When your furnace is running like it should, it should provide warm air without making too much disruption. While it’s expected to notice your furnace making noise as it turns on, other sounds are indicating your furnace should get immediate professional help.
Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Reinholds, Pennsylvania.
1. Furnace Making a Banging Noise
You could have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These range from gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy as time passes, so that’s why it’s important to set yearly furnace maintenance with County Line Mechanical LLC. One of the tasks our techs perform during this appointment is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can leak carbon monoxide, which is ordinarily emitted away from your home. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, County Line Mechanical LLC recommends turning it off and contacting us at 717-216-0846. Too much natural gas in your furnace or a broken heat exchanger are hazardous problems that require fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move warm air throughout your home. If the ductwork wasn’t designed right or is getting dated, it can be loud when your furnace runs. This could be the problem 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 Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically means there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the proper voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or cooled air throughout your rooms, and a capacitor, which triggers the motor. If either of these pieces are fading, 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 due to something minor, like an unsecure screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating professionals at 717-216-0846 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We know that maintenance often slips your mind, but our techs can get your furnace running quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still noticing sound, County Line Mechanical LLC can provide support. It’s essential to get loose ductwork taken care of quickly, as it can make comfort problems in your house and inflate your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal sound usually means there’s trouble with your furnace’s blower. Switch off your furnace off right away and contact our professionals at 717-216-0846 for support.
