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 couple of problems. These include gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes filthy over the years, so that’s why it’s essential to schedule annual furnace maintenance with H&C Heating and 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 when ignition is delayed. The subsequent 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 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, H&C Heating and Cooling recommends turning it off and contacting us at 301-960-3247. Significant natural gas in your furnace or a broken heat exchanger are serious issues that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide heated air throughout your home. If the ductwork wasn’t put in properly or is getting dated, it can make a lot of noise when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Call H&C Heating and Cooling at 301-960-3247 and we’ll figure out 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 usually means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or chilly air across your residence, and a capacitor, which turns on the motor. If either of these components 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 related to something little, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and calling our heating pros at 301-960-3247 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 skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubricated. We are aware that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again quickly.
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 may also be aware of whistling while the furnace is on if a floor vent is loose. If you’ve examined your vents but are still noticing noise, H&C Heating and Cooling can provide support. It’s critical to get loose ductwork taken care of quickly, since it can make comfort problems in your home and drive up your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise frequently means there’s an issue with your furnace’s blower. Turn off your furnace off right away and reach us at 301-960-3247 for help.
