When your furnace is operating like it should, it should deliver warmth without generating too much disruption. While it’s expected to catch your furnace making noise as it turns on, other noises are showing your furnace needs immediate professional help.
Here are some of the most common furnace noises and what they can be indicating. If your furnace is making a weird noise, our friendly heating pros are here to assist with the best furnace repair in Bend, Oregon.
1. Furnace Making a Banging Noise
You may have an urgent problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These involve gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy as time passes, so that’s why it’s essential to set yearly furnace maintenance with Tri County Climate Control LLC. One of the jobs our pros perform during this work is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup may crack your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can discharge carbon monoxide, which is regularly vented outside. This dangerous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Tri County Climate Control LLC advises turning it off and calling us at 541-238-2797. Too much natural gas in your furnace or a cracked heat exchanger are hazardous problems that require fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air around your residence. If the ductwork wasn’t installed properly or is getting dated, it can be loud when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Contact Tri County Climate Control LLC at 541-238-2797 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or chilly air throughout your space, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it can be related to something small, like an unsecure screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating pros at 541-238-2797 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 trying to tell you it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We know that maintenance often slips your mind, but our technicians 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 likely due to an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing noise, Tri County Climate Control LLC can provide support. It’s essential to get loose ductwork repaired fast, as it can result in comfort problems in your house and inflate your energy 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 racket typically means there’s a problem with your furnace’s blower. Switch off your furnace off now and call us at 541-238-2797 for help.
