When your furnace is operating properly, it should deliver heat without making too much disruption. While it’s common to catch your furnace making noise as it turns on, other noises are indicating your furnace requires immediate professional support.
Here are some of the most common furnace noises and what they can be signaling. If your furnace is making a strange noise, our friendly heating professionals are here to help with the best furnace repair in Erie, PA.
1. Furnace Making a Banging Noise
You may 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 several problems. These range from gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s important to set routine furnace maintenance with Patterson & Stirling Inc. One of the things our technicians do during this appointment is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes more time. The following gas buildup can break your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can discharge carbon monoxide, which is ordinarily released outside. This dangerous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Patterson & Stirling Inc urges you to turn it off and reaching us at 814-308-0416. Excessive natural gas in your furnace or a broken heat exchanger are serious troubles that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air throughout your house. If the ductwork wasn’t installed right 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. Contact Patterson & Stirling Inc at 814-308-0416 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 frequently means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cooled air across your house, and a capacitor, which starts the motor. If either of these pieces 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 could be the result of something small, like an unsecure screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and calling our heating professionals at 814-308-0416 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to tell you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be dilapidated or a bearing could need to be lubed. We are aware that maintenance often slips your mind, but our technicians can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent is loose. If you’ve examined your vents but are still sensing whistling, Patterson & Stirling Inc can assist you. It’s critical to get loose ductwork taken care of without delay, because it can create comfort problems in your house and drive up your utility bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s an issue with your furnace’s blower. Switch off your furnace off now and contact our pros at 814-308-0416 for help.
