When your furnace is running like it should, it should give warm air without making too much noise. While it’s common to hear your furnace making noise as it starts up, other disruptions are showing your furnace needs immediate professional help.

Here are some of the most frequent furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Hodgenville, Kentucky.

1. Furnace Making a Banging Noise

You might 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 may indicate there could be a few problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over the years, so that’s why it’s important to set annual furnace maintenance with Phelps Heating & Cooling, Inc.. One of the jobs our pros perform during this service is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can leak carbon monoxide, which is ordinarily emitted outdoors. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Phelps Heating & Cooling, Inc. advises turning it off and contacting us at 270-358-3167. Too much natural gas in your furnace or a broken heat exchanger are critical troubles that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move hot air across your residence. If the ductwork wasn’t installed properly or is getting old, it can be loud when your furnace runs. This could be the issue if your furnace makes a banging noise when it shuts off. Call Phelps Heating & Cooling, Inc. at 270-358-3167 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

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 issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cold air throughout your space, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something small, like an unsecure screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating pros at 270-358-3167 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing may need to be greased. We are aware that maintenance often slips your mind, but our technicians can get your furnace operating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent is loose. If you’ve checked your vents but are still hearing sound, Phelps Heating & Cooling, Inc. can assist you. It’s critical to get loose ductwork taken care of fast, since it can create comfort troubles in your home and drive up your utility expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise usually means there’s trouble with your furnace’s blower. Switch off your furnace off promptly and contact our pros at 270-358-3167 for assistance.
