When your furnace is operating like it should, it should give heat without creating too much noise. While it’s normal to catch your furnace making noise as it begins running, other disruptions are showing your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Omaha, Nebraska.

1. Furnace Makes Banging or Knocking Sounds

You may have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over time, so that’s why it’s essential to schedule yearly furnace maintenance with Interstate Heating & Air Conditioning. One of the things our pros perform during this service is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can leak carbon monoxide, which is ordinarily released outside. This dangerous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Interstate Heating & Air Conditioning urges you to turn it off and reaching us at 402-509-5940. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous issues that require immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move hot air throughout your residence. If the ductwork wasn’t put in properly or is getting dated, it can make a lot of noise when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Call Interstate Heating & Air Conditioning at 402-509-5940 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cooled air across your space, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be related to something small, like an unfastened screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating pros at 402-509-5940 for support.

4. Furnace Squeals

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

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also notice whistling while the furnace is on if a floor vent isn’t secure. If you’ve checked your vents but are still hearing noise, Interstate Heating & Air Conditioning can help. It’s essential to get loose ductwork taken care of without delay, as it can create comfort problems in your residence and inflate your heating expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound frequently means there’s trouble with your furnace’s blower. Switch off your furnace off immediately and contact us at 402-509-5940 for support.
