When your furnace is running properly, it should provide heat without creating too much noise. While it’s expected to catch your furnace making noise as it begins running, other noises are indicating your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating specialists are here to assist with the best furnace repair in Lancaster, Ohio.
1. Furnace Making a Banging Noise
You could have an urgent situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s important to set seasonal furnace maintenance with Fairfield Heating & Cooling. One of the jobs our technicians do during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The subsequent gas buildup might crack your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can leak carbon monoxide, which is regularly emitted away from your home. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Fairfield Heating & Cooling advises turning it off and calling us at 740-331-4331. Significant natural gas in your furnace or a broken heat exchanger are serious issues that should get immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver hot air around your house. If the ductwork wasn’t put in correctly or is getting dated, it can make a lot of noise when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Fairfield Heating & Cooling at 740-331-4331 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes heated or cold air across your house, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be due to something little, like a loose screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and calling our heating professionals at 740-331-4331 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We know 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 detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing noise, Fairfield Heating & Cooling can help. It’s important to get loose ductwork repaired quickly, because it can create comfort problems in your residence and drive up your gas expenses.
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 usually means there’s trouble with your furnace’s blower. Switch off your furnace off right away and contact our pros at 740-331-4331 for help.
