When your furnace is running like it should, it should provide warmth without creating too much sound. While it’s common to notice your furnace making noise as it starts up, other noises are indicating your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making an atypical noise, our friendly heating professionals are here to assist with the best furnace repair in Reinholds, Pennsylvania.

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 may signal there could be a couple of problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy as time passes, so that’s why it’s important to schedule annual furnace maintenance with County Line Mechanical LLC. One of the things our pros perform during this appointment is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise after ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can discharge carbon monoxide, which is regularly vented outside. This hazardous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, County Line Mechanical LLC urges you to turn it off and contacting us at 717-216-0846. Significant natural gas in your furnace or a ruptured heat exchanger are critical problems that should get fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide warm air throughout your home. If the ductwork wasn’t designed right or is getting old, it can be noisy when your furnace is heating. This could be the case if your furnace makes a banging noise when it shuts off. Call County Line Mechanical LLC at 717-216-0846 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace uses an internal transformer to run on the proper 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 hot or cold air throughout your space, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be related to something minor, like an unsecure screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 717-216-0846 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be lubed. We are aware that maintenance often slips your mind, but our professionals can get your furnace heating quietly again rapidly.

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 notice whistling while the furnace is running if a floor vent is loose. If you’ve examined your vents but are still noticing sound, County Line Mechanical LLC can help. It’s essential to get loose ductwork repaired without delay, since it can make comfort issues in your house and increase your utility bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive 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 instantly and call our pros at 717-216-0846 for assistance.
