systems, like banging, buzzing, or whistling, can be an indicator of damage, whether it be with your furnace or something adjacent, like the pilot light or thermocouples.
If you’re wondering “Why is my furnace so loud?” let CREW Heating & Cooling, the leading provider off expert furnace repair in Spring, TX, show you loud furnace causes and how to correct them.
Identifying Loud Furnace Issues in Spring, Texas
What does a furnace in need of urgent repair sound like? When it comes to furnaces, noise is something you can expect. Since the furnace heats your entire home, it should at least make a low humming noise.
However, if you can hear your furnace in the next room, or can’t hold a decent conversation while standing next to it, that is cause for some concern. If you notice an unusual noise coming from your furnace, check it immediately. Unkept furnaces are more likely to cause house fires, especially if the appliances are old. You may want to have a professional check your furnace if you hear any of these sounds coming from it.
Buzzing
Quieting a noisy heater may involve fixing your blower motor. Buzzing typically means that your furnace is working harder than it needs to, attempting to blow heat into the house with faulty hardware.
This may mean your blower is broken or just dirty. If your fans are dirty, this can also result in a buzzing noise that persists each time you turn the furnace on. Luckily, if the buzzing is due to a dirty air filter or blades, a quick change can help resolve that issue without calling an HVAC repair technician.
Humming
When asking, “Why is my furnace so loud?” it’s important to remember that soft hums are normal for a running furnace. However, a loud hum that’s persistent enough to be noticeable outside the furnace room is a potential danger. If your furnace is humming loudly, the problem may lie with the motor or blower fans.
While a humming furnace is probably the least severe of noises that a furnace can make, leaving it alone to continue isn’t good for your hardware. Humming may later turn into buzzing, which spells imminent damage to your furnace.
Clicking
Clicking is another furnace issue that should not go unchecked and may be hard to detect at first. Clicking noises may be occasional or intermittent as the furnace runs.
Usually, a clicking noise from your furnace means there’s a fuel problem or something wrong with the ignition system. If you have a particularly old furnace, such as one with a pilot light, it may be time to consider an upgrade or, at the very least, a pilot light replacement.
Whistling
If your furnace is whistling, this could indicate either a leak or some other kind of dissipating moisture from within the machine. If your furnace is in a basement or other damp area, condensation or other accumulated moisture may be the problem, especially during hot months.
High-pitched whining sounds mean the furnace may be leaking gas from the valve, which releases carbon monoxide into the air. By using a detector, you can rule out this possibility easily.
Knocking
Knocking is one of the trickiest problems for the layman homeowner to diagnose. If your furnace makes popping noises, the problem could be anything from unstable gas flow to a dirty coil.
Dirty interior mechanisms can cause delays in the furnace’s functions, making loud bangs and pops upon ignition. Anything involving malfunctioning gas flow can be dangerous for your home and furnace. If you notice this problem, we recommend that you do not try to fix it yourself; get a professional to help.
