When your furnace is running correctly, it should give warm air without making too much noise. While it’s normal to notice your furnace making noise as it begins running, other disruptions are signaling your furnace requires immediate professional help.

Here are some of the most frequent furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating specialists are here to assist with the best furnace repair in Port St. Lucie, Florida.

1. Furnace Making a Banging Noise

You might 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 can signal there could be a couple of problems. These range from gas increasing 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 essential to set yearly furnace maintenance with Custom Air Systems Inc. One of the tasks our pros perform during this service is clean your furnace’s burners. When this piece gets grimy, 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 changes into heat. Any breaks in it can leak carbon monoxide, which is regularly vented outside. This dangerous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Custom Air Systems Inc recommends turning it off and contacting us at 772-247-2283. Significant natural gas in your furnace or a broken heat exchanger are dangerous issues that should get prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver heated air across your residence. If the ductwork wasn’t put in correctly or is getting old, it can be noisy when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Contact Custom Air Systems Inc at 772-247-2283 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you notice 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 work on the right voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or cold air around your house, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be related to something small, like an unfastened screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and contacting our heating professionals at 772-247-2283 for support.

4. Furnace Making a Squealing Noise

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

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still sensing noise, Custom Air Systems Inc can help. It’s critical to get loose ductwork repaired without delay, as it can make comfort troubles in your house and drive up your utility expenses.

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 racket typically means there’s trouble with your furnace’s blower. Switch off your furnace off right away and call our professionals at 772-247-2283 for assistance.
