1. Furnace Making a Banging Noise
You could have a serious problem 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 a few problems. These range from gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy as time passes, so that’s why it’s critical to schedule annual furnace maintenance with MPC Heating & Cooling. One of the things our pros do during this work is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup may break your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can emit carbon monoxide, which is ordinarily released outside. This dangerous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, MPC Heating & Cooling urges you to turn it off and contacting us at 308-832-4321. Excessive natural gas in your furnace or a broken heat exchanger are critical troubles that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver heated air across your house. If the ductwork wasn’t put in right or is getting old, it can make a lot of noise when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Contact MPC Heating & Cooling at 308-832-4321 and we’ll determine 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 issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or cooled air throughout your space, and a capacitor, which turns on 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 may be the result of something minor, like an unsecure screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 308-832-4321 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our pros 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 frequently the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still hearing whistling, MPC Heating & Cooling can assist you. It’s critical to get loose ductwork fixed without delay, as it can result in comfort issues in your house and inflate your gas costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal noise often means there’s a problem with your furnace’s blower. Switch off your furnace off now and reach our professionals at 308-832-4321 for support.
