When your furnace is running like it should, it should give warm air without making too much noise. While it’s common to hear your furnace making noise as it turns on, other noises are signaling your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they might mean. If your furnace is making an atypical noise, our friendly heating pros are here to help with the best furnace repair in Beaverton, Oregon.

1. Furnace Makes a Banging Sound

You may have a critical situation 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 issue.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over the years, so that’s why it’s critical to book yearly furnace maintenance with All Solutions Heating & Cooling. One of the things our technicians perform during this work is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily vented outdoors. This toxic gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, All Solutions Heating & Cooling urges you to turn it off and contacting us at 971-245-2459. Significant natural gas in your furnace or a cracked heat exchanger are hazardous problems that should get prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move hot air throughout your home. If the ductwork wasn’t designed correctly or is getting old, it can be loud 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 determine the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or cold air throughout your house, and a capacitor, which triggers the motor. If either of these parts are failing, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be due to something little, like an unsecure screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 971-245-2459 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to tell you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing might need to be greased. We are aware that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s likely 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 looked at your vents but are still sensing whistling, All Solutions Heating & Cooling can assist you. It’s essential to get loose ductwork taken care of without delay, since it can create comfort issues in your house and drive up your energy expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Switch off your furnace off immediately and reach us at 971-245-2459 for support.
