When your furnace makes abnormal sounds, the kind of sound can give clues as to what the problem is. Depending on the sound, the solution may be easy to deal with at home or it may be something that requires a professional to remedy. Here are four furnace sounds you should pay serious attention to in Poquoson, VA.

1. Scraping

Most people can’t stand the scraping sound a furnace can make because it’s as irritating as fingernails on a chalkboard. Scraping means sharp metals are making contact with other parts of the system. If this happens, turn off your furnace to prevent extensive damage, and call a professional for help.

2. Banging

A banging sound that occurs when the furnace turns on likely means there is an ignition problem. Another common reason for banging noises is dirty burners. Broken or disconnected parts can also cause banging noises.

If your furnace is banging, you should turn it off immediately. This will prevent additional damage to the system while you’re waiting for an HVAC technician to arrive.

You can prevent many of these maintenance-related problems in Poquoson, VA, by scheduling furnace maintenance on a yearly basis. During maintenance, we clean the burners, inspect the ignition, and clean and inspect other key areas of the furnace.

3. Squealing

Squealing usually indicates that parts of the system, like the bearings, need lubrication. During furnace maintenance, we lubricate the moving parts of the system, which is another reason maintenance is necessary on an annual basis. You don’t want these moving parts to dry up and trigger other problems with the furnace.

A loose belt is another possible cause behind furnace squealing sounds. Like lubricating the bearings, this is a simple fix for heating repair technicians. Don’t delay having the furnace repaired because you don’t want parts breaking as it attempts to operate.

Whenever your furnace begins making noises that you never heard before, you should hire an HVAC technician to diagnose and repair it. When you call, a professional may be able to use the kind of sound the furnace is making to recommend whether to continue running your furnace or stop and wait for a repair person.
