1. Furnace Makes Banging or Knocking Sounds
You may have a serious issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a few problems. These range from gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over the years, so that’s why it’s important to schedule yearly furnace maintenance with Ameri-Tec. One of the things our technicians complete during this service is clean your furnace’s burners. When this component gets grubby, you may 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 transforms into warm air. Any cracks in it can discharge carbon monoxide, which is regularly vented outside. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Ameri-Tec recommends turning it off and contacting us at 717-479-4950. Too much natural gas in your furnace or a cracked heat exchanger are dangerous issues that should get prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air across your home. If the ductwork wasn’t installed correctly or is getting old, it can be noisy when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Ameri-Tec at 717-479-4950 and we’ll pinpoint the problem.
2. Furnace Buzzes Constantly
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or cold air across your house, 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 Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something minor, like an unsecure screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and contacting our heating specialists at 717-479-4950 for support.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubed. We know that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still sensing sound, Ameri-Tec can help. It’s essential to get loose ductwork repaired without delay, since it can create comfort issues in your home and increase your heating costs.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound frequently means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and reach our pros at 717-479-4950 for support.
