1. Furnace Makes Banging or Knocking Sounds
You might have a critical problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These include gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty as time passes, so that’s why it’s critical to book yearly furnace maintenance with Lakeside Heating & Air. One of the tasks our techs complete during this appointment is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The resulting gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can leak carbon monoxide, which is normally vented outside. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Lakeside Heating & Air urges you to turn it off and reaching us at 509-284-4265. Too much natural gas in your furnace or a fractured heat exchanger are dangerous issues that necessitate immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air across your home. If the ductwork wasn’t put in properly or is getting old, it can be loud when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Call Lakeside Heating & Air at 509-284-4265 and we’ll figure out the problem.
2. Furnace Buzzes Constantly
If you observe your furnace making a buzzing noise, don’t hesitate to call 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 operate on the correct voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or chilly air across your space, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace starts.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be related to something little, like a loose screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and calling our heating professionals at 509-284-4265 for support.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s running, 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 could need to be lubricated. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Lakeside Heating & Air can help. It’s critical to get loose ductwork fixed quickly, because it can create comfort issues in your residence and drive up your gas costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Turn off your furnace off right away and reach our pros at 509-284-4265 for support.
