When your furnace is working correctly, it should provide warm air without generating too much disruption. While it’s expected to notice your furnace making noise as it turns on, other disruptions are signaling your furnace should get immediate professional assistance.
Here are some of the most reported furnace noises and what they can be indicating. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Moline, Illinois.
1. Furnace Makes a Banging Sound
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 becomes grimy as time passes, so that’s why it’s essential to book yearly furnace maintenance with Freed Heating & Air Conditioning. One of the tasks our pros perform during this appointment is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can leak carbon monoxide, which is ordinarily vented away from your home. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Freed Heating & Air Conditioning urges you to turn it off and contacting us at 309-323-9584. Significant natural gas in your furnace or a cracked heat exchanger are dangerous problems that necessitate fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move warm air around your residence. If the ductwork wasn’t put in properly or is getting old, it can make a lot of noise when your furnace is on. This might be the problem if your furnace makes a banging noise when it shuts off. Contact Freed Heating & Air Conditioning at 309-323-9584 and we’ll determine the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often indicates an electrical problem, 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 needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or cooled air around your rooms, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace switches on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it can be due to something small, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 309-323-9584 for help.
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 attempting to alert you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubed. We realize that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also hear whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still sensing sound, Freed Heating & Air Conditioning can help. It’s essential to get loose ductwork taken care of quickly, since it can make comfort problems in your house and inflate your utility bills.
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 sound frequently means there’s an issue with your furnace’s blower. Turn off your furnace off immediately and call our professionals at 309-323-9584 for assistance.
