When your furnace is working like it should, it should deliver heat without generating too much disruption. While it’s normal to notice your furnace making noise as it turns on, other noises are indicating your furnace needs immediate professional support.

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 professionals are here to assist with the best furnace repair in Huntsville, Alabama.

1. Furnace Making a Banging Noise

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

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s essential to set seasonal furnace maintenance with All Weather Heating & Air Conditioning Inc. One of the tasks our technicians perform during this work is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can leak carbon monoxide, which is normally vented outside. This dangerous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, All Weather Heating & Air Conditioning Inc urges you to turn it off and contacting us at 256-801-4701. Significant natural gas in your furnace or a ruptured heat exchanger are dangerous troubles that require fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air across your residence. If the ductwork wasn’t installed right or is getting old, it can be noisy when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with All Weather Heating & Air Conditioning Inc at 256-801-4701 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air across your home, and a capacitor, which starts the motor. If either of these components are fading, 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 can be related to something minor, like an unfastened screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 256-801-4701 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing may need to be greased. We realize 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 noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also be aware of whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing sound, All Weather Heating & Air Conditioning Inc can help. It’s critical to get loose ductwork repaired without delay, since it can make comfort problems in your residence and drive up your heating costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and call our professionals at 256-801-4701 for assistance.
