Other than some clicking that may persist for a short time after you turn it on and a light hum that carries on through its operations, your furnace really shouldn’t make any noise. Since other sounds can indicate trouble, you should learn about what they entail for your ability to stay warm in Huntersville, NC, this winter. To help you, we’d like to explain three common furnace noises and what they mean.
Rattling
Rattling noises often suggest the presence of some debris inside your furnace. Various foreign objects, like pebbles, twigs and clumps of dirt, may find their way into your furnace and obstruct its functioning. They may tumble around the system’s interior and produce rattling sounds.
Another possibility is that your furnace’s panel door has come loose or some other bolts or screws have moved out of position. More rarely, rattling may hint that your furnace’s heat exchanger has cracks.
HVAC service technicians can tighten loose bolts and remove debris as part of a maintenance check. A cracked heat exchanger will require more extensive work, but it’ll also usually set off your carbon monoxide detector.
Grinding
These noises often mean that some part of your furnace is rubbing against another and sustaining damage in the process. The blower wheel is an especially common candidate for this. If you hear this noise, we recommend immediately shutting down your furnace and calling for repairs to prevent additional damage.
Whistling
If your furnace’s air filter becomes too dirty, it’ll choke off the flow of air through the system and adversely affect its overall performance. It can also produce whistling noises, which happen when air flows past the dirt on the filter.
Now that you know what to listen for, you can act quickly to rescue your furnace from trouble. If you hear anything strange, call Bradham Comfort Services and sign up for the best furnace repair services around Huntersville, NC.
