When your furnace is running correctly, it should give warm air without generating too much disruption. While it’s expected to notice your furnace making noise as it turns on, other disruptions are signaling your furnace needs immediate professional assistance.

Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making a weird noise, our friendly heating professionals are here to assist with the best furnace repair in Santa Clarita, California.

1. Furnace Makes Banging or Knocking Sounds

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 can mean there could be a few problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s critical to schedule annual furnace maintenance with Verona HVAC. One of the jobs our technicians complete during this work is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can leak carbon monoxide, which is ordinarily emitted away from your home. This toxic gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Verona HVAC urges you to turn it off and reaching us at 661-475-1042. Excessive natural gas in your furnace or a ruptured heat exchanger are serious issues that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air throughout your home. If the ductwork wasn’t put in right or is getting dated, it can make a lot of noise when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Call Verona HVAC at 661-475-1042 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air throughout your space, and a capacitor, which turns on the motor. If either of these parts are fading, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something little, like an unfastened screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and calling our heating pros at 661-475-1042 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to alert you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be greased. We realize that maintenance often slips your mind, but our pros can get your furnace running quietly again fast.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also hear whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still sensing sound, Verona HVAC can help. It’s critical to get loose ductwork repaired fast, because it can create comfort troubles in your residence and drive up your utility bills.

6. Furnace Making a Grinding Noise

It’s not a good 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 promptly and reach our pros at 661-475-1042 for support.
