1. Furnace Makes Banging or Knocking Sounds

You may have an urgent problem 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 a few problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty as time passes, so that’s why it’s critical to set seasonal furnace maintenance with Assured Appliance & Heating & Air. One of the tasks our techs do during this service is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise after ignition is delayed. The following gas buildup may crack your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can emit carbon monoxide, which is normally released away from your home. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Assured Appliance & Heating & Air advises turning it off and contacting us at 847-306-8990. Significant natural gas in your furnace or a ruptured heat exchanger are serious issues that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver heated air around your residence. If the ductwork wasn’t put in right or is getting dated, it can be loud when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Call 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 often indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or chilly air around your space, and a capacitor, which triggers the motor. If either of these components are going out, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be related to something little, like an unsecure screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and calling our heating pros at 847-306-8990 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

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 down or a bearing might need to be greased. We are aware that maintenance often slips your mind, but our technicians can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing whistling, Assured Appliance & Heating & Air can assist you. It’s critical to get loose ductwork repaired fast, as it can make comfort issues in your home and inflate your gas 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 an issue with your furnace’s blower. Switch off your furnace off instantly and reach our professionals at 847-306-8990 for assistance.
