1. Furnace Makes Banging or Knocking Sounds
You might have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be several problems. These range from gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over the years, so that’s why it’s essential to schedule annual furnace maintenance with McFadden Heating & Cooling. One of the things our professionals perform during this appointment is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes more time. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can discharge carbon monoxide, which is normally released outdoors. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, McFadden Heating & Cooling urges you to turn it off and contacting us at 519-683-2339. Excessive natural gas in your furnace or a ruptured heat exchanger are hazardous troubles that should get fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move warm air around your house. If the ductwork wasn’t put in properly or is getting dated, it can be noisy when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Call McFadden Heating & Cooling at 519-683-2339 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or chilly air throughout your house, and a capacitor, which starts the motor. If either of these parts are fading, they will buzz when the furnace starts.
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 serious, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating pros at 519-683-2339 for assistance.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be greased. We realize that maintenance sometimes slips your mind, but our professionals 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 notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing sound, McFadden Heating & Cooling can provide support. It’s critical to get loose ductwork taken care of without delay, because it can create comfort issues in your house and increase your gas expenses.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s a problem with your furnace’s blower. Shut down your furnace off instantly and call us at 519-683-2339 for assistance.
