When your furnace is running like it should, it should deliver heat without creating too much sound. While it’s common to hear your furnace making noise as it turns on, other disruptions are signaling your furnace requires immediate professional support.

Here are some of the most frequent furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating professionals are here to assist with the best furnace repair in Thousand Palms, California.

1. Furnace Makes Banging or Knocking Sounds

You could have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a couple of problems. These involve gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s essential to book seasonal furnace maintenance with Marios Air Conditioning. One of the jobs our professionals do during this appointment is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can emit carbon monoxide, which is regularly vented outside. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Marios Air Conditioning recommends turning it off and calling us at 760-314-4766. Too much natural gas in your furnace or a ruptured heat exchanger are critical issues that should get fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air around your home. If the ductwork wasn’t designed properly or is getting old, it can make a lot of noise when your furnace runs. This may be the issue if your furnace makes a banging noise when it shuts off. Contact Marios Air Conditioning at 760-314-4766 and we’ll determine 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 is telling you there’s 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 needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cold air around your rooms, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be the result of something small, like an unfastened screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 760-314-4766 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing may need to be greased. We know that maintenance often slips your mind, but our professionals can get your furnace heating 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 notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve checked your vents but are still noticing noise, Marios Air Conditioning can assist you. It’s critical to get loose ductwork repaired fast, because it can make comfort issues in your residence and drive up your utility costs.

6. Furnace Makes a Loud, Unpleasant 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. Turn off your furnace off now and call our pros at 760-314-4766 for help.
