When your furnace is working like it should, it should provide heat without creating too much sound. While it’s normal to catch your furnace making noise as it turns on, other disruptions are signaling your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Laurel, Maryland.

1. Furnace Making a Banging Noise

You might have a serious 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 several problems. These involve gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over time, so that’s why it’s important to schedule annual furnace maintenance with H&C Heating and Cooling. One of the things our pros perform during this appointment is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can emit carbon monoxide, which is regularly released away from your home. This dangerous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, H&C Heating and Cooling urges you to turn it off and contacting us at 301-960-3247. Excessive natural gas in your furnace or a ruptured heat exchanger are critical troubles that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air across your residence. If the ductwork wasn’t installed right or is getting dated, it can make a lot of noise when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Contact H&C Heating and Cooling at 301-960-3247 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

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

Your furnace uses an internal transformer to work on the correct voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or chilly air across your residence, and a capacitor, which starts the motor. If either of these components are going out, 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 related to something minor, like an unfastened screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 301-960-3247 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing might need to be lubricated. We are aware that maintenance often slips your mind, but our pros can get your furnace running quietly again quickly.

5. Furnace Whistles

When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You could also hear whistling while the furnace is on if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing noise, H&C Heating and Cooling can help. It’s essential to get loose ductwork fixed quickly, as it can result in comfort problems in your home and inflate your energy expenses.

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 noise typically means there’s a problem with your furnace’s blower. Switch off your furnace off now and call our professionals at 301-960-3247 for help.
