When your furnace is working like it should, it should deliver warm air without creating too much disruption. While it’s expected to notice your furnace making noise as it begins running, other sounds are indicating your furnace should get immediate professional support.
Here are some of the most common furnace noises and what they could mean. If your furnace is making an odd noise, our friendly heating professionals are here to help with the best furnace repair in Wilmington, Delaware.
1. Furnace Making a Banging Noise
You could have a serious problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be several problems. These range from gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over the years, so that’s why it’s important to set yearly furnace maintenance with Brandywine Heating & Air. One of the tasks our technicians perform during this service is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup might break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can leak carbon monoxide, which is ordinarily released outdoors. This toxic gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Brandywine Heating & Air urges you to turn it off and calling us at 302-261-3596. Excessive natural gas in your furnace or a cracked heat exchanger are serious troubles that should get fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air around your residence. If the ductwork wasn’t put in right or is getting dated, it can be noisy when your furnace runs. This can be the case if your furnace makes a banging noise when it shuts off. Contact Brandywine Heating & Air at 302-261-3596 and we’ll pinpoint 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 typically indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes warm or cold air throughout your space, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace switches on.
3. Furnace Rattles
If your furnace is making a rattling noise, it could be due to something small, like an unsecure screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 302-261-3596 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to alert you it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We realize that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Brandywine Heating & Air can help. It’s essential to get loose ductwork fixed fast, because it can create comfort problems in your house and drive up your gas expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound frequently means there’s an issue with your furnace’s blower. Switch off your furnace off promptly and call our pros at 302-261-3596 for support.
