1. Furnace Makes Banging or Knocking Sounds

You might have a critical problem 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 building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s important to schedule seasonal furnace maintenance with Myers Furnace Company. One of the tasks our pros do during this appointment is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise after ignition is delayed. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can leak carbon monoxide, which is ordinarily emitted outdoors. This hazardous gas can be deadly in large concentrations.

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

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver heated air throughout your house. If the ductwork wasn’t put in correctly or is getting dated, it can be loud when your furnace is on. 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 determine the problem.

2. Furnace Buzzes Constantly

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

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cooled air across your home, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be the result of something little, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 816-249-1619 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be greased. We know that maintenance sometimes slips your mind, but our pros can get your furnace running quietly again quickly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still sensing noise, Myers Furnace Company can assist you. It’s important to get loose ductwork fixed quickly, as it can make comfort problems in your house and inflate your energy bills.

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 often means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and reach us at 816-249-1619 for support.
