When your furnace is operating properly, it should provide heat without making too much sound. While it’s normal to hear your furnace making noise as it begins running, other disruptions are signaling your furnace needs immediate professional assistance.

Here are some of the most common furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating professionals are here to help with the best furnace repair in Bartlesville, Oklahoma.

1. Furnace Makes a Banging Sound

You may have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s essential to schedule yearly furnace maintenance with Farris Heating & Air. One of the things our technicians do during this service is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can leak carbon monoxide, which is normally vented outdoors. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Farris Heating & Air recommends turning it off and contacting us at 918-333-0376. Significant natural gas in your furnace or a cracked heat exchanger are dangerous problems that should get immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide heated air throughout your house. If the ductwork wasn’t put in correctly or is getting dated, it can make a lot of noise when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Call Farris Heating & Air at 918-333-0376 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or cooled air across your house, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be the result of something little, like a loose screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 918-333-0376 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to alert you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again rapidly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is operating if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Farris Heating & Air can assist you. It’s critical to get loose ductwork fixed without delay, because it can result in comfort problems in your house and increase your heating bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise usually means there’s trouble with your furnace’s blower. Switch off your furnace off immediately and contact our professionals at 918-333-0376 for support.
