1. Furnace Makes Banging or Knocking Sounds
You could have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These range from gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over the years, so that’s why it’s essential to set annual furnace maintenance with JTech Mechanical. One of the tasks our pros complete during this work is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup may break your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can emit carbon monoxide, which is normally vented outside. This toxic gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, JTech Mechanical advises turning it off and reaching us at 281-231-8768. Too much natural gas in your furnace or a fractured heat exchanger are serious troubles that should get prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver warm air throughout your home. If the ductwork wasn’t put in correctly or is getting old, it can be noisy when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Call JTech Mechanical at 281-231-8768 and we’ll determine the problem.
2. Furnace Buzzes Constantly
If you observe 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 uses an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or chilly air around your residence, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be related to something minor, like an unsecure screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and calling our heating professionals at 281-231-8768 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to tell you it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubed. We know that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still sensing sound, JTech Mechanical can assist you. It’s essential to get loose ductwork repaired fast, since it can create comfort troubles in your residence and increase your gas costs.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s a problem with your furnace’s blower. Turn off your furnace off right away and reach our pros at 281-231-8768 for assistance.
