When your furnace is working like it should, it should provide heat without making too much disruption. While it’s common to catch your furnace making noise as it starts up, other sounds are signaling your furnace should get immediate professional assistance.

Here are some of the most common furnace noises and what they could be indicating. If your furnace is making an atypical noise, our friendly heating professionals are here to assist with the best furnace repair in Portland, Oregon.

1. Furnace Making a Banging Noise

You could have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These include gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s important to set routine furnace maintenance with All Solutions Heating & Cooling. One of the jobs our professionals do during this appointment is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can leak carbon monoxide, which is ordinarily emitted outside. This hazardous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, All Solutions Heating & Cooling urges you to turn it off and calling us at 971-245-2459. Significant natural gas in your furnace or a broken heat exchanger are critical issues that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air around your house. If the ductwork wasn’t installed correctly or is getting old, 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. Call All Solutions Heating & Cooling at 971-245-2459 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the proper voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or chilly air throughout your home, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be due to something minor, like an unsecure screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 971-245-2459 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubricated. We are aware that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again quickly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still sensing noise, All Solutions Heating & Cooling can provide support. It’s critical to get loose ductwork taken care of quickly, because it can result in comfort problems in your home and drive up your gas expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Shut down your furnace off now and contact us at 971-245-2459 for help.
