1. Furnace Making a Banging Noise
You might have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty over the years, so that’s why it’s important to book seasonal furnace maintenance with J & J Air Conditioning. One of the things our technicians complete during this appointment is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can discharge carbon monoxide, which is normally released outside. This dangerous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, J & J Air Conditioning advises turning it off and calling us at 254-355-3833. Too much natural gas in your furnace or a cracked heat exchanger are critical problems that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move warm air around your home. If the ductwork wasn’t installed correctly or is getting dated, it can be noisy when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Call J & J Air Conditioning at 254-355-3833 and we’ll determine 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 indicates an electrical situation, 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 might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves hot or cold air across your residence, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be due to something minor, like an unsecure screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and calling our heating pros at 254-355-3833 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to get your attention it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We know 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 hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still sensing noise, J & J Air Conditioning can provide support. It’s important to get loose ductwork repaired quickly, since it can make comfort troubles in your house and inflate your utility bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket usually means there’s a problem with your furnace’s blower. Turn off your furnace off right away and contact us at 254-355-3833 for support.
