1. Furnace Making a Banging Noise
You could have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These include gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s important to schedule routine furnace maintenance with Service Max Heating & Air Conditioning. One of the jobs our technicians perform during this appointment is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise if ignition takes more time. The resulting gas buildup might break your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can leak carbon monoxide, which is regularly emitted outside. This dangerous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Service Max Heating & Air Conditioning recommends turning it off and reaching us at 360-255-5857. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous problems that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move hot air throughout your residence. If the ductwork wasn’t put in correctly or is aging, it can make a lot of noise when your furnace is on. This might be the case if your furnace makes a banging noise when it shuts off. Contact Service Max Heating & Air Conditioning at 360-255-5857 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cooled air across your residence, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be related to something little, like a loose screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and calling our heating pros at 360-255-5857 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be dilapidated or a bearing may need to be lubed. We realize that maintenance often slips your mind, but our pros can get your furnace heating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing noise, Service Max Heating & Air Conditioning can assist you. It’s essential to get loose ductwork repaired fast, as it can result in comfort issues in your house and inflate your gas expenses.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Switch off your furnace off immediately and call our professionals at 360-255-5857 for help.
