Noise from your furnace can be both alarming and concerning. It’s important to know what the different sounds might mean so that you can resolve the issue as soon as possible. Here’s why your furnace in Camden, NC, is so loud and what to do about it.
Buzzing Noise
The buzzing of a furnace can be quite alarming and distressing, particularly when you have no idea what it means. The low droning hum of a furnace usually indicates that the blower motor has been activated and is running normally.
It could also indicate that the system is cycling on and off due to a safety switch or thermostat malfunction, which can be an easy fix. If the buzzing continues for more than a few minutes, it may be a sign of a more serious problem, such as a failing blower motor, faulty wiring or a clogged air filter.
Rattling Noise
A rattling noise from a furnace is usually caused by loose components, wear and tear or even improper installation. It could also indicate a failing blower motor, the fan blades hitting against the furnace’s cabinet, a failing start capacitor or debris caught up in the blower motor itself. If you’re hearing a rattling noise coming from your furnace, it’s important to have it checked out by a professional HVAC service technician as soon as possible.
Hissing Noise
Hissing could result from air escaping somewhere, such as a crack in the heat exchanger or a loose connection. It could also mean the gas pressure is too high, possibly due to improper settings or a faulty valve. If a rotten egg or sulfur smell accompanies the noise, it signals a possible gas leak.
If your furnace is making any strange noises, it’s best to get it checked out by a professional. Different noises can mean different things; some might be more serious than others.
