When your furnace is running properly, it should provide heat without making too much disruption. While it’s common to hear your furnace making noise as it turns on, other noises are indicating your furnace needs immediate professional support.

Here are some of the most frequent furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating pros are here to assist with the best furnace repair in East Bernard, Texas.

1. Furnace Making a Banging Noise

You could have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These include gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy as time passes, so that’s why it’s critical to book yearly furnace maintenance with E.B. Air. One of the jobs our technicians do during this work is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes more time. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can discharge carbon monoxide, which is ordinarily released outdoors. This toxic gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, E.B. Air urges you to turn it off and calling us at 979-335-4262. Significant natural gas in your furnace or a broken heat exchanger are serious troubles that require fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide warm air around your house. If the ductwork wasn’t installed correctly or is getting dated, it can be noisy when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with E.B. Air at 979-335-4262 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually means there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or cold air throughout your space, and a capacitor, which turns on the motor. If either of these parts are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be due to something minor, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 979-335-4262 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to tell you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing could need to be lubed. We realize that maintenance often slips your mind, but our techs can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing noise, E.B. Air can assist you. It’s important to get loose ductwork fixed without delay, as it can result in comfort troubles in your home and inflate your energy bills.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Turn off your furnace off right away and call us at 979-335-4262 for assistance.
