A furnace, like other appliances, produce some unnoticeable noises during operation. When sudden loud noises pop up while your heating system is operating, you should take immediate action because they indicate an problem that could jeopardize your household in Butterfield, TX. Here are some strange furnace noises that you shouldn’t ignore.

Banging Sounds

Banging furnace sounds when the appliance is kicking on could indicate an ignition problem. The gas valve opens when the thermostat signals the heating system to start a cycle, so the pilot light or ignition system ignites gas immediately. An ignition system issue causes gas buildup that creates the banging sounds in the chamber, which could be due to clogged or dirty burners, low gas pressure or a weak flame.

Squealing Noises

A squealing sound coming from your furnace could signal an issue with the blower motor. A loose belt could also be the reason why you hear squealing noises from the heating system. You need to hire a heating repair professional to inspect the appliance because the problem may be more complex within the blower motor.

Rumbling Noises

You need to take action if the heating system completes a cycle and makes a loud rumbling noise. Issues with flame sensors, pilot lights or burners often cause rumbling furnace noises, and these culprits increase the possibility of carbon monoxide poisoning, which is why you need the help of an HVAC technician. When fuel continues to burn in the heating system combustion chamber when the burners shut down, it could cause rumbling sounds from your furnace.

Scraping and Grinding Sounds

Scraping and grinding sounds indicate dry bearings within the blower motor of your heating system. Furnace bearings require regular lubrication to ensure that they function correctly without making unusual noises. That’s why you need a professional to maintain your furnace and lubricate the blower motor regularly.
