When your furnace is working like it should, it should provide heat without generating too much noise. While it’s expected to notice your furnace making noise as it turns on, other disruptions are signaling your furnace needs immediate professional assistance.
Here are some of the most reported furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Dresden, ON.
1. Furnace Making a Banging Noise
You might have a critical problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy over the years, so that’s why it’s critical to schedule annual furnace maintenance with McFadden Heating & Cooling. One of the tasks our professionals perform during this service is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can leak carbon monoxide, which is normally emitted away from your home. This dangerous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, McFadden Heating & Cooling advises turning it off and reaching us at 1-866-781-0111. Too much natural gas in your furnace or a cracked heat exchanger are dangerous issues that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide hot air around your house. If the ductwork wasn’t designed properly or is aging, it can make a lot of noise when your furnace is heating. This could be the case if your furnace makes a banging noise when it shuts off. Contact McFadden Heating & Cooling at 1-866-781-0111 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually is telling you there’s an electrical problem, 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 isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or cold air around your space, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be the result of something small, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 1-866-781-0111 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubricated. We know that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting 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 on if a floor vent isn’t tight. If you’ve checked your vents but are still hearing whistling, McFadden Heating & Cooling can assist you. It’s critical to get loose ductwork taken care of fast, since it can create comfort troubles in your residence and inflate your heating 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 noise usually means there’s trouble with your furnace’s blower. Turn off your furnace off now and contact us at 1-866-781-0111 for assistance.
