When your furnace is working properly, it should give heat without creating too much noise. While it’s expected to notice your furnace making noise as it turns on, other noises are indicating your furnace needs immediate professional assistance.
Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating professionals are here to help with the best furnace repair in Des Moines, Iowa.
1. Furnace Making a Banging Noise
You could 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 may indicate there could be several problems. These include gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s important to schedule routine furnace maintenance with Kohles & Bach Heating & Cooling. One of the jobs our pros do during this appointment is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise when ignition is delayed. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can discharge carbon monoxide, which is normally vented outdoors. This toxic gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Kohles & Bach Heating & Cooling urges you to turn it off and calling us at 515-207-6569. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous problems that require immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air around your house. If the ductwork wasn’t put in properly or is getting dated, it can make a lot of noise when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Kohles & Bach Heating & Cooling at 515-207-6569 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the proper voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or cold air across your residence, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be due to something minor, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and calling our heating professionals at 515-207-6569 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to tell you it needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our pros can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still noticing noise, Kohles & Bach Heating & Cooling can help. It’s critical to get loose ductwork taken care of fast, as it can result in comfort troubles in your home and drive up your energy costs.
6. Furnace Making a Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal noise usually means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and reach us at 515-207-6569 for support.
