When your furnace is running like it should, it should provide warm air without making too much sound. While it’s expected to catch your furnace making noise as it begins running, other noises are indicating your furnace should get immediate professional assistance.

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

1. Furnace Making a Banging Noise

You may have an urgent issue on your hands if you’re noticing 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 range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s critical to schedule yearly furnace maintenance with Air-Right Energy Design. One of the things our pros do during this service is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise after ignition is delayed. The following gas buildup might break your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can discharge carbon monoxide, which is ordinarily released outdoors. This hazardous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Air-Right Energy Design recommends turning it off and reaching us at 703-260-1148. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous problems that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air around your residence. If the ductwork wasn’t installed correctly or is aging, it can be noisy when your furnace is heating. This might be the case if your furnace makes a banging noise when it shuts off. Call Air-Right Energy Design at 703-260-1148 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

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

Your furnace depends on an internal transformer to operate on the right 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 moves warm or cooled air throughout your rooms, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be related to something minor, like an unsecure screw, or something serious, like a broken component. In either case, we advise shutting your furnace off and calling our heating professionals at 703-260-1148 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to alert you it could use some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing may need to be greased. We are aware 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 typically due to an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve examined your vents but are still hearing whistling, Air-Right Energy Design can assist you. It’s important to get loose ductwork taken care of fast, as it can make comfort issues in your house and increase your utility expenses.

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 racket usually means there’s an issue with your furnace’s blower. Switch off your furnace off promptly and reach us at 703-260-1148 for help.
