When your furnace is working properly, it should deliver heat without generating too much disruption. While it’s expected to hear 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 frequent furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating pros are here to help with the best furnace repair in Palm Coast, Florida.

1. Furnace Making a Banging Noise

You could have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over time, so that’s why it’s critical to schedule routine furnace maintenance with Cooks Air Conditioning and Heating Specialists. One of the tasks our techs 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 if ignition takes longer than normal. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can discharge carbon monoxide, which is regularly vented outside. This toxic gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Cooks Air Conditioning and Heating Specialists recommends turning it off and reaching us at 386-313-8766. Excessive natural gas in your furnace or a ruptured heat exchanger are critical issues that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide warm air around your house. If the ductwork wasn’t installed right or is aging, it can make a lot of noise when your furnace runs. This could be the issue if your furnace makes a banging noise when it shuts off. Call Cooks Air Conditioning and Heating Specialists at 386-313-8766 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or chilly air throughout your space, 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 can be due to something little, like a loose screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 386-313-8766 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We know that maintenance frequently slips your mind, but our techs can get your furnace running quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve examined your vents but are still sensing sound, Cooks Air Conditioning and Heating Specialists can provide support. It’s important to get loose ductwork repaired quickly, because it can create comfort troubles in your house and increase your gas costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s a problem with your furnace’s blower. Shut down your furnace off immediately and contact us at 386-313-8766 for support.
