When your furnace is running properly, it should provide heat without generating too much disruption. While it’s common to notice your furnace making noise as it starts up, other noises are indicating your furnace should get immediate professional support.

Here are some of the most reported furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Port Orchard, Washington.

1. Furnace Makes Banging or Knocking Sounds

You might have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal 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 filthy over time, so that’s why it’s important to set routine furnace maintenance with Air Masters Heating & Cooling. One of the jobs our professionals perform during this service is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise if ignition is delayed. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can emit carbon monoxide, which is regularly emitted outdoors. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Air Masters Heating & Cooling urges you to turn it off and contacting us at 360-205-7115. Excessive natural gas in your furnace or a ruptured heat exchanger are critical problems that should get prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air around your house. If the ductwork wasn’t designed right or is getting old, it can make a lot of noise when your furnace is on. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Air Masters Heating & Cooling at 360-205-7115 and we’ll determine 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 often means 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 isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or chilly air throughout your home, and a capacitor, which starts the motor. If either of these components 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 may be due to something small, like an unsecure screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating professionals at 360-205-7115 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubricated. We realize that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve checked your vents but are still sensing noise, Air Masters Heating & Cooling can provide support. It’s essential to get loose ductwork repaired quickly, because it can create comfort issues in your residence and drive up your gas expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Shut down your furnace off now and call our pros at 360-205-7115 for support.
