When your furnace is working like it should, it should give heat without making too much noise. While it’s common to hear your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional assistance.

Here are some of the most frequent furnace noises and what they could mean. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Erie, Pennsylvania.

1. Furnace Making a Banging Noise

You may have a critical issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These involve gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over the years, so that’s why it’s essential to book routine furnace maintenance with Patterson & Stirling. One of the things our professionals perform during this appointment is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can discharge carbon monoxide, which is normally vented away from your home. This dangerous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Patterson & Stirling advises turning it off and contacting us at 814-308-0416. Too much natural gas in your furnace or a ruptured heat exchanger are critical issues that should get prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air around your residence. If the ductwork wasn’t put in correctly or is aging, it can be noisy when your furnace is heating. This can be the case if your furnace makes a banging noise when it shuts off. Call Patterson & Stirling at 814-308-0416 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, 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 throughout your space, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be the result of something minor, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and calling our heating pros at 814-308-0416 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be greased. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace heating quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting 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 on if a floor vent isn’t secure. If you’ve examined your vents but are still noticing whistling, Patterson & Stirling can assist you. It’s important to get loose ductwork taken care of quickly, because it can create comfort issues in your house and drive up your utility expenses.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice 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 immediately and contact us at 814-308-0416 for support.
