You should expect the furnace in your home to make some noise when it’s working, but nothing too loud or distracting. Read on to learn what’s wrong if your furnace in Perry, KY, is noisy.
Banging
Do you have a gas furnace? Hearing a loud bang or boom can mean there’s a delay in the ignition process.
This can occur if gas has time to build up before a successful ignition. It’s like a small explosion occurring in the furnace.
The cause of this sound is likely a dirty burner or faulty ignition system. Ask an HVAC service technician to perform an inspection for this issue, as dealing with burners and the ignition system can pose a fire hazard.
Whistling
If anything restricts furnace airflow, you might hear a high-pitch whistle. Things that can restrict airflow include a dirty filter, debris in the ductwork and blocked vents.
You should replacethe filter to see if that solves the problem. If the whistling continues, the next step is to check the ductwork and vents.
Rattling
A loose panel or other loose part inside the furnace can cause a rattling sound. This can happen when screws and bolts come loose from vibrations within the furnace. If the rattling sounds like it’s coming from the heat exchanger, that could mean it has a crack.
Buzzing
Buzzing can indicate an electrical problem with the furnace. For example, an electrical problem with the control board could cause a buzzing sound. The control board receives signals from the thermostat and controls the blower motor, ignitor and gas valve.
It can be worrisome when your furnace starts making loud noises, but it’s usually something that a repair can fix. Contact Appalachian Refrigeration, Heating & Cooling to schedule your furnace repair around Perry, KY.
