When your furnace is operating correctly, it should deliver heat without creating too much noise. While it’s normal to catch your furnace making noise as it turns on, other noises are signaling your furnace should get immediate professional help.

Here are some of the most reported furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Belton, Missouri.

1. Furnace Makes a Banging Sound

You could have a critical situation on your hands if you’re hearing 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 accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s essential to set annual furnace maintenance with Myers Furnace Company. One of the things our pros do during this service is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can discharge carbon monoxide, which is normally released outdoors. This hazardous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Myers Furnace Company recommends turning it off and contacting us at 816-249-1619. Significant natural gas in your furnace or a broken heat exchanger are dangerous troubles that necessitate prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air throughout your home. If the ductwork wasn’t put in correctly or is getting dated, it can be loud when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Call Myers Furnace Company at 816-249-1619 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to operate on the right voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cooled air throughout your house, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be the result of something minor, like an unfastened screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and calling our heating specialists at 816-249-1619 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing may need to be greased. We know that maintenance often slips your mind, but our technicians can get your furnace operating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also be aware of whistling while the furnace is operating if a floor vent is loose. If you’ve checked your vents but are still hearing sound, Myers Furnace Company can help. It’s critical to get loose ductwork fixed quickly, because it can create comfort problems in your residence and increase your heating bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Switch off your furnace off right away and contact us at 816-249-1619 for support.
