When your furnace is running correctly, it should deliver heat without making too much disruption. While it’s normal to hear your furnace making noise as it starts up, other disruptions are signaling your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making an odd noise, our friendly heating specialists are here to help with the best furnace repair in Genoa, Illinois.

1. Furnace Makes Banging or Knocking Sounds

You may have an urgent issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be several problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy as time passes, so that’s why it’s essential to schedule yearly furnace maintenance with Assured Appliance & Heating & Air. One of the tasks our professionals do during this appointment is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise if ignition is delayed. The resulting gas buildup might crack your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can leak carbon monoxide, which is normally released outside. This hazardous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Assured Appliance & Heating & Air urges you to turn it off and calling us at 847-306-8990. Too much natural gas in your furnace or a fractured heat exchanger are hazardous problems that necessitate fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver hot air throughout your home. If the ductwork wasn’t designed right or is getting dated, it can be noisy when your furnace runs. This can be the case if your furnace makes a banging noise when it shuts off. Contact Assured Appliance & Heating & Air at 847-306-8990 and we’ll figure out 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 frequently is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cooled air throughout your rooms, and a capacitor, which turns on the motor. If either of these pieces are going out, 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 minor, like an unsecure screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating specialists at 847-306-8990 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubed. We realize that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may 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 hearing noise, Assured Appliance & Heating & Air can assist you. It’s critical to get loose ductwork taken care of fast, since it can make comfort troubles in your home and increase your utility expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Turn off your furnace off right away and contact us at 847-306-8990 for assistance.
