When your furnace is operating properly, it should provide warmth without creating too much noise. While it’s common to notice your furnace making noise as it turns on, other sounds are signaling your furnace requires immediate professional help.
Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Hodgenville, Kentucky.
1. Furnace Makes a Banging Sound
You might have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a few problems. These include gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s important to book seasonal furnace maintenance with Phelps Heating & Cooling, Inc.. One of the things our pros do during this appointment is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise if ignition is delayed. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can leak carbon monoxide, which is normally released away from your home. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Phelps Heating & Cooling, Inc. advises turning it off and reaching us at 270-358-3167. Excessive natural gas in your furnace or a ruptured heat exchanger are hazardous issues that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide heated air throughout your home. If the ductwork wasn’t put in right or is getting dated, it can be loud when your furnace runs. This may 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 Buzzes Constantly
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often 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 right voltage. If wires or the box isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or cold air around your rooms, and a capacitor, which turns on 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 small, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and calling our heating professionals at 270-358-3167 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to get your attention it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubricated. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace operating quietly again quickly.
5. Furnace Whistles
When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve checked your vents but are still hearing sound, Phelps Heating & Cooling, Inc. can help. It’s critical to get loose ductwork repaired fast, since it can result in comfort issues in your home and inflate your gas costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s trouble with your furnace’s blower. Turn off your furnace off instantly and contact our professionals at 270-358-3167 for help.
