When your furnace is operating like it should, it should give heat without generating too much noise. While it’s expected to notice your furnace making noise as it begins running, other disruptions are signaling your furnace should get immediate professional assistance.

Here are some of the most common furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating pros are here to help with the best furnace repair in Long Island, New York.

1. Furnace Making a Banging Noise

You might have an urgent 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 increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s essential to schedule routine furnace maintenance with Airmax Long Island. One of the things our techs complete during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can emit carbon monoxide, which is regularly vented outdoors. This toxic gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Airmax Long Island advises turning it off and contacting us at 631-737-5566. Significant natural gas in your furnace or a ruptured heat exchanger are dangerous issues that should get immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move warm air throughout your house. If the ductwork wasn’t put in correctly or is getting old, it can be loud when your furnace runs. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Airmax Long Island at 631-737-5566 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently indicates an electrical problem, 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 needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cold air around your house, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be the result of something small, like an unsecure screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and calling our heating pros at 631-737-5566 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubricated. We know that maintenance often slips your mind, but our professionals can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent is loose. If you’ve examined your vents but are still hearing whistling, Airmax Long Island can provide support. It’s essential to get loose ductwork fixed quickly, as it can make comfort problems in your home and increase your utility costs.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound usually means there’s trouble with your furnace’s blower. Shut down your furnace off right away and reach us at 631-737-5566 for help.
