When your furnace is operating like it should, it should give warm air without making too much disruption. While it’s normal to hear your furnace making noise as it turns on, other noises are indicating your furnace should get immediate professional support.

Here are some of the most common furnace noises and what they might be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Booneville, Mississippi.

1. Furnace Makes Banging or Knocking Sounds

You could have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a couple of problems. These involve gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over the years, so that’s why it’s essential to schedule seasonal furnace maintenance with Booneville Heating & Cooling. One of the tasks our techs complete 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 ensuing gas buildup might break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can leak carbon monoxide, which is normally released outside. This toxic gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Booneville Heating & Cooling urges you to turn it off and contacting us at 662-269-8716. Too much natural gas in your furnace or a fractured heat exchanger are dangerous issues that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air across your residence. If the ductwork wasn’t designed right or is getting dated, it can make a lot of noise when your furnace is on. This could be the issue if your furnace makes a banging noise when it shuts off. Call Booneville Heating & Cooling at 662-269-8716 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or chilly air throughout your rooms, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be the result of something little, like an unfastened screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating professionals at 662-269-8716 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to get your attention it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing might need to be greased. We know that maintenance often slips your mind, but our techs can get your furnace heating 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 may also be aware of whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still sensing noise, Booneville Heating & Cooling can help. It’s important to get loose ductwork repaired fast, because it can result in comfort troubles in your house and increase your gas bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Switch off your furnace off now and contact our professionals at 662-269-8716 for assistance.
