When your furnace is working like it should, it should provide warmth without making too much sound. While it’s expected to hear your furnace making noise as it turns on, other disruptions are indicating your furnace needs immediate professional assistance.

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 assist with the best furnace repair in Neptune City, New Jersey.

1. Furnace Makes a Banging Sound

You may have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These include gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s important to set annual furnace maintenance with Aggressive Mechanical. One of the things our pros perform during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The following gas buildup might break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is normally released away from your home. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Aggressive Mechanical urges you to turn it off and contacting us at 732-806-5536. Significant natural gas in your furnace or a fractured heat exchanger are hazardous problems that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air throughout your house. If the ductwork wasn’t installed properly or is aging, it can be noisy when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Aggressive Mechanical at 732-806-5536 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually is telling you there’s an electrical problem, 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 is loose, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or chilly air around your rooms, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be related to something little, like an unsecure screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 732-806-5536 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to tell you it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We know that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also notice whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Aggressive Mechanical can help. It’s essential to get loose ductwork fixed quickly, as it can make comfort issues in your home and drive up your utility costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Shut down your furnace off now and contact our professionals at 732-806-5536 for help.
