1. Furnace Making a Banging Noise

You might have a critical problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These involve gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s critical to set yearly furnace maintenance with Done Right Air. One of the things our pros do during this work is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The following gas buildup might crack your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can emit carbon monoxide, which is regularly released away from your home. This dangerous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Done Right Air urges you to turn it off and calling us at 414-208-9000. Significant natural gas in your furnace or a fractured heat exchanger are critical troubles that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide warm air around your residence. If the ductwork wasn’t designed properly or is getting old, it can be loud when your furnace is heating. This may be the issue if your furnace makes a banging noise when it shuts off. Contact Done Right Air at 414-208-9000 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

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 issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or cold air around your home, and a capacitor, which starts the motor. If either of these components 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 may be due to something small, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating specialists at 414-208-9000 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance often slips your mind, but our professionals can get your furnace heating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also hear whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still hearing noise, Done Right Air can assist you. It’s critical to get loose ductwork taken care of fast, since it can result in comfort troubles in your residence and inflate your energy bills.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s trouble with your furnace’s blower. Turn off your furnace off right away and reach our pros at 414-208-9000 for support.
