When your furnace is operating correctly, it should provide heat without making too much disruption. While it’s normal to catch your furnace making noise as it begins running, other disruptions are indicating your furnace needs immediate professional assistance.

Here are some of the most common furnace noises and what they might be signaling. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Erie, Pennsylvania.

1. Furnace Makes a Banging Sound

You may have a serious issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be several problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s essential to set seasonal furnace maintenance with Patterson & Stirling. One of the things our pros perform during this work is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can emit carbon monoxide, which is ordinarily emitted outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Patterson & Stirling urges you to turn it off and calling us at 814-308-0416. Excessive natural gas in your furnace or a ruptured heat exchanger are dangerous problems that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver heated air around your home. If the ductwork wasn’t put in correctly or is getting dated, it can be loud when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Contact Patterson & Stirling at 814-308-0416 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace depends on an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or cold air throughout your space, and a capacitor, which turns on the motor. If either of these pieces are going out, 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 due to something minor, like an unfastened screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating pros at 814-308-0416 for assistance.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to alert you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing may need to be greased. We know that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still sensing sound, Patterson & Stirling can assist you. It’s essential to get loose ductwork taken care of quickly, since it can create comfort issues in your residence and drive up your heating 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 noise often means there’s trouble with your furnace’s blower. Shut down your furnace off now and reach us at 814-308-0416 for help.
