There are only two noises that are normal for a furnace to make: the temporary popping that arises from thermal expansion and the slight humming that accompanies normal operations. Any other sounds point to trouble. Here are three furnace noises that homeowners in Cypress, TX, should never ignore:
Whistling
Strange as it may seem, your furnace may start producing whistling noises if you allow its air filter to become too dirty. As dirt gathers on the filter, it’ll hinder further airflow. Since this dirt will almost certainly accumulate unevenly, it may create friction with passing air, which may manifest as whistling.
The solution to this problem is very simple: Keep your filter clean. We recommend replacing yours approximately once every three months.
Rattling
The two most common explanations for any rattling sounds coming from your furnace are loose parts and trapped debris. The former might include things like a detached panel door or some unsecured bolts while the latter might consist of things like dirt, twigs or pebbles. These things may seem insignificant, but they can undermine your furnace’s ability to function in the long run.
Periodic HVAC maintenance can take care of both issues. However, if your furnace’s heat exchanger cracks and leaks carbon monoxide into your home, this can also create rattling noises. This is a much more serious situation.
Grinding
Grinding noises almost always signal a major issue. Usually, they suggest that some of your furnace’s important parts, like its bearings, have worn down. A persistent buzzing sound that’s significantly louder than the furnace’s usual hum may indicate something may have gone wrong with its motor.
If you hear these noises coming from your furnace, we strongly recommend shutting it down and requesting professional help. A trained HVAC service technician can examine your system, diagnose the problem and take the necessary steps to solve it.
