Gas furnaces are one of the best ways to provide heating to a home during a cold winter. They’re powerful and reliable, and they often cost less to run than an electric furnace.
Consumers are sometimes concerned about the safety of using a natural gas furnace, but these units are designed with numerous safety features. However, if you use a gas furnace, we recommend you pay attention to any strange sounds coming from it. These can warn of potential furnace malfunctions, and the best way to keep your furnace running safely and effectively is to stay ahead of any problems. If you run into any of the following sounds with your furnace this winter, you may need to call our technicians for heating repair in Champaign, IL.
Common Warning Sounds From a Gas Furnace
Rattling or Banging Sounds
If you hear a rattling or banging sound from your gas furnace, it might indicate a loose part or a delayed ignition issue. A loose part, such as a panel or screw, can rattle when the furnace is running, but this is often a minor fix. However, a banging sound might point to delayed ignition, which occurs when gas builds up in the combustion chamber and ignites all at once. This can be dangerous and may damage the furnace if not repaired, so it’s crucial to call a professional.
Squealing or Screeching Noises
Squealing or screeching sounds often indicate a problem with the blower motor, such as worn-out bearings. These components help keep the furnace’s fan running, which circulates warm air throughout your home. If the blower motor isn’t functioning correctly, your furnace may struggle to heat your home evenly, or the furnace’s heat exchanger could overheat. A professional can lubricate or replace the necessary parts to eliminate the noise and ensure everything is working right.
Booming Sounds
A booming noise is usually a sign of a dirty burner. When the burner is clogged, gas can accumulate and ignite in bursts, creating that “boom” sound when the furnace starts up. This not only affects performance but can also create a safety risk. Regular maintenance, which includes cleaning the burners, can prevent this problem. However, if you hear a booming sound, call a technician to inspect and clean the burner to make certain.
Clicking Noises
A continuous clicking sound coming from your furnace could indicate a problem with the ignition system, such as a failing flame sensor or issues with the ignition switch. While occasional clicks during startup are normal, ongoing clicking signals that the furnace isn’t igniting properly. Ignition issues can often lead to your furnace shutting down or failing to heat your home adequately, so it’s best to have this checked by a professional.
Humming Sounds
A low humming sound is usually normal in a gas furnace. However, if the humming becomes louder or more constant, it could indicate an issue with the fan motor, transformer, or capacitor. Since a failing fan motor or transformer can prevent your furnace from effectively distributing warm air, it’s essential to have a professional inspect the system to see if anything needs to be repaired or replaced.
