When your furnace is working correctly, it should deliver heat without making too much noise. While it’s expected to catch your furnace making noise as it turns on, other disruptions are showing your furnace needs immediate professional assistance.

Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to help with the best furnace repair in Santa Clarita, California.

1. Furnace Makes Banging or Knocking Sounds

You may have a serious situation on your hands if you’re detecting 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 increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s important to schedule annual furnace maintenance with Verona HVAC. One of the jobs our professionals do during this appointment is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup might crack your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can leak carbon monoxide, which is normally emitted away from your home. This hazardous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Verona HVAC urges you to turn it off and calling us at 818-306-3387. Too much natural gas in your furnace or a cracked heat exchanger are serious troubles that should get fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air around your house. If the ductwork wasn’t installed properly or is aging, it can be loud when your furnace runs. This can be the case if your furnace makes a banging noise when it shuts off. Get in touch with Verona HVAC at 818-306-3387 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box isn’t tight enough, you may 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 residence, and a capacitor, which triggers the motor. If either of these components 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 related to something small, like a loose screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating specialists at 818-306-3387 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to alert you it could use 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 greased. We are aware that maintenance often slips your mind, but our technicians can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still sensing whistling, Verona HVAC can provide support. It’s critical to get loose ductwork repaired fast, because it can create comfort problems in your home and drive up your energy expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s a problem with your furnace’s blower. Turn off your furnace off right away and reach our pros at 818-306-3387 for support.
